Definitions
- This invention concerns a downstream mould portion with thin sidewalls for continuous casting, as set forth in the main claim.
- the downstream mould portion according to the invention is employed in the continuous casting of thin and medium slabs, billets, blooms, etc. having a round, square, polygonal or any other analogous cross-section in general.
- the state of the art includes the provision of a downstream mould portion at the outlet of, and in prolongation of, the oscillatory crystallizer which defines the specific form of the cast slab, this downstream mould portion including an intensive cooling system.
- cooling fluid is delivered directly into contact with the solidified skin of the slab.
- the state of the art includes various types of downstream mould portions employed for the formation of slabs having a square or rectangular cross-section or of slabs having a round cross-section.
- the former slabs are generally shaped with four or more elements or plates arranged as the sides of a square and separated at the angles where they converge.
- the latter slabs are shaped with shell elements arranged according to a circumference, as can be seen in EP-A-0268143 for instance.
- US-A-2,698,467 discloses a downstream mould portion with helicoidal grooves on its periphery; this document, however, does not teach how to adjust the dimensions of the downstream mould portion to the actual dimensions of the slab passing through nor how to ensure the desired pressure against the slab.
- EP-A-0367024 in the name of the present applicants teaches the provision of a downstream mould portion consisting of a plurality of independent, movable and self-aligning elements, whereby the sides of each element together with those of the neighbouring element define clefts having a development not parallel to the axis and surface of the solidifying slab.
- Patent CH-B-357.835 discloses downstream mould portion devices with a cooling chamber with a circulation of cooling fluid, the sidewall in contact with the product leaving the mould being characterised by a surface extending within the cooling chamber; this extending surface stiffens the sidewall itself of the downstream mould portion.
- the purpose of the invention is to embody a downstream mould portion applied to a continuous casting mould, in which it is possible to carry out a high-efficiency accelerated and intensive cooling.
- the downstream mould portion consists of several elements the intersection of the surfaces of which defines a closed cross-section substantially analogous to the cross-section of the slab, billet or bloom passing through.
- Each of the elements forming the downstream mould portion has a box-shaped structure defined by an outer sidewall and an inner sidewall.
- These inner and outer sidewalls define between them a second chamber for circulation of a cooling fluid under pressure.
- the inner sidewall of the downstream mould portion namely the sidewall facing towards the slab passing through, has a conformation such as to make its behaviour resilient and, according to the invention, a very modest thickness of the order of 4 to 10 mm. but advantageously about 5 to 6 mm.
- the natural tendency to the outward deformation of the inner sidewall owing to the very high temperatures involved and the modest thickness is counterbalanced by the inward pressure of the cooling fluid circulating within the second fluid circulation chamber.
- This pressure of the cooling fluid therefore depends on the thrusts and outward deformations of the inner sidewall due to the overheating.
- the pressure of the cooling fluid against the inner sidewall causes a resilient inward thrust, counterbalances the tensions due to deformation by overheating and keeps the inner sidewall, in fact, adhering to the solidifying skin of the slab.
- each element forming the downstream mould portion consists in turn of a plurality of substantially vertical panels associated with one another.
- the corners of the slab are not cooled by the cooling fluid circulating in the chamber of the downstream mould portion, the purpose being to minimise the lengthwise cracks in the surface of the slab.
- the corners of the slab may be partly cooled, for instance by the delivery of jets of water.
- At least the side of the outer sidewall facing the second chamber holding the circulating cooling fluid under pressure is shaped and conformed in a manner so as to break up the fluid streams of the outermost layer of the cooling fluid, thus forcing and making swirling the motion of the cooling fluid and improving the heat exchange.
- a plurality of hollows or other agitation elements are provided in the side of the inner sidewall of the downstream mould portion facing towards the second chamber holding the circulating cooling fluid and break up the outermost surface layer of the fluid, thus causing a further accentuation of the heat exchange.
- a plurality of enlargements and narrowings is provided on the side of the outer sidewall of the downstream mould portion facing towards the second chamber for the circulation of a cooling fluid and imparts to the fluid a turbulent and swirling motion.
- the elements forming the downstream mould portion according to the invention are advantageously associated with resilient pressure means ,which are known in themselves and are suitable to maintain continuously the contact with the slab passing through.
- a downstream mould portion 10 according to the invention is applied to a mould 11 comprising an oscillatory crystallizer 12, within which is located a discharge nozzle 13, the outlet of which is generally positioned below the meniscus of molten metal.
- the crystallizer 12 cooperates with a closed-circuit primary cooling system that comprises a first chamber 23 for circulation of the cooling fluid, this first chamber 23 being adjacent to the crystallizer sidewall facing the molten metal.
- a first thickness 14 of solidified skin is formed in the slab 22 within the crystallizer 12, whereas the core 15 of the cast slab remains substantially liquid.
- the downstream mould portion 10 according to the invention is positioned at the outlet of, and in prolongation of, the crystallizer 12.
- the downstream mould portion 10 consists of four elements 10a arranged about the periphery of the slab 22 and defining a passage having a cross-section of dimensions substantially mating with the cross-section of the slab 22 itself.
- the cast product has a substantially square cross-section
- the cross-section of the product is substantially rectangular.
- Each element 10a possesses a box-shaped structure comprising a first outer sidewall 16 and a second inner sidewall 17, these sidewalls 16-17 defining between them one or more second chambers 18 for the circulation of a cooling fluid under pressure.
- the outer sidewall 16 is associated with at least one conduit 20 to feed a cooling fluid under pressure and at least one conduit 19 to discharge cooling fluid under pressure, the conduits 19-20 being associated with means 28 that adjust and close the flow of fluid.
- the inner sidewall 17 faces the slab 22 passing through and has a very modest thickness of about 4 to 10 mm., but advantageously about 5 to 6 mm.
- the natural tendency of the inner sidewall 17 to become deformed outwards owing to the very great heat exchange with the slab 22 passing through, this tendency being accentuated by the modest thickness of the inner sidewall 17 itself, is compensated by acting on the pressure of the cooling fluid circulating within the second chamber 18.
- This pressure acts against the inner sidewall 17 and causes a resilient thrust towards the slab 22, thus counterbalancing the thrusts due to deformation and, in fact, maintaining the inner sidewall 17 in a condition of adherence to the solidified skin 14 of the slab 22.
- the side of the outer sidewall 16 facing the second chamber 18 for circulation of the cooling fluid is shaped and conformed to break up the fluid stream and thus to make swirling the movement of the cooling fluid and to increase the coefficient of the heat exchange between the cooling fluid and the inner sidewall 17 of the downstream mould portion 10.
- the conformation provides alternate narrowed areas 26 and enlarged areas 27 for the purpose of causing in the circulating fluid a desired turbulence.
- enlarged areas 27 and narrowed areas 26 may have a polygonal development (Fig.5) or a development producing a Venturi effect (Fig.2), which makes the motion of the fluid swirling and accentuates the heat exchange.
- the side of the inner sidewall 17 facing the second chamber 18 for the circulation of fluid includes a plurality of agitation elements shaped in this case as cavities 21, into which the cooling fluid enters, thus breaking up the outermost layer of the fluid and causing a further accentuation of the heat exchange.

Abstract
Description
- This invention concerns a downstream mould portion with thin sidewalls for continuous casting, as set forth in the main claim.
- The downstream mould portion according to the invention is employed in the continuous casting of thin and medium slabs, billets, blooms, etc. having a round, square, polygonal or any other analogous cross-section in general.
- In the description that follows we shall speak preferably of slabs but will mean thereby that the downstream mould portion of this invention is applied to all types of products produced by continuous casting, as indicated above.
- The problems concerning the cooling of cast slabs are well known in the continuous casting process. In fact, this cooling should achieve a compromise as regards the solidifying of the cast slab as quickly as possible without creating tensions in the skin being formed.
- These tensions often lead to the occurrence of cracks and deformations in the solidified skin, and these cracks and deformations impair the level of quality of the finished product.
- The state of the art includes the provision of a downstream mould portion at the outlet of, and in prolongation of, the oscillatory crystallizer which defines the specific form of the cast slab, this downstream mould portion including an intensive cooling system.
- In this downstream mould portion the slab passing through undergoes a quick removal of heat owing to the action of high-efficiency cooling means.
- In some cases the cooling fluid is delivered directly into contact with the solidified skin of the slab.
- This type of intensive cooling, owing to the inclusion of a liquid core in the slab, leads to the creation of a heterogeneous crystalline structure which may be the source of a plurality of shortcomings such as fragility of the slab, the formation of cracks owing to internal tensions, a scanty coherence in the central zone and yet other drawbacks.
- All these shortcomings have an unfavourable effect on the employment and subsequent processings of the product thus obtained.
- The state of the art includes various types of downstream mould portions employed for the formation of slabs having a square or rectangular cross-section or of slabs having a round cross-section.
- The former slabs are generally shaped with four or more elements or plates arranged as the sides of a square and separated at the angles where they converge.
- The latter slabs are shaped with shell elements arranged according to a circumference, as can be seen in EP-A-0268143 for instance.
- US-A-2,698,467 discloses a downstream mould portion with helicoidal grooves on its periphery; this document, however, does not teach how to adjust the dimensions of the downstream mould portion to the actual dimensions of the slab passing through nor how to ensure the desired pressure against the slab.
- EP-A-0367024 in the name of the present applicants teaches the provision of a downstream mould portion consisting of a plurality of independent, movable and self-aligning elements, whereby the sides of each element together with those of the neighbouring element define clefts having a development not parallel to the axis and surface of the solidifying slab.
- This disclosure, while being satisfactory, does not overcome the problems fully, is complex to construct, use and maintain and does not ensure a fully efficient level of cooling.
- Patent CH-B-357.835 discloses downstream mould portion devices with a cooling chamber with a circulation of cooling fluid, the sidewall in contact with the product leaving the mould being characterised by a surface extending within the cooling chamber; this extending surface stiffens the sidewall itself of the downstream mould portion.
- The present applicants have designed, tested and embodied this invention to overcome the problems which have been the subject of complaints in the state of the art and to achieve further advantages.
- This invention is set forth and characterised in the main claim, while the dependent claims describe variants of the idea of the main embodiment.
- The purpose of the invention is to embody a downstream mould portion applied to a continuous casting mould, in which it is possible to carry out a high-efficiency accelerated and intensive cooling.
- According to the invention the downstream mould portion consists of several elements the intersection of the surfaces of which defines a closed cross-section substantially analogous to the cross-section of the slab, billet or bloom passing through.
- Each of the elements forming the downstream mould portion has a box-shaped structure defined by an outer sidewall and an inner sidewall.
- These inner and outer sidewalls define between them a second chamber for circulation of a cooling fluid under pressure.
- According to the invention the inner sidewall of the downstream mould portion, namely the sidewall facing towards the slab passing through, has a conformation such as to make its behaviour resilient and, according to the invention, a very modest thickness of the order of 4 to 10 mm. but advantageously about 5 to 6 mm.
- According to the invention the natural tendency to the outward deformation of the inner sidewall owing to the very high temperatures involved and the modest thickness is counterbalanced by the inward pressure of the cooling fluid circulating within the second fluid circulation chamber.
- This pressure of the cooling fluid therefore depends on the thrusts and outward deformations of the inner sidewall due to the overheating.
- The pressure of the cooling fluid against the inner sidewall causes a resilient inward thrust, counterbalances the tensions due to deformation by overheating and keeps the inner sidewall, in fact, adhering to the solidifying skin of the slab.
- This leads to a more constant and uniform nature of the heat exchange between the cooling fluid under pressure and the slab.
- According to a variant each element forming the downstream mould portion consists in turn of a plurality of substantially vertical panels associated with one another.
- According to a further variant the corners of the slab are not cooled by the cooling fluid circulating in the chamber of the downstream mould portion, the purpose being to minimise the lengthwise cracks in the surface of the slab.
- According to yet another variant the corners of the slab may be partly cooled, for instance by the delivery of jets of water.
- According to the invention at least the side of the outer sidewall facing the second chamber holding the circulating cooling fluid under pressure is shaped and conformed in a manner so as to break up the fluid streams of the outermost layer of the cooling fluid, thus forcing and making swirling the motion of the cooling fluid and improving the heat exchange.
- According to a variant a plurality of hollows or other agitation elements are provided in the side of the inner sidewall of the downstream mould portion facing towards the second chamber holding the circulating cooling fluid and break up the outermost surface layer of the fluid, thus causing a further accentuation of the heat exchange.
- According to a further variant a plurality of enlargements and narrowings is provided on the side of the outer sidewall of the downstream mould portion facing towards the second chamber for the circulation of a cooling fluid and imparts to the fluid a turbulent and swirling motion.
- The elements forming the downstream mould portion according to the invention are advantageously associated with resilient pressure means ,which are known in themselves and are suitable to maintain continuously the contact with the slab passing through.

- A
downstream mould portion 10 according to the invention is applied to amould 11 comprising anoscillatory crystallizer 12, within which is located adischarge nozzle 13, the outlet of which is generally positioned below the meniscus of molten metal. - The
crystallizer 12 cooperates with a closed-circuit primary cooling system that comprises afirst chamber 23 for circulation of the cooling fluid, thisfirst chamber 23 being adjacent to the crystallizer sidewall facing the molten metal. - A
first thickness 14 of solidified skin is formed in theslab 22 within thecrystallizer 12, whereas thecore 15 of the cast slab remains substantially liquid. - The
downstream mould portion 10 according to the invention is positioned at the outlet of, and in prolongation of, thecrystallizer 12. - In the example shown in Figs.3 and 4 the
downstream mould portion 10 consists of fourelements 10a arranged about the periphery of theslab 22 and defining a passage having a cross-section of dimensions substantially mating with the cross-section of theslab 22 itself. - In particular, in the example of Fig.3 the cast product has a substantially square cross-section, whereas in the example of Fig.4 the cross-section of the product is substantially rectangular.
- Each
element 10a possesses a box-shaped structure comprising a firstouter sidewall 16 and a secondinner sidewall 17, these sidewalls 16-17 defining between them one or moresecond chambers 18 for the circulation of a cooling fluid under pressure. - The
outer sidewall 16 is associated with at least oneconduit 20 to feed a cooling fluid under pressure and at least oneconduit 19 to discharge cooling fluid under pressure, the conduits 19-20 being associated with means 28 that adjust and close the flow of fluid. - The
inner sidewall 17 faces theslab 22 passing through and has a very modest thickness of about 4 to 10 mm., but advantageously about 5 to 6 mm. - According to the invention the natural tendency of the
inner sidewall 17 to become deformed outwards owing to the very great heat exchange with theslab 22 passing through, this tendency being accentuated by the modest thickness of theinner sidewall 17 itself, is compensated by acting on the pressure of the cooling fluid circulating within thesecond chamber 18. - This pressure acts against the
inner sidewall 17 and causes a resilient thrust towards theslab 22, thus counterbalancing the thrusts due to deformation and, in fact, maintaining theinner sidewall 17 in a condition of adherence to thesolidified skin 14 of theslab 22. - This makes it possible also to keep constant and uniform the heat exchange between the cooling fluid and the
slab 22, this heat exchange reaching very high values in view of the very modest thickness of theinner sidewall 17. - According to the invention the side of the
outer sidewall 16 facing thesecond chamber 18 for circulation of the cooling fluid is shaped and conformed to break up the fluid stream and thus to make swirling the movement of the cooling fluid and to increase the coefficient of the heat exchange between the cooling fluid and theinner sidewall 17 of thedownstream mould portion 10. - In the embodiment shown in Figs.2 and 5 the conformation provides alternate narrowed
areas 26 and enlargedareas 27 for the purpose of causing in the circulating fluid a desired turbulence. - These
enlarged areas 27 and narrowedareas 26 may have a polygonal development (Fig.5) or a development producing a Venturi effect (Fig.2), which makes the motion of the fluid swirling and accentuates the heat exchange. - According to a variant the side of the
inner sidewall 17 facing thesecond chamber 18 for the circulation of fluid includes a plurality of agitation elements shaped in this case ascavities 21, into which the cooling fluid enters, thus breaking up the outermost layer of the fluid and causing a further accentuation of the heat exchange. - According to the invention the
cavities 21 may have a horizontal or substantiallyhorizontal development 21a or aninclined development 21b (Fig.7). - Each
element 10a of thedownstream mould portion 10 includessprings 24, which are associated with a stationary supportingstructure 25 and are suitable to maintain contact between theinner sidewall 17 and theslab 22 passing through and to exert a desired pressure against theslab 22. - According to the variant of Fig.4 each
element 10a forming thedownstream mould portion 10 is embodied with a plurality of verticaladjacent panels 110, each of which includes its own inner 17 and outer 16 sidewalls and asecond chamber 18 for circulation of the cooling-fluid. - These
vertical panels 110, according to a variant, can cooperate independently with the position-adjustment springs 24 for the purpose of providing an independent adaptation of one to the other.
