Abstract
The invention discloses a penetration preventing steel ladle which comprises a steel shell and a refractory material casting layer, wherein a ladle bottom precast block brick capable of resisting the erosion of the molten steel is arranged in the refractory material casting layer at the bottom molten steel injection position of the ladle. As the ladle bottom precast block brick capable of resisting the erosion of the molten steel is arranged in the refractory material casting layer at the bottom molten steel injection position of the ladle, the quick melting loss of the refractory material casting layer at the molten steel injection position can be effectively avoided, thereby preventing the occurrence of the steel penetration accidents; and meanwhile, the service life of the ladle can be prolonged.
Description
Technical field:
The present invention relates to a kind of steel-making and use ladle, particularly a kind of antiseepage steel ladle.
Background technology:
Ladle is used for accepting molten steel from converter or electric furnace in the process for making process, and it generally comprises box hat and refractory material casting layer, and when molten steel is poured in the ladle with certain pressure, flow velocity, impouring angle, its molten steel falls into a little always in a fixing scope.Like this ladle again and again accept molten steel the time.Near its molten steel falls into a little refractory material casting layer always than other position of ladle bottom refractory material casting layer melting loss fast, when melting loss acquires a certain degree, cause the steel accident of oozing easily.
Summary of the invention:
Technical problem to be solved by this invention provides a kind of antiseepage steel ladle, and it comprises box hat and refractory material casting layer, wherein, is provided with prefabricated section brick at the bottom of the ladle of anti-molten steel scouring in the refractory material casting layer of said ladle bottom molten steel injection phase.
The present invention's technical characterictic further is:
The prefabricated section brick is aluminium carbon or aluminium zirconium carbon material at the bottom of the said ladle.
The prefabricated section brick comprises refractory aggregate, body upper surface, body lower surface and body side at the bottom of the said ladle, and wherein the body side is provided with the above dislocation platform at least three roads.
Prefabricated section brick body side is provided with three roads dislocation platform at the bottom of the said ladle.
Prefabricated section brick body side is provided with four roads dislocation platform at the bottom of the said ladle.
Prefabricated section brick body side is provided with five roads dislocation platform at the bottom of the said ladle.
The present invention also provides prefabricated section brick at the bottom of a kind of ladle; Comprise refractory aggregate, body upper surface, body lower surface and body side; Wherein, said refractory aggregate is aluminium carbon or aluminium zirconium carbon material, and the body side is provided with the above dislocation platform at least three roads.
Prefabricated section brick technical characterictic further is at the bottom of this ladle:
Prefabricated section brick body side is provided with three roads dislocation platform at the bottom of the said ladle.
Prefabricated section brick body side is provided with four roads dislocation platform at the bottom of the said ladle.
Prefabricated section brick body side is provided with five roads dislocation platform at the bottom of the said ladle.
The invention has the beneficial effects as follows:
Owing to prefabricated section brick at the bottom of the ladle that is provided with anti-molten steel scouring in the refractory material casting layer of ladle bottom molten steel injection phase; Therefore can effectively prevent the very fast melting loss of refractory material casting layer of molten steel injection phase; Thereby avoid causing the generation of oozing the steel accident, also can prolong the service life of ladle simultaneously.
Description of drawings:
Fig. 1 is the partial sectional view of antiseepage steel ladle one embodiment of the present invention;
Fig. 2 is the lateral plan of prefabricated section brick one embodiment at the bottom of the ladle.
The specific embodiment:
Below in conjunction with accompanying drawing the present invention is done further explanation:
As depicted in figs. 1 and 2, a kind of antiseepage steel of the present invention ladle, it comprises box hat 1 and refractory material casting layer 2, wherein, is provided with prefabricated section brick 3 at the bottom of the ladle of anti-molten steel scouring in the refractory material casting layer 2 of said ladle bottom molten steel injection phase.
The present invention is in practical application:
Prefabricated section brick 3 is aluminium carbon or aluminium zirconium carbon material at the bottom of the said ladle.
Prefabricated section brick 3 comprises refractory aggregate 301, body upper surface 302, body lower surface 303 and body side 304 at the bottom of the said ladle, and wherein body side 304 is provided with the above dislocation platform at least three roads.In the embodiment shown in Figure 2, prefabricated section brick body side is provided with four roads dislocation platform at the bottom of the said ladle, can certainly be three roads dislocation platform.For better preventing to ooze the generation of steel accident, prefabricated section brick body side can also be provided with five roads dislocation platform or six roads dislocation platform at the bottom of the said ladle.
Owing to prefabricated section brick 3 at the bottom of the ladle that is provided with anti-molten steel scouring in the refractory material casting layer of ladle bottom molten steel injection phase; Therefore can effectively prevent the very fast melting loss of refractory material casting layer of molten steel injection phase; Thereby avoid causing the generation of oozing the steel accident; Also can prolong simultaneously the service life of ladle, and since at the bottom of the ladle prediction block brick periphery be that body side 304 is provided with the above dislocation platform at least three roads, even if like this at the bottom of ladle prefabricated section brick and refractory material casting layer junction steel appears oozing; The route of molten steel walking also can be into S type or multistage S type; Craspedodrome has become S type passage, more can avoid the further infiltration of molten steel, thereby can avoid the generation of ladle seepage steel accident.。
Though the present invention has described the specific embodiment herein, coverage of the present invention is not limited thereto.On the contrary, all technical schemes in all scopes that drop on claim on literal or under the instruction in equivalents are in fact contained in the present invention.Protection scope of the present invention is as the criterion with claims.
