Definitions
- the invention relates to a continuous casting apparatus according to the preamble of claim 1 for the casting of liquid metals, in particular of steel materials, with billet, block, billet, carrier pre-profile, round or polygon strand format.
- From the DE 43 18 105 A1 is a mold for the continuous casting of metal, in particular of steel in billet and billet cross sections known, with regularly distributed cross-sectional enlargements in the form of bulges.
- the extent of the bulges decreases at least along a partial length in the strand running direction such that the strand cross-sectional shape deforms during passage through the partial length.
- this measure only aims to be able to use water jackets as a tubular body with substantially parallel walls.
- From the EP 1 088 610 is a continuous casting with a continuous casting mold for casting of liquid metals in a strand format, in particular steel materials known.
- the cross section of the mold on two opposite flat and mutually parallel sides and two other cross-sectionally opposite sides with recesses in their corner areas.
- the recesses extend to the flat sides and form opposite elevations.
- the continuous casting apparatus has a support roller stand adjoining the continuous casting mold and a reduction area with deformation rollers for deforming the elevations back.
- the embodiment of the EP 1 088 610 corresponds to a block shape substantially of the type described above.
- the invention has the object of developing a known continuous casting to the effect that even in the interior of their continuous casting a guide for so-called. Long products is provided and that the continuous casting of increasing quality requirements, the core zones of the casting strand, sufficient.
- the object is achieved by means of the above-mentioned continuous casting with continuous casting mold according to the invention in that the recesses are square or rectangular; that the elevations are associated with the fixed side and the loose side of the support roll stand, wherein the strand format is stably guided by means of the increase in the support roll stand and that the reduction region is a hard reduction region for compressing the cast strand format without a liquid swamp its complete solidification.
- the advantage is initially a stable guidance of the long product by parallel surfaces, a uniform roller contact and a required symmetry position of the casting strand in the continuous casting mold and in the support roll stand. Then, a mechanical in-line deformation is performed by the claimed hard reduction, whereby the inner quality of the strand can be improved.
- the cast strand is compressed after its complete through solidification, density variations over the strand cross section due to the solidification process being compensated.
- the continuous casting a continuous casting mold 1 with a mold length 1a and is located to the lower level at a height 2, in which the filling level 3 is above the neutral Kokillenachse.
- the Badaptiere 4 is at the level of height 2.
- the horizontal length 6 is dimensioned at the point of reference and the plant total length 7 extends to the end of a driving and straightening area. 8
- the following on the continuous casting mold 1 support roller frame 9 is composed in the embodiment of a first segment 10, a subsequent second segment 11, a third segment 12 and a fourth segment 13.
- elevations 33 and elevations are respectively provided on the fixed side 5a and on the loose side 5b of the support roller stand 9, which elevations are later deformed again relative to each other by re-deformation in the hard reduction region 8a.
- the opposite in cross-section 21 sides 21a, 21b are formed flat and substantially parallel to each other and two perpendicular thereto, opposite sides 22a, 22b (Fig. 2B) have 35 recesses 36 in the corner regions, which also into the flat sides 21a, 21b. This results in square or rectangular recesses 36, which can be simplified rounded and also give the increases or elevations 33.
