Definitions
- a liquid-cooled mold of the type in question is used for the continuous casting of thin steel slabs, the cross-sectional length of which is a multiple of the cross-sectional width.
- At least each broad side wall is composed of a copper plate delimiting the mold cavity and a steel support plate.
- the copper plate is attached to the support plate by means of transversely protruding metal bolts. To do this, the metal bolts penetrate the holes in the support plate. Extended areas are provided at the end of the holes, in which nuts can be screwed onto the threaded ends of the metal bolts. With their help, the copper plate is pulled firmly to the support plate.
- the invention is based on the object of creating a liquid-cooled mold for high casting speeds, in particular for continuous steel casting close to the final dimensions, in which the strength problems in the area of the connections of the metal bolts to the copper plates are significantly reduced. According to the invention, this object is achieved in the features of claim 1.
- the key point of the invention is the measure of specifically forming the metal bolts from a CuNiFe alloy.
- metal bolts On account of such, in particular hard-drawn, metal bolts, considerable increases in strength are now achieved with only little scatter in the strength in the welded connections to the copper plate.
- This can be made of pure copper, for example SF-Cu, or of a high-temperature resistant copper alloy, e.g. B. consist of a hardenable copper alloy with additions of chromium and / or zirconium.
- the hitherto unsafe handling and the many influencing factors during welding, which involve a 100% inspection, are no longer required.
- the metal bolts consist of a CuNi30Mn1 Fe material.
- the metal studs are welded onto the copper plates using a filler metal.
- nickel is used here as a filler material (claim 5).
- the filler metal can be inserted as a foil between the metal studs and the copper plates. It is also possible to provide the copper plates with the filler metal at the connection points or to coat the end faces of the metal bolts. It is also possible to use nickel rings on the circumference of the metal studs as a filler metal.
- the copper plates of the broad side walls have groove-like coolant channels which run parallel to the casting direction and are covered by the support plates. With the help of such coolant channels, an increased heat transfer from the casting side to the cooling water can be ensured, so that high
- Coolant channels in the copper plates are used in particular when the thickness of the copper plates is sufficient to be able to introduce sufficiently large coolant channels in cross section.
- the copper plates have cooling bores next to the coolant channels parallel to the casting direction and extending in the vertical cross-sectional planes of the metal bolts.
- Such cooling holes can be created by mechanical deep drilling.
- Cooling holes transferred coolant avoids a local temperature rise of the copper plates in the vicinity of the connection areas of the metal bolts with the copper plate in continuous casting operation.
- the cooling bores are preferably arranged in the area of the bathroom mirror.
- the invention according to claim 9 provides that the support plates have groove-like coolant channels running parallel to the casting direction and covered by the copper plates. There are then no coolant channels in the copper plates. If necessary, a combination of coolant channels in the copper plates and in the support plates can also be used.
- the cross section of the mold cavity is dimensioned larger at the end on the pouring side than at the end on the strand exit side.
- the mold cavity has a multiple taper.
- a bulge can be provided at the pour-in end of the mold cavity, which bulges in the casting direction. This bulge is used in particular to hold a dip tube.
- Figure 1 in the schematic in vertical longitudinal section a liquid-cooled mold
- Figure 2 is an enlarged view of a partial view of the back of a
- FIG. 3 shows, on an enlarged scale, a partial horizontal section through a broad side wall of the mold of FIGS. 1 and
- Figure 4 also on an enlarged scale, a partial horizontal section through a broad side wall according to another embodiment.
- FIG. 1 denotes a liquid-cooled mold, only schematically illustrated, for the continuous casting of thin steel slabs, not shown, the cross-sectional length of which is a multiple of the cross-sectional width.
- the mold 1 has two mutually opposing multi-layer broad side walls 2 and two likewise opposing narrow side walls 3, which form a mold cavity 4.
- the broad side walls 2 are provided at the pouring end 5 of the mold cavity 4 with bulges 6 which are continuously deformed downwards along a partial height of the mold 1.
- the cross section of the mold cavity 4 is rectangular and aligned with the desired thin slab cross section.
- the purpose of the two bulges 6 lying opposite one another is to create the space required for a dip tube (not illustrated in more detail) for the supply of the molten metal.
- each broad side wall 2 has a copper plate 8 delimiting the mold cavity 4 and a steel support plate 9.
- the copper plate 8 as can also be seen in FIG. 2 drawn without the support plate 8, groove-like coolant channels 10 running parallel to the casting direction GR and covered by the support plate 9 and to which cooling water can be applied are provided.
- FIGS. 2 and 3 show that cooling bores 11, which can likewise be acted upon by cooling water, extend parallel to the coolant channels 10.
- the cooling bores 11 run in the vertical cross-sectional planes QE of metal studs 12 made of CuNi30Mn1Fe, which are fastened to the rear side 14 of the copper plate 8 by means of the stud welding process using nickel rings 13 as welding filler material.
- the metal bolts 12 pass through bores 15 in the support plate 9.
- By screwing nuts 16 onto the thread ends 17 of the metal bolts 12 the copper plate 8 is pulled towards the support plate 9 and fixed to it.
- the nuts 16 lie in enlarged end sections 18 of the bores 15.
- the coolant is fed into the cooling bores 11 via the coolant channels 10, and expediently, as shown in FIG. 2, via a branch 19 between a cooling bore 11 and the adjacent coolant channel 10.
- FIG. 3 also shows that the coolant channels 10, in addition to the cross-sectional planes QE of the metal bolts 12, are formed deeper than the other coolant channels 10.
- the arrangement of coolant channels 10 and cooling bores 11 in a copper plate 8 takes place when the copper plate 8 has a sufficient thickness D.
- coolant channels 10a according to FIG. 4 are worked into the support plate 9a and covered by the copper plate 8a when the copper plate 8a is fixed to the support plate 9a with the help of the metal bolts 12.
