Definitions
- the invention relates to a method for producing long-steel products according to the preamble of claim 1 and a continuous casting mold for the process.
- the minimum intake speed at the inlet of the rolling train should under no circumstances be less than 4.2 m / min in order not to thermally overload the rollers due to the long contact time with the rolling stock.
- the billet should have at the inlet of the rolling mill suitable for rolling temperature both at the surface and in the core (1 150-1250 0 C).
- the surface temperature should be distributed as homogeneously as possible.
- the billet and billet strands produced by rapid continuous casting can be fed directly to a rolling train without additional heating.
- the mold cavity of this continuous casting mold has at the inlet end of the mold along a circumferential line of its cross section at least two circumferential sections which each limit a cross-sectional enlargement of the mold cavity relative to the corresponding peripheral sections of the mold cavity cross section at the strand exit end of the mold in the form of protrusions.
- the arc heights of the bulges are reduced in the strand running direction such that during casting a strand shell forming in the mold cavity deforms as it passes through the mold, thereby ensuring uniform cooling and shell growth or a homogeneous temperature distribution along the circumference of the strand direct introduction into the rolling train allowing high continuous casting speed is possible.
- the temperature conditions in the foundry strand suitable at the outlet of the casting plant for the introduction into the rolling train if necessary, a temperature regulation can be provided, but no heating is necessary.
- the circumference of an approximately circular cavity section is divided on the pouring side in at least three substantially equal circumferential portions and each of these peripheral sections has on the pouring the Querterrorismsver- enlargement of the mold cavity as a bulge.
- the arc heights of the bulges are reduced on all peripheral sections in the strand direction at least along a partial length of the mold cavity.
- the peripheral line of a polygonal, preferably quadrangular cavity section on the pouring side has circumferential sections with cross-sectional enlargements of the mold cavity in the form of bulges between all corners and the arc heights of the bulges are reduced on all circumferential sections in the strand running direction at least along a partial length of the mold cavity.
- the inventive method for producing long-steel products in which the billets and Vorblockstrlinde generated in the continuous casting mold directly - fed without additional heating - a rolling train and there rolled into long products, allows a simple system configuration and a cost-effective operation.
- Fig. 1 is a schematic representation of a working according to the inventive continuous casting plant with a rolling train.
- Fig. L shows schematically the structure of a known continuous casting 10 with a ladle 1, an intermediate vessel 2 (Tundish), cooled with water mold 3, and a Strandumlenk noticed 6 for the strand 5, which pulled by means of rollers 6 'and in the Horizontal bent. Thereafter, the strand 5 according to the invention is fed directly to a rolling train 20, which has a plurality of rolling units 21 with rolling rolls 22, which is not shown in detail since such rolling trains 20 or rolling mills are known.
- a mold cavity 3 'of this mold 3 has at the inlet end of the mold along a circumferential line of its cross section at least two peripheral portions, each having a cross-sectional enlargement of the mold. cavity 3 'with respect to the corresponding peripheral portions of the mold cavity cross-section at the strand outlet end of the mold 3 limit in the form of bulges, which is not illustrated in detail.
- the continuous casting speed of the strand 5 is advantageously at least 4.2 m / min in order not to exceed the permissible contact time between the strand and the rolls at the inlet of the rolling train and thereby not to shorten their durability unreasonable.
- the temperature conditions at the outlet of the continuous casting plant 10 for the introduction into the rolling train are precisely adapted so that the rolling of the strand can be carried out in an optimal manner. At most, however, a passive temperature compensation, without external energy supply can be made.
- the mold cavity cross section of the continuous casting mold is essentially formed as a four-round format.
- This four-round format is based on a square or rectangle, but it is provided in the corners with relatively large radii. Strand exit side, these radii in the corner regions are advantageously approximately 20 to 40 mm at a length or width of the mold cavity cross-section of 120 to 180 mm.
- an edge rounding of about 25 mm and the continuous casting speed of at least 5.2 m / min and correspondingly in a four-round format of 180 mm an edge rounding of about 40 mm and casting speed of at least 4.2 m / min could be provided.
- a conventional control element preferably a sliding closure 15, is provided in the mold for the purpose of precise inflow control of the molten steel to be discharged.
- a regulation of the filling level of the melt in the mold 3 takes place as a function of the inlet speed in the first rolling stand (so-called master slave operation), for which a control device 13 and a filling level measuring device 14 are provided in the mold 3.
- This regulation is intended to achieve an approximately constant filling level in the mold.
- a refractory dip tube attached to the inflow control element and protruding into the mold is advantageous, so that the bath surface in the mold is as smooth as possible.
- the cast billet strands essentially form a four-round format and their fillet is selected according to the format such that, if the casting speed is sufficiently high, a strand is produced having a temperature distribution required for rolling, which can be directly rolled without any active reheating, i. the cast strands are fed endlessly to the rolling train without being cut into pieces.
