Embodiment Construction

[0028] The present invention is described in detail below with reference to the above-mentioned drawings in the form of embodiments. The same technical features are indicated by the same reference numerals in all the drawings.

[0029] figure 1 Shown is a continuous casting machine with a mold 4 and a continuous casting slab guide 11 for supporting, guiding and annealing the continuous casting material, especially cast steel, also referred to below as the continuous casting slab 1. The continuous casting slab 1 according to the present invention is cast into a cross-sectional shape having at least edges 2, 3; see Figures 3 and Figure 4 .

[0030] according to figure 1 The edges 2, 3 on the narrow side of the continuous casting slab 1 in the area of ​​the continuous casting slab guide between the exit of the mold 4 and the correction point of the straightening drive 5 are protected by the use of a large-area porous burner area 6 Heating, especially see figure 1 with figure 2 ....

Abstract

The invention relates to a method and a strand-guiding device for guiding and regulating the temperature of a strand, in particular of steel, in sizes which have at least one edge (2, 3). In this case, the at least one edge (2, 3) is heated by supplying energy in order to avoid stress formation and / or crack formation. Provision is made according to the invention for the edges (2, 3) of the strand (1) to be heated in the strand-guiding region through the use of porous-burner zones (6).

Description

Technical field [0001] The present invention relates to a method for supporting and guiding a continuous casting slab in the form of at least edges for casting, especially for cast steel, and a continuous casting slab guiding device. In order to avoid the formation of stresses and / or cracks during deformation, at least the edges of the continuous casting slab, for example the slab, are heated by the supply of energy. [0002] In particular, the present invention relates to a method and device for the optimal temperature introduction of a continuous casting slab whose cross section is not circular or elliptical, but rectangular or polygonal. Even when the cooling medium is uniformly loaded in this form, due to the two-dimensional heat dissipation on the edges, the cooling is more intense than on the wide side of the continuous casting slab. This effect can be greatly enhanced by unsuitable or unadjustable secondary cooling. In addition, peritectic and microalloyed thick steel plate...
