Problems solved by technology

[0007] - a relatively high casting speed and thus a high cooling power due to secondary cooling, resulting in a larger spray volume and a larger cross-section of the spray pipe of the nozzle,
[0008] The disadvantage is that due to the small roll distance and the small available space, the accessibility of the roll frame is directly poor, so that the continuous casting strand guide segment (which contains the roll frame) of the strand guide frame is maintained. higher cost

Embodiment Construction

[0048] figure 1 A slab guide segment 1 of an arc-shaped continuous casting plant is shown in section, which has a figure 1 ) of the roll stand 2. As usual in continuous casting, liquid steel is cast in a mold (not shown), wherein the liquid steel is cooled and forms an at least partially solidified strand in the mold. Subsequently, the slab is pulled out of the mold, the slab is supported in a slab support device comprising a plurality of slab guide segments 1 behind the mould, and in the slab support Guided and further cooled in the unit. In the strand guide segment 1 , the strand in the form of a slab 6 is supported by a plurality of strand guide rollers 8 on each of a roll stand 2 . Each roll stand 2 has a rectangular closed frame 7 consisting of three transverse beams 13 arranged transversely to the casting direction 5 and of six longitudinal plates 16 arranged in the casting direction 5 , wherein the frame 7 is formed by means of The beams 13 and the longitudinal plat...

Abstract

The roller support (2) for supporting three strand guide rollers (8) in a strand guide segment (1) of a strand casting machine for casting a strand with slab or thin slab cross-section, comprises a closed frame (7), which is formed from transverse bars or transverse ridges and longitudinal bars (15) or longitudinal ridges (16), and two bearing blocks (12). The invention aims to improve the maintainability of the strand guide segment (1) through the rigidity of the roller support (2) and the structure of space saving of the roller support (2). Specifically, the aim can be achieved by uninstalling or installing a single spray nozzle (9) and a jet pipe (10) on the premise that the strand guide segment (1) is relatively compact and installed for a short time. The frame (7) together with the longitudinal bars (15) or longitudinal ridges (16) forms a lattice-like structure with mesh windows (17). The mesh windows (17) are formed for accommodating two spray nozzles (9) for cooling the strand.

Description

technical field [0001] The invention relates to a roll stand for supporting at least three strand guide rolls in a strand guide segment of a continuous casting machine for casting steel products with Continuous casting slab of slab or thin slab cross-section. Background technique [0002] In particular, the invention relates to a roll stand for supporting at least three strand guide rolls in a strand guide segment of a continuous caster for casting slabs having A continuously cast slab of billet or thin slab cross-section, said roll stand comprising: [0003] - a closed frame consisting of a plurality of beams or transverse plates and of a plurality of longitudinal beams or longitudinal plates, wherein the transverse beams or transverse plates are arranged transversely to the casting direction and the longitudinal beams or longitudinal plates are arranged along the casting direction; [0004] - in each case at least two bearing blocks for supporting strand guide rolls arra...
