Problems solved by technology
[0004] For large special-shaped slabs, the web of the slab is relatively wide, so the straightening force required for web straightening is relatively large; if the straightening force required for the web of the slab is close to or greater than the connection between the flange of the slab and the web If the shear force can be tolerated, deformation or cracks may appear at the connection between the slab flange and the web, which will affect the quality of the slab, and even make the slab an unqualified waste slab

The large special-shaped blank withdrawal and straightening machine comprises a rack (11), an upper roller (12) and a lower roller (13), the upper roller (12) and the lower roller (13) are both located in the rack (11), the upper roller (12) is sleeved with a web upper supporting roller (17), the length of the web upper supporting roller (17) is smaller than that of an outer roller face (124) of the upper roller, the web upper supporting roller (17) is detachably connected with the upper roller (12), and the web upper supporting roller (17) is detachably connected with the lower roller (13). The web upper supporting roller (17) can make contact with the upper surface of a web (21) of the special-shaped casting blank (20). In the working process, the web upper supporting roller of the large special-shaped blank withdrawal and straightening machine can make direct contact with a web of a special-shaped casting blank, straightening force is directly transmitted, and the quality defect caused by too large stress at the connecting position of a flange and the web is avoided.
Description
technical field [0001] The invention relates to the technical field of continuous casting equipment, in particular to a large-scale special-shaped blank drawing and straightening machine, and a continuous casting machine. Background technique [0002] On the arc continuous casting machine in the metallurgical industry, the tension leveler is arranged between the fan section and the billet roller table, and is used to continuously pull out and straighten the arc billet. The tension straightener provides the straightening force for the billet. Thereby the billet is straightened from the arc state to the horizontal state. [0003] For profiled blanks, conventional tension leveling machines (such as figure 1 As shown), the upper roll 12 can only support the flange 22 of the special-shaped cast slab 20, and the outer roll surfaces of the upper roll 12 and the lower roll 13 are all equal-diameter structures, which cannot contact the web 21; The contact between the roller 12 , th...
