Description

Technical Field

[0001] The utility model relates to the technical field of a straightening machine for a continuous casting machine, in particular to a straightening machine for a square or round billet continuous casting machine. Background Art

[0002] At present, the straightening machines used in large and medium-sized square and round billet continuous casting machines are mostly designed with multi-point straightening roller arrays. With the continuous improvement of domestic billet drawing speed and the rise of continuous straightening roller array technology, the requirements for the straightening machines of continuous casting machines are getting higher and higher. The original arch-type straightening machines have the phenomenon of deflection of the pressing roller during use, which makes it impossible to ensure the vertical pressing of the pressing roller, which has a certain impact on the quality of the billet, and can no longer meet the product quality requirements of the existing high-efficiency continuous casting machines. At the same time, since the straightening machines are used in the heat source concentrated area of ​​the continuous casting machine, and the current straightening machines generally have inadequate protection, it is impossible to provide comprehensive thermal radiation protection for the main equipment of the straightening machines, and there is a situation where the frame of the straightening machines is deformed after a period of use, which invisibly reduces the service life of the straightening machines. At the same time, with the deformation of the frame, the straightness of the upper roller of the existing arch-type straightening machines is getting worse and worse, which has a greater adverse effect on the quality of the generated billets.

[0003] A straightening machine of a square round billet continuous casting machine and a method for producing square round billets are disclosed in the Chinese utility model patent application publication specification CN 103464707 A.
