Background
Metallurgy is a process and technology for extracting metals or metal compounds from minerals and making metals into metal materials with certain properties by various processing methods, and after annealing, cold-rolled sheets often have poor plate shapes, for example, a wavy edge is formed when the edge extension of a strip steel is larger than the middle extension, a buckling is formed when the edge extension is smaller than the middle extension, and the buckling is adjusted by a withdrawal and straightening machine, which is also used in metallurgy operation.
The withdrawal and straightening machine is an important device of an arc-shaped billet continuous casting machine and has the functions of withdrawal and straightening of a casting blank. In all kinds of continuous casting machines, straightening machines are necessary, whereby the dummy bar and the strand solidified therewith are continuously drawn out of the casting mould and then passed through a secondary cooling support guide to the strand-drawing machine. After the casting blank is taken out of the pull roll, ingot can be removed, and the dummy bar is separated from the casting blank. In an actual arc continuous casting machine, two procedures of blank drawing and straightening are usually finished in the same machine set, so that the blank drawing and straightening machine is generally called as a drawing and straightening machine for short.
