Description

technical field

[0001] The invention relates to a cold rolling equipment, in particular to a strip steel stretching bending straightening machine roll set and a straightening machine thereof. technical background

[0002] In the cold-rolled sheet factory, the shape of the cold-rolled sheet is one of the key indicators of the quality of the steel sheet. With the development of science and technology, the requirements for the flatness of thin strip steel and ultra-thin strip steel are getting higher and higher. Steel plate straightening machines have experienced multi-roll straightening machines, tension straightening machines, and bending straightening machines. Among them, the bending straightening machine is widely used in units that require continuous stretching and bending straightening machines to solve the following problems of steel plates: eliminate the yield platform of the strip steel; improve the tensile strength and plastic deformation range; improve the flatness ...
