Working principle of 1450 six-high rolling mill

Due to the high requirement of thickness tolerance of cold rolled strip, in order to improve the reaction speed of rolling mill screwdown device, the cold rolling mill adopts automatic control device of strip thickness of full hydraulic screwdown device to ensure the thickness tolerance of strip. For high speed and high quality strip cold rolling mill, computer control is realized. As one of the main actuators of modern AGC system, hydraulic transmission is used instead of mechanical transmission, which greatly improves the response speed and is the development direction of the screw-down device reform of cold tandem rolling mill.

Six-high rolling mill is one of the ideal advanced equipment for producing high-quality plate products at present, which can not only ensure high-quality plate and strip products, but also have obvious advantages in improving productivity, success rate and energy-saving effect, expanding application scope and improving the working performance of rolling mill. Domestic large six-high rolling mill has been successfully widely used in industrial production, and its technical level and function have reached the level of similar equipment abroad.
