The technical requirements for rolling mill rolls mainly include the following points: firstly, the main equipment of the rolling mill is composed of a main engine train, which consists of three parts: the main motor, the rolling mill, and the transmission machinery. A rolling mill is generally composed of rolling mill, frame, adjusting device for rolling mill, balancing position of rolling mill, rolling mill bearings, etc. The function of the transmission device is to transmit the power of the electric motor to the rolling mill, and its composition is related to the type and working system of the rolling mill. Secondly, the material selection of the rolling mill is crucial. The extensive use of alloy elements was a result of the development of steel rolling equipment towards large-scale, continuous, high-speed, and automated production, as well as the improvement of rolling material strength and deformation resistance, which put forward higher requirements for the performance of the rolling mill after World War II. In addition, bending roll technology is also an important component of rolling mill roll technology, and hydraulic bending roll devices have become essential equipment on various plate and strip rolling mills.
