Advanced S6-high technology for cold rolling.The endless strip production process avoids the threading of the new coil in the finishing mill, so the thin (0.8-1.0 mm) coil can be produced safely and reliably. It is estimated that the yield of steel from molten steel to coil can reach 98.0% 98.5%, while ISP process is only 96.5%; ④ It can produce high-quality ultra-thin strip steelRolling Mill Production Line: Endless Continuous Casting and Rolling

The scientific rolling schedule is the fundamental guarantee for the production capacity of the rolling mill, product quality, accuracy, shape quality, energy saving, and consumption reduction. This paper takes the dynamic rolling process of single-stand cold rolling as the research object, the purposes of increasing production capacity, savingThe present investigation devices a novel X-type six-high (X-6h) mill. In addition, parametric models of different roll layouts such as the four-high (4-h), I-type six-high (I-6h), and X-6h mills are established. Three-dimensional (3D) finite element (FE) contact analysis for a strip rolling process is conducted when the mills are subjected to a Optimization design of a novel X-type six-high rolling mill

(2012) analyzed the cause and characteristics of the chatter vibration in a six-high cold rolling mill by using multibody dynamics. However, it is difficult to incorporate coupling effects and interactions between stands in FEM model. Based on state-space methods, Hu et al.
