The physical description of the packaging steel strip cold rolling process

Packaging steel strip cold rolling process of the physical description of the roll gap part is divided into the following areas: ( 1) Elastic deformation area. On the lateral the entry and exit, there is only the elastic deformation of elastic deformation area. These areas with analytical method. ( 2) Plastic deformation zone. In the plastic deformation zone of material deformation is permanent. Stress numerical integration must be divided into two parts: the first slide area and smooth area. The two parts respectively from plastic deformation area boundary, to the end of the neutral point. Using numerical integration method to solve these regions because there is no known analytic method to solve the part deformation. More fully describes the deformation area ( Including elastic deformation and plastic deformation) The regional distribution and stress. The rolling pressure is elastic deformation and plastic deformation and part of the rolling force. Horizontal extrusion FQ, population and exports tension deformation area, population and exports in plastic deformation section rolling friction to plays a very important role in the solution, the mathematical model of kalman differential equations and its numerical integration method to solve the rolling force will do detailed force analysis of plastic deformation process.
