The simulations are done about variables, such as, stress, strain, the stretches between the stands, the size parameters of the steel tube, and the roll force parameters. According to its product catalogs the system can automatically divide the pass series, formulate the rolling table, and simulate the basic technological parameters in the stretch reducing process. All modules are integrated based on the developing environment of VB6. The system can draw simulation curves and pass pictures. Three kinds of database including the material database, pass design database, and product database are devised using Microsoft Access, which can be directly edited, corrected, and searched.展开更多
