1. The presence of deformed steel carbide segregation and accumulation: Select the appropriate forging process. 2. Large-scale die selected low hardenability of steel: the correct selection of the appropriate forging steel. 3. Surface decarbonization or machine is not cleared off the surface decarburization process: Note forging heating protection standard, bath deoxygenation. The quenching temperature is too high forging sales, lack of heating time: strict control of the quenching process. 5. alkali bath water is too small: strict control of alkali bath water. 6. In the coolant residence time of less than: increased residence time. 7. tempering temperature: Select the appropriate tempering temperature. In search technology in recent years, also made a lot of new methods, such as global search, local search. Frictional contact force algorithm also has the penalty function method, Lagrange multiplier method child a variety of algorithms. Friction mechanism, many people designed a special device for the friction law metal forming under different conditions a lot of experiments, found that the actual situation and the Coulomb friction law and Coulomb's law significantly different proposed amendments described in subparagraph Methods.
