Hot forging an important process before. After the metal is heated to a certain temperature to improve plasticity, degeneration resistance decreases. Carbonaceous temperature strength curve for 0.45% of carbon steel and nickel-chromium ﹑ ﹑ tungsten alloy. According to the curve shows that the metal as the temperature increase and strength. Forging billet heating temperature is typically heated to allow the metal before forging temperature. In order to ensure uniform temperature inside and outside, forging billet surface should be heated to the desired temperature after holding a certain time. Thermal conductivity of insulation and metal ﹑ time forging billet section size and placed in the furnace of the relevant state. Cold billet heating heating rate should not be too high to prevent between surface and core part of the temperature difference is too large and big heart Ministry of thermal stress. Heart Ministry prone to thermal stress cracking. Thermometer has a measure commonly used in the furnace thermocouples measure the surface temperature of the metal optical pyrometer. In terms of high-speed roller feeder search technology in recent years, 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.
