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. At high temperatures, iron and steel in the furnace gas in the oxy-form FeO ﹑ ﹑ Fe3O4 and Fe2O3 oxides, known as scale. Scale generation increases the wear of the metal. Oxidation typically intermittent flame furnace burning rate of 2 to 3%, less than 0.5% the induction heating. In addition, the scale will exacerbate mold wear, reducing the precision forgings and lead to surface roughness, thereby increasing the machining allowance, increased material consumption.
