But the material section is forged and processed and circulated due to abnormal heating temperature (caused by insufficient temperature or overhigh temperature to cause overburning) of the forging raw material caused by personnel fatigue and working negligence in the production process. The product is scrapped due to the fact that the subsequent forging forming cannot be filled when the temperature of the material section is too low, over-burning is formed due to the fact that the temperature of the material section is too high, grains are thick after the over-burning, grain boundaries are melted (the grain boundaries are seriously oxidized and low-melting-point components are melted, the mutual connection among the grains is damaged), oxides are formed, and cracks are prone to occurring. In the process of heating, sparks are emitted from steel in a forging factory, and the phenomenon of melting or oxidation along a grain boundary is observed, so that the strength is extremely low, and the steel cannot be used. The burnt piece can not be remedied and can only be discarded. Over-burning is an unallowable defect of heat treatment, so that the over-burning of the forging is strictly prevented in the heat treatment production. The low temperature and high temperature-overburning of the raw material of the forging are caused by the insufficient control of the heating temperature.
