introduction：1.Beryllium oxide：Beryllium oxide doesnt just lose a lot of steel，It also reduces the surface quality of forging and the service life of forging die，If pressed into the metal，It will cause the forgings to be scrapped。Failure to remove beryllium oxide will affect machining。 2.decarburization：Decarbonization refers to the phenomenon that all or part of the carbon on the steel surface is burned off。Decarbonization causes soft spots on the surface of the workpiece，Reduces surface hardness、Wear resistance and fatigue strength。 3.Overheat and overburn：Superheat is when the steel exceeds the allowable temperature during heating，Make the grain grow coarse。Overheating is not conducive to heat treatment，The steel becomes brittle and the mechanical properties are reduced，However, it can be eliminated by normalizing or annealing after forging。Excessive burning refers to cause
