Metal stamping die after quenching cracks easily, the reason for mold scrapped due to: 1.
Die steel raw material have serious carbide segregation.
Forging process, such as forging heating temperature is too high, small deformation, slow stop forging temperature is high, the cooling speed after forging, etc. , make forging organization bulky and mesh, belt and chain carbide exists, the spheroidizing annealing is difficult to eliminate.
Spheroidizing annealing process, such as annealing temperature too high or too low, the isothermal annealing time is short, etc. , can result in uneven spheroidizing annealing organization or bad nodulizing.
Metal stamping die after quenching cracks easily, cause mould scrap solution: 1.
According to the die working conditions, production batch and toughness of the material itself performance, choose the metal stamping die steel with good quality.
Improve the forging process or use prepare normalizing heat treatment, to eliminate the raw material in the mesh and chain inhomogeneity of carbide and carbide.
Carbide segregation of to forging serious high carbon steel refine solid solution heat treatment can be performed.
After forging die blanks, formulate correct spheroidizing annealing process specification, tempering heat treatment can be used well and rapid spheroidizing annealing.
Reasonable furnace charging, ensure the mold billet in the furnace temperature uniformity.
