This article Keywords: mold Vacuum Heat Treatment Technology
Vacuum heat treatment technology is developed in recent years a new type of heat treatment technology, it has the characteristics, it is urgently needed in mold manufacturing, such as to prevent oxidation and non-decarbonization heat, vacuum degassing or outgassing, eliminating hydrogen embrittlement, thereby enhancing material (parts) of the plasticity, toughness and fatigue strength. Vacuum heating is slow, spare parts a smaller temperature difference between inside and outside factors such as the decision of the vacuum heat treatment process caused by deformation of parts and small.
Mold vacuum heat treatment is the main application of the vacuum oil-cooling quenching, vacuum-cooled quenching and vacuum annealing. In order to maintain the workpiece (eg, mold) of the superior characteristics of vacuum heating, cooling agent and the cooling process of selection and development is very important, die quenching process is mainly used oil-cooling and air-cooled. For the heat treatment carried out after the machining of the mold is no longer face, vacuum annealing after quenching as far as possible, especially in the vacuum hardening of the workpiece (mold), which can improve the mechanical and surface quality-related properties, such as fatigue properties, surface brightness, corrosion resistance and so on.
