Vacuum professional mesh belt furnace technology is a new type of professional mesh belt furnace technology developed in recent years. It has the characteristics that are urgently needed in mold manufacturing, such as preventing heating oxidation and non decarburization, vacuum degassing or degassing, eliminating hydrogen embrittlement, so as to improve the plasticity, toughness and fatigue strength of materials (parts). Slow vacuum heating, small temperature difference between inside and outside of parts and other factors determine the small deformation of parts caused by vacuum professional mesh belt furnace process.
The successful development and application of computer simulation technology in the process of professional mesh belt furnace make it possible for the intelligent professional mesh belt furnace of mould. Due to the characteristics of small batch (even single piece) and multiple varieties of mold production, as well as the characteristics of high performance requirements for professional mesh belt furnace and no waste products, the intelligent professional mesh belt furnace of mold has become a must. In foreign developed countries, such as the United States, Japan and so on, the development of vacuum high-pressure gas quenching is very fast, the main target is also mold.
The main application of mesh belt furnace in mould vacuum specialty is vacuum oil cooling quenching, vacuum air cooling quenching and vacuum tempering. In order to maintain the excellent characteristics of workpiece (such as mold) vacuum heating, the selection and formulation of coolant and cooling process are very important. For the working surface of the mould that is no longer machined after the professional mesh belt furnace, the vacuum tempering shall be used as much as possible after quenching, especially for the workpiece (mould) of vacuum quenching, which can improve the mechanical properties related to the surface quality, such as fatigue performance, surface brightness, corrosion resistance, etc.
