Comparison of the advantages of vacuum heat treatment and conventional heat treatment

Vacuum heat treatment is a new treatment technology combining vacuum technology and heat treatment technology, which can realize almost all the heat treatment processes involved in conventional heat treatment, and greatly improve the quality of heat treatment and the oxidation resistance and corrosion resistance of the workpiece. It can achieve no oxidation, no decarburization, no carburization, remove the phosphorus chips on the surface of the workpiece, and have the effect of degreasing and degassing, so as to achieve the effect of bright and purified surface.

Vacuum carburizing in one article

Vacuum carburizing is also a kind of carburizing, but the performance of the equipment is different, of course, the process is also very different. Vacuum carburizing is divided into vacuum carburizing oil quenching furnace and vacuum carburizing gas quenching furnace according to different quenching methods. From the appearance of the vacuum carburizing oil quenching furnace and vacuum oil quenching furnace similar, vacuum carburizing gas quenching furnace and vacuum high-pressure gas quenching furnace similar. After the addition of carburizing function, more gas supply system, gas flow control system, carburizing pressure control system and changes to the heating system, these system additions and changes, most of them are inside the equipment, so the appearance of the vacuum carburizing furnace and vacuum furnace is not very different.

Basic overview of carburization

Carburizing is the process of making carbon atoms infiltrate into the surface layer of steel. It is also the process of making a low carbon steel workpiece with the surface layer of high carbon steel, and then quenching and low temperature tempering to make the surface layer of the workpiece with high hardness and wear resistance, while the central part of the workpiece still maintains the toughness and plasticity of low carbon steel.

The vacuum furnace designed from the process perspective will make a good product

The popularity of vacuum furnace is in the background of this era came into being. Vacuum furnace in the parts heat treatment in a vacuum state, completely avoiding the problem of oxidation, vacuum heat treatment of parts after the performance is more stable and reliable, to provide a guarantee for precision workpiece processing. According to statistics, the service life of parts treated with vacuum furnaces is 30% or even several times higher than that of parts treated by ordinary processes with comparable hardness.
