Heat treatment effect of high temperature vacuum furnace

Choosing suitable sintering atmosphere for different materials is helpful to the sintering process, the densification degree of products and the products with good properties

Classification of Quenchants for heat treatment in high temperature vacuum furnace

Liquid: water, inorganic solution, organic polymer solution, quenching oil, molten metal, molten salt, molten alkali

Gas: air, compressed air, liquefied gas

Solid: flow bed, metal plate

Among them, water, inorganic aqueous solution, organic polymer aqueous solution, various quenching oils, etc. change in the state of matter under vacuum, while gas, molten metal, molten salt, molten alkali, metal plate do not change in the state of matter during quenching.

Heat treatment effect of high temperature vacuum furnace

The surface hardness of workpieces treated in high temperature vacuum furnace is uniform enough to eliminate quenching cracks and reduce quenching deformation. Therefore, the cooling speed of the workpiece immersed in the quenching medium in the high temperature vacuum furnace is as slow as possible to reduce the thermal stress and structural stress caused by the temperature difference between the inside and outside of the workpiece, so as to effectively prevent the deformation and cracking of the workpiece. GWL is ideal for fast cooling in high temperature stage and slow cooling in low temperature stage.

Quenching heat treatment in high temperature vacuum atmosphere furnace can avoid deformation and cracking of workpieces. After quenching, the surface of workpieces shall be kept clean. Even if there is adhesive, it is easy to clean and do not corrode workpieces. In the process of use, it has stable performance, no decomposition, no deterioration, no aging, easy to control, easy to prepare, transport and store, and safe to use.
