1) Cooling stage The purpose of slow cooling is to completely eliminate the residual stress. In the process of quenching and tempering, the residual stress will be produced in the metal matrix. During the transformation of retained austenite to martensite, the volume expansion will also increase the residual stress. Only slow cooling can offset the… Read more Significance of each stage of industrial cold treatment

Why to avoid corrosion when placing metal in cryogenic freezer
The ultra-low temperature freezing chamber is used for industrial cold treatment, which can freeze various copper sleeve, bearing and other materials. At the same time, attention should be paid to the corrosion of materials to avoid such corrosion. Therefore, metal corrosion is an electronic factor produced by anode and cathode connected by metal and electrolyte.… Read more Why to avoid corrosion when placing metal in cryogenic freezer
-80 ℃ cryogenic treatment – ultra low temperature cold assembly box maintenance
The maintenance method of cryogenic treatment is the same as that of industrial freezers such as kit freezer, kit freezer and metal freezer. Cryogenic treatment at – 80 ℃ is mainly used for industrial cold treatment. The precipitation of uniform, fine and dispersed carbonaceous materials produced on the metal structure matrix structure will significantly improve… Read more -80 ℃ cryogenic treatment – ultra low temperature cold assembly box maintenance
Cold Assembly Box
The assembly of cold assembly box is a kind of assembly method which uses refrigeration medium to cool the parts which need to be put into the base hole first, so as to reduce the overall size of the parts, so as to produce the assembly gap, so as to facilitate the easy assembly of… Read more Cold Assembly Box
