In the steel products market, buyers at sellers the service life of steel products is a very important factor. So what the service life of steel products and related, for instance, wire rope its service life of the rope depends mainly on its fatigue strength and wear resistance, if excessive decarburization on the surface of wire rope, will reduce as reinforcement and wear-resistant phase carbide in the surface layer, thus will directly affect the two performance. , such as tool steel, bearing steel, the surface of the decarburization layer if not clean, to make the tool steel, bearing steel surface hardness and wear resistance is reduced, and the quenching, due to the outer volume change in the different and the workpiece surface cracks. Can look for the degree of surface decarburization steel products will greatly influence the service life of it. So how to prevent the surface of the steel decarburization is should pay attention to the problems in the production process.
It is understood that foreign imports of the decarburization layer of the wire rod is 0.02 ~ 0.04 mm, of kobe wire rod surface can be done without decarburization, decarburization layer and the domestic like product average depth of more than 0.05 mm. So how to take measures to solve this problem?
Solve the problem of surface decarburization, key on the heat treatment process. Because the decarbonization and the oxidation of steel wire was conducted at the same time, therefore, as long as make less steel wire in the process of heat treatment is exposed to air can reach the purpose of improving the decarburization.
