Shandong Shengya Machinery Co., Ltd. specializing in the production of various types of brick, brick machine, brick machine, hollow brick, pavement brick and other equipment of the old brick factory.
   Users buy cement brick or cement brick using all know, brick mold is the most important and easily damaged components, after a new tool in use for some time to reach a certain production needs to be replaced, all users hope more durable mold as possible, to avoid a lot of trouble, but also saves the mold changeover time, then what is mold carburizing handle it?
It is a kind of case-hardened surface hardening method, a chemical surface hardening methods. Carburizing, first produced in the surface of the carbon steel of the nascent, and then make it penetrate the surface layer of steel, and gradually spread into the interior of the nascent carbon is made by CO or CH4 and other gases from decomposition. CO sources of solid carburizing agent or by the reaction of which was generated in the carburizing of the container of the gas containing CO, or, or by a salt bath containing cyanide - get it. The nascent carbon from the surface of the steel of diffusion into the interior temperature of the steel that needs to be elevated into the stratosphere of austenitic range, so nascent ridge of carbon diffusion, 盖沃斯 field of iron more soluble and fat ferrite the solvency minimal, so carburizing temperature must be above the temperature Ac3. Carburization to be performed, together with various heat treatment method, so to generate a low hardness of the surface layer of steel high-carbon low-carbon hardened heart unit. The process for having a surface hardness and wear resistance, the center of the tough and impact-resistant properties.
