The surface of the steel strip processing

Metal decarburization will make the strip surface carbon content is reduced, thus an adult reduces the strip surface hardness, wear resistance and fatigue limit, for the spring steel, carbon tool steel and high carbon steel with the use of all is very bad. Obviously, strip oxidation and decarburization phenomenon in the heat treatment certificate by all don't want to exist. Therefore, to ensure the quality of strip steel heat treatment and avoid the strip surface oxidation and decarburization, must make furnace to produce more and complex gas does not react with strip. Bright heat treatment is to prevent the strip surface defects produced at high temperature of a - Kind of effective method. This method is with the help of the controlled atmosphere or material protection, prevent the strip surface oxidation decarbonization when heated, which remained light strip surface after heat treatment or basically no oxidation and decarburization.
