The surface of the steel belt protection

In order to meet the demand of the market, steel belt manufacturer to heat treatment process for steel strip and cold treatment process, this can eliminate steel strip produced in the process of cold work hardening, help to regain the plastic property of the steel belt, continued cold rolling production; On the other hand can also guarantee the factory. In steel with heat treatment process is easy to cause the steel belt, particularly in the decarbonization of high carbon steel belt, the higher the temperature, the longer the time of heat preservation, decarburization tend to be more serious. And cold rolled steel with heat treatment the surface protection, can make the strip surface in the process of heat treatment do not produce the problem such as oxidation and decarburization, in order to reduce the strip cleaning and pickling process. So in the steel belt adopt the method of surface protection in heat treatment process can be very good avoid metal oxidation and decarburization, causes the metal loss, mechanical performance, reduce the service life and so on a series of problems.
