Hot dip galvanized steel strip manufacturer for steel belt what matters need attention when the heat treatment process

Hot dip galvanized strip steel manufacturers in the production of heat treatment of steel strip will be used in the process of a kind of metal material, usually by heating and the metal materials and welding method, two or more metal material welding together, but in the welding in the process of the steel strip during heat treatment process and is easy to appear some problems, in order to avoid the happening of the problem, heat treatment of steel belt manufacturer in shandong in the process of production need to be pay attention to some things. Steel belt heat treatment before check whether there is surface defects such as decarburization and crack. These surface defects will seriously reduce the fatigue limit of spring; Quench heating should pay special attention to prevent overheating and decarburization, completes the salt bath deoxidization, control of furnace gas atmosphere, strictly control the heating temperature and time; In order to reduce the deformation, the spring in the heating furnace charging ways, jig form into cooling method and cooling quenching, As soon as possible after quenching tempering, heating to scoop. Tempering, quick cold can prevent the temper brittleness and compressive stress caused by surface, improve the fatigue strength. Linyi, of course, after the heat treatment of steel belt manufacturer in the process, also need to pay attention for post-processing, later processing can be divided into three points. 。 Passivation. Phosphating. With oil. This treatment can change the luster of the coating and the structure, that is why the zinc coating is the reason of corrosion, this process is also can increase its service life, also can achieve long-term don't fall off. Galvanized steel composition can ensure that this product is use for a long time, and performance is not reduced. A: on the necessary heat treatment of steel strip technique of choose and buy. 。 。 Next article: quenching steel belt manufacturer for steel strip becomes more toughness
