Suffered 'four put fire' the test of heat treatment of steel belt

Hardness and toughness of the strip to allow greater ascension, play to the role of the steel belt more, heat treatment process is necessary, heat treatment of steel strip after heat treatment can very good use for us, more show its role to, and the heat treatment process with the 'four' fire, normalizing, annealing, quenching and normalizing, the four put fire is in the process of heat treatment process need to experience the process of four below linyi Oriental steel strip co. , LTD. Will you chat with heat treatment process of the 'four fire'. The head of the heat treatment of steel belt fire, normalizing is steel strip after heated to a critical point, slow cooling, pearlite organization get treatment process; Annealing, steel belt, slow after heating to the appropriate temperature, stay time the steel strip to the slow cooling to the temperature of a process, annealing can be made by casting, forging, rolling, welding, and a series of steel strip after operation can improve the plasticity and toughness, remove residual force to get the expected physical properties. Annealing, of course, there are other purposes, the purpose of using annealing method vary; Quenching is brought in the steel after heating the inside of the steel strip steel austenite in body with proper cooling speed after cooling, the artifacts within the cross section within the prescribed scope of all or unstable structure such as martensite transformation of heat treatment process; Normalizing is very similar, and the effect of annealing steel strip is heated to the appropriate temperature and then place it slowly in the air for cooling, but compared with normalizing the organization more fine, commonly used to improve the cutting performance of material, is also sometimes used to some requirements are not high as end of heat treatment of parts. Above is the heat treatment of steel strip the 'four' fire, no fire collaboration between cooperate for heat treatment of steel strip production are indispensable, 'four fire' in each of the fire heating temperature and cooling in a different way, and will be developed different heat treatment process, but to produce steel strip quality is customer satisfaction. A: on the heat treatment of steel belt manufacturers take you know hot. 。 。 Next article: bluing steel strip surface quality requirements
