Heat treatment of steel belt manufacturer production technology and matters needing attention

Heat treatment of steel strip can be seen everywhere in our life, architecture, hardware, bundling, packaging tapes and so on can see the figure of it, is that it is the strong body to give more sense of security, get the favour of more customers, also received the recognition from the society. Heat treatment of steel belt is from ordinary steel strip after heat treatment process to produce the new product, compared with other steel strip, steel strip has a great breakthrough on the performance of the heat treatment. General heat treatment of steel belt in the process of production is mainly divided into two main processes: annealing, quenching, and the rest of the heat treatment, annealing is the organization in deviating from the equilibrium state of the steel is heated to a certain degree, heat preservation and slow cooling in order to get a close to balance the organization's process; Quenching is above when heating temperature reached a tipping point, temperature austenitizing time, after the rapid cooling, martensitic transformation process, get to the organization and use of performance. Despite the heat treatment of steel belt in the process of production have very good performance, but because of some reasons, such as fatigue damage, the heat treatment of steel belt must have a high elastic limit and fatigue limit. In addition, still should have enough toughness and plasticity, in order to prevent suddenly brittle fracture under the action of a wallop. In the heat treatment of steel belt operation, need to pay attention to. Check whether there is surface decarburization before heat treatment, such as crack defects. 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 and cooling quenching cooling method. 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.
