Everyone knows that H-beam is a long strip of steel with a cross-section of I-shaped. H-beam is a widely used steel that can now be used in bridges, building structures, vehicles, brackets, machinery and other fields.
Due to the complicated production process of H-beam, for example, in the process of production, quenching requires many different steps. Let H-beam manufacturer Yanxin Sen domain briefly introduce its quenching process.
H-beam quenching and cooling, the workpiece in the cooling process, the surface and the core cooling rate have a certain difference, if this difference is large enough, it is likely to cause more than the critical cooling rate to transform into martensite, if it is less than The critical cooling rate of the heart can not be transformed into martensite
Quenching and heat preservation, quenching and holding time are determined by various factors such as equipment heating method, part size, steel composition and equipment power. For the whole quenching, the main purpose of heat preservation is to make the internal temperature of the workpiece uniform and uniform, and to quench the H-shaped steel. The time ultimately depends on obtaining a good quenching heating structure in the area where quenching is required.
H-beam is a kind of steel with high efficiency and economical section shape. It can not only exert higher performance in the process of use, but also has high bearing capacity, so it is a profile that is popular among users.
