We all know that H-beam is a cross-section of a long steel I-shaped, H-beam is a very wide range of steel, can now be used in the field of bridges, building structures, vehicles, stents, machinery and so on.
Because of the H-beam production process is more complex, such as in the production process, quenching requires a lot of different steps, let the H-beam manufacturer flame Xin Sen domain for everyone briefly about its quenching process.
H-beam quenching, the workpiece in the cooling process, the cooling rate of the surface and the core portion of a certain difference, if this difference is large enough, it is likely to cause the cooling rate is greater than the critical part into martensite, if it is less than the critical cooling rate of the heart can not be converted into martensite
Quenching insulation, quenching insulation time heating equipment, parts size, steel composition and equipment power and other factors to determine the overall quenching, the main purpose of the insulation is to make uniform internal temperature of the workpiece, the H-beam quenching insulation time ultimately depends on the requirements of the quenching of the region to obtain good quenching heating organization
H-beam is an efficient and economical cross-sectional shape of the steel, in the course of use can not only play a higher performance, but also has a high carrying capacity, so it is a user favorite profile.
