At present, the flat process of hot galvanizing units at home and abroad generally adopts the configuration mode of "light machine + pull straightening machine", one of the main functions of the light machine (most of the ordinary four-roll leveling machine) is to improve the mechanical properties and the surface of the light, and a certain improvement in the shape of the function, the pull straightening machine is mainly used to improve the shape of the plate. For the light machine:1. Flatten the strip surface, make the zinc layer better adhesion on the strip surface; 2. Control the shape, improve the product quality; 3. Improve the mechanical properties of the strip and eliminate the yielding platform;4. Pass the roughness, make the steel strip after finishing more easy to antirust treatment.Steel Coil
For the straightening machine:1. Good shape can be obtained. Through stretching and bending straightening, can completely eliminate the plate surface wave edge, wave shape, ladle curved and light sickle bend, thus, greatly improved the flatness of the sheet. 2. To improve the anisotropy of materials. The yield limit of the deep drawing sheet of low carbon steel in longitudinal and transverse often exists anisotropy. Therefore, in the thin plate for deep stamping processing, because the various parts of the extension of the different parts of the thickness will produce uneven, which will make the impact of the skirt lace defects, resulting in the increase in the rate of flushing waste. This condition is greatly improved by stretching and bending the straightening. 3. Eliminate the yield platform, prevent the formation of slip line!Steel Coil
Stainless steel tee originated in the 1980s, is a new industry. After $number years of pioneering and exploration, has now begun to take shape. Stainless Steel Tee is a kind of pipe fittings, mainly made of stainless steel material. With the development of the economy, the application of stainless steel tee is also more and more wide, the corrosion resistance of stainless steel surface passivation layer analysis, combined with advanced production technology and equipment applications, the production of stainless steel clamp, not only to meet the daily production and life needs, but also to fill the gaps in the country.Steel Coil
