to share here, I hope your Ete plate installation help, if you want to know more Ete plate knowledge, please continue to pay attention to every home decoration network.Cold-rolled sheet is processed on the basis of hot-rolled coil rolled out, after hot-pickling --- cold-rolled out, with low hardness, easy processing, good ductility, not easy to deformation and so on . Let's take a look at the advantages and disadvantages of hot rolled plate. First, the advantages of hot-rolled plate can damage the ingot casting organization, refine the grain of steel, and eliminate the defects of the microstructure, so that steel tissue dense, mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that steel to some extent is no longer isotropic body; pouring bubble formation, cracks and loose, but also under high temperature and pressure welded. Second, the shortcomings of hot-rolled plate After hot-rolled, steel non-metallic inclusions (mainly sulfides and oxides, there are silicate) is pressed into thin slices, there layer (sandwich) phenomenon. Stratification greatly deteriorates the properties of the steel in tension in the thickness direction and may cause interlayer tearing when the weld shrinks. The
