Black Round MS Seamless Pipe

Hot rolled seamless steel tube, as the name suggests, the rolling temperature is high, so the deformation resistance is small, can achieve a large amount of deformation.Taking the rolling of steel plate as an example, the thickness of continuous casting slab is generally about 230mm, but after rough rolling and finishing rolling, the final thickness is 1~20mm.At the same time, due to the small width to thickness ratio of steel plate, the size accuracy requirements are relatively low, not easy to appear plate shape problems, mainly to control the crown.For microstructure requirements, generally through the control rolling control cold to achieve, that is, to control the finishing rolling temperature, rolling temperature and curling temperature to control the strip microstructure and mechanical properties.
