TMCP process is an important means to improve the comprehensive properties of steel. It can be used to produce ship plate, vessel plate, boiler plate, bridge steel, etc. Compared with the normalized steel of the same strength grade, TMCP can reduce the alloy content of the NM500 anti wear steel plate steel, reduce the carbon equivalent and improve the welding performance. TMCP is more and more widely used in various types of steel rolling industry.
nm500 anti wear steel plate, wear resistant steel plate is more and more widely used. Some manufacturers make mass production, but the market is still in short supply, the prospect of wear resistant steel plate is very broad. In the production process of nm500 anti wear steel plate, wear-resistant steel plate, we must control the carbon content. For NM360 wear-resistant steel plate, its C content is 0.12%, which is longitudinal fracture. The probability of longitudinal fracture of steel with high content of S, P and Se is much higher than that of steel with manganese content of 0.7%.
After extrusion, the nm500 anti wear steel plate tube shall be removed for sizing. The sizing machine uses a cone-shaped bit to rotate into the steel embryo at high speed to drill holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter length of the drill bit of the sizing machine. After sizing, the steel pipe will enter the cooling tower and be cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection.
