What is the material of hot rolled coil


hot-rolled plate is composed of hot-rolled steel, steel strip, which is also called "hot plate". In addition, the hot rolled steel in the hot rolled plate needs to have a width of more than 0.6m and a thickness of less than 0.2m, while the thickness of the hot rolled steel strip needs to be controlled within 1.2mm to 25mm. The use of


hot rolled plate is relatively extensive, and the effect is quite good, so what material is the hot rolled plate, now let's take a look. What is the material of

1. hot rolled plate?

hot rolled plate is composed of hot rolled steel and steel strip, which is also called "hot plate". In addition, the hot rolled steel in the hot rolled plate needs to have a width of more than 0.6m and a thickness of less than 0.2m, while the thickness of the hot rolled steel strip needs to be controlled within 1.2mm to 25mm. What are the advantages and disadvantages of

2. hot rolled plate

1, advantages of hot rolled plate: hot rolled plate can effectively deal with some defects, such as grain refinement in steel. In addition, the bubbles and cracks generated during pouring can be welded through high temperature treatment, thus avoiding the occurrence of such problems. Disadvantages of hot rolled plate: after hot rolled steel plate, the non-metallic substances existing in it will be pressed into thin sheets, resulting in delamination, and the quality will also be affected to a certain extent, bringing unnecessary trouble. What are the advantages and disadvantages of

3. cold rolled plate

, advantages of cold rolled plate: it can make steel produce greater deformation and improve the yield point of steel plate material. And the speed of molding is relatively fast, the output is also high, and the coating will not be damaged. Disadvantages of cold rolled plate: in the process of forming, there will be some stress in the cross-sectional position, resulting in certain changes in steel properties. Moreover, the wall thickness of the cold-rolled steel plate is relatively small, and the later processing will not increase the thickness, resulting in a weaker load acceptance capacity.
