By definition, steel ingots or billets are difficult to deform at room temperature and are not easy to process. Generally, they are heated to 1100-1250°C for rolling. This rolling process is called hot rolling. The temperature of the hot-rolled sheet is high, so the deformation resistance is small, and a large amount of deformation can be achieved. Taking the rolling of steel plates as an example, the thickness of the continuous casting billet is generally about 230mm, and after rough rolling and finishing rolling, the final thickness is 1~20mm. At the same time, due to the small width-thickness ratio of the Plate Steel, the dimensional accuracy requirements are relatively low, and the shape problem is not prone to occur, and the main control is the convexity. For the requirements of the structure, it is generally achieved by controlled rolling and controlled cooling, that is, the opening temperature, final rolling temperature and coiling temperature of the finishing rolling are controlled to control the microstructure and mechanical properties of the strip. The Coating Galvanized Steel Strip Manufacturer will look at their types and uses together with you.
