What is the processing technology of hot rolled steel plate?
Hot-rolled steel plate processing technology is an important metal processing technology used to produce various steel plates and steel products, which are widely used in automobile manufacturing, shipbuilding, bridge construction, building structures and other industrial fields.
1. Raw material preparation: The raw material of hot-rolled steel plate is steel billet. First, the steel billet needs to be cleaned and derusted to ensure a smooth surface and cut into appropriate sizes.
2. Hot rolling processing: Steel billet needs to be preheated to improve processing performance and reduce energy consumption. Usually, the steel billet is put into the heating furnace for preheating, and the next step is entered after reaching a certain temperature.
3. Rolling: The preheated steel billet is sent to the rolling mill for rolling, and the steel billet is processed into the required plate thickness and shape through a series of processes. During the rolling process, the position and pressure of the rollers need to be continuously adjusted to ensure the size and surface quality of the plate.
4. Cooling: The rolled steel plate needs to be cooled quickly to reduce grain growth and improve mechanical properties. Usually water cooling or air cooling is used.
5. Leveling: The cooled steel plate may have a certain degree of deformation and unevenness, and needs to be leveled, and the surface of the steel plate can be made smooth through a pressure roller or grinding process.
6. Cut to length: The flattened steel plate needs to be cut according to the size required by the customer to obtain the final product.
The hot-rolled steel plate processing technology is a complex system engineering that requires strict control of parameters such as rolling temperature, rolling intensity, and rolling speed to ensure the forming quality and performance of the steel plate.
