The production process of LR AH36 steel plate usually includes the following steps:
1. Raw material preparation: Select high-quality steel billets that meet the requirements as raw materials to ensure that the chemical composition and performance meet the technical requirements of LR AH36 steel plates.
2. Smelting: The steel billet is heated to the appropriate temperature, and then smelted through smelting equipment (such as converter, electric arc furnace, etc.), and the alloy composition and temperature are adjusted to obtain the required molten steel.
3. Continuous casting: Pour the melted molten steel into the continuous casting machine, and cool and solidify through the crystallizer to form the initial billet.
4. Hot rolling: After preheating, the billet is sent to the hot rolling mill for hot rolling processing. Through multi-pass rolling and temperature control, it is pressed into the primary form of LR AH36 steel plate.
5. Heat treatment: Heat treatment is performed on the hot-rolled LR AH36 steel plate, which usually includes normalizing treatment or controlled cooling to adjust the organizational structure and improve the mechanical properties of the steel plate.
6. Finishing: The heat-treated steel plate is subjected to surface cleaning, trimming, grinding and other finishing processes to ensure that the surface of the steel plate is flat and smooth.
7. Performance testing: Conduct chemical composition analysis, mechanical performance testing, metallographic structure analysis and other testing on the produced LR AH36 steel plates to ensure that the products meet standard requirements.
8. Packaging and storage: Pack the qualified LR AH36 steel plates, label them with relevant information, and store them properly until they are transported or used.
The above is the typical production process of LR AH36 steel plate. Each step requires strict control and inspection to ensure that the quality and performance of the final product meet the design requirements.
