3. Production process of SNCM815 bonded steel.
The production process of SNCM815 bonded steel mainly includes smelting, continuous casting, rolling and heat treatment. First of all, in the smelting process, an electric furnace or converter is used for primary smelting to remove impurities and harmful elements and improve the purity of the steel. Then, in the continuous casting process, the molten steel after the initial refining is injected into the continuous caster to form a billet of a certain specification. Then, in the rolling process, the continuously cast billet is rolled into the desired steel shape and size. Finally, in the heat treatment process, the rolled steel is heated, insulated and cooled to obtain the desired mechanical properties and corrosion resistance.
