Generally speaking, 09CuPTiRE-A weathering steel adopts the process of fine charging smelting (converter, electric furnace microalloying treatment argon blowing LF refining low superheat continuous casting (feeding rare earth wire) - controlled rolling and controlled cooling. During smelting, scrap steel is added into the furnace together with the furnace charge, smelting is carried out according to the conventional process, Deoxidizer and alloy are added after tapping, the molten steel is treated by argon blowing, then casting is carried out, and the molten steel after argon blowing and temperature regulating is cast into slab by continuous casting machine. Due to the addition of rare earth elements in the steel, the 09CuPTiRE-A steel sheet is purified and the inclusion content is greatly reduced.
