Weathering Steel Manufacturing Process

Weathering steel generally adopts the process route of refined material entering the furnace-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, The scrap steel is added to the furnace along with the charge and smelted according to the conventional process. After tapping, the deoxidizer and alloy are added. After the molten steel is treated by argon blowing, it is cast immediately, and the molten steel after argon blowing and temperature adjustment is cast into a slab by a continuous casting machine. Rare earth elements are added to the steel, the weathering steel is purified, and the content of inclusions is greatly reduced
