Production process of
A588 weathering steel plate: Weathering steel generally adopts fine material into furnace-smelting (converter, electric furnace, microalloying treatment, argon LF refining, low superheat continuous casting (feeding rare earth wire)-controlled rolling and cooling). During smelting, the scrap steel is added into the furnace with the charge, and is smelted according to the conventional process. After the steel is discharged, the deoxidizer and the alloy are added. After the molten steel is treated by argon blowing, the molten steel is immediately cast, and the molten steel after the argon temperature adjustment is cast by the continuous casting machine. As a slab, due to the addition of rare earth elements in the steel, the weathering steel is purified and the inclusion content is greatly reduced.
A588 weathering steel is widely used in outdoor steel such as container, power plant chimney and railway engineering, such as large outdoor sculpture steel. A588 weathering steel (ie, atmospheric corrosion resistant steel) is a low price between ordinary steel and stainless steel. The alloy steel series is one of the series of steel grades at the forefront of the world's super steel technology after being integrated into modern metallurgical new mechanisms, new technologies and new processes.
