What is the production process of weather resistant steel?

Weather-resistant steel plates are made by adding phosphorus, nickel, copper and other trace elements to ordinary steel plates during the smelting process. A dense, highly protective film is formed on the surface of the steel, which prevents the further diffusion of rust, thereby protecting the underlying materials to slow down corrosion. The appearance of weathering steel plate is bare, and it can resist corrosion without using other coatings. It is environmentally friendly because it does not pollute the surrounding environment.

Weather resistant steel production process: Weathering steel is generally smelted into the furnace, including converter, electric furnace microalloying treatment, argon blowing refining, low superheat continuous casting, rare earth wire feeding, controlled rolling and controlled cooling. During smelting, scrap steel is added to the furnace along with the charge and smelted according to conventional methods. After the steel is discharged, add deoxidizer and alloy. After the molten steel is blown with argon, the steel is cast immediately, and the molten steel with the argon temperature adjusted by the continuous casting machine is poured. Due to the addition of rare earth elements in the steel, the weathered steel is purified and the inclusion content is greatly reduced.

With the rapid development of the national economy, the application of weather resistant steel has been brought together by relevant domestic departments. Paying attention to the development and upgrading of weathering steel plates is of high practical significance and has an important impact on the structural upgrading of the steel industry. The weather-resistant steel plate and strip produced by our company have passed material inspection and finished product inspection, and the quality is reliable.
