Q355nh Weathering Steel Plate|0.28mm Thick Weathering Steel
Principle of weather-resistant steel
The addition of phosphorus, copper, chromium, nickel and other trace elements to the steel surface to form a dense and strong adhesion of the protective film to prevent the spread and development of rust in the rust layer to protect the substrate below the rust layer to slow down its corrosion rate. In the rust layer and the substrate formed between about 50μm ~ 100μm thick amorphous spinel-type oxide layer dense and good adhesion with the base metal, due to the existence of this layer of dense oxide film, prevented the atmospheric oxygen and water to the steel substrate penetration, slowed the corrosion to the steel material deep development, greatly improving the ability of steel materials to resist atmospheric corrosion. Weathering steel can be used thin, bare or simplified coating, and make the products corrosion-resistant life extension, labor saving, upgrading the steel system, but also a modern metallurgy can be integrated into the new mechanism, new technology, new technology and make its continuous development and innovation of the steel system.
Weathering steel manufacturing process
Weathering steel generally adopts the process route of fine material into the furnace - smelting (converter, electric furnace - micro-alloy treatment - argon blowing - LF refining - low superheat continuous casting (feeding rare earth wire) - controlled rolling and controlled cooling. In smelting, scrap is added to the furnace with the furnace charge, smelted according to the conventional process, deoxidizer and alloy are added after the steel is discharged, the steel is treated with argon blowing, followed by casting, and the steel is cast into slabs by continuous casting machine after the argon blowing and temperature adjustment. Due to the addition of rare earth elements in the steel, the weathering steel is purified and the content of inclusions is greatly reduced.
