Red rust steel plate production process

The red rust steel plate generally adopts the process route of fine feed into the furnace - smelting (converter, electric furnace - micro-alloying treatment - argon blowing -LF refining - low superheat continuous casting (feeding rare earth wire)- controlled rolling and controlled cooling. During the smelting process, the scrap steel is added to the furnace with the charge and smelted according to the conventional process. After the steel is produced, the deoxidizer and alloy are added. The molten steel is treated by argon blowing and then cast immediately. Due to the addition of rare earth elements in steel, the weather-resistant steel is purified and the content of inclusions is greatly reduced.

Weldability of resistant steel

If you use filler metal that is not resistant to atmospheric corrosion, you should ensure that the weld itself is weather-resistant. Prior to welding, the formed surface layer should be removed to a distance of 10mm to 20mm from the edge of the joint. Special precautions should be taken for welding steel grades S355J0WP and S355J2WP with high phosphorus content
