Weather resistant steel is a steel series that can be used in thinner, exposed, or simplified coating, so as to extend the life of products, save labor and reduce consumption, and upgrade. It is also a steel series that can be integrated into modern metallurgical new mechanisms, new technologies, and new processes.
Weather resistant steel generally adopts the process route of refined material entering the furnace-smelting 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. By adding rare earth elements to the steel, the weather resistant steel is purified and the content of inclusions is greatly reduced.
