[0002] Ultra-low temperature resistant cast steel of microalloying refers to the production process of cast steel, the performance of cast steel is improved by adding trace amounts of alloying elements, especially in the performance of ultra-low temperature environment. These microalloying elements can significantly improve the strength, toughness and corrosion resistance of cast steel, so that it can maintain good performance in extreme environment. The smelting equipment for the production of microalloyed ultra-low temperature resistant cast steel usually includes blast furnace, converter, refining furnace, continuous casting machine, etc. These devices can ensure that the molten steel is fully deoxidized, alloyed and accurately controlled in composition and temperature during smelting. In order to meet the high yield of microalloying elements, refining equipment such as LF furnace and RH vacuum degassing furnace is widely used. These devices can accurately adjust the composition of molten steel, improve the purity and performance of steel.
