A kind of production method of silicon deoxidized low-sulfur high-carbon steel
The invention relates to a production method for silicon deoxidation low-sulfur high-carbon steel. An electric furnace-LF-VD-continuous casting process is adopted. The production method comprises thesteps that 1, in the steel tapping process of an electric furnace, carbon powder is added firstly, then a silicon alloy and a manganese alloy are added for deoxidation alloying treatment, and then lime, calcium carbide, aluminum-free refining slag are added to conduct modification treatment on slag; 2, after an LF enters a station, reductive refining slag is made; 3, after it is determined that the sulfur content in molten steel is controlled to be under a target value, the content of all components in the molten steel is adjusted to be within the required high-carbon steel component range; and 4, the LF leaves the station after refining, VD and continuous casting processes are sequentially conducted, and the silicon deoxidation low-sulfur high-carbon steel is obtained. The production method is provided under the overall background of the molten-iron-free pretreatment desulfurization process in traditional smelting production of the silicon deoxidation low-sulfur high-carbon steel, thelimit of production of the silicon deoxidation low-sulfur high-carbon steel through the molten-iron-free pretreatment desulfurization process on equipment is overcome, in the LF refining process, therefining slag with the specific components and properties is smelted, and the dual purposes of efficient desulfurization of the molten steel and plastification control over inclusions are realized.
