The present invention relates to a refining slag-forming agent, a preparation method and a smelting method applied to low-carbon steel wire rods. Waste slag and waste magnesium carbon bricks generated in the aluminum-killed steel refining process are used as main raw materials, which are mixed and crushed in a certain proportion to form a refining slag-forming agent that can be used for low-carbon steel wire rods and has anti-ladle erosion performance. The smelting method performs secondary deoxidation and modification on the refined slag through a reasonable feeding method, and designs a CaO-Al2O3-SiO2-MgO quaternary refining slag system with a high MgO content, which replaces the original CaO-SiO2 slag system. The present invention can not only meet the requirements of low-cost and pollution-free products, but also realize the metallurgical functions of refining rapid slag-forming, desulfurization and reducing the erosion of ladle refractory materials.
