description The invention relates to the technical field of metallurgy and solid waste comprehensive utilization, in particular to a method for improving the comprehensive utilization rate of steel slag, which comprises the following steps: S1, proportioning: compounding steel slag serving as a raw material with a hardening and tempering agent to obtain a compound; s2, smelting, wherein the compound obtained in the step S1 is put into a heating device to be smelted, and a mixture of liquid alloy and liquid reducing slag is obtained after an oxidation-reduction reaction; s3, separation is conducted, specifically, the mixture of the liquid alloy and the liquid reducing slag obtained in the step S2 is separated through the density difference of the liquid alloy and the liquid reducing slag; s4, the separated liquid alloy is cooled, and solid alloy is obtained; and the separated liquid-state reducing slag is rapidly cooled, and solid-state reducing slag is obtained. According to the method, metal resources and slag resources
