Method for preparing lime for steelmaking and refining

The invention relates to a method for preparing lime for steelmaking and refining. The method comprises the following preparation steps: S1, selecting high-calcium limestone with qualified granularity; S2, treating the limestone by screening equipment and water washing to further improve the qualified rate and cleanness of the limestone; S3, quantitatively feeding the limestone into a kiln throughhoist lifting equipment, and carrying out calcining and decomposing; S4, introducing fuel gas into the kiln, and carrying out preheating, calcining and cooling on the limestone entering the kiln to generate high-quality lime; S5, discharging the lime from the bottom of the kiln, and conveying the lime to screening equipment for screening and grading; and S6, drying and storing the screened blockymaterials to obtain the high-quality lime for steelmaking and refining. The method can be used to solve the problem of lack of a method for preparing lime for steelmaking and refining by using limestone in the prior art. 本发明涉
