摘　　要：This study focuses on the development of a new type of nonmetallic steelmaking slag abrasive. The performance ,processing, and application of steelmaking slag as a nonmetallic abrasive are introduced. The chemical composition, hardness, crushing value, and particle gradation of steelmaking slag are analyzed. A processing method for steelmaking slag as a blasting abrasive is suggested and evaluated. Compared with conventional abrasives such as copper ore sand and cast iron shot, processed steelmaking slag exhibits similar performance and can satisfy abrasive technical requirements. The derusting effect provided by steelmaking slag for a ship deck can reach the Sa2.0 level, and its recyclability is higher than that of copper ore sand. The derusting performance of steelmaking slag is similar to that of copper ore, and it can thus be used in repairing ship decks.This study focuses on the development of a new type of nonmetallic steelmaking slag abrasive.
