Abstract

Abstract

Using solid steel slag as raw material, steel slag with different particle sizes was prepared by air quenching after high-temperature remelting in an electric arc furnace. the differences and similarities of air-quenched steel slag with different particle sizes in terms of phase composition, microstructure, apparent density, morphological characteristics and hardness were compared, and the feasibility of using air-quenched steel slag as sandblasting abrasive was analyzed. The air-quenched steel slag with better abrasive properties was selected for sandblasting experiment. The results show that the phase composition of air-quenched steel slag is similar, mainly calcium silicate phase and cubic magnesite. The apparent density decreases with the increase of particle size, which conforms to the density standard of nonmetallic abrasives. The average Vickers hardness of the five particle sizes of air-quenched steel slag is more than 588, which is suitable for abrasive blasting. Considering the performance and blasting effect of different particle sizes of air-quenched steel slag, 0.5～1.0 mm air-quenched steel slag is the most suitable for abrasive blasting.
