In order to effectively improve the environmental problems caused by steel slag stacking, the air-quenching process of molten steel slag was carried out, and the properties of the air-quenched steel slag (AQSS) has been investigated by various characterization methods. The results show that the main phases of AQSS were Ca₂SiO₄, RO phase (solid solution formed by MgO, FeO, and MnO) and Ca₂Fe₂O₅. The AQSS met the technical requirements of a sandblasting abrasive. In addition, the Rockwell hardness of the AQSS with particle size of 1.0–3.0 mm exceeded 50.00 HRC. The particle size of 1–2.5 mm was particularly adapted to use as a sandblasting abrasive. It is clear that AQSS can be used as a sandblasting abrasive by analyzing and comparing the particle size and hardness of the AQSS and commonly used sandblasting abrasives.

为了有效改善钢渣堆放造成的环境问题，开展了钢水风淬工艺，并通过多种表征方法研究了风淬钢渣（AQSS）的性能。结果表明，AQS​​S的主要相为Ca ₂ SiO ₄、RO相（由MgO、FeO和MnO形成的固溶体）和Ca ₂ Fe ₂ O ₅. AQSS满足喷砂磨料的技术要求。此外，粒度为 1.0-3.0 mm 的 AQSS 的洛氏硬度超过 50.00 HRC。1-2.5 毫米的粒径特别适合用作喷砂磨料。通过对AQSS与常用喷​​砂磨料的粒度和硬度进行分析比较，可知AQSS可作为喷砂磨料使用。
