Gas-quenched steel slag abrasive was obtained by gas quenching with high-temperature liquid steel slag as raw material. The phase composition, thermal properties, micromorphology, magnetic properties, and mechanical properties of the particles were characterized by using an X-ray diffractometer, a differential thermal analyzer, a scanning electron microscope, a magnetic property meter, and a compressive strength tester, respectively. Results show that the gas-quenched steel slag abrasive is a monodisperse regular sphere. The compressive strength of a single particle is 34 N. The product is ferromagnetic and has good thermal properties. The micromorphology and flatness of the workpiece before and after grinding with the gas-quenched steel slag abrasive were measured using a three-dimensional profilometer. Results reveal that the surface roughness of the workpiece is reduced to 1.526, 0.623, and 0.227 µm after grinding for 5, 10, and 20 min, respectively. The surface profile fluctuation decreases to ± 1.0 µm. Thus, the workpiece surface tends to be flat without obvious scratches.

以高温液态钢渣为原料，通过气体淬火得到了气淬钢渣磨料。分别通过使用X射线衍射仪，差示热分析仪，扫描电子显微镜，磁性能仪和抗压强度测试仪来表征颗粒的相组成，热性能，微观形貌，磁性和机械性能。 。结果表明，气淬钢渣磨料为单分散规则球体。单个颗粒的抗压强度为34N。该产品具有铁磁性，并具有良好的热性能。使用三维轮廓仪测量在用气淬钢渣磨料研磨之前和之后的工件的微观形貌和平面度。结果显示，研磨5、10和20分钟后，工件的表面粗糙度分别降低到1.526、0.623和0.227 µm。表面轮廓波动减小到±1.0 µm。因此，工件表面趋于平坦而没有明显的划痕。
