Abstract

The present invention relates to slag balls for an abrasive material, and a facility end method for manufacturing the same. More specifically, the present invention relates to slag balls which can be utilized as an abrasive material for blast cleaning and are prepared by atomizing waste steel-making slag (converter slag or electric furnace slag) remaining after steel-making from steel making processes in iron mills. The above object can be accomplished by the provision of an abrasive material prepared by atomizing converter or electric furnace slag, and having a particle diameter of 0.1 to 2.0 mm and Mohs hardness of 6.5 to 8.0. The abrasive material prepared by special processing of melted steel-making slag in accordance with the present invention and manufacturing method thereof provide various advantages such as no need for a breaking step as needed in conventional methods using slag, high hardness, improved surface roughness of the workpiece to be abraded due to uniform particle size, easy recovery and re-usability due to magnetism, and remarkably reduced generation of dust.
