摘要
采用Ф500×500衄球磨机，磨制了比表面积为210～485m^2·kg^-1的慢冷转炉钢渣粉体，并对其粉体特性进行了研究．所测性能包括：安息角、自然堆积密度、粉体压缩特性和力学特性．研究结果表明：慢冷转炉钢渣粉体是一种粘聚性较低的典型库仑粉体，其粘聚性低于高炉矿渣粉体；随着比表面积的增大，慢冷转炉钢渣粉体的安息角随之增大，而自然堆积密度和压缩密度随之减小．当压力卸栽时，受压粉体表现出了一定的弹性性能．
The powder characteristics of the converter steel slag cooled naturally, with 210 - 485 m^2 ·kg^-1 Blaine specific surface area, have been studied by using a Ф 500 × 500 mm cement ball mill as grinding device in this paper. The powder characteristics measured in this study include stopping angle, natural packing density, condensability and mechanical properties. The experimental results indicate that the stopping angle is increasing with the specific surface area, whereas both the natural packing density and compressing density are decreasing with it. The steel slag powder is a typical coulomb powder, but with lower cohesion in comparison to the ground granulated blast - furnace slag. When the stress is removed, the compacted powder may exhibits a little elasticity.
