摘　　要：本文对不同厂家生产的钢丸密度、硬度、粒度分布、金相组织和寿命进行分析,优选了一种使用寿命长的钢丸应用于生产。通过试验找到了钢丸粒度、抛丸速度和表面粗糙度之间的关系,并分析了生产过程中钢丸粒度的变化和补充加料方式对清理效率和铸件表面粗糙度的影响。Density,hardness,size distribution, microstructure and service life of steel shot produced by different plants have been analyzed and certain with long service life has been selected to be used in production. The relation among shot size, blasting speed and casting surface roughness has been found out via experiment and influence of variety of shot size and charging way on cleaning efficiency and casting surface roughness has been analysed.
