1984年元月14日北京市机械局铸造交流网在京召开铸件抛丸清理中推广应用钢粒(钢丝切粒)作为抛料的经验交流会,参加会议的有40多个单位、80余人。会上,北京重型机器厂铸钢车间介绍了车间在改用钢粒作为抛料以后,抛料寿命提高8倍以上,抛丸叶片寿命提高5倍以上,每年节约费用1万余元;北京市机电研究院金属强化室对钢粒、铸铁丸、铸钢丸和抛丸叶片在抛丸清理过程中的磨损情况及机理作了初步分析,北京钢粒厂也
On January 14, 1984, Beijing Machinery Bureau Casting Exchange Network convened an experience exchange seminar to popularize and apply steel pellets (wire pelletizing) as a throwing material in the blasting of castings in Beijing. More than 40 units and 80 people attended the meeting. At the meeting, Beijing Heavy Machinery Plant Steel Casting Workshop introduced the workshop to use steel particles as a throwing material, the throwing life expectancy increased by 8 times, throwing pill life more than 5 times, annual cost savings of more than 10,000 yuan; Beijing Mechanical and Electrical Research Institute of metal strengthening room of steel, cast iron, cast steel balls and shot blasting in the blasting process of abrasion and mechanism made a preliminary analysis of the Beijing steel plant also
