八三年四月,在北京由兵器工业部新技术推广所主持召开了《弹尾零件挤压铸造技术鉴定会》。与会的有全国25个单位的近40名代表。 这项研究课题由内蒙金属材料研究所、国营华安机械厂共同承担。会上听取了有关“挤压铸造材料与工艺的总结”、生产试制和靶试总结报告。同时审查了研究工作总结、图纸资料及检测标准等技术文件。 In April 1983, he was chaired by the New Technology Promotion Office of the Ordnance Industry Department in Beijing to organize the “Stale Parts Squeeze Casting Technology Appraisal Meeting”. There were nearly 40 representatives from 25 organizations across the country. The research project was jointly undertaken by the Inner Mongolia Metal Materials Research Institute and the state-owned Huaan Machinery Plant. At the meeting, they heard a summary of “squeeze casting materials and processes”, production trials, and target test summary reports. At the same time, technical documents such as the summary of research work, drawing materials, and testing standards were reviewed.
