全国熔模精铸测试技术第二次协调会于82年4月14～18日在温州召开。会议由沈阳铸造研究所主持,有21个单位的32名代表参加。 与会代表首先回顾自1977年11月芜湖第一次会议以来的工作情况,认为四年内研制的四项型壳性能检测仪,对开发我国熔模铸造用新型制壳材料、研究制壳工艺和提高铸件质量等方面都起到了促进作用。 在此基础上,代表们进一步探讨了熔模铸造生产过程中,各个工艺环节所需要控制和测试的内容。 对于模料,认为应在“JZ—78—83—65”基础上及时予以修改和补充。建议采用热分析的方法研究模料的热稳定性、收缩和表面硬度。最好设计 National Investment Casting Test Technology second coordination meeting in April 82, April 18 to 18 held in Wenzhou. The conference was presided over by Shenyang Foundry Research Institute and attended by 32 representatives from 21 units. The delegates first reviewed the work done since the first meeting in Wuhu in November 1977 and concluded that the four shell-type performance testers developed within four years are of great value to the development of new shell-making materials for investment casting in China, Casting quality and other aspects have played a catalytic role. On this basis, the delegates further discussed the contents of the control and testing required in each process during the investment casting process. For the mold, that should be “JZ-78-83-65” on the basis of timely amendments and additions. It is advisable to study the thermal stability, shrinkage and surface hardness of the mold by means of thermal analysis. Best design
