徐州市科委受江苏省科委委托,于1983年12月25至27日,在徐州市召开了“熔模铸造减压吸铸试验研究”课题成果鉴定会。来自高等院校、科研、工厂31个单位的47名代表参加了会议。这一课题由江苏省徐州机械研究所承担,按课题要求,该所自行设计、制造了程序控制两工位吸铸机、该机完全满足减压吸铸工艺的要求。该所试验研究的熔模铸造减压吸铸工艺是成功的。它采用通用的水玻璃—铝矾土制壳
Xuzhou Science and Technology Commission commissioned by the Jiangsu Provincial Science and Technology Commission, held December 25, 1983 to December 27, held in Xuzhou City, “investment casting vacuum pressure drop casting experimental research,” the results appraisal meeting. Forty-seven representatives from 31 institutions of higher learning, scientific research and factories attended the meeting. This subject is undertaken by Xuzhou Institute of Machinery, Jiangsu Province. According to the requirements of the project, the institute designed and manufactured a two-station program-controlled suction-casting machine, which fully meets the requirements of vacuum-suction casting process. The experimental study of investment casting vacuum suction casting process is successful. It uses a common water glass - bauxite shell
