本文提出了一种用钢筋耐火混凝土模具替代传统的金属模具超塑成形金属板件的工艺。用这种工艺成功地成形出了长轴为1834mm、短轴为1500mm的LF3(M)铝合金卫星接收天线抛物面。这种替代为降低模具加工难度、节约金属模具材料、减少能源消耗、提高企业效益开辟了一条新的途径。

A technology for the superplastic forming of metal sheets with the refractory concrete die is put forward in this paper. The fact that the paraboloid components with a major axis of 1834 mm and a minor axis of 1500mm, which are used for satellite receiving antennas, have been auceessfully formed by using the refractory concrete die gives full supput to the conclusion that in the superplastic forming of metal sheets, the refractory concrete die can replace that of metal to reduce the difficulties in manufacturing the forming die and to save the expensive metal material as well as to cut down the heating power consumption, that is, to increase the company benefits.
