摘　　要：针对冲入法蠕化处理工艺在玻璃模具铸件应用中存在的技术问题,提出了“两步法”蠕化处理工艺,并介绍了其在玻璃模具铸件中的应用。生产实践证明,“两步法”蠕化处理工艺能够制备蠕化率稳定、收缩倾向小的蠕墨铸铁玻璃模具,显著提高了模具的使用寿命。Aiming at the technical problems existing in the application of sandwich method of vermicularising for glass mold castings, a “two-step” vermicularising treatment process was proposed, and its application in the glass mold castings was introduced. The practice proved that the “two-step” vermicularising method could stabilize the vermicular graphite rate and reduced the shrinkage defects of the glass mold castings. This new vermicularizing method could increase the life span of the glass mold remarkably.
