在技术革新中,技术人员深入现场,亲自动手,与工人密切配合,试验成功半干型铸造.现在我们车间的大、中型铸件都用此法铸造,这些铸件有壁厚达200公厘、高达500公厘、重达1吨的,解决了过去干型铸造多所造成的烘炉不够,砂箱周转不过来的部题,同时降低了铸件的成本. In technical innovation, technicians went to the scene, hands-on, working closely with the workers to successfully test semi-dry castings. Now, large and medium-sized castings of our workshop are cast by this method. These castings have wall thickness of 200 mm, 500 mm, weighing 1 ton, to solve the dry cast more than the past caused by the lack of ovens, sand box turn over problems, while reducing the cost of casting.
