铸造是一个大行业,在国民经济的各个方面铸件都得到广泛应用,因而在实现四化的征途上,广大铸造工作者不仅大有可为,而且应当多作贡献。摆在我们面前的总任务,是在稳定提高铸件质量、精度、光洁度的前提下,积极实现铸造生产过程的机械化自动化,节约能源,减少公害,降低成本。从表面上看,似乎这些都是“老生常谈”但不要忘记,这里所说的铸件质量、精度、光洁度等都是以现代化的水准为目标的。衡量的尺度是我们生产的铸件不仅 Casting is a big industry. Castings are widely used in all aspects of the national economy. Therefore, in the process of realizing the four modernizations, the majority of foundry workers are not only promising, but also making more contributions. The overall task before us is to actively mechanize the casting process, save energy, reduce pollution and reduce costs while steadily improving the quality, accuracy and finish of castings. On the surface, it seems that these are “clichés” but do not forget that casting quality, precision, finish, etc., are all aimed at modern standards. The measure of scale is not only the castings we produce
