球墨铸铁材料具有较高的机械强度和优良的铸造性能。汽车和发动机中的某些零部件,实行以铸代锻、以铁代钢可以节省钢材、缩短生产周期、降低生产成本。实行以铸代锻,对大型企业来说,可以解放出部分通用设备和专用设备,为扩大再生产创造有利条件;对发展地方中、小企业来说,则投资少、上马快,更有很大的促进作用。这对于贯彻毛主席“备战、备荒、为人民”的伟大战略方针是很有意义的。
Ductile iron material with high mechanical strength and excellent casting performance. Some parts of the car and engine, the implementation of casting forging, to replace the iron steel can save steel, shorten the production cycle and reduce production costs. The implementation of the forging forging, for large enterprises, you can liberate some of the common equipment and special equipment, to create favorable conditions for the expansion of reproduction; for the development of local small and medium enterprises, the less investment, launched fast, more significant The promotion effect. This is of great significance to implementing Chairman Mao’s great strategic principle of “preparing for war, preparing for war and for the people.”
