我厂生产290、CA一10等七种型号的内燃机曲轴、连杆、凸轮轴配件。材质全部为稀土镁球墨铸铁。原材料一直用本溪生铁。随着我国稀土镁球墨铸铁的迅速发展,本溪生铁已供不应求。遵照毛主席关于“备战、备荒、为人民”的伟大教导,为充分利用本省资源开辟途径,1971年初我们开始试用本省鄂城钢铁厂生铁(鄂铁),生产代40Cr钢高强度稀土镁球墨铸铁290曲轴。试验中,80%以上的曲轴铸态碳化
I plant 290, CA-10 and other seven types of internal combustion engine crankshaft, connecting rod, camshaft accessories. All materials for rare earth magnesium ductile iron. Benxi pig raw materials have been used. With the rapid development of China’s rare earth magnesium nodular cast iron, Benxi pig iron has been in short supply. In accordance with Chairman Mao’s great teaching on “preparing for war, preparing for waste and serving the people”, in order to make full use of the province’s resources, we started to pilot the pig iron (E-Rail) of Echeng Iron & Steel Plant in our province in early 1971 to produce 40Cr high strength rare earth magnesium nodular cast iron 290 crankshaft. In the test, more than 80% of crankshafts were cast as carbonized
