我厂广大革命职工遵照毛主席关于“自力更生,艰苦奋斗”的教导,在“鞍钢宪法”伟大红旗的指引下,大搞技术革新、技术革命,在冷挤压工艺的研究和使用方面作了一些工作,促进了生产的发展。我厂是生产高压电器产品的,铜零件占相当大的比重。这些零件一直采川铸坯、锻坯、元棒料进行切削加工而成。铸坯气孔砂眼多,导电性能差,废品极多,材料利用率仅有20%～50%,锻坯、元棒料的利用率也只有40%～60%,有大半的铜材变成了切屑。广大革命职工看在眼 Following the guidance of Chairman Mao on “self-reliance and hard work”, under the guidance of the great red banner of the Constitution of Anshan Iron and Steel, we made great efforts in technological innovation and technological revolution and made some research and application in cold extrusion process Work, and promote the development of production. Our factory is producing high-voltage electrical products, copper parts account for a large proportion. These parts have been mining Sichuan slab, forging billet, yuan bar for cutting. Billet stomatal many holes, poor conductivity, waste a lot of material utilization rate of only 20% to 50%, forging billets, yuan bar utilization is only 40% to 60%, more than half of the copper into a Chip. The majority of revolutionary workers are looking at the eye
