由于钢产量迅速增长,对铸锭车架的需要是愈来愈多了。我们厂从试制到现在还不算久,但已经大批生产。在制造过程中,由于铸件结构复杂和经验不足,曾走了一段弯路。经过技术人员和工人同志们的努力,终于得出一个比较完善的工艺方案,避免了过去产量低、质量差的损失。 Due to the rapid growth of steel production, the need for ingot frames is growing. Our factory from trial to now is not too long, but has been mass-produced. In the manufacturing process, due to the complexity of the casting structure and lack of experience, had taken a detour. Through the efforts of technicians and workers, we finally came up with a relatively complete process plan to avoid the loss of low output and poor quality in the past.
