1.概况 1984年初,我厂无缝钢管车间进行了以增加产量、提高质量、扩大品种、降低消耗、改善环境为主要目的的技术改造,新建了φ90热轧无缝钢管机组,效果相当显著。在考虑φ90机组的轧管机机型时,决定先上自动轧管机,增上其他新型轧管机。因此在1985年4月10日与英国戴维·麦基(浦尔)公司正式签订引进改进型阿塞尔轧管机(即特朗斯瓦尔型轧机)的合同,1986年下半年
1. Introduction At the beginning of 1984, the seamless steel pipe workshop of our factory carried out technical renovation with the main purpose of increasing output, improving quality, expanding varieties, reducing consumption and improving the environment. The new φ90 hot-rolled seamless steel pipe unit has achieved remarkable results. In considering the φ90 unit of the pipe mill machine model, decided to first automatic pipe mill, adding other new pipe mill. Therefore, on April 10, 1985, it formally signed a contract with the British company David Mackie (Purcell) to introduce a modified Assel rolling mill (that is, the Trunswald rolling mill). In the second half of 1986
