大型板带轧机机架制造工艺研究

为实现大型轧机制造的国产化和降低轧机设备投资,结合马钢2 250 mm热轧机和2 130 mm冷轧机薄板生产线的特点和需要,对大型板带轧机机架的制造工艺进行了研究.经预装配测试,轧机机架的制造精度完全达标,各项性能指标完全符合设计的技术质量要求.2 250 mm热轧薄板和2 130 mm冷轧机薄生产线的工业试验结果表明:在确保轧机机架质量的前提下,降低了设备投资,缩短了制作时间.

Research on manufacturing technology of a large strip rolling mill stand

In order to realize domestic manufacture of a large rolling mill and reduce investment of equipment, the manufacture technology of a large strip rolling mill stand was studied considering the characteristics of a 2 250 mm hot rolling mill and a 2 130 mm cold rolling mill in Maanshan Iron and Steel Co. Ltd. Through pre-assembling and debugging, the manufacture precision and properties of the rolling mill stand met the demand. The results of industrial testing on 2 250 mm hot rolling sheets and 2 130 mm cold rolling sheets show that under the condition of ensuring the rolling mill's quality the investment of equipment reduces and the manufacture time shortens.
