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2250mm热轧机和2130mm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.2250mm热轧薄板和2130mm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 preassembling 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.
