沙钢2#5m宽厚板生产线的热矫直工艺

Hot Straightening Technology for No.2 5m Broad Plank Production Line in Shagang

系统介绍了沙钢2#宽板生产线采用的全液压九辊强力热矫直机的原理、结构和工艺技术特点。强力矫直机中的L1、L2通讯与计算机模型控制、液压AGC辊缝调节、液压弯辊、整体倾动、倾斜、边辊自动调整等功能,确保了宽厚板产品能获得最佳的矫直平整度及最低的残余应力。

The article introduces the principle, structure and technical features of the hydraulic hot plate leveler with nine rollers in No.2 wide plate mill of Shagang, systematically. It is a strong leveler with the max torque of 40MN. The L1/L2 communication, leveling model controlled by PC, roll gap adjustment of hydraulic AGC, as well as the hydraulic roll bending, the roll cassettes tilting and skewing, and roll automatic adjustment of entry and exit, etc. had been applied in the designed leveler. It can make the wide plate products with perfect leveling flatness and minimum residual stress.
