1422mm热轧线热卷箱开卷装置的改进

Improvement of decoiling Equipment of Hot Coiling-box on 1422mm Hot Strip Line

针对宝钢集团梅山钢铁有限公司热轧板厂1422mm机组热卷箱开卷装置在使用过程中存在的铲头油缸耳座螺栓易松动、开卷臂驱动盘螺栓易剪断、铲头铜套易磨损、液压部件和液压管路易泄露、开卷过程易堵钢等问题,通过改进开卷臂油缸耳座与底座配合尺寸、改变耳座螺栓固定形式、改进开卷程序、采用干油润滑开卷臂驱动马达的齿轮齿条、改进机体配管、改善铲头冷却状况和改进易松动部件的固定方式,明显降低了开卷装置的故障率,提高了开卷质量。

There were some problems of decoiling equipment of hot coiling-box on 1422mm hot strip line in Meisteel.The ear base bolts on shovel head cylinder were easily loosed,drive disk bolts on decoiling arm were easily sheared,copper sheathing was worn out easily,hydraulic assembly and pipe-line were easily leaked and the piece was blocked up easily while decoiling.The failure rate of decoiling equipment is decreased and the decoiling quality is improved by changing the size of the cylinder ear base and bottom base,ear base bolts fixation, decoiling program,and improving cooling condition of shovel head and the fixation of the assembly that easily loosed.
