摘要
本次改造根据铸管夹层打爆率较高,造成水压合格率低的问题,对铸管工艺、铁水成分两个方面进行改进。通过在铁水中加入废钢,加强对溜槽与管模之间的距离调整,管模改造等措施将夹层打爆管所占比率降为0.68%。
The transformation of a higher rate under the cast pipe sandwich Dabao, resulting in the problem of low pressure passing rate on the cast pipe technology to improve two aspects of hot metal composition. By adding molten iron scrap to enhance the chute and adjust the distance between the pipe mold, pipe mold reform and other measures will be laminated Dabao tube reduced the percentage of 0.68%.
