莱钢大型H型钢生产线高压水除鳞设备自投入生产以来,三种类型集水管配对三种钢坯规格的设计思想,由于设计缺陷而不能得到实现,集水管接头漏水严重,且锈蚀严重,除鳞效果较差,不能满足产品质量要求。对箱内上下三个集水管的排列方式进行改造后,实现了钢坯规格与集水管的匹配,解决了漏水问题,达到了理想的除鳞效果,提高了产品外观质量。
Since the design of high-pressure water descaling equipment of Laiwu Steel's large-scale H-beam production line has been put into production, the design specifications of the three types of water collecting pipes matching three kinds of billet specifications can not be realized due to design flaws, the water collecting fittings have serious water leakage and serious rusting, The effect is poor, can not meet the product quality requirements. After the transformation of the arrangement of the three water collecting pipes in the box, the specification of the steel slab is matched with the water collecting pipe, the water leakage problem is solved, the ideal descaling effect is achieved, and the appearance quality of the product is improved.
