唐山钢铁公司电炉炼钢厂改进传统的停电冷炉检修方法,创出了科学合理的筛选交叉检修作业法。经一年多的实践证明:采用此种方法检修时间由过去的6～8h,缩短到3～4h,仅此一项,全年可压缩检修时间252h,多产钢1224t。这种检修方法是把所有检修项目进行筛选 Tangshan Iron and Steel Company electric furnace steel mill to improve the traditional blackout overhaul method, creating a scientific and rational selection of cross-overhaul operation method. After more than a year of practice proved that using this method overhaul time from the past 6 ~ 8h, shortened to 3 ~ 4h, this alone, the whole year compressible overhaul time 252h, 1224t more steel. This maintenance method is to screen all the maintenance items
