一、前言容积在1000米~3以上的大型高炉检修,是一项较为复杂的工程,技术问题较多。如大小料钟定心,过去由于经验不多,在较长一段时间内,曾经成为许多难题中的难题。每次定心,都要从有关单位中抽调最有经验的工程师和施工队工人,组成小组进行攻关。但有时由于工期的限制,常不能顺利达到技术标准所规定的各项指标而勉强交工投产, First, the foreword Volume over 1000 meters ~ 3 large blast furnace overhaul, is a more complex project, more technical problems. Such as the size of the material center of the clock, the past due to lack of experience in the past, for a long period of time, has become a problem in many difficult problems. Each centering, we must deploy the most experienced engineers and construction team workers from the relevant units to form a team to tackle the problem. But sometimes due to the time limit, often can not successfully meet the technical standards set by the targets and barely put into operation,
