上钢三厂,过去冷修停留在60小时左右,是否还可提高,当时有两种的看法:一、认为场地面积小,没有加料起重设备;渣室体积小,不能使用大爆破,要缩短困难;二、要缩短有可能,必须肯定客观的条件,不盲目追求小型机械化,设法解决渣子房的积渣问题.5月中,在修炉前提出由64小时降至50小时(包括拆炉8小时,砌砖25小时,煤炉17小时),结果达到了47°29′的冷修新纪录(包括拆炉9°40′砌炉 20°49′,木柴烘炉8°38′,煤气烘炉8°22′).(1)计划进度及调度方面:
On the steel plant, in the past cold repair stay in about 60 hours, whether it can be improved, there were two views: First, that the venue area is small, there is no lifting equipment; slag room is small, can not use the big blast, to Shorten the difficulty; Second, to shorten the possibility, we must affirm the objective conditions, do not blindly pursue the small mechanization, trying to solve the slag residue slag room problem .In May, before repair furnace proposed by 64 hours to 50 hours (including the demolition Furnace 8 hours, brick 25 hours, coal stove 17 hours), the result reached 47 ° 29 ’record of cold repair (including demolition 9 ° 40’ furnace 20 ° 49 ’, wood oven 8 ° 38’ Gas oven 8 ° 22 ’) (1) Planning progress and scheduling:
