柳钢炼铁厂高炉设备原来是按255m~3高炉配套设计的,设计利用系数为1.8～2.0t/(m~3·d)。随着高炉强化冶炼水平的提高,高炉各系统的设备能力明显不足,有的设备负荷太重,故障率太高。 1996年初,我们利用价值工程原理对现有设备进行了全面系统的分析研究,提出了一整套设备改造更新、大修的方案。通过努力,我们用较少的资金,完成了设备改造计划,使高炉设备满足年产生铁100万吨的生产需要。我们引入了价值工程原理对必须进行改造的高炉上料系统、出铁系统、送风系统、喷煤系
Liuzhou Iron and Steel Works blast furnace equipment was originally 255m ~ 3 blast furnace supporting design, design and utilization factor of 1.8 ~ 2.0t / (m ~ 3 · d). With the blast furnace to enhance the level of smelting, blast furnace system significantly less than the capacity of equipment, and some equipment load is too heavy, the failure rate is too high. In early 1996, we conducted a comprehensive and systematic analysis of the existing equipment by using the value engineering principle, and put forward a set of plans for retrofitting and overhauling the equipment. Through our efforts, we completed the equipment reconstruction plan with less capital, so that the blast furnace equipment can meet the production needs of producing 1 million tons of iron a year. We have introduced the principle of value engineering of blast furnace feeding system, tapping system, air supply system, coal injection system
