和歌山原有4台小烧结机(2、3、4、5号机),它们的劳动生产率极低,且2号烧结机无余热回收系统,能耗相当高。更为严重的是设备陈旧,维修费用逐年升高。在目前要求生产率较低的情况下,采用将小烧结机更换为大型烧结机的做法是不明智的,最好的办法是充分发挥现有设备的能力。为此,于1985年3月25日至5月14日将4号机停机51天进行设备改造,改造的主要 The original Wakayama 4 small sintering machine (2, 3, 4, 5), their labor productivity is very low, and No. 2 sintering machine without waste heat recovery system, energy consumption is quite high. More serious is the outdated equipment, maintenance costs increased year by year. At a time when lower productivity is currently required, it is not wise to move from a small to a large sintering machine. The best way to do this is to give full play to the capabilities of existing equipment. To this end, March 25, 1985 to May 14, the No. 4 machine down 51 days for equipment modification, the transformation of the main
