高炉炉前的渣、铁沟,每使用一周左右的时间就需要铺撒一层“沟泥”(混有一定比例沥青和粘土的焦粉)进行夯实。几十年来,这一直是高炉工人的一件繁重的体力劳动。这项工作中最累的要算夯实这道工序。材料铺撒在渣、铁沟内以后,由四个人抬着近百斤的重砣进行夯砸。用砣夯完,沟的两侧还要用铁锹拍打修整。这样,不但工人的体力消耗很大,且夯沟的时间很长。对出铁次数多的高炉来讲,由于相邻两次出铁时间间隔很短,这项工作的进行越发感到紧张。在轰轰烈烈的技术革新与技术革命运动中,鞍山钢铁学院师生与我厂生产工人一道,密切协作,怀着对减轻工人繁重体力劳动的阶级感情,针对这个难题进行了创造性的劳动,终于试制成功了电动船式炉前打夯机,实现了高炉炉前铺沟打夯的机械化。 Blast furnace slag, trenches, each using about a week or so need to spread a layer of “ditch mud” (mixed with a certain percentage of pitch and clay coke) to compaction. For decades, this has been a heavy manual labor for blast furnace workers. The most tired of this work to be compacted this process. Spread material in the slag, trenches later, carried by nearly four hundred people a hundred pounds of heavy rammed smashed. With ram finish, ditch on both sides but also with a shovel patching. In this way, not only the workers’ physical exertion is very great, but also the time for ramming the ditches is long. For blast furnaces that have a lot of irons, the work is getting more and more tense due to the short time between two adjacent tapping operations. In the vigorous technical innovation and technological revolution movement, teachers and students from Anshan Iron and Steel Institute worked closely with the factory workers of our factory to carry out creative work on this difficult problem with the class feeling of alleviating the heavy manual labor of workers. Finally, the trial was successfully completed The electric boat-type ram front tamping machine to achieve the blast furnace front ditch ramming mechanization.
