邢台钢铁厂有3座215m~3高炉和1座300m~3高炉,其铁水沟一直采用炭素料捣打。用该料制的沟内衬质量差,寿命短,且用人工捣打,工人劳动强度大。故此在300m~3高炉小铁沟上进行了新型沟料的试验,收到了较好的效果。新型沟料的配比为:矾土水泥1份,1～3mm骨料2份,3～6mm骨料1份,混匀后用水和成泥状。用新沟料做铁沟内衬时,不用电夯或人工捣打,只用铁锨将料放入沟内,用抹子抹成沟状光面,一股用煤气在沟表面上烘烤二三十分
Xingtai Iron and Steel Plant has 3 215m ~ 3 blast furnace and a 300m ~ 3 blast furnace, the iron ditch has been using carbon material ramming. The material made of the groove lining quality is poor, short life expectancy, and with manual ramming, workers labor intensity. Therefore, in the 300m ~ 3 blast furnace small iron ditch on a new type of test materials, received good results. The new ratio of ditch material: 1 cement, 1 ~ 3mm aggregate 2, 3 ~ 6mm aggregate 1, after mixing with water and clay. Do trenches with new ditch material, no electric ram or manual ramming, only the ferroalloy will be placed in the ditch, trowel with trowel smooth surface, a gas on the groove surface baking Twenty or thirty
