高炉流铁沟是炼铁生产炉前重要设施,随着产量的提高,积极改善传统的流铁沟铺料,减轻炉前工人劳动强度,提高经济效益,国内外耐火材料工作者都在进行积极的探讨。鳞状石墨碳块是利用出铁时自动析出的石墨制成,它含C 28％,Fe 25％,FeO 26％,容重1t/m~3,呈松散状,具有良好的滑腻性,耐高温性,但过去一直作为废料被清除,既浪费人力,又污染环境。1982年9月以来,共进行了四个月三十余次的试制,试用,成功地制成了鳞状石墨碳块铺沟料。
Blast furnace tuggling is an important facility in front of ironmaking furnace. With the increase of output, the traditional iron trenches are actively improved, the labor intensity of furnaces is reduced, and the economic benefits are raised. Refractory workers both at home and abroad are active Discussion. Scaly graphite carbon block is made of graphite which is precipitated automatically when iron is used. It contains C 28%, Fe 25%, FeO 26% and bulk density 1t / m ~ 3, which is loose and has good smoothness, high temperature resistance However, in the past, it was removed as waste, which wastes manpower and pollutes the environment. Since September 1982, a total of four months more than thirty trial, a trial, successfully made of squamous graphite carbon block ditches.
