我厂炼铜转炉内衬系采用铬镁砖,作为制砖原料的铬矿,大多靠从国外进口,而我厂转炉炉龄较短,耐火材料消耗量很大,每次修炉都有大量废砖丢弃,既造成巨大的浪费,又影响环境卫生。自1970午以来,我厂修炉工人积极开展了转炉废砖的回收利用工作,他们不仅将大块废砖采用人工加工成型,重新砌入炉内使用,而且整修了一台小球磨,将小块的废砖磨成粉,作为调制灰浆的原料。1970年以来,共磨出镁砂粉1600吨以上,使我厂砌炉灰浆镁粉做到自给,为国家节约资金近32万元。
I plant copper converter lining with chromium magnesia brick, chrome ore as a brick raw material, mostly imported from abroad, and I plant a shorter furnace age, refractory material consumption is large, each repair furnace has a large number of Disposal of waste bricks not only results in huge waste but also impacts on sanitation. Since 1970, our factory repair furnace workers actively carry out the recycling of waste brick, they not only large blocks of waste brick by manual processing, re-use into the furnace, and the renovation of a small ball mill, the small Block waste brick crushed into powder, as a raw material for modulation mortar. Since 1970, a total of more than 1,600 tons of magnesia powder grinding, so I plant mortar magnesium powder to make self-sufficiency, saving nearly 320,000 yuan for the country.
