Magnesium-calcium environment-friendly stemming for submerged arc furnace and preparation method of magnesium-calcium environment-friendly stemming
The invention relates to magnesium-calcium environment-friendly stemming for a submerged arc furnace and a preparation method of the magnesium-calcium environment-friendly stemming. The stemming is prepared from the following raw materials in parts by weight: 40 to 70 parts of magnesium-calcium recycled material, 15 to 35 parts of titanium calcium aluminate fine powder, 5 to 15 parts of coke powder, 1 to 20 parts of white clay, 3 to 7 parts of high-temperature asphalt powder, 3 to 10 parts of additive micro powder and 4 to 30 parts of binding agent. According to the magnesium-calcium environment-friendly stemming for the submerged arc furnace, the magnesium-calcium recycled waste bricks serve as the main raw material for preparing the stemming, steel mill recycled waste refractory materials can be fully utilized, the resource utilization rate is high, environment friendliness is achieved, and the production cost is effectively reduced. Meanwhile, through reasonable matching with other components in the preparation raw materials, the use effect of the prepared magnesium-calcium environment-friendly stemming is equivalent to or even better than that of magnesium stemming, the tapping time is long, the high-temperature stability is good, blast furnace production and stable operation are completely met in the use process, and the cost is saved.
本申请涉及一种矿热炉用镁钙质环保炮泥及其制备方法。以制备原料的总重量份数计，所述炮泥的制备原料包括如下组分：40~70重量份的镁钙回收料、15~35重量份的钛铝酸钙细粉、5~15重量份的焦粉、1~20重量份的白粘土、3~7重量份的高温沥青粉、3~10重量份的添加剂微粉和4~30重量份的结合剂。本申请所述矿热炉用镁钙质环保炮泥以镁钙回收废砖作为制备所述炮泥的主原料，可以充分利用钢厂回收废旧耐材，资源利用率高，环境友好，且有效降低了生产成本。同时通过与制备原料中其他组分进行合理搭配，使得制备的镁钙质环保炮泥的使用效果与镁质炮泥相当甚至更好，出铁量时间长，高温稳定性好，使用过程中完全满足高炉生产与稳定运行而且节省成本。
