竖罐炼锌对蒸馏炉料——团矿的质量有严格的要求,即要求机械强度高(赤热状态下)、气孔率高、锌品位高、还原性好和焦结后的温度高。团矿质量的好坏是影响竖罐炼锌技术经济指标的主要因素。团矿主要是由焙砂及炭质还原剂所组成,炭质还原剂的合理选择与使用,对获得质地优良的团矿有着十分重要的作用。 Vertical tank zinc smelting distillation of the material - the quality of the group of mines have strict requirements that require high mechanical strength (red hot state), high porosity, high zinc grade, good reducibility and coke after the high temperature. The quality of the mines is the main factor that affects the technical and economic indexes of vertical zinc smelting. The mines are mainly composed of calcine and carbonaceous reductants. The rational selection and use of carbonaceous reductants play a very important role in obtaining high-quality mines.
