简答题某高炉有效容积为417.5m3,风口中心线至零料线的容积为356m3,料线1.2m,炉喉直径4.2m,高度1.8m,每小时跑6批料,焦炭H=4.0,矿批重16t,原料配比为80%Z+20%T,求冶炼周期为多少?(注:堆比重Z:1.95t/m3,T:2.35t/m3,K:0.55t/m3,炉料压缩率0.92)
  • [356-π(4.2÷2)2×1.2] ÷[(16÷4÷0.55+0.8×16÷1.95+0.2×16÷2.35)×0.92]
    =(356-16.62)÷[(7.273+6.564+1.362)×0.92] =339.38÷[(15.199×0.92)=339.38÷13.983=24.3(批)
    则24.3÷6=4.05(小时)
