攀成钢高炉无料钟布料规律研究
|
摘要
无料钟炉顶布料系统具有改善布料、提高煤气利用率等优势,在国内外的许多高炉上得到了广泛的运用。无料钟可以方便的调节炉料在炉喉内的分布、径向矿焦比,决定煤气流的分布、软融带的位置和形状以及滴落带的特征等等;而且炉料的分布对高炉的生产效率、能量的利用率和铁水的质量以及安全顺行和寿命都有很重要的作用。
为了在攀成钢无料钟高炉上更好的实现准确布料,改善煤气利用率,降低生铁成本,本文以四号高炉为研究对象,把生产中可能出现的参数代入无料钟布料方程,得到矿石和焦炭在不同参数下的堆尖位置,同时根据布料方程分别分析了料线、批重、界面效应、空区煤气阻力、溜槽摩擦系数、炉料粒度、溜槽转速等因素对布料的影响,得出了四号高炉有关料线、堆尖、批重对布料效果影响的十点结论。最后对多环布料和中心加焦产生的效果进行了简单的论述。
本文还在无料钟布料理论计算过程当中,根据攀成钢四号高炉长期使用的装料制度,通过大量的运算,得到了各煤气取样点的布料特征数,与2008年2-7月份的煤气平均成分进行了对比,得出二者之间存在一一对应关系,表明由布料方程计算的布料特征数具有实际生产指导意义。
Bell-less top charging system has the advantages of improving charging and enhancing gas utilization ratio and so on and has been used on many blast furnaces at home and broad. It easily adjusts burden distribution in furnace and ratio of ore to coke along the radial dirction and determines the distribution of gas, the position and shape of cohesive zone and the properties of the dropping zone. Burden distribution has important effect on the productive efficiency of blast furnace, energy utilization ratio, the quality of hot metal and the life and safe smooth operation.
In this paper, in order to exact charging, improving gas utilization ratio and reducing the cost of hot metal on NO. 4 blast furnace of Cheng Gang, the data from the blast furnace is putted into the equations of burden distribution. The heap positions of sinter and coke are obtained from the equations with different parameters. The paper studies the effects of the height of stockline, batch weight, interface effect, gas resistance, friction coefficient of chute, burden size and speed of chute on the charging. The ten results are about the height of stockline, batch weight and the heap position of burden profile. Finally, the mult-ring charging system and centeral coke charging are simply discussed.
The characteristic of gas sampling at 5 points is obtained from the quantity of calculations using the data from No.4 blast furnace with the help of theortical calculations. The characteristic is consistent with the average gas component of several months from February to July of 2008. This indicates the characteristic from the charging equations calculation has instructive effect on the actual blast furnace production.
