本文描述了印度比莱烧结厂当前条件下的返烧细粉制度及其影响因素。通过统计设计的罐式烧结实验，评价了返烧粉、碱度等变量对烧结矿产率和烧结速度的影响，建立了经验方程。已观察到对于线料生产率而言，碱度比和返回细粉输入的最佳水平。碱度比和焦粉含量是相互影响的：在较高碱度水平下进行烧结时，较多的焦粉量有助于提高生产率。混合物中大量的返回细粉（通过从高炉的烧结矿及其再循环中筛选出 -5 毫米尺寸的部分）会降低烧结线上新鲜材料的吞吐量。然而，部分损失可以通过烧结矿产量的同时增加得到补偿。
The paper describes return sinter fines regime and the factors influencing it under the prevailing condition of the sintering plant at Bhilai, India. The effect of return sinter fines, basicity and other variables on the yield of sinter and speed of sintering has been evaluated through the pot sintering experiments designed statistically and empirical equations have been established. An optimum level of basicity ratio and that of return fines input have been observed for the strand productivity. The basicity ratio and coke breeze content are inter-influenced: greater amount of coke breeze helps in productivity improvement when sintering is carried out at higher basicity lever. A greater amount of return fines in the mix (through screening out the -5 mm size fraction from the sinter at blast furnace and its recirculation) decreases the throughput of the fresh material on the sintering strand. However, part of loss is compensated by a simultaneous increase in the yield of sinter.
