return fines balance(【技】烧结过程产出的返矿量与烧结混合料中配人的返矿量相等时,叫返矿平衡。它是烧结生产过程得以进行的必要条件。烧结机投产后,需要经过较长时间才能达到返矿平衡 (B= 1)。如果返矿槽料位增加,即 B>1 时,则可增加混合料中的燃料量以获得强度大的烧结矿,促进平衡;如果返矿槽料位下降,使槽内存料有被用尽的危险,则要降低配加的燃料量,使返矿量增加。如果较长时间内未能达到返矿平衡,表明烧结过程的目标参数与操作参数之间的关系不适应,则应调整操作参数。: Return fines balance control by which the generation and consumption of return fines are kept constant in a narrow range by varying the addition of coke breeze. 采用返矿平衡控制,即通过改变焦末添加量使返矿的产出与消耗基本保持稳定。)
return fines set point(The return fines set point is chosen on the basis of process control consideration and remains at that level under steady operating conditions. 在对过程控制做出考量的基础上,选取返矿设定值,并在稳定的操作条件下保持该设定值不变。)
