返矿率和返矿平衡返矿率和返矿平衡return fines and it's balance  生产率上升;但当返矿率达到一定值时,继续增加返矿 率则烧结生产率下降。所以对烧结矿生产来说,有一个 最佳返矿率,它可以使生产率达到最高点。(图1)他的fankuangIO he fankuang pingheng研究还表明:当料层高度(H)一定时,烧结矿的机械强返矿率和返矿平衡(return fines andlt,s度随着燃料比(占矿石量的百分数)及返矿率(占混合balance)铁矿石烧结后因强度较差和未完全烧要…叫水的高湿度的细精矿等返矿率一般较高,可达40%一返矿率/o/o50%。混合料的混合和制粒不好、烧结机的布料不均、图1烧结生产率与返矿率及燃料比的关系烧结点火热量不足、烧结终点控制不好或未能烧透以及烧结矿卸出后的多次破碎及筛分等都会增加返矿料量的百分数)的增加而增加,但当返矿平衡时,返矿率。此外,当烧结制度(如料层高度、点火温度、燃料用率增加,配入混合料的矿石及燃料量必然减少,因而烧量、抽风负压等)与原料性质不相适应,或烧结作业失结矿的机械强度也随之下降。(图2)导致烧结生产过常未能及时调整时,返矿率也会升高。返矿中如含有大程不稳定的另一原因,是进入烧结混合料中的热返矿量未经烧结的烧结混合料,则返矿细粉多、含碳高、质量的波动引起烧结混合料中水、碳的波动,因而导致烧量差,对烧结过程有不利的影响。质量良好的返矿多数结矿的产量及质量的波动。采用热冲击秤或将热返矿是已烧结成矿但机械强度较差的粒状物料,其粒度一经冷却后送入配料室参加配料,可以解决此项问题。般应在smm以下。返矿平衡烧结生产过程得以进行的必要条件。 返矿对烧结过程的影响质量良好的返矿可改善烧结机投产后,需要经过较长时间才能达到返矿平衡混合料的粒度组成,提高料层的透气性,特别是在细精(B二1)。如果返矿槽的料位增加,即B>l时,则可增矿烧结时,返矿有利于细精矿制粒,从而提高细精矿的加混合料中的燃料量以获得强度较大的烧结矿,促进烧结生产率。质量好的返矿在烧结过程中易形成液相平衡;如果返矿槽料位下降,使槽内存料有被用尽的危可增加烧结过程的液相量,从而提高了烧结矿的机械险时,要降低配加的燃料量,使返矿量增加。如果较长强度。对于脉石难熔的难烧矿粉,返矿的作用更加显时间内未能达到返矿平衡,表明烧结过程的目标参数著。德国卡佩尔(F、caPPel)的研究表明:在燃料配比与操作参数之间的关系不相适应,则应调整操作参数。(占矿石量)一定、烧结矿的机械处理流程一定、且保持同理,在烧结杯试验中也必须遵循这个原则加果没有返矿平衡的条件下,提高返矿率(占混合料量),则烧结返矿平衡,很容易导致错误的结论。图3及图4示出返芝100厂,广一厂汽几汀茜二厂一下一下一犷门一 协90岁月,端乍脚碑共,卜叮号‘一斗,一书一+一州一川 姗一犷护了乳澎尹竺_。I卜义叼飞’.1’}}}】! 瑕n力.4岁尸,·。
