厚料层烧结厚料层烧结sintering with high beddepthhouliaoeeng shaojie厚料层烧结(sintering withhigh beddepth)在烧结炉算上，保持较高的铺料厚度进行烧结的铁矿石烧结工艺。这种工艺能有效地改善烧结矿的质量:提高烧结矿机械强度、减少粉末量、降低氧化亚铁(FeO)含量、改善还原性能。此外，对提高烧结矿成品率和节约燃料消耗也都有显著的效果。基本原理充分利用烧结过程自动蓄热的特点达 ，阵大冲今 “迪竺二 时间图l烧结过程中料层温度的变化 (t1~t4为上、中、下及底层的温度变化)到上述效果。当烧结混合料层表面点火并抽入空气后，烧结过程中的燃烧带从烧结开始沿料层高度逐渐往下进行，从而形成烧结矿带、燃烧带、预热带、干燥带和过湿带五个层次。图1为烧结过程中沿料层高度上各点的温度分布。图中示出烧结过程中料层温度呈现由上往下逐步升高的趋势，这一现象主要是由于烧结过程的自动蓄热作用。前苏联西哥夫(A.A.C、oB)曾经对烧结过程的蓄热作用进行定量研究，将正常配碳的混合料层按等高分割成薄层小单元，按单位面积计算每单元的热平衡，位于下面单元的热收入比位于其上的单元增加了两部分热量，即从上层热矿冷却过程带入的热量和上层反应热废气带入的热量。图2示出通过 尹〔二二二二二二二口三三二二二二二，。3卜一一‘一-一一一一月一—一一一一-二、，(，一‘一一‘、尺一-一11尺dJ〔二二二二二二二二习二二二二二二二二立5夏二二二五二二{益’扭卜一了-汁一一万一二、守州尝6卜一一一一乙一一一一一一卜一一一宾，U厂一一一一一一一一r一一一一一一81…，j…，，.…伙}1 2 3 45 6 7891011121314热量/x4.186.8k」图2沿料层高度各单元热量的变化1一燃料燃烧热量;2一废气及预热 空气的热(蓄热);3一点火供热测定与计算得出的料层各单元热量变化。从图中可以明显看出，料层蓄热量随着料层高度逐步积累。当料层高度为40Omm时，其蓄热量可高达65%。由于烧结过程的自动蓄热作用，烧结料层温度随着料层高度下降逐步升高，这有利于各种物理化学反应的进行，使得各种矿物结晶充分，烧结矿结构得到改善。因此，随着料层的加高，烧结矿强度相应得到提高。虽然位于表层的烧结矿由于蓄热少，温度低而强度差，但是随着料层的增高，其表层部分所占比率相对变小，因此整个烧结矿强度得到提高，其平均粉末含量减少。同时由于厚料层作业蓄热多，这就有可能适当降低混合料配碳量以避免料层温度过高的不利影响。
