炉缸堆积
hearth accumulation
lugang dulj-炉缸堆积(hearth aeeumulation)高炉炼铁过程中炉况失常的一种表现。指炉缸的有效工作空间缩小的现象。有中心堆积与边缘堆积之分。发生炉缸堆积的征兆是高炉接受风量及压差的水平明显低于正常;风压水平与风量不相对应;全压差及下部压差升高;风量超过一定水平时压差及风压突然升高,风量骤减,出现管道行程以至悬料(见悬料与坐料);休风后复风困难;风压在出渣、出铁前后升高及降低;炉喉煤气曲线CO。值在发生中心堆积时明显地高,出现边缘堆积时则相反;下料不匀,出铁前慢出铁后快;中心堆积时风口前焦炭不活跃;风口易涌渣及自动灌死并易烧坏;上渣增多且带铁多易烧坏渣口;边缘堆积时渣口难打开,风口常在下方烧坏;中心堆积时上渣温度高于下渣,边缘堆积时则相反;铁水物理热下降,含硫量升高;边缘堆积严重处冷却水温差下降。 炉缸堆积产生的原因是炉料质量差,粉末多,特别在焦炭质量差时更易造成中心堆积,而且影响的时间长;长时间过分发展边缘气流将引起中心堆积,而长时间过分加重边缘的装料制度将引起边缘堆积;长时间风口鼓风动能不足将引起中心堆积,反之,鼓风动能过高将引起边缘堆积;长时间冶炼含硅量高的生铁及使用碱性渣,将会加速石墨碳沉积;矿石还原性差,粒度大,直接还原率高,炉缸温度低而炉渣碱度高;水漏入炉缸等都会造成炉缸堆积。 发生炉缸堆积后的处理措施首先是改善原料特别是焦炭的质量,减少粉末;对中心堆积采用适当加重边沿的装料制度,为疏通中心缩小矿批,中心加焦缩小风口直径或临时堵风口以提高鼓风动能;对边缘堆积必要时扩大风口直径;如喷煤量高可适当减少,代以焦炭以提高料柱透气性并可减少未燃尽的煤粉进入炉缸;洗炉以降低炉渣碱度,由炼铸造生铁改炼炼钢生铁,加用锰矿;处理漏水。 (庄镇恶)
