The refractories to be used as the blast furnace trough are required to have the characteristics of corrosion resistance against molten slag with high thermal conductivity to avoid spalling.To satisfy the above requirements,SiC is usually incorporated into the alumina based refractories.However,since the operating temperature of the furnace has tended to increase recently,a deterioration of the trough materials due to increased oxidation of the SiC is resulting in the lowering of the spalling resistance.In order to recover the lowering,a new technique to apply the pitch-coated alumina aggregates was successfully demonstrated.

武汉联合焦化AS煤气回收净化工艺产生约2 500 ～3 000 m3/h含氨20％ - 30％( w/w)废气,为了避免污染环境,目前采用的方法是将其在氨焚烧炉中烧掉;而烧结烟气氨法脱硫又急需15％-20％的浓氨水,需要外购大量液氨.两者结合变废为宝.将固定氨塔顶的氨气引出,经过蒸氨塔顶部压力调节装置、分离器、氨水浓度调节装置、水喷淋冷却系统、冷凝冷却器等装置后,生产出约20％的浓氨水进入储槽,用

介绍了宝钢2030带钢连续退火生产线（以下简称宝钢1＃连续退火机组）烟气余热系统状况,原有系统设计中,集气室后只有部分烟气余热用于预热带钢,而另一部分烟气直接排入大气,烟气排放温度约为330℃,所排放的烟气显热比较高.通过烟气余热回收工艺系统改造,设置烟气排放总管,接出三级换热系统,利用换热器的优化,最大化地利用了烟气余热,废气最终排放温度在200℃以下,有效的减少蒸汽耗量,实现节能降耗.另外还描
