补充资料：炉况难行
炉况难行
tight furnace operation
Iukuongnanxlng炉况难行(tight furnaee operation)高炉炼铁过程中炉况失常的一种表现。炉况难行如不能及时消除，会由于炉料阻塞区域的扩大而转为悬料(见悬料与坐料)。炉况难行的征兆为炉料下降变慢，直至接近停滞或出现短时间的停滞;风压上升，风量下降，两者不相对应，透气性指数明显下降;炉顶温度上升，温度曲线变窄。处理方法是酌情减风量(如5%一10%或更多)，使压差低于正常值而且风量与风压相对应;如炉温充足可多减风温(如50一100℃)，采用发展边沿的装料制度并相应减轻负荷;加强炉前工作，出净渣、铁。 (庄镇恶)
