Due to the overall downward trend of quality of crude fuel and the material leakage of central throat pipe, the air flow of blast furnace was disordered and the furnace condition was seriously abnormal. The trend for deterioration of furnace condition is significantly remitted and the blast furnace conditions gradually tend to be stable by such means as shrinking material batch, reducing coke load, increasing furnace temperature, decreasing alkalinity, strengthening the management of tapping, replacing central throat pipe and distributing chute, adjusting the distributing system, shrinking the area of intake air from tuyere, increasing the amount of water inflow of cooling wall and decreasing the temperature of water inflow.

在原燃料质量整体下行、中心喉管漏料、气流紊乱、炉况严重失常的情况下,高炉作业区通过缩料批、减轻焦炭负荷、提炉温、降碱度、加强出铁管理、更换中心喉管及布料溜槽、调整布料制度、缩小风口进风面积、增加冷却壁进水量、降低进水温度、精心操作等手段,使得炉况恶化的趋势得到明显缓解,保证炉况顺行。

在原燃料质量整体下行、中心喉管漏料、气流紊乱、炉况严重失常的情况下,高炉作业区通过缩料批、减轻焦炭负荷、提炉温、降碱度、加强出铁管理、更换中心喉管及布料溜槽、调整布料制度、缩小风口进风面积、增加冷却壁进水量、降低进水温度、精心操作等手段,使得炉况恶化的趋势得到明显缓解,保证炉况顺行。

原燃料  /  透气性  /  布料溜槽  /  气流  /  热负荷

Due to the overall downward trend of quality of crude fuel and the material leakage of central throat pipe, the air flow of blast furnace was disordered and the furnace condition was seriously abnormal. The trend for deterioration of furnace condition is significantly remitted and the blast furnace conditions gradually tend to be stable by such means as shrinking material batch, reducing coke load, increasing furnace temperature, decreasing alkalinity, strengthening the management of tapping, replacing central throat pipe and distributing chute, adjusting the distributing system, shrinking the area of intake air from tuyere, increasing the amount of water inflow of cooling wall and decreasing the temperature of water inflow.
