高炉的条式炉喉钢砖,下端部变形、开裂并向炉内方向凸出的问题,已为人们所重视.炉喉钢砖凸起后,它所构成的炉喉内型很不规则,直接影响炉料在炉喉的起始分布状态.而起始状态的炉料分布在很大程度上决定着高炉煤气流分布状况.这一点已被日本君津3号高炉所证实.图1示出了该高炉更换了凸向炉内的炉喉钢砖后,炉身至炉腰圆周方向各层的砖衬温度提高并趋向均匀,表明钢砖凸起后,对煤气分布和利用有显著影响. 当合理的炉料分布因炉喉钢砖凸起而遭
Blast furnace bar furnace throat steel brick, the lower end of the deformation, cracking and protruding to the direction of the furnace has attracted people attention.High furnace steel brick raised, it forms the throat type is very irregular, Directly affect the charge in the throat of the initial distribution of the state, while the initial state of the charge distribution largely determines the distribution of blast furnace gas flow.This has been confirmed by the Japanese blast furnace Junjin No. 3. Figure 1 shows the After the blast furnace replaced the throat steel brick protruding into the furnace, the brick lining temperature in all layers in the circumferential direction from the furnace body to the furnace waist increased and tended to be even, indicating that the steel bricks raised and had a significant impact on the gas distribution and utilization. Burden distribution due to furnace throat brick raised and suffered
