高炉大料钟是高炉炉顶装料设备的重要组成部分,它使用的好坏直接关系到高炉的产量和炉况的正常运行。特别是采取高压、大风量的工艺之后,对大钟与漏斗的密封性要求更加严格。近几年来,我公司几座高炉的大钟使用寿命短,破损严重,特别是大钟与漏斗的密合部分破损极为突出,因此对高炉料钟的破损分析及对料钟结构的适当改造研讨是一个十分值得重视的问题。
Blast furnace chime bell blast furnace top charging equipment is an important part of its use is directly related to the blast furnace production and furnace conditions of normal operation. In particular, to take high-pressure, wind volume of the process, the bell and the funnel tightness requirements more stringent. In recent years, the clocks of several blast furnaces of our company have short service life and serious damage, especially, the close part of the bell and the funnel is extremely damaged. Therefore, the analysis of the damage of the bell of the blast furnace and the proper reformation of the bell structure Is a very worthy question.
