井式炉的结构和维护方法

Structure and maintenance method of well-type furnace

介绍球化退火井式炉的基本结构,对自预热燃烧器的结构和工作原理进行详述。提出设备重要部件如内筒及对流筒、炉底搅拌风扇、温控和电控系统维护过程中需要注意的问题。在井式炉使用过程中除了检查循环冷却水、炉底搅拌风扇、气氛压力、炉体密封、热电偶等是否正常外,应及时对甲醇裂解炉和甲醇裂解气管道进行除炭。在使用和维护时,应及时检查炉体的密封状况和设备机械传动件的润滑情况,控制进炉物料数量,保证井式炉工艺稳定。

To introduce the basic structure of well-type furnace for spheroidizing annealing. The structure and working principle of burner with integrated recuperator were expounded. The problems needing to pay attention to in major equipment componeut such as inner barrel and convection barrel, agitating fan in furnace bottom, temperature control and electric control system maintenance. Despite examining the regular of circulating cooling water, agitating fan in furnace bottom, atmosphere pressure, furnace sealing, thernlocouple and so on in well-furnace process operation, the decarbonization should be done on methanol pyrolyzing furnace and methanol pyrolyzing gas tube in time. The sealing condition of furnace and the lubricating of equipment mechanical driving parts should be examined in time while in using and maintenance. The quantity of loading should be controlled to guarantee the stability of the well-furnace process.
