摘　　要：某水泥厂拟将回转窑规格由ϕ4.8m×74m改造为ϕ4.3m×74m,为降低改造成本,采用三档支承和轮带利旧、设计制作双层松套式垫板系统的改造方案。重点阐述了双层松套式垫板系统的结构设计、加工制作、现场安装及日常运维。双层松套式垫板系统主要由内外圈垫板、挡环、过渡套筒等组成,设计时,需确保窑筒体及轮带与过渡套筒间保持一定的间隙值和滑移量;加工时,过渡套筒焊接完成后应作整体去火处理;安装时,垫板系统、轮带需预先与筒体大段节套装;维护时,应注意垫板系统的润滑、间隙值检测并及时更换垫板。本次改造共历时4个月,投产后回转窑运行稳定,实现了改造预期目标。A cement factory plans to change the kiln size fromϕ4.8m×74m toϕ4.3m×74m.In order to reduce the cost of transforming,the reconstruction scheme adopted the original supports and tyres,redesign and manufacture the double loose pads system.This paper focuses on the double loose pads system structure design,machining,on-site installation and daily operation and maintenance.The double loose pads system is mainly composed of inner and outer pads,retaining rings,transition sleeve,etc.The design should ensure a certain gap value and slippage between shell,tyre and retaining ring.During maching,the transition sleeve should be stress-relief annealing treatment;when installing,the pads system and tyre must be pre-assembly with large sections of the shell;during maintenance,it should pay attention to the lubrication and gap value detection of the pads system and replace the pads in time.The transformation took 4 months.The rotary kiln runs stably after being put into operation,and the expected goal of the transformation has been achieved.
