Casting rotary kiln tyre usually consist of a single annular steel casting, machined to a smooth cylindrical surface, which attach loosely to the kiln shell through a variety of "chair" arrangements. These require some ingenuity of design, since the tyre must fit the shell snugly, but also allow thermal movement. The tyre rides on pairs of steel rollers, also machined to a smooth cylindrical surface, and set about half a kiln-diameter apart.

Application:
We supply cement rotary kiln accessories. Kiln tyre and support roller, made by CSM, are first processed through steel casting in our foundry, it’s suitable for casting due to their super large & non-standard dimension, then going into heat treating (annealing, normalizing or quenching), the working procedure successfully insure the part obtaining high mechanical performance, finally the casting part is done finish machining for obtaining mounting dimensions to Rotary kiln.
Chemical composition and microelement of casting part are well controlled when in molten steel smelting. Since advanced technology and resin bonded sand are applied in our foundry, inner quality and visual surface quality are excellent.
Almost of all inner foundry quality are inspected by Ultrasonic test and Magnetic particle inspection. As requested, the quality class can reach Level II & III, and also ability to reach Level I, if special requirement. The testing standards are based on ASTM, ISO, DIN EN, BS, CA and AS.
Widely used in the area of cement mill,rotary kiln,shipbuilding,metallurgy,mine,sugar mill,powder plant,rail road,engine bed and so on. We have extensive experiences in producing kiln tyre. Welcome to sending drawings and enquiry!
