 The kiln tyre is one of the main components on the rotary kiln equipment. The function of the kiln tyre is to transfer the entire gravity of the cylinder (including the gravity of the refractory bricks, internal devices and materials) to the support roller, and the cylinder can smoothly rotate on the supporting roller, so the kiln tyre must have sufficient strength and Durability; at the same time, the belt is a part that strengthens the radial rigidity of the cylinder, so sufficient rigidity should be ensured.

Lime rotary kiln tyre Process introduction
1: simulation, modeling
Pnior to pouring, the casting process was numerically simulated using CAE software, and the process analysis and quality prediction of the product forming process were carried out, and the process of kiln tyre casting was continuously optimized. The metallurgical aids are complete in set and the overall size is well controlled. The water glass sand molding process can prevent the occurrence of hot cracks in the castings. At the same time, the pit shape is adopted, which is not affected by the season and has high production efficiency.
2: pouring, heat treatment
The qualified raw and auxiliary materials shall be put into the electric arc furnace for smelting in proportion, and the molten iron shall be sampled for spectral analysis. After passing the test, the pouring shall be carried out according to the principle of “low temperature fast pouring”, and the pouring time and temperature shall be recorded.
3: grinding, flaw detection
Finally, cut the riser, flash, etc. CHAENG has a professional polishing and finishing team, large-scale shot blasting equipment, which can effectively improve the appearance quality of the kiln tyre, make its surface finish meet customer requirements, and use advanced flaw detection equipment to non-destructively inspect each wheel to ensure internal Quality, strictly eliminate any defective products.
