Defects in Cast Klin Tyres
The klin tyres are critical components of a rotary kiln. They support the full weight of the kiln, enhance the radial stiffness of the shell, and ensure smooth rotation on the rollers.
Klin tyres made by casting inevitably suffer from various defects: porosity, shrinkage, slag inclusions, cracks, cold shuts, sand holes, impurities, coarse grains, and segregation. These flaws lead to uneven hardness, localized stress concentration, and cracks, causing frequent equipment downtime for repairs. This can result in significant losses for industries such as cement and paper, where operations are continuous, automated, and enclosed.
Our Solution: Replacing Casting with Forging
Forged klin tyres can significantly reduce the inherent defects of cast klin tyres because:
Step 1: Large-deformation multi-directional forging breaks up coarse cast grains and reduces or eliminates internal porosity and looseness, greatly improving the density of the klin tyres.
Step 2: The ring-rolling machine applies strong pressure in both radial and axial directions, aligning the metal structure along the circumferential direction and further enhancing density and mechanical properties.
Step 3: Heat treatment is applied to further improve performance, followed by strict non-destructive testing and mechanical inspections after machining.
Highly Favored
Since their introduction, our forged klin tyres have quickly gained favor among leading rotary kiln manufacturers both domestically and abroad. The largest tyres have reached a diameter of 8.6 meters and a weight of 156 tons, and have been used in cement rotary kilns with a daily output of 10,000 tons.
