Rotary Kiln Tyre, also known as the kiln roller ring. The role of the Kiln Tyre is to transfer all the gravity of the cylinder (including the gravity of the firebrick, internal devices and materials, etc.) to the support roller, and to make the cylinder physically rotate smoothly on the support roller, so the kiln tyre should have sufficient strength; At the same time, the kiln tyre is a part that strengthens the radial steel of the cylinder, so it must be ensured that it has sufficient stiffness.

CHAENG (Xinxiang Great Wall) uses ZG45 and ZG42CrMO materials for casting, which can ensure the strength and toughness of the  kiln tyre, so as to better play a supporting role. At the same time, the advanced dual-medium quenching process is used to make each part cast evenly, and has the characteristics of high quenching hardness and high toughness value, so that the wheel belt has good wear resistance and can adapt to various working environments.
