Function of kiln tyre

The rotary kiln supporting device is a significant part of the rotary kiln. It bears the entire weight of the kiln and also plays a role in positioning the kiln body to ensure the rotary kiln can run safely and smoothly. The supporting device consists of kiln tyre, tug, bearing and blocking wheel.    
The kiln tyre, also known as the rolling ring, its function is to transfer the full gravity of the cylinder (including the gravity of the refractory bricks, internal devices and materials, etc.) to the supporting roller, and enable the cylinder to rotate smoothly on the supporting roller. Thus it must has sufficient strength and durability. At the same time, the kiln tyre is a part that strengthens the radial rigidity of the cylinder so it should have sufficient rigidity.

Advantages of AGICO's kiln tyre

Kiln tyre adopts ZG45, ZG35CRMO, ZG42CRMO and ZG45CRMO material, which can ensure its the strength and toughness By using ZG45 material and going through tempering and normalizing, the kiln tyre needs to be tempered and normalized, and the hardness will reaches HB170-200.  

1. Professional polishing and finishing team and large-scale shot blasting equipment to ensure the quality of inner and outer surfaces.
2. Professional flaw detection equipment makes non-destructive flaw detection on each Kiln tyre to ensure the internal quality of kiln tyre. For the key parts, the kiln tyre can reach the level 2 flaw detection standard of GB7233-2007, or design different processes according to the specific flaw detection standard of customers.   
3. High-end production machinery

• Two set of 30t electric arc furnaces
• 100+ set of high-grade/precise and advanced equipmen
• 7mx12mx4.5m natural gas CNC heat treatment furnace
• 8mx8mx4.5m large trolley-type shot blast machine
   

Installation of rotary kiln tyre

AGICO's perfect after sale service will make sure the installation of rotary kiln tyre a worry-free experience for our customer.   
However, the installation method usually adopts loop type. The rotary kiln tyre is not directly installed on the simplified section, but installed on the cushion plate, so that a natural ventilation channel is formed between the cylinder body and the rotary kiln tyre. On the one hand, it strengthens the heat dissipation; on the other hand, it reduces the heat conduction of the kiln body to the rotary kiln tyre to make the temperature difference between the inner and outer edges of the rotary kiln tyre become smaller. Thus, the change of thermal system in the kiln does not change the temperature difference much result in reducing the temperature stress on the rotary kiln tyre. When the kiln is running, the rotary kiln tyre and cylinder will produce relative sliding which will causing wear. At this time, the cushion plate will play the role of protecting the cylinder body. On both sides of the rotary kiln tyre, baffle or baffle ring is set to limit the axial movement of the rotary kiln tyre along the cylinder body.
