How to Choose the Right Material for Rotary Kiln Tyres

The rotary kiln tyre has two main types of wheel belts: solid rectangular and hollow box-shaped.
The shape of the solid rectangular tire is simple.
Due to the integral cross-section, casting defects are not prominent, and cracks are less common.
However, the rigidity of solid rectangular tires is smaller than that of hollow box-shaped tires of the same weight.
Hollow box-shaped tires have high rigidity, can increase the rigidity of the cylinder, and use less material, but have larger external dimensions and a complex cross-sectional shape.
During the casting process, defects such as cracks and even section breaks are prone.

The kiln tire mainly withstands three types of forces during the operation of the kiln: thermal stress, bending stress, and contact stress.
If these stresses are too large, the tire may be damaged or even fractured.
During the operation of the rotary kiln, the cylinder drives the wheel belt to rotate, and friction occurs between the wheel belt and the support rollers, causing a certain degree of wear on the tire.
Therefore, the material selection and casting of the wheel belt should ensure its wear resistance.

AGICO CEMENT uses ZG45 and ZG42CrMO materials, which can ensure the strength and toughness of the tire belt layer, thereby better supporting the kiln.
AGICO CEMENT’s wheel belts undergo a double-medium quenching process, ensuring uniform casting of all components.
With high quenching hardness and high toughness values, the kiln tires have excellent wear resistance and can adapt to various harsh working environments.
AGICO can process rotary kiln tires of various specifications according to customer drawings.

Kiln Tyre Material

Kiln tire material typically undergoes a detailed chemical composition analysis to ensure its suitability for the demanding conditions it faces.
The specific composition may vary depending on the manufacturer and the intended application, but a common analysis for kiln tire material may include:

  • Carbon (C): Contributes to the strength and hardness of the material.
  • Silicon (Si): Enhances the heat resistance and corrosion resistance of the material.
  • Manganese (Mn): Improves the material’s toughness and hardenability.
  • Phosphorus (P) and Sulfur (S): These elements are typically kept at low levels to avoid detrimental effects on the material’s properties.
  • Chromium (Cr): Enhances hardness, wear resistance, and high-temperature strength.
  • Molybdenum (Mo): Improves the material’s high-temperature strength and creep resistance.
  • Nickel (Ni): Contributes to toughness and impact resistance.
  • Copper (Cu): Can be present in trace amounts for certain alloying effects.
  • Vanadium (V): Enhances strength, toughness, and wear resistance.
  • Aluminum (Al): Improves the material’s oxidation resistance.

How To Choose Rotary Kiln Tire

Choosing the right material for rotary kiln tires is a critical decision that impacts the performance and durability of the kiln.
The selection process involves considering various factors to ensure optimal functioning under high temperatures, mechanical stress, and wear.
Firstly, understanding the operating conditions, including temperature range and chemical environment, is crucial.
Mechanical properties, such as hardness, strength, and toughness, must be carefully evaluated to withstand the load-bearing requirements and bending stress experienced by kiln tires.
Additionally, wear resistance is a key consideration to extend the lifespan of the tires and mitigate the impact of friction with support rollers.

Thermal stability is another essential factor, necessitating materials that maintain their strength and integrity at elevated temperatures.
Corrosion resistance becomes significant when kiln processes involve corrosive substances.
While cost considerations are vital, it is important to weigh initial procurement costs against long-term maintenance costs, as higher upfront expenses for a durable material may result in overall cost savings.
Consulting with the kiln manufacturer for specific recommendations based on their experience is valuable.
AGICO can process rotary kiln wheel belts of various specifications according to customer drawings. Welcome everyone to reach out for consultation.
