AGICO Rotary Kiln Tyres
AGICO CEMENT undertakes the processing and customization of kiln tyres and other spare parts for the rotary kiln. With the support of complete casting factory lines and cutting-edge equipment, our experienced team can customize and produce various models of rotary kiln tyres for customers according to their drawings.
The tyre is a vital component of the driving assembly of the rotary kiln. Its main function is to support the kiln cylinder on the kiln support rollers, and transfer the weight of the cylinder and materials to the kiln-supporting device, so that the cylinder can rotate stably on the support rollers. AGICO rotary kiln tyre has high strength and good durability, and it is adjusted according to the specific conditions of the customer’s rotary kiln to make the tyre meet the customer’s requirements and local standards.
Why Choose Us
The weight of the rotary kiln itself, together with the weight of the materials in the kiln, can range from tens of tons to hundreds of tons, so the kiln tyre requires sufficient strength and durability to bear them. And because the tyre is a part to strengthen the radial stiffness of the kiln body, it needs to have sufficient stiffness. AGICO tyres are generally made of ZG310-570 or ZG42CrMo alloy steel according to Chinese standards, and can also be cast with materials required by customers to ensure that the tyres are sturdy and durable.
Strong Capacity in the Industry
AGICO has strong production and processing capacity and can deliver your products in both good quality and short time. Our factory has complete and mature casting production processes and various advanced production equipment. Our casting equipment includes two large electric smelting furnaces and two 9m long natural gas heat treatment kilns. Casting equipment includes large vertical lathes, gear hobbing machines, boring and milling machines, drilling machines, etc.
Rigorous Casting Process
Our tire is normalized and tempered in the casting process, and processed in strict accordance with international mainstream standards. The surface hardness of its working part is not lower than HB170, and the casting blank is free of cracks and pores. The machining deviation is small and the precision is high. The thickness of the inner and outer wheel circles of finished tyres shall be controlled not less than 95% of the design size and not more than 105% of the design size.
Rich Experience in Kiln Tyre Processing
AGICO has been engaged in processing large steel castings for more than 20 years, and has rich experience in the manufacturing of rotary kiln tyres. We have continuously summarized experience, improved the manufacturing process, and actively introduced new equipment and technology in the production process over the years to keep pace with the cutting-edge international level. Our strength in the industry is at the top level in China, and our products are widely sold at home and abroad.
Kiln Tyre Details
When the rotary kiln is running, the tyre will bear the temperature difference stress, bending stress, and contact stress. The strength of the old and worn tyre will decrease, which may cause the tyre to be damaged or even broken due to the inability to withstand these forces, leading to production accidents. In order to prevent accidents, in addition to regular inspection and maintenance in daily operation, products with high strength and good wear resistance should be selected when replacing new kiln tyres. AGICO kiln tyres have excellent strength and toughness, are firm and durable, and can better play a supporting role, which is your good choice.
Installation of Kiln Tyre
The kiln tyre plays an important role in supporting the rotary kiln, and its installation quality is directly related to the operation efficiency of the whole kiln system. Therefore, special attention must be paid to controlling relevant details during its installation.
1. The tyre is not directly installed on the cylinder of the rotary kiln, but on the base plate. The tyre is looped on the cylinder, and there is an appropriate gap between them to form a natural ventilation duct, which can improve the heat dissipation of the cylinder surface, as well as reduce the heat conduction of the kiln body to the tyre, reduce the temperature difference between the inner and outer edges of the tyre, and thus reduce the temperature stress of the tyre. During the operation of the rotary kiln, the tyre belt and the kiln body experience relative sliding along the axial direction, resulting in wear. At this time, the base plate can play a role in protecting the kiln body.
2. When installing the tyre, it is very important to adjust its axis and the axis of the support rollers to keep them in the same straight line. If the axes of the two are not consistent, it will not only reduce the rotation rate of the kiln cylinder, but also increase the wear of the tyre and the support rollers.
3. The surface of the tyre shall be lubricated timely after installation. The tyre of the rotary kiln is an important part to drive the cylinder to rotate. If its surface is too rough and the resistance is too large, it will not only reduce the rotation rate of the cylinder, but also cause the over-burning of materials.
