The wheel belt, also known as the rolling ring, is one of the main components on the rotary kiln equipment. The role of the belt is to transfer the full weight of the cylinder (including the gravity of the refractory bricks, internal devices, and materials, etc.) to the rollers and allow the cylinder to rotate smoothly on the rollers so that the wheels have sufficient strength and Durability; At the same time, the belt is a part that strengthens the radial rigidity of the cylinder, so it should ensure sufficient rigidity.
Technology introduction
The first step: simulation, modeling
Prior to pouring, Huaying CAE software was used to simulate the casting process, process analysis and quality prediction of the product forming process, and the belt casting process was continuously optimized. The metallurgical auxiliary equipment is well-equipped and the overall size is well controlled. The use of water glass sand molding technology can prevent the appearance of hot cracks in castings. At the same time, the pit shape is used, which is not affected by the seasons, and the production efficiency is high.
The second step: casting, heat treatment
The qualified raw and auxiliary materials were put into electric arc furnaces for smelting according to the proportion. Hot metal was sampled for spectral analysis. After passing the qualification, casting was performed according to the principle of “low-temperature fast pouring”, and the casting time and temperature were recorded.
The third step: polishing, flaw detection
Finally, cut the riser, flash, etc. Luoyang Yujie owns a professional sanding and finishing team. The large-scale shot peening equipment can effectively improve the appearance quality of the wheel belts, make the surface finish to the customer's requirements, and apply advanced flaw detection equipment to perform nondestructive testing on each wheel belt to ensure Internal quality, strict elimination of any defective products factory.
Product advantages
1, high strength belt, good durability
The rotary kiln wheels produced by Luoyang Yujie are made of ZG45 and ZG42CrMO materials, which can ensure the strength and toughness of the wheel belts, and thus play a better supporting role.
2. The wheel belt adopts advanced dual media quenching process in the casting process, with strong adaptability.
Luoyang Yujie's belts are treated with an advanced dual-media quenching process. Each part is forged evenly, featuring high quenching hardness and high toughness values. This wheel belt has good wear resistance and can adapt to various harsh working environments. .
3, the belt structure is simple, easy processing and manufacturing and routine maintenance.
