Trolley WheelIt is a type of cast steel part and also one of the main components on the rotary kiln equipment. It bears the entire weight of the kiln section and ensures the cylinder and roller ring can rotate smoothly on the support wheel. During the actual casting process, its casting technique and quality are crucial.
Casting requirements
The thrust wheel supports the rotation of the rotary kiln, and the ball mill thrust wheel bearing is the key to the normal operation of the rotary kiln. Therefore, the durability of the thrust wheel has become one of the standards for evaluating the quality of the rotary kiln and ball mill.
Xinxiang Great Wall boasts a large-scale foundry base in the northern Henan region, with a significant annual output of cast steel products, particularly in the casting of components for powder grinding equipment like trailer wheels, utilizing a well-refined casting process.
Step: Simulation, Styling
Prior to casting, use Huazhu casting method.CAE software digitally simulates the casting process, conducts process analysis, quality prediction, and optimization for product shaping. Metallurgical auxiliary equipment is complete, with good overall size control. Water glass sand molding technology is used, which can prevent the occurrence of casting hot cracks. Additionally, earth pit molding is adopted, unaffected by seasons, and ensures high production efficiency.
Step 2: Casting, Heat Treatment
Qualified raw and auxiliary materials are proportionally placed into an electric arc furnace for smelting, the iron melt is sampled for spectral analysis, and upon passing the test, proceed accordingly.Pour according to the "Low Temperature Quick Pour" principle, and record the pouring time and temperature.
Step 3: Polishing and Non-Destructive Testing
Finally, trim off the gating system, sprues, and flash.
Xinxiang Great Wall boasts a professional polishing team, large shot blasting equipment, which can effectively enhance the appearance quality of the truck wheels, achieving the required surface smoothness for customers. Additionally, we utilize advanced non-destructive testing equipment to ensure the internal quality of the truck wheels, strictly prohibiting any defective products from leaving the factory.
Product Advantages
1. The production of casters generally utilizesZG55、ZG42CrMoThe material ensures the quality of the carriage wheel while also providing the advantages of high load-bearing capacity and excellent continuous operation.
2. The sprocket wheel uses a rolling bearing assembly, featuring a simple structure and easy maintenance.
3. Xinxiang Great Wall employs normalizing and quenching processes in the casting of the bearing wheels, ensuring that the surface hardness of the outer circle of the bearing wheels exceeds 200HB, thus guaranteeing the quality of the rotary kiln bearing wheel assembly.
Xinxiang Great Wall, with years of experience in powder grinding equipment manufacturing, produces idlers that have been positively received by clients for use in the construction of multiple cement production lines domestically.
Note: Xinxiang Great Wall can process and customize various types of roller models. As long as you have drawings and the weight of each piece is one ton or more (inclusive), please contact us for processing and customization. Factory direct sales, high quality at low prices!
