The rotary kiln supporting wheel bears the weight of the entire rotary kiln part, mainly the cylinder body, the lining brick, the heat exchange device in the kiln, the material, the rolling ring and the ring gear, and the cylinder body and the rolling ring can rotate smoothly on the supporting wheel, so The super-powered roller has become one of the standards for measuring the quality of rotary kiln products. The support rollers produced by Ascendas cast steel are generally made of ZG55, ZG42CrMo and other materials. On the one hand, the quality of the support roller is ensured, on the other hand, it has the advantages of large load bearing capacity and continuous operation. The roller is heat-treated during heat treatment. The tempering process makes the surface hardness of the outer circumference of the roller high, which greatly guarantees the quality of the rotary kiln roller device.

The process is as follows:
1. Simulation, modeling
Before casting, large casting and processing manufacturers use professional software to digitally simulate the casting process, and perform process analysis, quality prediction and optimization on the molding process of the product. The metallurgical aids are complete in set and the overall size is well controlled. The water glass sand molding process can prevent the occurrence of hot cracks in the castings. At the same time, the pit shape is adopted, which is not affected by the season and has high production efficiency.
2. Pouring, heat treatment
The qualified raw and auxiliary materials shall be put into the electric arc furnace for smelting in proportion, and the molten iron shall be sampled for spectral analysis. After passing the test, the pouring shall be carried out according to the principle of “low temperature fast pouring”, and the pouring time and temperature shall be recorded.
3. Polishing and flaw detection
Finally, cut the riser, flash, etc. The company has a professional finishing polishing team and large-scale shot blasting equipment, which can effectively improve the appearance quality of the supporting wheel, and make its surface finish meet customer requirements. It has advanced flaw detection equipment for non-destructive testing to ensure the internal quality of the supporting wheel and strictly eliminate it. Any defective products are shipped.
Huixian Tengfei Cast Steel is a large-scale cast steel production base, which can produce large-scale steel castings with a single piece of more than 1 ton, such as slag pots and slag pots in metallurgy; support wheels, large gears and hollows for cement and chemical machinery parts. Shafts, belts, rolling rings, rocker arms, booms; press bases, arches, fuselage for forging equipment fittings; moving jaws, frames, center castings for crusher fittings; end caps for coal mine fittings; Products such as hinges and hinges will surely meet the needs of different industries.
