CHAENG kiln support roller material and manufacturing process
2020-12-31 | Editor:
The kiln support roller bears the whole weight of rotary kiln (including barrel, inside bricks, heat exchange device inside the kiln, raw material, rolling ring, gear ring), which makes the barrel and the rolling ring rotates smoothly on kiln support roller. Therefore supporting roller with strong endurance has become one important standard to judge the quality of rotary kiln.
CHAENG adopts high-quality steel materials with high tensile strength and good impact toughness, such as ZG55, ZG42CrMo, etc. so as to guarantee the quality but also has the advantages of bearing heavy load and good continuous operation.
CHAENG strictly controls every step of the manufacturing process to ensure the quality of the support roller for rotary kiln:
The first step: Simulation and modeling
Before casting, numerically simulate the casting process by CAE software to analyze the molding process, predict and optimize the product quality.
The second step: pouring and heat treatment
Sample hot metal and perform the spectral analysis. After qualification, start pouring according to the principle of "low temperature and quick casting", and the pouring time and temperature shall be recorded.
The third step: polishing and flaw detection
CHAENG uses advanced detection equipment for non-destructive testing to ensure the internal quality of the supporting roller, which strictly stops any defective goods from leaving the factory. CHAENG steel castings can meet level-two flaw detection standards.
