CHAENG has a large casting factory with large annual production capacity of steel castings. It has obvious advantages in casting parts of rotary kiln because of its rich experiences. CHAENG rotary kiln support rollers are made of steel materials ZA55, ZG42CrMo, etc. The ZG55 is carbon steel with strong tensile strength, and the ZG42CrMo is medium carbon quenched and tempered low alloy steel with strong impact resistance, higher fatigue strength, good wear resistance and high corrosion resistance, which greatly guarantees the quality of the rotary kiln support roller.

During long-term operation, the support roller shaft will generate heat. If it is overheated, it will cause friction. Part of the heat generated by friction will be taken away by lubricating oil, and the other heat will be dissipated to other components, which will reduce the thermal effect of the support roller shaft, reduce the lubrication state, and affect the load carried by the bearing, speed changes and cooling conditions. Therefore, at this time, adjust the heat insulation board on the bearing and the radiation temperature of the kiln body to the bearing in time, so as not to affect the operation of the supporting roller, resulting in low output and low profit of the rotary kiln.

CHAENG can customize the rotary kiln support roller according to customers’ drawings and requirements. What is important is that CHAENG has a professional technical team that conducts non-destructive testing through flaw detection equipment, strictly ensures the internal quality of the supporting roller.
