What is the material of conveyor electric roller?

Because the electric roller of the conveyor is made of metal, it will be damaged by vibration other combined forces in the process of production operation, resulting in the wear of roller bearing position. For the maintenance of conveyor belt roller, the traditional methods include surfacing, thermal spraying, electric brush, etc., but they all have relative disadvantages: they can eliminate the thermal stress caused by the high temperature of maintenance welding, which is easy to cause material damage lead to bending fracture of components, the brush coating is limited by the coating thickness, it is easy to fall off. Both methods use metal to repair metal, which cannot change the "hard to hard" matching relationship. Under the combined action of various forces, the rubber roll will still be worn again.

According to different production materials, carbon steel roll can be divided into low carbon steel roll high carbon steel roll. The carbon content of low carbon steel drums ranges 0.1% to 0.3%. Mild steel is easy to machine, such as forging, welding cutting. Low carbon steel materials are also commonly used in chain, rivet, bolt bearing spare parts manufacturing. Low carbon steel drum is wear-resistant mechanical parts. The carbon content of high carbon steel cylinder ranges 0.6% to 1.7%, which can be quenched tempered.

Cutting tools such as drills, taps reamers are made of steel with a carbon content of 0.9% to 1%. High carbon steel is usually rolled into angle steel, channel steel, I-beam, steel pipe, steel strip steel plate, used to manufacture various building components, containers, boxes, furnaces agricultural machinery. High carbon steel barrel has high surface temperature good wear resistance. Sometimes, the manganese content in carbon steel will increase appropriately, the addition of trace vanadium, titanium, niobium other alloying elements can greatly improve the strength of steel. If the carbon content in the steel is reduced a small amount of aluminum, boron carbide forming elements are added, the ultra-low carbon bainite group can obtain higher strength maintain the good plasticity, toughness plasticity of the carbon steel roller.
