Reason For Corrosion

Industrial chain is a special conveyor chain application for special industry. The material of chain are usually carbon steel, alloy steel or 304 stainless steel. They can be both used for industry area for different applications. It plays an important part in driving, and lifting.  And lots of areas need industrial chains. We offer four reasons that causing chain corrosion as followings:
1.Companies have not obeyed the rule of cleaning rust and oil seal packaging. For example, the chain has contacted with corrosive liquids or gases.
2.The quality of rust prevention and cleaning products have not reached the technology requirements.
3.The quality of chain is decreased gradually because of the price of chain dropped again and again.
4.Some companies environment are bad. It usually has high levels of harmful substances in the air and working space is too small. It will be difficult to carry out effective anti rust treatment. Certainly there are workers in violation of regulations with the hot weather.
As we all know,the development of chain industry is very rapidly at present and types are increasing gradually. So it is difficult to choose. We should know various advantages of the chain in order to do the best choice.

Conveyor chain

Conveyor chain is same as transmission chain and also composed by a series of bearings. The most important feature for the conveyor chain is large and heavy. They are fixed by chain plate which with binding effect. So the positional relationship between each other is very accurate. Roller chain rotate on the bearing that includes a pin or a sleeve. Pin and sleeve are also subjected to surface hardening treatment, so it will allow them hinged at higher pressure. While it can withstand the pressure transmitted through the rollers and the shock when engaged.
Various intensities conveyor chain also has a range of different pitches. Minimum chain pitch depends on the strength requirements to the sprocket teeth. However the maximum chain pitch depends on the strength of chain plate and generic chain.
Conveyor chain is widely used for transporting all kinds of boxes, bags, trays and other pieces of cargo. Bulk materials, small items or other irregular items should be put on the pallets or into the crates for conveying. It can convey heavy materials or bear big shock. Its structure could be divided into two type  by driving mode. They are power lines and power roller drum line. Certainly, it can be divided into three types by arrangement form. They are horizontal conveyor drum line, inclined conveying drum line and turning drum line. We can also designed with customer requirements.
