What are the ways of chain surface treatment?
A surface treatment, according to the need to use a certain diameter of the steel shot on the surface of the parts, the formation of uniform small pits, in order to improve the surface fatigue strength of the chain.
After the parts are heated to a certain temperature, they are cooled by chemical water solution and saponified to make the surface color of the parts appear blue. After the hair blue treatment of the chain appearance is beautiful, and rust prevention.
The parts are immersed in the phosphating liquid at a certain temperature to form a phosphating layer on the surface of the parts, which can make the surface color of the parts appear black or gray, improve the beauty of the chain and achieve the purpose of anti-corrosion. These phosphating liquid can be recycled, less pollution to the environment.
The nickel layer is formed on the surface of parts by electroplating or electroless nickel plating. The nickel plating layer can not only make the chain beautiful, but also prevent corrosion. Nickel chain - used in the open air.
The method of electroplating or chemical galvanizing is used to form a galvanizing layer on the surface of the parts. The galvanizing layer can not only be beautiful, but also be anticorrosive. Galvanized chain is generally suitable for open air occasions
In heat treatment equipment, various auxiliary media are used at high temperature to improve the structure of parts and physical properties.
After the chain is cleaned and refueled, slowly reverse the tooth plate. The chain links coming out from the rear should be able to be straightened. If some chain links still maintain a certain angle, it means that they are not smooth and belong to a dead knot, which should be adjusted. The damaged chain link must be replaced in time. It is recommended to strictly distinguish the three types of pin shafts and use the connecting pin shafts for the maintenance chain.
Conveying chain is an essential part of mechanical equipment, which is related to the daily production efficiency and work quality of equipment. In addition, the lubrication of the chain is also very important, but we can not blindly apply all lubricating oil to the chain
Chain conveyor line can also be called chain line. Chain conveying line is a chain as a traction and carrier for conveying materials equipment, the chain can use ordinary sleeve roller conveying chain, can also use a variety of other special chains (such as deposit chain, double speed chain). Chain conveying line mainly conveying pallets, large turnover boxes, etc.
