Processing technology of conveyor chain:

1. Quenching: Each part is heated to a certain temperature. In the configuration of heat treatment, the heating and storage time is confirmed, and then it is cooled in different media according to requirements, and the hardness of the parts can be improved.

2. Carburizing, heat treatment is set in the heat treatment, part of it is heated to a certain temperature, kept for a certain time, and then enters the carbon-containing medium, and the carbon enters the appearance of the part to improve the hardness and wear resistance.

3. Tempering: Partial heating after quenching and quenching, the temperature after heat treatment can determine the temperature, and cooling after heat preservation. The end of the part can be of low quench hardness, quench stress and toughness.

4. Abstract: The principle of organic polymerization of polymers is accepted, and heat and heat make the film black during the heat treatment process. It has the characteristics of light resistance, corrosion resistance, rust resistance, low labor intensity, and improved production environment.

5. Shot peening: a punishment for appearance, the steel ball with a certain diameter must be surface-treated to form a small and symmetrical pit to improve the appearance of the chain.

6. Blue color: After heating to a certain temperature, the chemical solution is cooled and saponified to make each part appear blue. Finally, use the blue method to deal with the penalty chain on the surface of the chain, and other anti-rust effects. What is not enough is that these chemical solutions cause a lot of pollution to the environment.

7. Phosphate ester: Phosphating treatment is carried out at a certain temperature, at a certain temperature, to make it form a phosphating layer in terms of appearance, appearance, color, etc., and make it partially black or gray. At the same time, improve the chain to achieve the purpose of corrosion. These phosphate liquids can be recycled with less environmental pollution.

8. Electroplating: Accept the main parts of electroplating or chemical galvanizing, so that the zinc coating appears on the surface. The zinc coating is both aesthetically pleasing and rust-resistant. Galvanized chains are also practical in the open air.

9. Nickel plating: In order to accept the main reason for nickel plating or nickel plating, the nickel plating layer is formed on the surface of the parts, and the nickel plating layer is both beautiful and has anti-corrosion effect. Nickel-plated chains are usually used in open spaces.

10. Oiling: After the conveying chain is oiled, it can prevent the chain from rusting, and it is more shiny.

The accuracy of chain length shall be measured according to the following requirements:

1. The front chain has been cleaned

2. Measure the EK chain on the two sprockets, which should support the upper and lower sides of the measurement chain

3. The pre-measured chain should be held for 1 minute before applying one third of the minimum tensile load

4. When measuring, the measured load is applied to the chain so that both ends of the chain are in tension. The chain should ensure the normal tooth gap of the chain

5. Measure the center distance of the two sprockets

Measuring chain extension:

1. In order to eliminate the gap of the entire chain, a certain tension is applied to the chain

2. In order to reduce the error in the measurement, make the measurement in sections 6-10.

3. Measure the inner L1 and outer L2 dimensions of the measurement section to determine the dimension L = (L1 + L2)/2

4. Find the elongation length of the chain, which is the opposite of the threshold used for chain elongation in the previous paragraph
