Q: Why the prices are very different for same size chain in China chain factories.
A: There are lots of ways to less the cost in chain production.
-The prices from some steel factory are cheaper but the physical properties are poor.
-Reduce production process: Plate material annealing, twice punching plate hole, centerless grinding, shot peening, chain pre-strength, etc.
-Use cheaper material for pin, bush and roller.
-Use thinner chain plates.
-Shorter the heat-treatment time or overload in furnace each time.
Q: Why we never use 45 (1045) to produce conveyor chain plate.
A: In Europe, it is common to use 1045 steel as conveyor chain plate to less the cost. However, the steel 1045 made in China cannot reach to our requirements. The main problem is big deformation after heat-treatment. It will be difficult to control the pitch accuracy.
Q: Why we use 40Mn as plate material.
A: 40Mn has higher C element and Mn cement. Mn can Increase hardening depth of steel, lower quenching temperature, refinine the pearlite structure to improve its mechanical properties. Mn content in 40Mn steel is 0.7~1.0. It is ideal ingredients and can get good strength and fatigue life. When Mn content increase, metal crystal particles gradually decrease and reach a certain value after it reach to 0.5 and the tensile and hardness also reach to a certain value. After it is higher than 1, the fatigue life of steel decreased.
Q: Why the prices may very different for similar size conveyor chain.
A: We offer the prices according to the material and chain producing process. We design the conveyor chain basis on application environment. Different environment (normal, high wear resistance, heady-duty, slightly corrosive, corrosive, etc.) will use different material with different producing process. If the chain used in corrosive environment also heady-duty, we need to use best material. The plate holes, bush, pin and roller may will be produced by CNC material and heat-treatment by multi-purpose furnace. The price will be very high.
Q: Why we can say we are China engineer chain specialist.
A: We have more than 45 years experiences in engineer chain, serving lots of industry giants in China. During analysis lots of imported conveyor chain, we are familiar with the chain design and producing process from the world first class chain factories.
