200000.00 Dollar US$ Industrial Sprocket Manufacturers Introduces The Use Process Of Mining High-Strength Circular Chain Fort McNair

  • Location: Fort McNair, District of Columbia, United States

The quality and performance of the high-strength circular chain used in mines as the traction part of the coal mine scraper conveyor will directly affect the working efficiency of the equipment and the coal output of the coal mine. The high-strength round link chain for mining is a consumable, which is easy to wear and damage during use. Once fracture and damage occur, work efficiency will be affected.

Therefore, in addition to choosing products with excellent quality and technology, high-strength round link chains for mining should also master the correct use and daily maintenance of the chain. Industrial Sprocket Manufacturers introduced the following items when using high-strength chain in daily use:

1. The size of the accessories such as the sprocket of the scraper conveyor should be the same to match accurately.
2. Select the corresponding chain quality grade.
3. Anti-corrosion chain can be selected according to working conditions. According to the corrosive water in some coal mines, choose anticorrosive circular chain that is basically not corroded by the external environment.
4. Avoid trauma as much as possible. The weakest link of the chain determines the quality of all chains. During the consignment movement, according to the packaging requirements, you should also be careful not to scratch the surface of the chain after arriving at the scene.

So, what material is the high-strength round link chain for mining made of?
Aiming at the current production status of 23MnCrNiMo54 grade circular chain with high content of precious metal alloying elements for large mines, a new low-cost, non-annealed Mn-Mo series low-carbon martensitic steel was developed. This steel is mainly an alloy of manganese and molybdenum, with a small amount of chromium, microalloyed niobium, and no precious element nickel. The CCT curve and hardenability of the steel were measured, the structure and mechanical properties of the steel under different heat treatment conditions were analyzed, and two c-level mining circular chains (26 mm92 mm, 30 mm 108 mm) were trial-produced under industrial production conditions. mm). The results show that the performance of large-scale chain products trial-produced with new steel grades fully meets the requirements of national standards. Compared with the widely used 23MnNiCrMo54 steel, the production cost is significantly reduced. It is a large-scale chain manufacturing material with market competitiveness.
