Mining flat link, the market is also called chain link or block link. The material of the chain link is high-quality alloy steel, which can only be used for the flat link. Special design is adopted for the special structure of the sprocket wheel, which increases the thickness of the easily worn part of the chain link, thus greatly improving the service life of the chain link. The connecting link is fixed by a locking bolt, which is very convenient for installation and disassembly.

The use of chain link

The chain link is mainly used for the connection between the mining ring chain specified in GB / t1218 and the mining high strength compact chain specified in MT / T 929, which are used by the scraper conveyor, transfer machine and coal plough in the coal mine. The standard for product design, manufacturing and inspection is Q / aid01-2013 technical specification for flat link for mining.

Process design of chain link

In order to connect the reinforced mining chain and have the corresponding strength, the chain link is designed specially. The strength of the link is 25% higher than that of the ring chain or flat chain of DIN standard grade 2. Through careful selection of materials and special heat treatment process, the performance of this reinforced chain connecting ring meets the second part of din2258:2003 standard. This type of link can only be installed and used on the horizontal plane. The installation specification design makes the chain and sprocket wheel mesh.
