Flat link, V-LOCK vertical link and flat arc tool link have their own unique design shapes, and the shapes of the three connecting links are different.
In order to connect the reinforced mining chain and have the corresponding strength, Parsons specially designed the chain link. 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 the reinforced chain link meets the standard. This type of link can only be installed and used on the horizontal plane, and the chain is designed to mesh with the sprocket wheel according to the specification.
Due to the geological conditions of some coal mines, the underground water is corrosive, and even the water for some working equipment is corrosive, which will have an adverse impact on the chain, even grade C chain. If the internal stress in the manufacturing process is too high, it is easy to damage, and the chain with high strength (with the increase of hardness) is more likely to damage. In some environments, the chain is only a few weeks old from the beginning to the end. The chain shall be stored in a dry and ventilated place to avoid dampness and electrochemical corrosion of the chain. Because in the corrosion pit of high-strength chain, microcracks are often produced. The anti-corrosion chain produced by the ring chain branch of Zhangjiakou Coal Mine Machinery Co., Ltd. has a good effect on Overcoming Stress Corrosion and corrosion fatigue fracture. The chain is made of patented anti-corrosion steel, which has better overall anti-corrosion characteristics, strong toughness and corrosion resistance than galvanized and zinc impregnated chain.
