Mining Chain
Mining Chain
Mining chain is mainly used for mining, with high requirements and large toughness coefficient. At present, the domestic mining chain is divided into grade B, grade C and grade D according to the strength grade, and the materials are 25MnV and 23mncrnim654. It is divided into flat chain, reinforced chain and anti-corrosion chain: This chain reinforced mining ring chain series, which adopts forged vertical chain.Rings and special heat treatment have high tensile strength, long fatigue life and high toughness of domestic chains. The best hardness of each ring reduces the wear between links and significantly improves the service life.
