Описание: Mining round link chains are key components of underground conveyors, scrapers, and hoisting equipment in coal mines, metal mines, etc. They are made of high-quality alloy steel (such as 23MnNiMoCr54) through forging, heat treatment and other processes. They have high strength, wear resistance, and impact resistance. Its structure is a closed-loop design, and the chain links are tightly engaged to ensure stable operation under heavy load and high-speed conditions. The main parameters include pitch, chain link diameter, breaking load, etc. Common specifications include Φ14×50, Φ18×64, Φ26×92, etc., and the breaking load can reach hundreds of kilonewtons to thousands of kilonewtons. Heat treatment processes (such as quenching + tempering) further improve hardness and toughness, and surface polishing or galvanizing can enhance corrosion resistance. Application scenarios include fully mechanized working face scraper conveyors, coal plow chains, mine hoisting devices, etc., which need to be regularly checked for wear and fatigue cracks to avoid safety accidents caused by breakage. International standards such as DIN22252 and MT/T36-2011 regulate its production and inspection requirements to ensure efficient and safe operation in mines.
