1, the type of chain can be divided into two kinds of stainless steel and galvanized steel, each with its particular role in a specific scope. Therefore, the choice of the chain fence should do when we analyze specific issues, can really play a role in the chain fence. 2, the drive chain for chain products, there are now many other metals on the market shoddy, can not play a practical role in the chain fence in practice, so for safety considerations must use high-quality metal production chain. Purchase chain, the preferred Ning Xi Lu chain mesh factory, our factory is specialized in the production chain of the manufacturers, I plant with strong production strength, advanced production equipment, professional and technical personnel. Our products are sold: Guangdong, Shanghai, Henan and other parts of the country. Common chain waterproof and aging heat treatment method described chain now has been widely used in the transportation industry, and it has to be put into use after the heat treatment, the heat treatment method used on the chain, what does, and today we take a closer look at: Common chain heat treatment: annealing, normalizing, nitriding, carbonitriding, quenching, tempering, carburizing, boriding. Aging treatment artificial aging, natural aging process. Annealing, the workpiece is heated to 30-50 degrees above Ac3, holding a certain time, with the furnace cooled to 500 degrees at cooling in space. Normalizing, the steel is heated to above Ac3 Acm or stainless steel chain, an operation after removing heat from the furnace in air-cooled. Quenching chain, the steel is heated to above Ac3 or Ac1, rapid cooling after incubation in water or oil, coolant, has been unstable organization. Tempering the hardened steel reheated to a temperature below Ac1 chain manufacturers, cooled to room temperature after the heat treatment process heat. For the aging heat treatment method of the chain are: natural aging process, the workpiece is left at room temperature for prolonged storage conditions or natural aging phenomenon occurs, called the natural aging process. Artificial aging treatment, the use of the workpiece is heated to a higher temperature and a shorter time for aging treatment aging treatment, called artificial aging. Common chain waterproof and aging heat treatment method is mainly that, we must carry out the correct operation of the above description, the only way to fully display its performance out.
