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: chain common heat treatment methods: big ball chain 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 stainless steel chain manufacturer, holding a certain time, with the furnace cooled to 500 degrees at cooling in space. Normalizing, the steel is heated to above Ac3 or Acm, an operation after removing heat from the furnace in air-cooled. Hardening, the steel is heated to above Ac3 or Ac1, heat rapid cooling after bending plate chain in water or oil coolant, the organization has been unstable. Tempering the hardened steel reheated to a temperature below Ac1, after cooling to room temperature incubation of the heat treatment process. 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. Some form of damage stainless steel chains 1. Wear damage in open drive or confront the worst, poor material stainless steel chains, wear is often the primary method for stainless steel chain of transmission damage. Stainless steel chain links and chains worn total length elongation, meshing point along the side tooth profile job addendum to move the chain, eventually resulting in tooth or jump off the chain when engaged. The primary wear produced in the outer link. When the pin and the outer wear sleeve group, hinge gap increases, thus making the chain elongation. Within the chain steadily from the same side of the bus depends on the adjacent roller, since the roller table sleeve round appearance and wear very little, so the inner links is simply not extended. When the stainless steel chain wear elongation reach 3% of midnight, stainless steel chain will be due from chain and damaged, then the elongation of the outer link may reach 6%. In order to advance the stainless steel chain wear life, we must look smooth and full of useful groups to Zhou Li constraint in the range of allowable work load. 2. Fatigue damage has excellent wear resistance smooth functioning of the premise and stainless steel chains are usually damaged due to fatigue damage. Due to the presence of stainless steel chain tight side and the loose side, and thus accept the size stainless steel chain parts alternating loads. In every link revolves in the situation by force tensile stainless steel chain and turns, pin shear stress condition, kneading and turns, rollers accepted kneading and impact sleeve is subjected to kneading, shear and impact. Under alternating load effect parts to crack - crack, resulting in fatigue fracture. Stress number of rounds can be seen as the impact of the number of stainless steel chain stainless steel chain parts. In practice, each revolving accounts stainless steel chains usually ponder when only impact hinges into engagement, so the stainless steel chain considered the impact of the number of orbiting per minute per minute.
