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 or Acm, an operation after removing heat from the furnace in air-cooled. Hardening, 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, 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 chain, 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. Due to the use of stainless steel conveyor chain more times, and there will be some rust in performance, the most important thing is how we deal with these rust. Today Ning 西卢 chain network plant technical staff for you to explain it: To remove rust scraper chain on that product, we can use the pickling paste, hanging chain can improve the surface finish. When carrying out the operation, the first painting in the first pickling paste surface transport chain, film thickness 0.5-2mm non-standard chain, conveyor chain reaction time is usually from 3 to 10 minutes or more stainless steel chain, below 0 ℃ or oxidation When used at thick-skinned, to be an appropriate extension of time, the process is the best scrub with a brush several double pitch chain, after complete removal of surface oxide, lime or better with alkali (water well) and rinse stainless steel chain machine, avoid returning rust stainless steel chain 201, the product appears as water, do not pour, shake or stir well to use. Scraper chain, chain Wuzhong, 西卢 chain network plant by plant Ningjin 西卢 chain network. Ningjin 西卢 chain network Factory (www.njxllw.cn) strong, credible, in Dezhou chains, sprockets and other industries has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Xi Lu chain network plant into the brilliant and you work for a better future!
