Special treatment process chain, a chain plate, heat treatment chain, chain plate tend to thin diffusion layer 1.; 2. hardness gradient replace carbon concentration gradient measured to obtain a carbon concentration gradient relaxation, brittleness, improve strength; 3 . using controlled atmosphere hardening and carbonitriding; 4. propane gas carburizing; 5. reduce dependence on the converter, a thick nitrided layer product by the box-type multi-purpose furnace or shaft furnace gas substitution; 6. replaced by agent oil quenching, 10A standard chain, in order to reduce pollution. Second, special techniques such as plating, stainless steel heat treatment, Chromizing, circle cold riveting technology, plate punching punching tooth technology, S-type steel roller chains profiled attachment bending, etc. can be gradually solved effectively. Third, the two ran together, and acts to eliminate by the end of automatic on-line effects of oil, grease role. Fourth, select the appropriate operation mode 1. The factory is divided by product category; 2. Job types of plant and equipment layout; it should be said, when the enterprise scale development to thousands of different types of stainless steel chain plate chain products together in a factory district Production is unwise. 3. When the external conditions are ripe (quality, price, delivery time), the chain parts can be produced or outsourced diffusion. Ning Xi Lu chain mesh factory is good stainless steel chain manufacturers. Speaking of chains, Changchun chain, sprocket can not fail to mention. Then you know the structure of the sprocket it? Sprocket structure generally are: overall structure 1. Generally used in standard chain P = single, double, single, double flange sprocket processing 38.1 or less. 2. The welded structure. Mainly used in medium and large size single and double flange sprocket processing. When machining the flange part of the bar car is convex. After the ring portion can sheet cutting diameter and shaft hole, the hole end car out of the welding groove set into the welding flange portion. When welding to both ends of the welding, stainless steel chain specifications, such as using low hydrogen electrodes T506 welding and so on. 3. Casting sprocket. Mainly used in large sprocket processing, and processing only the ring gear machining, flange both end surfaces, outside and inside diameters and keyway, stainless steel chain manufacturers, and then processed tooth. Central sprocket are cast. Casting sprocket materials in general, there are two, cast iron and steel as HTl5O, HT2O0 and ZG310-570 (ZG45). The forging sprocket. Mainly used in a larger force, the production of large-sized sprocket. Forging, whether they are single flange or double flange type, generally forging a convex axial bore leaving enough allowance, lower material utilization and high costs.
