Nitrogen generators, particularly those adopting Pressure Swing Adsorption (PSA) technology, produce nitrogen by separating it from air. They consist of core components like adsorption towers and carbon molecular sieves, operating through cyclic adsorption and desorption processes. PSA nitrogen generators are renowned for their high efficiency, on-site gas supply capability, and wide applications in industries such as metallurgy, pharmaceuticals, and electronics.
Of course, the application value of nitrogen in heat treatment is not limited to this; it can be widely involved in all aspects of heat treatment:
Vacuum heat treatment: When nitrogen is used as a cooling medium for nitrogen-charged pressurized oil quenching, adjust the nitrogen pressure of the nitrogen generator to improve the hardenability of steel parts and protect the electric heating elements of the vacuum furnace;
Controlled atmosphere: Nitrogen, as a diluent gas, can reduce the consumption of raw gas and the formation of carbon black;
Carbonitriding: Nitrogen produced by the nitrogen generator can be used for anti-oxidation cooling after carburizing, reducing the internal oxidation degree of steel parts, and improving the gas decomposition rate as well as the fatigue strength and breaking resistance of parts;
Protective gas, safety gas: Purge and exhaust in the furnace, and airtight sealing of the furnace door; when the gas supply is cut off, nitrogen produced by the nitrogen generator can be sent into the furnace to prevent gas explosion.
Considering the economic benefits of production, the lower the nitrogen usage cost, the better. It is recommended to use PSA nitrogen generation. Compared with directly purchasing bottled nitrogen for use, it is more cost-effective. Basically, only one-time investment is needed to eliminate a series of management problems such as transportation, storage, and handling associated with bottled nitrogen. At the same time, the equipment has a high degree of automation and low maintenance costs. In long-term use, it can achieve good cost-effectiveness, making it particularly suitable for the long-term nitrogen demand of small and medium-sized enterprises.
Advantages of PSA Nitrogen Generator in Metal Heat Treatment
In the machinery manufacturing industry, metal heat treatment is a very important process. Compared with other processing technologies, heat treatment can change the internal microstructure or surface chemical composition of workpieces, playing a role in improving the intrinsic quality of workpieces.
In fact, the technology of metal heat treatment was recognized and applied as early as the Bronze Age. But even today, metal heat treatment still holds a pivotal position. Someone once commented like this: mechanical processing is like surgery, and heat treatment is like internal medicine; the quality of heat treatment technology can represent the strength of the core competitiveness of the manufacturing industry.
The metal heat treatment process generally includes three processes: heating, heat preservation, and cooling. Different processes should be connected with each other without interruption. Among them, the heat preservation process may or may not exist.
During metal heating, a major difficulty is to prevent the workpiece from oxidation and decarburization (that is, the reduction of carbon content on the surface of steel parts). This will affect the surface performance of the workpiece, leading to unsatisfactory metal heat treatment effects. A common solution is to place the metal in a protective atmosphere (such as nitrogen) to separate the metal from oxygen before processing. The nitrogen used here needs to have relatively high purity and maintain a stable and continuous supply, so that the metal workpiece can achieve a relatively good heat treatment effect.
In addition to PSA Nitrogen Generator, we also produce VPSA Oxygen Generators,PSA Oxygen Generators, storage tanks, heat exchangers and other products.
