Analysis And Selection Of The Development Direction Of Heat Treatment

---

With the development of society and the advancement of science and technology, heat treatment technology is also constantly improving, so what is the development trend of heat treatment technology? Shanghai Gehang Vacuum Technology Co., Ltd., the manufacturer of vacuum heat treatment furnace, makes a simple sharing based on years of understanding:

First, less oxidation-free heat treatment is replaced by heating with protective atmosphere instead of oxidizing atmosphere to heating in a controlled atmosphere with precise control of carbon potential and nitrogen potential. After heat treatment, the performance of parts is improved, and heat treatment defects such as oxidation, decarburization and cracks are greatly reduced. , The finishing allowance after heat treatment is reduced, which improves the utilization rate of materials and machining efficiency. Vacuum quenching, vacuum or low-pressure carburizing, nitriding, nitrocarburizing and boronizing can significantly improve the quality of the workpiece, reduce distortion and increase life.

Second, use new thermal insulation materials for energy-saving heat treatment to increase the energy efficiency of heat treatment equipment; optimize the heat treatment process, increase the process output, and give full play to the capabilities of the equipment. At this stage, various bearing manufacturers are doing experiments in this area, such as making full use of waste heat and waste heat. Some manufacturers have used forging waste heat to spheroidize and anneal bearing parts; low energy consumption and short cycle processes are used to replace long and high energy consumption. To a certain extent and within a certain range, the lower bainite quenching process has replaced the long-period and energy-consuming carburizing process with a shorter bainite quenching process.

Third, precision heat treatment is to fully ensure the stability of the optimized process, to achieve low (or zero) product quality dispersion, zero heat treatment distortion, reduce grinding allowance, improve production efficiency, and save materials. The realization of precision heat treatment must have good furnace temperature uniformity, temperature control accuracy, and good cooling and stability of the quenching agent.

Fourth, the waste water, waste gas, waste salt, waste oil and electromagnetic radiation formed by heat treatment production will pollute the environment. Solving the environmental pollution of heat treatment and implementing clean heat treatment is one of the development directions of heat treatment technology. This puts high demands on the heat treatment atmosphere, quenching oil and cleaning equipment.

Precautions for the selection of vacuum heat treatment furnace

First, when purchasing a vacuum heat treatment furnace, you must first understand what kind of electric furnace you need, and what parameters the electric furnace must have to meet the requirements.

Second, when purchasing a vacuum heat treatment furnace, you should also pay attention to the after-sales service of the product, because this is related to the repair and maintenance of the product in the later period. If the after-sales service cannot keep up, it will be a waste for consumers. A process of wasting energy and money.

Third, Shanghai Gehang Vacuum Technology Co., Ltd. is a manufacturer with more than 20 years of production, design, and manufacturing of vacuum heat treatment. It has rich experience. If necessary, please contact us in time.

If we want to participate in the heat treatment furnace industry, we must understand the development trend of the industry and understand the development requirements of the society. As long as the needs of the society are met, the industry will make progress, and we will also benefit from it.
