In recent years, laboratory analysis electric, domestic vacuum heat treatment furnace equipment and technology in the rapid development. China has developed a single-chamber pressure gas quenching vacuum furnace, convection heating and high pressure gas quenching vacuum furnace vacuum aluminum brazing furnace; foreign R & D of a gas vacuum furnace, semi-continuous and continuous vacuum furnace, fluidized vacuum furnace, multipurpose vacuum furnace high-temperature ultrahigh vacuum furnace, vacuum sintering furnace and vacuum furnace production lines. This paper briefly describes the above-mentioned equipment, and proposed the development trend of vacuum heat treatment furnace technology. In recent years, vacuum sintering furnace in working range, operating temperature and the amount of stove and the control technology aspects are new developments, industrial furnace used in stainless steel, tool steel sintering, carbide, ceramics, and other materials, money-iron-boron industrial application prospect. What is the future development trend of China's industrial furnace is? Development heat treatment using the latest procedures and databases, computer simulation technology and control technology, heat treatment furnace, a highly flexible, integrated intelligent control and management system for industrial furnace and production line. Future devices the operator only will the number of workpieces to be processed, the pattern entered into the computer, the entire device will handle their own high-quality products. We have achieved a real-time multi-project operation control of the entire system. The control loading capacity, speed, temperature, carbon potential, can achieve dynamic multi-group control system, furnace, full-screen monitor and control batch-feed. Can fully process control, you can store a number of processes. The recording apparatus can be fully detected operating conditions of process parameters (part number, material, temperature, atmosphere, etc.), processed and sent to the computer memory recording. Ready for viewing and printing. It can store ten records. Laboratory furnace | Longkou laboratory furnace (Online) | furnace experiments Longkou Furnace by.
