The SY-805-4 conveyorized belt furnace is a high-performance continuous belt carburizing furnace production line developed by Taiwan's SanYong Electric Heat Machinery Co., Ltd. The line not only features excellent sealability with multi-level labyrinth seals and flexible graphite gaskets to effectively prevent atmosphere leakage, but also is equipped with an advanced integrated control system for atmosphere composition, furnace temperature uniformity, and key process parameters. It also offers comprehensive real-time monitoring of equipment operation status, automatic fault diagnosis and alarm, as well as the capability to trace historical process parameters. In recent years, as one of the key heat treatment equipment for development, the continuous belt carburizing furnace has seen increasing applications across various industries including automotive, aerospace, and mechanical manufacturing. According to forecasts by industry authorities, during the "Fifteenth Five-Year Plan" period, China's mechanical base parts industry is expected to exceed a demand of over 100 conveyorized belt furnace production lines annually, indicating significant market potential and a promising development outlook.
