Equipment Usage

HanKou Electric Furnace Co. develops and produces vacuum variable pressure low-temperature carburizing furnaces. This series of products can perform ultra-low temperature carburizing on precision parts like stainless steel precision valve tips and washers at temperatures below 500°C, effectively reducing issues such as carburization deformation in components.

Primarily used for carbon nitriding of metallic materials to enhance surface hardness, wear resistance, and fatigue strength. This equipment integrates vacuum and variable pressure technologies, enabling an efficient carbon nitriding process at lower temperatures.

Configuration Features

1. Vacuum Environment: Carbon nitriding in a vacuum environment effectively removes oxides and other impurities from the workpiece surface, ensuring the quality of the carbonitriding layer.

2. Low Temperature Treatment: Compared to traditional high-temperature carburization, the vacuum pressure carburizing furnace can perform carburization at lower temperatures (typically between 500°C to 900°C), thereby reducing issues such as workpiece deformation and grain coarsening.

3. Precise Temperature Control: Equipped with a high-precision temperature control system, it ensures accurate control of the furnace temperature, guaranteeing consistency and repeatability in the carburization process.

4. Uniform Heating: Optimized heating element layout and hot air circulation system ensure uniform temperature distribution within the furnace, resulting in consistent carburization effects.

5. Atmosphere Control: Precisely controls the gas composition and pressure within the furnace for optimal carburization effects.

6. Voltage Transformation Technology: By adjusting the furnace pressure, the activity of the carbon diffusion agent can be changed, thereby enhancing the carbon diffusion efficiency and uniformity of the carbon diffusion layer.

7. Automated Operation: Equipped with advanced automated control systems, it can achieve automatic control of the entire carburizing process, including setting and monitoring of parameters such as temperature, pressure, time, and gas flow rate.

8. Safety and Reliability: Equipped with multiple safety protection devices, such as over-temperature alarms, over-pressure protection, and leakage protection, ensuring the safety and reliability of operation.
