Box Type Multi-Purpose Furnace

Core Technologies And Processes

Heating: Preheating the workpiece to a high temperature to create the ideal temperature for carburizing.
 

Carburizing: In a controlled atmosphere (such as a carbon-containing gas), carbon is infiltrated into the workpiece surface, improving its hardness, wear resistance, and other properties. (Commonly used to strengthen mechanical parts such as gears and shafts.)
 

Quenching: Rapid cooling after carburizing creates a high-hardness martensitic structure on the workpiece surface, further enhancing its properties.

Structural And Functional Characteristics

Controlled Atmosphere Sealed Furnace: The furnace is tightly sealed to ensure a stable and controllable internal atmosphere (such as the carbon potential required for carburizing), preventing outside air interference and guaranteeing heat treatment quality.

Movable Trolley: Workpieces are automatically transported in and out of the furnace via a movable trolley, reducing manual labor and improving production efficiency and safety.

Multi-Process Integrated Design: Heating, carburizing, and quenching processes are integrated into the same equipment, eliminating workpiece transfers, minimizing heat loss, and reducing process errors.

Automation And Production Advantages

Highly automated: From workpiece loading, process execution, to unloading, the entire process is highly automated, simplifying operations and significantly reducing labor costs and human error.

 

Efficiency and quality assurance: Automated production improves processing efficiency. The controlled atmosphere and sealed furnace design effectively ensure consistent product quality. Strict process control further ensures production safety.

FAQ

1. What processes are box-type multi-purpose furnaces primarily used for?

They are primarily used for heat treatment processes such as carburizing, carbonitriding, bright hardening, and tempering, and can perform multiple processes continuously within the same furnace.

2. What is the function of the controlled atmosphere in this type of furnace?

Controlled atmosphere prevents oxidation and decarburization of the workpiece and enables precise control of the carburized layer depth and carbon concentration, ensuring a bright surface and stable performance.

3. What is the difference between a box-type multi-purpose furnace and a conventional box furnace?

Conventional box furnaces are typically only capable of heating or annealing, while a multi-purpose furnace can perform multiple processes, including heating, carburizing, and quenching, in a sealed atmosphere, making it a versatile machine.

4. What protective gases are used within the furnace?

Common gases include methanol decomposition gas, nitrogen, ammonia, or a nitrogen-methanol mixture to create a protective atmosphere or carburizing atmosphere.
