A carburizing furnace is a new type of energy-saving, batch-type heat treatment electric furnace. It uses either natural gas or electric heating as its heat source and is primarily used for surface carburizing of metal workpieces. It allows for precise control of carbon element penetration to improve surface hardness, wear resistance, and corrosion resistance, while maintaining the toughness of the workpiece core. It is suitable for heat treatment processes in the metallurgical and machinery manufacturing fields. The equipment is divided into two types: intermittent and continuous. The push-rod type furnace features four temperature control zones: heating, carburizing, diffusion, and cooling.

Principle and Types of Carburizing Furnaces
Principle: The working principle of a carburizing furnace is to heat low-carbon or medium-carbon steel parts to a certain temperature (generally 900℃-950℃) and maintain them in an atmosphere containing active carbon atoms, allowing carbon atoms to gradually penetrate the surface of the steel, forming a high-carbon layer of a certain thickness. Subsequently, through subsequent heat treatment processes such as quenching and low-temperature tempering, the surface layer acquires high hardness and wear resistance, while the core maintains good toughness.
Types:Common types of carburizing furnaces include pit-type carburizing furnaces and continuous carburizing furnaces. A pit-type carburizing furnace is a batch-type heat treatment electric furnace, mainly composed of a furnace shell, furnace lining, furnace cover lifting mechanism, furnace sealing fan, muffle furnace, heating elements, and electrical control system. Continuous carburizing furnaces include pusher-type furnaces, rotary drum furnaces, vibrating hearth furnaces, and mesh belt furnaces. These furnace types can achieve continuous production and improve production efficiency.
Advantages of Industrial Carburizing Furnace in Improving Workpiece Performance
Improved Workpiece Performance: Workpieces treated in a carburizing furnace exhibit significantly increased surface hardness, as well as greatly enhanced wear resistance and fatigue strength. This makes them suitable for manufacturing various mechanical parts that withstand high loads and wear.
Energy Saving and Environmental Protection: Modern carburizing furnaces utilize advanced energy-saving technologies and materials, such as ultra-lightweight energy-saving furnace lining materials and integrated water-cooled furnace sealing fans, effectively reducing energy consumption.
High Degree of Automation: Continuous carburizing furnaces are equipped with automated control systems, enabling automated operation of processes such as loading, heating, carburizing, and quenching, thereby improving production efficiency and product quality.

Carburizing furnaces are widely used in automotive manufacturing, mechanical processing, aerospace, and other fields. For example, in the automotive industry, carburizing furnaces are used to treat transmission gears, shafts, and other parts to improve their wear resistance and service life. In the mechanical processing industry, carburizing furnaces can be used to manufacture various high-strength, high-precision mechanical parts.
Gas Carburizing Furnace Operating Procedures and Maintenance
Operating Procedures:
● Before starting the furnace, preparatory work must be completed, such as cleaning carbon deposits from the furnace chamber and checking components such as the sealing gasket, circulating fan, and motor.
● When starting the furnace, follow the prescribed operating procedures, such as adjusting the automatic control device, starting the fan during heating, and beginning to drip kerosene or methanol after the furnace temperature reaches a certain level.
Maintenance:
● Regularly inspect and maintain all components of the carburizing furnace, such as heating elements, furnace lining, and furnace lid lifting mechanism, to ensure their normal operation.
● Pay attention to controlling the furnace atmosphere, maintaining the uniformity and stability of the carbon potential atmosphere.
