1. Scope of application
It is used for shallow carburizing, carbonitriding and bright quenching of bearings, chains, pins, fasteners and small mechanical parts.
2. Basic composition
It is composed of feeding mechanism, heating furnace, quenching tank, cleaning machine, tempering furnace, etc.
3. Structural characteristics of heating furnace
1. The radiant tube heating realizes heating on both sides of the workpiece, which greatly improves the heating efficiency and furnace temperature uniformity.
2. The lightweight impermeable full fiber lining is adopted, which saves about 30% of electricity than the impermeable brick lining.
3. The heat-resistant steel mesh belt is driven by a rotating idler to reduce wear and improve service life.
4. The key control components are imported products, and the overall reliability of the equipment is greatly improved.
5. In order to improve product safety, a safety alarm system and a mechanical interlocking device are added.
6. The man-machine dialogue operation interface in full Chinese can reflect the entire operating status of the equipment, and can compile and modify various process parameters.
4. Structural characteristics of quenching tank
1. The quenching tank is equipped with a variable frequency speed regulating oil stirrer, which can greatly reduce the quenching deformation of the workpiece.
2. The air-cooled heat exchanger with high-power cooling capacity improves the safety of the equipment.
3. The closed leaker reduces the oxidation and decarburization of the workpiece.
4. Use the oil curtain to reduce the oil fume entering the heating chamber.
5. Structural characteristics of cleaning machine
1. Double tank and double liquid separation and cleaning, and has liquid level alarm and automatic liquid replenishment device.
2. Special oil-water separator, rotary spray nozzle, good washing effect.
3. After cleaning, enter the electric heating drying room for drying.
Six, tempering furnace equipment characteristics
1. The top is inserted into the cluster electric heating tube, which is durable. Easy to maintain.
2. The mesh belt rolls on the rail plane to improve the service life.
3. A discharge pipe for waste gas and oil and water is installed to reduce environmental pollution and improve product quality.
4. Equipped with digital PID temperature controller, high control accuracy
