First, the use of scale for bearings, chains, pins, fasteners, small mechanical parts of shallow carburizing, carbonitriding, bright quenching.
Second, the basic composition of the feed organization, heating furnace, quenching tank, cleaning machine, tempering furnace and other components.
Third, the heating furnace layout features
1. Radiant tube heating; finish heating the workpiece on both sides; greatly improving the heating power and furnace temperature uniformity.
2, the use of lightweight impervious full fiber lining; than the anti-seepage brick lining power saving about 30%.
3, heat-resistant steel mesh belt driven by rotating rollers; reduce wear; improve service life.
4. The key components of the control are imported products; the overall reliability of the equipment is greatly improved.
5, for the safety of improved products; added a security alarm system and mechanical interlocking equipment.
6. The man-machine dialogue operation interface of the whole Chinese dialect; reflecting the full operating status of the equipment; various process parameters can be compiled and corrected.
Fourth, the quenching trough layout features
1. The quenching tank equipment has frequency conversion speed oil mixer; it can greatly reduce the quenching deformation of the workpiece.
2, high-power cooling can be air-cooled heat exchanger; improve the safety of equipment.
3. Closed leaker; reduce oxidation and decarburization of the workpiece.
4, with oil curtain; cut the soot into the heating room.
Five, clear machine layout features
1, double tank and two liquids to clear; there are liquid level alarm and active rehydration equipment.
2, special oil and water separator; rotary spray nozzle; good scrubbing effect.
3, clear the end into the electric drying room for drying.
Sixth, tempering furnace equipment features
1. The top is pierced into the cluster type electric heating tube; it is durable and convenient to protect.
2. The mesh belt is tumbled on the rail plane; the service life is improved.
3. Equipment has exhaust pipe and oil water discharge pipe; reduce environmental pollution and improve product quality.
4, equipped with digital PID temperature controller; high precision control
