System control of stainless steel mesh belt furnace

        Equipment temperature control: furnace temperature stability ±1℃, trolley furnace temperature uniformity ±10℃, cold treatment temperature uniformity ±5℃, switch temperature control will be eliminated.


   Furnace atmosphere control: the furnace atmosphere uniformity 0.05% oxygen probe, decarbonization air pump, carbon potential controller, furnace gas regulator can be reliably matched on the mesh belt furnace. Suitable for nitrogen methanol atmosphere. Methanol acetone (toluene) atmosphere, endothermic atmosphere, exothermic atmosphere, etc.

The development of the combined multi-element carbon potential control technology of oxygen probe and infrared meter and the emergence of other new carbon potential control technologies can not only improve the accuracy and stability of carbon potential control, but also better adapt to the atmosphere prepared by various gas sources . Further optimization of the quality control of carburizing and carbonitriding layers by the carbon potential control technology of the second zone of the double oxygen probe.

  

        Continuous mesh belt furnace water quenching to eliminate water vapor device appeared to stabilize the furnace atmosphere and ensure the accuracy of carbon potential control carburizing furnace. The new development of methanol gasification and cracking technology and the widespread use of stirring fans in the furnace have further improved the uniformity of the atmosphere in the furnace. The furnace shell sealing welding method not only saves energy, but also contributes to the long-term stability of the furnace atmosphere.


        Quenching tank control: In terms of ensuring the uniformity of workpiece hardness and reducing part deformation, it has developed from simply reducing the cooling rate in the past to improving cooling uniformity. The quenching tank is equipped with an adjustable speed and powerful agitator, and the flow field of the quenching tank is emphasized. Tank temperature uniformity. The temperature of the quenching tank is controllable. The computer cooling medium performance tester is also accepted by many users.


        Dryer Heat treatment distortion control; use the quenching furnace to lengthen the hot zone to remove stress. It adopts a fully enclosed oil tank with heat preservation and controllable graded quenching. The temperature uniformity of quenching medium is 5℃. The anti-collision design of the quenching tank and the blanking system of the elevator. In order to reduce the amount of retained austenite of bearing parts and control the slight deformation after bearing processing, the mesh belt furnace production line will add a cold treatment device after quenching.
