Products Name:GTR series Roller-hearth Tempering Production line
 
 
    Product description

 ·This product is very suitable for tempering treatment on large hardware such as large bearings on wind power plant.

·The transmission is performed using roller only on the production line. The transmission is very steady during the hardening heating, the quenching and the tempering. The deviation of the quality of the workpieces.

·The quenching slot is filled with water based solution. A roller-hearthed elevator is installed in the quenching slot. The elevator is able to fluctuate with controllable frequency around 15-20times/min. The hardness and deformation of the workpieces after quenching are very good.

·The cooling of the quenching liquid is performed using air-cooling fans, which guarantees the temperature of the quenching liquid is well controlled.

·The radiant tube on the production line is manufactured from imported heat resistant seamless steel pipes, the employment of the thyristor enabled the control of power and voltage, greatly extended the life-time of the radiant tubes, and reduced the chance of malfunction.

·Several fans are installed inside the lid of the tempering furnace. These fans stir the air effectually, which greatly stabilized the temperature, to equalize the heating process of each workpieces.
