·The RG series production Line consists of an entirely spiral cylindrical tumbling box and a fully automatic operation system. The structural design is appropriate and innovative.

·The RG series production Line is suitable for the polish-quenching and shallow carburizing quenching of steel balls, rollers and standardized workpiece.

·The quenching oil tank consists of two tumbling boxes. One tumbling box has its frequency controllable and the other box transfers the workpieces steadily, which allows the workpieces to have uniform hardness and excellent internal structure.

·The frequency of the tumbling box is steplessly adjustable; the system is able to control the amount of incoming material accurately. The heating process is very uniform and stable.

·Radiant tubes are used as the heating system, which has long life-time and can be conveniently repaired.

·The temperature control system employs a modularized non-contact and non-surge SCR control technology to realize a steady heating and a high precision of temperature control.

·The temperature, the electricity and the atmosphere of the furnace can be automatically controlled by computer.

·The production line has a consummate chained-lock system and an optical-sound alarm function.
