Product Description

Continuous heat treatment furnace for screw / nail hardening and quenching
 

1. RGR Series Rotary electric furnace(Quenching/Hardening furnace)
 

Function:

The furnace is mainly used for gas carburizing, gas carbonitriding and bright
quenching & heating small parts with different shape, such as nails, screws, steel balls, bushins, pins, tapping screws, standard parts, chains are made of high-speed tool steel, die steel, martensitic stainless steel, titanium alloy and such metal materials.
 

Features:

1).This furnace is heated by resistance, controlled by solid state relay and intelligent instrument of Japan conductive company, and using PID adjusting method, has the advantages of accurate temperature control, simple operation, stable performance.
2).Working zone uses sealed cylinder-shaped chamber furnace made of imported high temperature stainless steel,it rotates automatically after the workpieces are putting into the furnace chamber to make the workpieces be heated uniformly. It can also be passed into various gas to meet various technological requirements of workpieces.
3).The furnace body is supported by a bracket, can tilt upward or downward under the control of tilt unit, and can discharge automatically when it's tilting downward.
