   RN-90-6 Low Temperature Electric Nitriding Furnace Vacuum Atmosphere Controll

Introduction of electric nitriding furnace:

Pit type gas nitriding furnace is mainly used for carbon steel parts gas nitriding, mould quenching and other heat treatment . The furnace is equipped with drip device, also can be used for gas nitrocarburizing (soft nitriding) heat treatment. When doesn’t feed into ammonia gas and use drip devices, can be used as a general well type tempering furnace.


Electric nitriding furnace features:

1. The rate of seepage is fast .

The nitriding process is to perform periodic pressure change in the furnace under low vacuum conditions. The atmosphere is kept fresh and active, and the nitrogen potential is also cyclically changed, so that one-stage nitriding has the advantages of two-stage and three-stage nitriding, and it is not necessary to adopt two or three. Segment nitriding, speeding up nitriding

2. Wide adaptability and uniform permeability .

The workpiece has a blind space, a T-shaped surface or a workpiece working surface in a very narrow slit. For a conventional positive pressure nitriding furnace, this is not conducive to the replacement and diffusion of the fresh atmosphere, and the nitriding effect of these parts is not ideal. The low vacuum pressure transformation technology allows the furnace gas to automatically diffuse into the tank, without dead ends. Blind holes, pores, and working faces at the die slits also provide the desired layer.



More about our well type furnace

1. Use for heat treatment in air of steel parts especially the long pieces .When the process requires, may pass into the protective atmosphere to reduce oxidation of the workpiece.

2. one area control ,using intelligent digital display instrument with silicon controlled temperature control, also have heat preservation time relay, with the function of over temperature alarm.

3. The heating element is 0Cr21Al6Nb heating filament.

4. Lining by energy-saving light and aluminum silicate refractory fiber and diatomite brick.

5. Furnace cover open by leverage.

6. Equipped with heat resistant steel skirts in the middle.
