        RQ3-90-9 Well Type Low Carbon Steel Gas Carburizing Electric Furnace

Characters of steel gas carburizing furnace:

The high temperature controlled gas carburizing furnace, mainly be used for protective atmosphere carburizing, quenching. Suitable for variety of workpieces carburizing, carbonitriding infiltration , multicomponent permeation heat treatment process.


Main Performance Index of carburizing furnace:
1.1 carbon potential uniformity: ≤±0.05%CP;
1.2 carbon potential stability: ≤±0.02%CP;
1.3 carbide uniformity grade: ≤±1 grade;
1.4 Effective case depth tolerance: ≤±0.1mm for case depth≤1mm; ±5% for case depth: ≥1mm; (same bath material);
1.5 carbon potential control method: oxygen probe and PID regulation;


Parts Description of steel carburizing furnace:
1), Shell:made by steel plate and structural steel.
2), Inside of furnace cover: made by stainless steel plate.
3), Burner liner: using the super light and energy conservation micropore fire-resistant heat reserving brick
4), Aluminum silicate fiber at between burner liner and shell, and also fill full of thermo-insulating power in gap.
5), Resistance wire: use the 0Cr25Al5 high resistor alloy wire installed upon brick.
6), Furnace cover: use the manual lever lifter or motor-driven or hydraulic.

7) , We have installed fan which made by a heat-resistance stainless steel shaft and fan blade for uniform heating the work-piece
8), Limit switch installed near the lifter device for safety operation.

Characteristics of gas carburizing furnace:

1) Rational structure, uniform furnace temperature, small upper & lower temperature difference in working zone, especially applicable for heating and heat treatment for long axial work-piece.

2) Adopt energy-saving furnace lining, fast temperature rise, low empty furnace consumption, save more than 20% of energy compare with old product.

3) The control system can be equipped with normal control instrument or instrument with micro-processor program control according to actual need.

4) When needed during process, protective atmosphere can be fed into the furnace to realize little-oxidizing heating.

5) Each product is installed with safety interlock and over-temperature device to provide reliable and safe operation and use.
