Batch Gas Nitriding
The Almor Batch Gas Nitriding Furnace is based on the well proven Wild Barfield design. Over many years Wild Barfield has established a reputation for the supply of robust installations to meet a wide variety of gas nitriding and nitrocarburising needs for a diverse range of industries:
Design Features
- Vertical loading
- Fixed or removable sealed nickel chromium retort
- Gas nitriding, ferritic and austenitic nitrocarburising
- Maximum temperatures up to 800ºC
- Lid mounted fan and baffle for optimum atmosphere uniformity
- Low thermal mass insulation
- Excellent temperature uniformity (+/- 6ºC 400 – 800ºC – electric version)
- Ammonia, Nitrogen / ammonia, Endothermic gas/ ammonia or other gas mixes
- Advanced process control systems for optimum control of nitriding potential
Standard Designs
- Electrically heated
- Charge space – up to 1,575 mm deep – up to 400 mm diameter
