30kw Nitriding Furnace

nitriding furnace is used for nitriding process of aluminium or steel dies under low varying vacuum with china invention patent

our vacuum varying pressure Nitriding furnace has won China invention patent and sold in 56countries in the world, each year, more than 100  sets have spread around the world.

Nitriding process of this furnace is finished under low vacuum condition, and the automatic pressure change and ventilation can guarantee the inside atmosphere fresh, active, quick diffusing and uniform at every corner of the furnace. This type of furnace has good sealing, is an environmental protection product as waste gases can be exhausted from the sealed water tank after being pumped by vacuum pump and treated there.Advantages of this product (take aluminum mode H13 as an example)1. Quick diffusing rate2. Heat-preservation time: 8-10 hours, diffusing layer depth: 0.14~0.18mm, white layer: 0.006~0.01mmHV1000~1200The surface hardness can reach HV1000~12003. Large loaded-amount, low procession cost4. Surface friction coefficient is small5. Low brittleness 6. Stable performanceThe furnace atmosphere and temperature are uniform and controllable, assuring the process stability and improving the quality of working nitriding.7. Easy for operationWhen the furnace is working, the inner pressure presents periodical change, so does the nitrogen potential, which allows one segment of nitride to replace two or even three segments, simplifying the process and the operation is simpler as one furnace can replace 4-5 sets.8. Wide adaptability, uniform diffusion layer
