Pit Type Controlled Nitriding Furnace

Pit type controlled nitriding furnace details Application This is a series of batch-type pit-type controlled nitriding furnaces and isused for the nitriding of metallic dies and tolls, shafts, gears, etc. if it is equipped with KRN-W or WPB-N series controlling cabinet, the nitriding atmosphere, temperature, operating time, and gas and flow liquid can be controlled automatically. This series can also be used for variousapplicationincluding soft-nitriding, tempering, stress relieving of steel parts, as well as the solution treatment of nonferrous metals. Features 1. This series is furnished with a KRN-W micro-processor controlled nitrogen potential micro-processor,itmeasures, adjusts and records for nitrogen potential, temperature, time, gas and water flow can be performed automatically; 2. The unique doubly insulated furnace and circulating fan mechanims allows nitrogen potential uniformity better than ±0.1%, and internal pressure greater than 250 mm H2O.3. The advanced ceramic tile lining greatly insulates the furnace, significantly speeding heating and thereby saving up to 20% in energy usage.4. The rapid-cooling fan system shortens the production period greatly.5. A vacuum system can be fitted for controlled pulse-nitriding.
