using a ZeroFlow® method

Gas nitriding using a ZeroFlow® method SECO/WARWICK in cooperation with Professor Leszek Małdziński from the Institute of Work Machines and Vehicles of the Technical University in Poznan has developed a new method of controlled gas nitriding and nitrocarburizing - ZeroFlow®. In the gas nitriding methods, used so far, the process based upon the adjusted double-component atmospheres NH3 + NH3 dissociated and NH3 + N2 is used. “Even though nitriding of steel can be considered a by-product of the dissociation of ammonia, there is no need to dissociate more ammonia than absolutely necessary....

Save your time, save your money, let ZeroFlow® improve your nitriding Examples of parts nitrided with use of ZeroFlow® method Nitriding of plates for casting glass bulbs for lamps Nitriding of inlet sleeves with the pushing piston, used in molds for aluminium pressure die casting Nitriding of crankshafts for engines of racing cars Nitriding of toothed wheels for wind power plants Nitrocarburizing and post-nitrocarburizing oxidation of shafts Nitrocarburizing of piston rods in the automotive industry Comparison of consumption of NH3 and N2 in the traditional processes and ZeroFlow® during...

Control system properties □ All executive and measurement elements are reflected in the control system (PLC, SCADA), allowing for fully automatic diagnostics and localization of any machine operation anomalies □ Possibility of recording unlimited number of recipes, created by the process engineer □ All process data, presented as diagrams on the screen may be stored on the external hard disk or CD □ Possibility of exporting the historical and alarm data out of the system for further analysis (e.g. to .csv files) □ Logging of the most important historical data in files and/or any data base of...

Save your time, save your money, let ZeroFlow® improve your nitriding The program as a result of simulation provides information on the obtained phase structure, surface hardness, hardness layout and effective depth according to defined criteria. At present we work on next versions that will enable to program desired results, where the simulator will be responsible for determination of parameters that will ensure those results As an element of SECO/WARWICK furnaces control systems, the simulator will transmit a recipe directly to the furnace's controller to enable process start-up...

The nitriding technology with ZeroFlow® method is based upon many years of research/trials and tests, documented and published in prestigious magazines about thermal processing. They have been created by the eminent professionals from the science world and employees of SECO/WARWICK For more information, results and documentation: www.secowarwick.com Furnaces for gas nitriding We use two basic types of furnaces for realization of adjusted gas nitriding: with the horizontal retort – type HRN and with the vertical retort (pit) – type VRN. The useful dimensions of the furnace chamber, load...
