650 Degree Steel Alloy Nitriding Machine Of Steel Bar

Nitriding Furnace Of Steel Nitriding Furnace Of Steel Alloy Nitriding Furnace Of Steel Bar

Ion nitridation process flow

1.Workpiece preparation

2.Place the workpiece on the workbench and close the furnace

3.Vacuum to 10mpa

4.Add voltage 400-600V

5.When the workpiece is heated to 100℃, add nitrogen and hydrogen (the amount of gas introduced is 801/h), and then rise the temperature to 520℃

6.Nitrogen atoms partially penetrate into the workpiece under the acceleration of the electric field, and hydrogen atoms combine with trace oxygen atoms to form water

7.The nitrogen atoms that are not involved are combined into nitrogen molecules, the hydrogen atoms that are not involved are combined into hydrogen molecules, the hydrogen atoms are combined with a trace amount of oxygen atoms to form water, and the three mixed gases are discharged from the furnace body through a vacuum pump

8.After 8-10 hours of heat preservation at 520 ℃, turn off the gas supply, turn off the vacuum pump, turn off the power supply, and the workpiece cools with the furnace

9.When the temperature of the workpiece drops below 200℃ , put air into the furnace to make the furnace reach atmospheric pressure, lift the furnace body, take out the workpiece, and finish nitriding.
