What is the operation process of the carburizing Multi-purpose furnace?

The prices of carburizing furnaces vary greatly and are also affected by the operation process. Next, let's take a look at what the operation process of the Carburizing multi-purpose furnace is like. The nitriding furnace features low processing temperature, short processing time and small workpiece deformation. Properties: high fatigue limit and good wear resistance.

The gas nitriding furnace before nitriding must be for workpieces that have undergone normalizing or quenching and tempering treatment first.

2. First, wipe the surface of the workpieces in the gas nitriding furnace with gasoline and alcohol. There must be no rust spots, oil stains or dirt.

3. After loading into the furnace, tighten the furnace cover clamping bolts symmetrically.

4. Introduce cooling water into the water inlets of the furnace tank and the furnace cover for circulating water cooling. The lower end of the cooling water pipe on the cover of the gas nitriding furnace is for water inflow and the upper end for water outflow. The furnace tank takes in water and discharges water separately. All the water pipes on the cover of the gas nitriding furnace can be connected in series according to the principle of low in and high out, with water inflow from one outlet and water outflow from the other.

5. Before heating up the gas nitriding furnace, nitrogen should be sent for exhaust first. The flow rate during exhaust should be more than twice as large as that during use. After 10 minutes of exhaust, set the temperature control instrument to 150℃, turn the automatic heating switch to the on position, and keep the gas nitriding furnace heating at 150℃ for 2 hours while venting. Then set the temperature control instrument to 530℃, reduce the ammonia flow rate, maintain positive pressure inside the furnace, and have a small upward pressure of the gas flow at the exhaust port. When the furnace temperature rises to 530℃, carry out constant temperature and flow nitriding for 3 to 20 hours. Increase the ammonia pressure a little more to maintain a moderate exhaust pressure, carry out nitriding for 4 to 70 hours, then reduce the ammonia pressure, perform denitrification for 1 to 2 hours, cut off the power supply, and provide a small amount of ammonia.
