Introduction to the characteristics of box carburizing furnace

In order to shorten the nitriding cycle and make the nitriding process not limited by steel, two new nitriding processes, soft nitriding and ion nitriding, have been developed on the basis of the original nitriding process in recent years. This is also the price of the nitriding furnace. s reason.

Nitriding soft nitriding is basically based on soft nitriding low temperature, nitrogen atoms, and the penetration of steel, the number of carbon atoms is small, compared with the general results of processing gas nitriding, the layer hardness is milder than nitrogen, not too brittle, This is the so-called soft nitriding treatment.

Nitriding furnace is a device with direct nitriding technology, which has the characteristics of low working temperature, short time, small deformation of workpiece, high fatigue strength limit and good wear resistance. Nitriding time treatment refers to a chemical research heat treatment production process that causes nitrogen atoms to penetrate into the surface of the workpiece in a certain influence medium at a certain ambient temperature. Nitrided products have excellent wear resistance, fatigue resistance, corrosion resistance and high temperature resistance.

The stainless steel vacuum nitriding furnace is heated to 520 ℃ with the ammonia gas in the sealed tank, and the temperature is maintained for an appropriate time according to the claim 3-90 hours and the diffusion layer is obtained from the surface of the workpiece to obtain nitrogen-containing nitriding workpiece material replenishment. Strong layer, high hardness, high wear resistance, high fatigue limit and good wear resistance.

The price level of nitriding multi-purpose furnace is uneven, and it is also affected by the market operating system process. Next, let's take a look at the operation management process of the nitriding furnace:

Nitriding multi-purpose furnace has the characteristics of low processing temperature, short time and small deformation of workpiece. Performance: high fatigue limit, good wear resistance.

Before nitriding 1. The gas nitriding furnace must be a workpiece that has been normalized or tempered..

2. First use traditional gasoline and alcohol to scrub the gas through the surface of the workpiece material of the nitriding furnace, and there must be no rust spots, oil stains, and dirt.

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

4. The furnace cover and the tank inlet enter the water for cooling water circulation. The cooling water pipe cover flows into the lower end of the gas nitriding furnace, water, separate tank furnace water, independent drainage, and the upper end of the gas nitriding furnace cover principle. All water can be in a series of low to high, through one inlet and one discharge.

5. Before heating up the nitriding furnace, nitrogen should be sent through the exhaust, and the flow rate should be more than double that of us when exhausting.
