Detailed Description

Controlled Atmosphere Bell-Type Nitriding Furnace

Controlled Atmosphere Nitriding Furnaces are divided into: box-type nitriding furnaces, pit-type nitriding furnaces and bell-type nitriding furnaces, which are mainly used for traditional nitriding or nitrocarburizing of workpieces such as gears, shafts, crankshafts, molds, etc., to improve the wear resistance and fatigue resistance of the workpiece surface and extend the service life of the workpiece.

Features of nitriding furnace:
1. The furnace tank, air guide tube and furnace internal components are made of 310S (0Cr25Ni20) heat-resistant steel material, so that the nitriding process is stable and has a long service life.
2. The streamlined furnace body surface design makes the equipment look generous and can be personalized according to customer requirements.
3. The German high-end integrated controller (PE or STANGE), hydrogen probe and high-precision flow control valve are used for control, and the nitrogen potential is used as the control unit. The control method is advanced, the operation is reliable, the interface is friendly, and it is easy to use.
4. The upper computer system connected to the integrated controller has the functions of process program compilation, process dynamic control, equipment operation status display, process curve chart recording, equipment alarm display and recording, etc.
5. You can also choose the nitriding control system independently developed by our company, that is, using a hydrogen probe to measure hydrogen and using nitrogen potential as a control variable to control the entry of ammonia and ammonia decomposition gas. All ammonia and ammonia decomposition gases in the furnace are controlled by mass flow meters. Under the premise of high control accuracy, the equipment investment cost is reduced, which is suitable for use by mid-to-high-end customers.
6. It has an automatic exhaust gas emission and combustion system to make the working environment pollution-free.
7. According to the size, process and output of the customer's heat treatment products, the equipment can be developed to realize traditional nitriding, nitrocarburizing, pre-oxidation and post-oxidation processes to meet the needs of different customers.

Controlled Atmosphere Nitriding Furnace FAQ

What is a Controlled Atmosphere Nitriding Furnace and what are its main functions?
A Controlled atmosphere nitriding furnace is a high-temperature furnace used for nitriding of metal materials, mainly used to improve the hardness and corrosion resistance of steel surfaces. A nitriding layer is formed by penetrating nitrogen atoms into the metal surface under a controlled atmosphere (usually ammonia or nitrogen mixed gas). This layer can significantly improve the wear resistance, hardness and fatigue strength of the workpiece, and is widely used in industries such as automobiles and mechanical parts.

What is the working principle of a Controlled atmosphere nitriding furnace?
A Controlled atmosphere nitriding furnace introduces a nitrogen source gas (such as ammonia) into the furnace at a high temperature (usually 500°C to 550°C) by heating the workpiece in a specific atmosphere. Under atmosphere control, ammonia decomposes into nitrogen atoms, penetrates into the metal surface, and forms a uniform nitriding layer. The nitriding layer not only improves the surface hardness of the workpiece, but also improves its corrosion resistance and fatigue resistance, thereby increasing its service life.

How to maintain a Controlled atmosphere nitriding furnace?
In order to ensure the stable operation of the Controlled atmosphere nitriding furnace, regular inspection and maintenance are required. First, clean the furnace to remove residual nitrides and impurities to prevent pollutants from affecting the treatment effect. Secondly, regularly check the gas system, including ammonia supply and gas flow control, to ensure a stable atmosphere. Also check the temperature control system to ensure that the temperature is accurately controlled. Finally, regularly check the heating elements and sealing systems to ensure that they function properly to avoid gas leaks or temperature fluctuations.
