LDMCF-30/15AZ Plasma Lon Nitriding Furnace With Auxiliary Heating

What is auxiliary heating?

ion nitriding furnaces, the heating of workpieces relies entirelyon the heat generated by the plasma bombarding the surface of the workpieces.This approach is "from the surface to the core".

The auxiliary heating system is a set of heating devices (usually resistanceheating rods or heating plates) independently installed in the vacuum furnace body.It can radiate heat the workpiece before, during or independently of the plasmastartup.

In simple terms, it is equivalent to installing an "electric furnace" inside theion nitriding furnace, achieving dual or independent heating of the workpiece.

Application：

As an effective steel and alloy surface strengthening technology, ion nitriding has been widely used in the industrial field. Ion nitriding is different from traditional gas nitriding. Ion nitriding is mainly used for surface normalizing, quenching and tempering and ion nitriding treatment of alloy structural steel, bearing steel, spring steel, die steel, tool steel and other materials.

Core Features

1. 1.Coordinated Temperature Control with Dual Heat Sources

   The equipment is equipped with plasma glow discharge heating and an independent auxiliary heating module. It can not only realize nitriding reaction on the workpiece surface by means of plasma, but also quickly raise the overall temperature in the furnace and reduce the temperature difference in the furnace cavity through auxiliary heating. It achieves precise temperature control in a wide range of 50℃-900℃ with a temperature control accuracy of ±3℃, meeting the differentiated heat treatment process requirements of workpieces of different materials.

3. 2.High-Efficiency Nitriding Modification Effect

   The furnace adopts a closed vacuum chamber design, combined with an accurate nitrogen/hydrogen mixed atmosphere control system, which can form a uniform and dense nitriding layer on the workpiece surface. The thickness of the nitriding layer can be controlled between 0.01mm-0.5mm, which significantly improves the wear resistance, corrosion resistance and fatigue resistance of the workpiece and extends the service life of the workpiece by 3-5 times.

1. 3.Intelligent and Precise Control

   It is equipped with a fully automatic PLC control system and a touch operation screen, which can preset process parameters such as nitriding temperature, holding time, and atmosphere ratio, and support real-time display of process curves and data storage and traceability. At the same time, it is equipped with multiple safety protection devices such as over-temperature alarm and vacuum degree abnormality warning to ensure stable operation and operation safety of the equipment.

3. 4.Adaptation to Diverse Working Conditions

   The furnace cavity specifications can be customized (from φ300×400mm small cavity to φ1200×1500mm large cavity), which can not only meet the small-batch sample research and development in the laboratory, but also adapt to large-scale production in factories. The equipment is also equipped with a rapid cooling module, which can shorten the workpiece cooling cycle and improve the overall production efficiency.

5. 5.Energy-Saving and Environmentally Friendly Design

   The furnace body adopts a multi-layer thermal insulation structure with heat loss as low as below 8%. The auxiliary heating module can be intelligently started and stopped according to process requirements, saving 15%-20% energy compared with traditional plasma nitriding furnaces. It has no open flame and no exhaust gas emission, complying with industrial green production standards.
