The reduction furnace is mainly used for semiconductor, nano, light materials, copper powder, cobalt powder, nickel powder, tungsten powder, molybdenum powder, tungsten powder and other complex processes. Under the protection of various gases, the material is fully mixed with hydrogen, and the temperature is reduced through the gas protection to control the flow of various process gases. It is an important equipment for scientific research, teaching, production and research and development of new materials, and is widely used in chemical, electronic, metallurgical, energy and other industries.

 

 

Introduction of reduction furnace:

1. The material can be fully mixed with hydrogen, which can shorten the reduction time of the material and save a lot of hydrogen (because the hydrogen is fully mixed with the material).

2. After the material is reduced, it can be cooled quickly or slowly in different atmospheres according to the characteristics of the material.

3. Industrial microcomputers are used to automatically control processing time, temperature, gas flow rate, valve action and reaction chamber pressure.

4. Inlet pressure control system, closed loop control, high stability.

5. Imported corrosion-resistant stainless steel pipe fittings and valves are used to ensure the air tightness of the gas path.

6. With perfect alarm function and safety interlocking device.

7. Good man-machine interface and flexible process performance.

 

The characteristics of reduction furnace:

1, the product output is large, good quality:

The powder is directly and evenly distributed on the steel strip, which effectively uses the space in the furnace;

The material passes through the heating zone evenly, and the process adjustment of temperature and belt speed is simple and convenient;

2. Low energy consumption:

The whole fiber needle felt module has good heat insulation effect, low energy storage and low heat loss;

3. Long service life of furnace tube;

Furnace tube prestressing device, at the same time, the bottom pad with high strength, low friction coefficient, high temperature resistant silicon carbide plate, to ensure the smooth expansion and deformation of metal furnace tube at high temperature, the service life of similar products increased by 1.3 times;

4. High degree of equipment automation:

Automatic temperature and motion control, perfect alarm and lock protection device.

 

In summary, the characteristics of the reduction furnace is in a given temperature, to the furnace into a certain composition of the artificial preparation of the atmosphere, in order to achieve the purpose of a certain heat treatment, such as gas carburizing, carbon nitrogen co-penetration and bright quenching, annealing, positive fire and so on. The main purpose of the reduction furnace is to maintain a certain carbon potential in the furnace. In addition to controlling the stability of the atmosphere composition, the atmosphere in the furnace must be continuously or regularly measured and adjusted.

 

In order to control the atmosphere in the furnace and maintain the pressure in the furnace, the working space must always be isolated from the outside air, and try to avoid air leakage and air inhalation. The atmosphere reduction furnace is automatically controlled. Therefore, it is necessary to provide various control instruments for continuously or periodically measuring and adjusting the amount of air supply in the furnace. All kinds of reduction furnace sealing requirements are high, loading and unloading operations are complex, requiring a furnace multi-use. In mass production, many large-scale combined heat treatment special or dual-purpose units are formed, so a higher degree of mechanization and automation is required.
