The reduction furnace is mainly used for high-temperature precision, microcrystalline ceramic glaze preparation, mold, powder sintering, and plastic powder experiments. Nanomaterials and metal parts are annealed under atmospheric protection. It is widely used in laboratories and industrial and mining enterprises of institutions of higher learning and scientific research institutes for sintering, melting, analysis and production of ceramics, metallurgy, electronics, glass, chemical industry, machinery, refractory materials, new material development, special materials, building materials, metals, non-metals and other chemical and physical materials.

the structural principle of reduction furnace:

The reduction furnace uses silicon molybdenum rods as heating elements, adopts a double-layer furnace shell structure, a program-controlled temperature control system, phase shift trigger, and thyristor control. The furnace body is made of alumina polycrystalline fiber material, and the double-layer furnace shell is equipped with an air cooling system, which can quickly cool the temperature control system. The furnace shell is sealed as a whole, the cover plate is silicone, the furnace door is sealed with silicone gasket, and is equipped with a water cooling system. The gas passes through the flow meter and enters and exits the rear chamber. The washing furnace with combustion nozzles has many air inlets and outlets through which hydrogen, argon, nitrogen, oxygen, carbon monoxide and other gases can pass. The reduction furnace has the advantages of temperature field equilibrium, low surface temperature, fast heating speed and energy saving.

Main functions and features of reduction furnace:

1. Over-temperature alarm, power failure and leakage protection, safe and reliable operation.

2. The furnace door adopts circulating water cooling system, which can effectively ensure the overall sealing;

3. Equipped with imported pressure sensor, overpressure automatic pressure relief protection, safe and reliable operation;

4. Can pre-vacuum, can be filled with ammonia decomposition gas, argon, nitrogen and other gases. The furnace is equipped with expansion overpressure explosion-proof system;

5. Multiple heating curves can be preset and assigned to different sintering materials, which can be directly called when needed, without interfering with each other, without repeatedly modifying temperature parameters;

6. The reserved 485 conversion interface can be interconnected with the computer through our software, which can realize remote control, real-time tracking, historical records, report output and other functions. Single or multiple electric furnaces;

7. The heating elements are evenly distributed in the round or square alumina furnace, with reasonable distribution, good temperature field uniformity, and vacuum pumping. The vacuum degree can reach below 0.05mPa, and various protective atmospheres can be passed;

8. The reduction furnace adopts imported alumina polycrystalline fiber material, which has good heat preservation performance, durability, high tensile strength, no impurities, high purity, and the energy-saving effect is obviously better than domestic fiber materials.

In summary, the atmosphere reduction furnace is characterized by the introduction of a certain composition of artificial preparation atmosphere into the furnace at a certain set temperature, in order to achieve certain heat treatment purposes, such as gas carburizing, carbon-nitrogen co-penetration, bright quenching, annealing, positive fire and so on. In order to maintain a certain carbon potential in the furnace, in addition to controlling the stability of the atmosphere composition, it is also necessary to control the carbon potential in the furnace.
