Who knows the graphite carbonization furnace, the reason why the graphitization furnace produces car

Graphitization furnace is mainly used for high-temperature treatment such as graphite powder purification. It can be used at temperatures up to 2800 °C. With the first temperature measurement and temperature control system, the temperature in the furnace can be monitored in real time and automatically adjusted.

Rated power: 50-1000kw

Input voltage: three-phase 380V

Operating temperature: 3000

Main uses: high-temperature sintering of cemented carbide materials; High temperature treatment of battery anode materials; Graphite powder high temperature treatment; sintering of high thermal conductivity films;

carbon fiber carbonization and graphitization treatment; high-temperature sintering of contact materials, precision ceramics, and high-temperature components; high-temperature sintering of powder metallurgy materials, tungsten carbide and other products; The firing of the product is completed under the protective atmosphere of argon.

Main features: the use temperature is up to 2800 degrees, the temperature uniformity is good, and the equipment operation failure rate is low. With infrared temperature measurement and temperature control system, it can display and PID automatically control the temperature in the furnace in real time (as shown below), and the quality of the products produced is stable.

Three-phase electric power supply mode is adopted, three-phase power balance, and stable performance. Unlike carbon tube furnaces, which use single-phase power supply, the phase voltage is unbalanced, which has a large impact on the power grid and affects the operation of other equipment. The use temperature is high, the maximum temperature can reach 3000, and it can work at 2600-2800.

Carbon felt is used as the insulation material, no carbon black is used, and it is convenient to replace the carbon tube, and it is clean and hygienic at the same time. The heating time is short, up to 200 hours. The furnace body has good sealing and low shielding gas loss.

All flanges and lids are sealed with sealing strips. The inner liner and flange of the furnace are made of stainless steel, which does not rust and has a long service life. It is equipped with a vacuum pump for the replacement of gas in the furnace, which has a short air exchange time and a small amount of gas.

Graphitization furnace is mainly used for high-temperature treatment such as graphite powder purification. High production efficiency, energy saving and power saving.

Carbon monoxide is a diatomic molecule, which is odorless, colorless, flammable and explosive, and insoluble in water. At the same time, carbon monoxide is a harmful gas to the human body, when it is inhaled into the human body, it will react with the hemoglobin in the blood to produce carboxyhemoglobin, because of its strong affinity with hemoglobin, the blood oxygen carrying rate will be reduced, resulting in a lack of oxygen in human tissues.

The causes of carbon monoxide in high-temperature graphitization furnaces are complex:

1. Carbon dioxide is generated in high-temperature graphitization due to the presence of carbon materials (mainly carbon insulation materials and graphite), oxygen and water molecules, and carbon dioxide reacts with carbon at high temperature to obtain carbon monoxide.

2. Carbon monoxide can also be produced by reacting with water vapor.

3. Carbon and carbon dioxide react to obtain carbon monoxide.

4. Carbon monoxide can also be obtained by carbon reduction iron oxide (trace elements in furnace shells or insulation materials) or copper oxide (intermediate frequency induction copper coil).

Graphite furnace is a non-flame atomizer, which is used in atomic absorption spectrometry, and is widely used in electrothermal atomizers. By Bili L'VOV was the first to propose that he overcame the shortcomings of the flame method. The essence of the graphite atomizer is the graphite resistance heater, which uses a large current to heat a graphite tube with high resistance value, generating a high temperature of up to 3000, so that it can be fused with a small amount of test liquid solids to obtain free atoms.

carbonizer；The carbonizing oven is horizontal, but there are two types: (1) the long tow adopts a furnace structure similar to that of the horizontal pre-oxidizing furnace, but due to the short residence time, several slit heating plate-shaped long furnaces with different temperatures are mostly used, and the tow is not in contact with the heating surface; (2) For non-woven or felt-like pre-oxidized filament, the above-mentioned carbonization furnace can be used, but if the carbonization temperature is not high, it can also be carried out in the conveyor belt furnace.

Each carbonization furnace is equipped with inert gas inlet and outlet.

The fiber trouser punching device for carbonizing the pre-oxidized filament (or phenolic precursor) is mainly a continuous furnace, and the batch furnace is purely a pre-oxidation furnace, which is destroyed by increasing the temperature.
