Product Description

1.Structural composition
Furnace body: It is usually made of steel plates as the outer shell, with refractory materials that are resistant to high temperatures and erosion, such as magnesia chrome bricks, corundum bricks, etc., built inside to withstand high temperatures and slag erosion, reducing heat loss. The furnace cover is equipped with electrode holes, feeding ports, observation holes, and exhaust ports.
Electrode system: including electrodes, electrode holders, and electrode lifting devices. Electrodes are generally made of graphite or self baked electrodes, which have good conductivity and high temperature resistance. The electrode holder is used to fix the electrode and conduct current to the electrode. The electrode lifting device can automatically adjust the position of the electrode according to the reaction situation inside the furnace and the height of the furnace material, to ensure stable arc and maintain uniform temperature inside the furnace.
Feeding system: composed of material bin, feeder, conveying device, etc. Its function is to accurately and continuously add chromium ore, coke, auxiliary materials, etc. into the furnace in a certain proportion. Modern feeding systems are usually equipped with automatic metering and control devices, which can accurately control the amount of raw materials added.
Smoke exhaust system: installed on the top or side of the furnace, used to collect and exhaust high-temperature flue gas generated during the smelting process. The smoke contains harmful substances such as dust and carbon monoxide, which need to be cooled, dedusted, purified, and treated before reaching emission standards.


Technical Parameter:
Electric furnace power: The power of the electric melting chromium oxide electric furnace is relatively high, generally between several thousand kilowatts and tens of thousands of kilowatts. High power can provide sufficient heat to ensure fast and efficient reactions inside the furnace and improve production efficiency.
Working temperature: The working temperature inside the furnace is usually around 2000-2500 ℃. High temperature is a key condition for achieving chromium oxide reduction and purification of chromium ore. However, excessive temperature will increase energy consumption and equipment loss, and the temperature needs to be controlled within an appropriate range.
Electrode current density: The electrode current density is generally controlled within the range of several amps to tens of amps per square centimeter. The appropriate current density is crucial for the normal operation of the electrode and the heating effect inside the furnace.


3.Application area 
The electric melting chromium oxide produced by the electric furnace has a wide range of application fields, mainly including the following aspects:
Manufacturing of grinding tools: Due to its high hardness and wear resistance, fused chromium oxide can be used to manufacture grinding tools such as grinding wheels, grinding wheels, drill bits, and grinders. It can also be used as a filler for ceramics and metals to improve their wear resistance and hardness.
Coating preparation: It can be used as a raw material for high-temperature coatings and applied in fields such as aviation, aerospace, and energy to improve the corrosion resistance, wear resistance, oxidation resistance, and corrosion resistance of metal parts. It can also be used for coating preparation in fields such as batteries, fireproof materials, ceramics, etc.
Thermal barrier coating: As a raw material for thermal barrier coatings, it is applied in the preparation of coatings for high-temperature equipment such as engines, turbines, and gas turbines to prevent the transfer of high-temperature heat to metal surfaces and protect mechanical equipment and components.
In the field of ceramics, it can be used together with other metal oxides for the preparation of ceramics, such as aluminum oxide for the preparation of electrical ceramics, which can improve the strength and hardness of ceramics, as well as their wear resistance and heat resistance.
Battery materials: can be used as raw materials for battery positive electrode materials, applied in the preparation of nickel cadmium batteries, lead-acid batteries, lithium-ion batteries and other batteries, meeting the requirements of battery positive electrode materials for conductivity, stability, corrosion resistance and durability.
