Cost-effective artificial graphite

Artificial graphite, as the name suggests, is graphite made by artificial methods. There are many ways to make artificial graphite common is to burn petroleum coke with the main raw material is a powdered high-quality calcined petroleum coke, in which asphalt is added as a binder, and a small amount of other excipients is added. After the various raw materials are well combined, they are pressed into shape, and then processed in a non-oxidizing atmosphere of 2500 ~ 3000 °C to make it graphitized.

Artificial graphite electrodes

Mainly petroleum coke, needle coke as raw materials, coal asphalt as a binder, through calcination, ingredients, kneading, pressing, roasting, graphitization, machining and made, is in the form of arc in the electric arc furnace to release electric energy to heat and melt the conductor, according to its quality indicators, can be divided into ordinary power, high power and ultra-high power. Graphite electrodes include:

(1)Ordinary power graphite electrode. It is allowed to use graphite electrodes with an current density of less than 17A/cm2, and is mainly used for ordinary power electric furnaces for steelmaking, silicon, yellow phosphorus smelting, etc.

(2) Anti-oxidation coated graphite electrode. The surface is coated with a layer of anti-oxidation protective layer of graphite electrodes, forming a protective layer that can both conduct electricity and resist high temperature oxidation, reducing electrode

(3) High power graphite electrode. Graphite electrodes with a current density of 18~25A/cm2 are allowed, mainly used for high-power electric arc furnaces for steelmaking.

(4) Ultra-high power graphite electrode. Graphite electrodes with an current density greater than 25A/cm2 are allowed. Mainly used in ultra-high power steelmaking electric arc furnace.

Artificial graphite anodes

Mainly based on petroleum coke as raw material, coal asphalt as a binder, through calcination, ingredients, kneading, pressing, roasting, impregnation, graphitization, machining and making. It is generally used for conductive anodes of electrolytic equipment in the electrochemical industry. Include:

(1) Various chemical anode plates.

(2) Various anode rods.

current density greater than 25A/cm2 are allowed. Mainly used in ultra-high power steelmaking electric arc furnace.

Special artificial graphite

Mainly based on high-quality petroleum coke as raw materials, coal asphalt or synthetic resin as binders, through raw material preparation, ingredients, mixing, tableting, crushing, remixing, molding, multiple roasting, multiple infestation, purification and graphitization, machining and made. It is generally used in the aerospace, electronics, and nuclear industries.

It includes spectral pure graphite, high purity, high strength, high density and pyrolytic graphite.

Artificial graphite heat exchanger

Artificial graphite is processed into the desired shape, and then impregnable graphite products for heat exchange made of resin impregnation and curing, which is a heat exchange equipment processed with artificial impermeable graphite as the matrix, mainly used in the chemical industry. Include:

(1) Block hole heat exchanger;

(2) Radial heat exchanger;

(3) Falling film heat exchanger;

(4) Tubular heat exchanger.

Most of the carbon anode materials of artificial graphite are still in the research and development stage, although non-carbon anode materials have greater advantages than carbon materials in some aspects, such as higher specific capacity, better cycle performance, better magnification performance, etc., but at the same time there are many problems to be solved, such as volume expansion during charge and discharge, voltage lag, poor safety, etc.

Franli factory on artificial graphite for a detailed analysis, compared with the same industry to manufacture artificial graphite material prices, in 2020 before China’s manufacturing of artificial graphite cost decline, but in 2021, because of the impact of the continuous epidemic, so that the cost of materials and market prices rose rapidly, we has a set of research and development of artificial graphite assembly line, artificial graphite varieties are diverse, different standards of carbon content, in this overall market price increase supply period, Franli LLC will give you the highest quality, as well as the best value for money artificial graphite.
