In the development history of China's carbon materials industry, the management scope was divided according to the application direction and distribution system of carbon materials, and there were the following types of carbon materials manufacturers:
(1) a carbon material enterprise that produces graphite electrodes, graphite anodes, carbon blocks for metallurgical furnaces and self-baked anodes for steel, metallurgy and chemical industries.
Its leading products are graphite electrode, graphite anode, carbon block and electrode paste for electric arc furnace.
High strength, high purity and high density graphite can be produced by the equipment and technology for producing graphite electrodes.
These carbon materials have wide applications in nuclear, aerospace and other industries.
In China, such enterprises are usually referred to as "carbon plants".
Graphite chemical equipment can be produced by impregnating graphite blank in carbon plant with resin after processing.
The past production of graphite electrode, carbon block, electrode paste and other products
The plant is managed by the ministry of metallurgy and the department of metallurgy of each province, and the factory producing graphite anode and graphite chemical equipment is managed by the ministry of chemical industry and the department of chemical industry of each province.
(2) enterprises producing carbon materials for electrolytic aluminum.
Electrolytic aluminum industry is the largest user of carbon materials, products have electrolytic cell lining carbon block, conductive pre-baked anode or anode paste.
Electrolytic aluminum plants generally have carbon plants (or workshops), specializing in the production of pre-baked anode or anode paste, some electrolytic aluminum plants also have carbon block factories, the production of aluminum electrolytic cell bottom and side carbon block.
In the past, its competent department was the general administration of nonferrous metallurgy industry (now aluminum corporation of China), whose annual output of carbon products was separately counted.
(3) enterprises producing carbon materials for the electrical and mechanical industries.
Its main products are electric brushes, electric locomotives with conductive slider, arc carbon rod, mechanical bearings and seals, leading products are brushes and carbon wear parts.
In China, such enterprises are commonly referred to as "electric carbon plants".
In the past, its competent departments for the ministry of machinery and the corresponding provinces and cities, their output statistics.
(4) enterprises that mine and process natural graphite, diamond and other materials.
Its products include carbon fiber, pyrolytic carbon, glass carbon, graphite interlaminar compound (expanded graphite), etc. The raw materials, production equipment and production process used are quite different from conventional carbon and graphite products.
Some carbon enterprises have a branch plant or workshop to produce such products, and some have a separate plant.
With the abolition of the ministry of industry of the central government and the corresponding agencies of various provinces and cities, carbon materials production enterprises are market-oriented, independent management, and voluntary organization of trade associations for coordination.
These trade associations are still organized according to the original affiliation, so there is no national organization in charge of or coordinate the production of carbon materials, and there is no organization to compile the annual production data of the whole industry.
The end of the 20th century, hundreds of carbon material production enterprises in China, most business with close ties to join industry associations, such as metallurgy industry association of the Chinese carbon industry association and China coking industry association, China electrical equipment industry association electrical carbon branch, China non-metallic mineral industry association of professional committee of the graphite and carbon black branch of China rubber industry association, etc.
As an experienced supplier, we now offer everything from RP, HP to UHP graphite electrode and trapezodial, oval, cylinder electrode paste in the world.
Our products meet and exceed the challenges of thousands of applications, and continue to be innovated.
