First, carbon and graphite products
(A) of the type of graphite electrodes
Mainly petroleum coke and needle coke as raw materials, coal for asphalt binder, calcination, the ingredients, mixed pinch, pressure-type, roasting, graphite, machine processing and made in the electric arc furnace in the form of electric arc furnace charge for the release of energy For the melting heat conductor, according to the quality of their high or low, can be divided into ordinary power, high-power and ultra-high power. Graphite electrodes are:
(1) general power graphite electrodes. To allow the use of current density lower than 17A / cm 2 of graphite electrodes, used steel, silicon smelting, refining of yellow phosphorus, such as general electric power.
(2) anti-oxidation coating of graphite electrodes. Anti-oxidation coating on the surface layer of protective coating of graphite electrodes, which form a high-temperature conductivity oxidation and the protective layer to reduce consumption of steel when the electrode.
(3) high-power graphite electrodes. To allow the use of current density to 18 ~ 25A / cm 2 of graphite electrodes, used high-power electric arc furnace steel-making.
(4) UHP graphite electrodes. To allow the use of current density is greater than 25A / cm 2 of the graphite electrode. For ultra-high-power electric arc furnace steel-making.
(B) graphite-anode-type
Mainly petroleum coke as raw materials, coal for asphalt binder, calcination, the ingredients, mixed pinch, pressure-type, baking, impregnation graphite, machined and made of. Electrochemical industry in general for the conductive anode electrolysis equipment. Include:
(1) anode plate with a variety of chemicals.
(2) a variety of anode rod.
(C) special type of graphite
Mainly in high-quality raw materials for petroleum coke, coal or asphalt binder for the synthetic resin, the raw materials preparation, ingredients, mixing pinch, the pressure tablets, crushed, mixed pinch, molding, baking many, many times invaded stains, and the purification of graphite, The processing machine made. General for the aerospace, electronics, nuclear industry.
It includes the spectrum of pure graphite, high purity, high-strength, high density and the pyrolytic graphite, and so on.
(D) of the graphite heat exchanger
Artificial graphite would be converted into the required shape and then impregnated resin and curing and made of heat exchange for the non-permeability graphite products, it is not man-made permeability graphite matrix for the processing of heat transfer equipment from the main For the chemical industry. Include:
(1) of the block-hole heat exchanger;
(2) radial heat exchanger;
(3) falling-film heat exchanger;
(4) Tubular heat exchangers.
(E) of the type of carbon electrode
To carbonaceous materials such as coal and metallurgical coke (or petroleum coke) as raw materials for the asphalt binder of coal, not after graphite and suppressed by the molding and sintering electrode conductivity. It is not suitable for high-alloy steel smelting furnace. Include:
(L) multi-electrode Gray (with anthracite, metallurgical coke and coke Asphalt production of the electrodes);
(2) renewable electrode (with artificial graphite, natural graphite electrode production);
(3) carbon rod resistance (that is, the carbon lattice brick);
(4) carbon anode (using petroleum coke prebaked anode production);
(5) roasting electrode blank.
(F) category carbon block
To anthracite, the main raw material for metallurgical coke, coal tar pitch as a binder, the preparation of raw materials, ingredients, mixing stick, molding, roasting, processing and machine made. One blast furnace as a high-temperature corrosion-resistant carbon block material for blast furnace lining masonry; at the bottom of the carbon block, carbon block side, the electric furnace is used in aluminum reduction cell block and ferro-alloys, such as electric stove. Include:
(1) carbon block blast furnace;
(2) aluminum tank carbon block (the bottom side of the carbon block and the Ministry of carbon block);
(3) electric furnace carbon block.
(G) of carbon paste category
Petroleum coke, coal, metallurgical coke as the main raw materials, coal and made of asphalt binder. Some used for a variety of self-baking furnace in a row as the use of electrode electrodes conductive paste; in a row for some self-baking-groove aluminum anode used as a conductive paste anode; blast furnace for some of the masonry and fill the thick mud fire-resistant Seam paste and paste slit. Blast furnace with self-baking carbon block Although the use of different, but the paste-type products and production processes similar to the suspense in the paste-type products within. Include:
(1) anode paste;
(2) electrode paste (including standard, non-standard electrode paste);
(3) at the end of paste (including more gray, less Huidi paste);
(4) confined paste (including multi-gray, gray less confined paste);
(5) other paste (including crack rough paste, paste slit, the self-baking carbon brick, etc.).
(H) non-standard carbon and graphite products category
This refers to the use of carbon and graphite products through further processing and selling a variety of different types of carbon and graphite products. Including shovel-type anode, the fluoride system, as well as a variety of specifications of the anode crucible, plate, bar, block-shaped, and other goods.
(I) non-permeability-type graphite
This refers to a variety of resins and organic matter by the impregnation, processing and made of a variety of special graphite products, including the heat exchanger block matrix.
(X) class of electrical carbon products
This refers to the carbon rod, brush and other products.
Second, carbon fiber
It includes a variety of carbon fiber and graphite fiber, pre-wire oxygen, carbon cloth, with carbon, carbon rope, carpet and carbon composites. One carbon fiber for the carbon content higher than 93% of the fiber. Polypropylene fiber with eyes, silk and viscose fiber asphalt made by the carbonation. Heat from low to high temperature, can be made of heat-resistant fiber, fiber and graphite fiber carbonation.
