Product Description:


Carbon Additive/Calcined Anthracite Coal may substitute massively refinery coke or graphite. Meanwhile its cost is much less than the refinery coke and graphite. Carbon Additive is mainly used in electric steel ovens, water filtering, rust removal in shipbuilding and production of carbon material. 



Carbon Additive also called Calcined anthracite Coal, Gas Calcined Anthracite Coal, Carbon Raiser, Recarburizer, injection coke, charging coke and etc. It is playing more and more important role in the industry.

The main raw material of our Carbon Additive is Ningxia unique high quality Taixi anthracite, with characteristic of low ash and low sulfur. it is playing more and more impoetant role in the steel industry. Carbon additive has two main usage, fuel and additive. When being used as the carbon additive of steel-smelting, and casting, the fixed carbon may achieve above 95%.

Best quality Taixi anthracite as raw materials through high temperature calcined at 1200-1250 for 24 hours  by the DC electric calciner with results in eliminating the moisture and volatile matter from Anthracite efficiently, improving the density and the electric conductivity and strengthening the mechanical strength and anti-oxidation, It has good characteristics with low ash, low resistivity, low carbon and high density. It is the best material for high quality carbon products, it is used as carbon additive in steel industry or fuel.

Q:Which carbon content is larger, steel or pig iron?
The carbon content of pig iron is large. The carbon content of pig iron is usually 2.5%--4%, and the carbon content of steel is 0.05% - 2%
Q:Carbon injection molding machine heating several degrees
The nozzle temperature is 260~310 degrees, and the temperature control of the two types of injection molding machine nozzles is different. The mold temperature has great influence on the mechanical properties of the products. With the increase of mold temperature. The temperature and the temperature difference between the temperature decreases, the shear stress decreases, can melt in the mold cavity slow cooling, the molecular chain orientation to relaxation reduced, thereby reducing the internal stress of products, but the impact strength and elongation of the products decreased significantly, while there will be demolding. When demoulding, it is easy to deform, prolong the molding cycle and reduce the production efficiency, while the lower mold temperature will increase the internal stress of the product. Therefore, the die temperature must be controlled. Normally, the mold temperature of PC is 80~120 degrees centigrade. Ordinary products are controlled at 80~100 degrees, while for complex shapes, thin walls and high requirements, the product is controlled at 100~120 degrees centigrade and is not allowed to exceed its thermal deformation temperature. Mold temperature control is particularly important when forming PC thick wall products.
Q:How does carbon form?speed
How is coal formed?Coal is known as black gold, the food industry, it is one of the main energy use of the human world since eighteenth Century. Although its important position has been replaced by oil, but in the future for a long period of time, due to the exhaustion of petroleum, inevitable decline, but because of the huge reserves of coal, and the rapid development of science and technology, the new technology of coal gasification is becoming more mature and widely used, coal will become one of the production and life of human beings in an irreplaceable energy.Coal is millions of years of plant leaves and roots, stacked on the ground with a layer of very thick black humus, due to changes in the earth's crust constantly buried underground, long isolated from the air and under high temperature and pressure, after a series of complex physical and chemical changes and other factors, the formation of black however, this fossil, is the coal forming process.The thickness of coal seam in a coal mine and the crust drop speed and accumulation amount of plant remains. The crust decreased rapidly, the plant remains piled thick, the coal seam is thick, on the other hand, the crust decline slowly, the accumulation of plant remains thin, the mine coal seam is thin. The tectonic movement of the crust to the original level of coal seam folds and faults occur, some underground coal seam buried deeper, and squeezed to the surface, even above the ground, more likely to be found. There are some relatively thin coal seam, and the area is not large, so there is no value related to the formation of coal mining, so far not find the update statement.
Q:The similarities and differences of five existing forms of cementite in iron carbon alloy are analyzed
Three: cementite in iron graphite in the phase diagram of F (Fe) + Fe3C two-phase region precipitation of Fe3C is three times the cementite formation temperature in the eutectoid temperature (727 DEG C), morphology is fine flake or granular.Eutectic cementite: Fe3C body in eutectic (A (Fe) + Fe3C) formed at eutectic temperature (1148 DEG C). The morphology is lamellar eutectic morphology. The carbon content is about 4.3%.Eutectoid cementite: Fe3C in eutectoid (F (Fe) +Fe3C) formed at eutectoid temperature (727 DEG C), characterized by flaky eutectoid morphology. The carbon content is about 0.77%.
Q:What is the basic principle of carbon fourteen detection?
Carbon fourteenCarbon fourteen, a radioactive isotope of carbon, was first discovered in 1940. It is produced by hitting twelve carbon atoms in the air through cosmic rays. Its half-life is about 5730 years, the decay is beta decay, and the carbon 14 atoms are converted to nitrogen atoms. Since its half-life is 5730 years, and carbon is one of the elements of organic matter, we can infer its age by the 14 component of the residual carbon in the dying organism. When living in the biological, because need to breathe, the carbon content of 14 in its body is about the same, the organisms die will stop breathing, at this time the carbon 14 in the body began to decrease. Since the proportion of carbon isotopes in nature is always stable, one can estimate the approximate age of an object by measuring its carbon 14 content. This method is called carbon dating. Other commonly used methods include potassium argon measurements, potassium argon measurements, thermoluminescence measurements, and others;
Q:What is sintered carbon?
The process of choosing appropriate process and operating systems in accordance with the internal laws of the sintering process, the use of modern scientific and technological achievements, strengthening sintering production process, to obtain advanced technical and economic indicators, to ensure the realization of high yield, high quality and low consumption. The production process has the raw materials, against the ash, mixing, crushing and screening, crushing and screening solvent fuel proportioning, mixing, ignition, exhaust ventilation cooling, sintering, crushing and screening, dust and other aspects.
Q:How do you get DNF advanced furnace rock carbon?
To strengthen the ordinary senior rock colorless, furnace carbon is used advanced, the mall did not buy, according to that wish gift box can be opened in some special activities in the last device can be bought in, no other time
Q:Which brand is good for carbon fiber board?
You are not for the prestressing bar, if you find the building reinforcement for Tianjin Beijing card, if you do the structure reinforcement for Jiangsu and Wuxi via the new material industry, these are relatively well-known.
Q:What's the difference between carbon steel pipes and stainless steel pipes and seamless steel tubes?
Carbon steel pipe and stainless steel pipe with the material classification, and the seamless steel tube is shaped by divided categories.
Q:Why does carbon fiber produce far infrared rays when it is heated?
When it is energized, its motion intensifies, the frequency becomes V2, and the frequency becomes larger, the vibration system is unstable and the frequency is back to its original frequency. So you have to release energy in the form of electromagnetic waves. I am not too clear about the specific release process. I know that the molecules do slow motion and generate additional electromagnetic waves. The frequency of the extra electromagnetic wave emitted is v2-v1, and its frequency falls in the far infrared region.
