Calcined Anthracite Coal


• Calcined Anthracite Coal Feature:

All of our goods are made in the best quality with high carbon, low ash, low Sulphur, low moisture.



• Calcined Anthracite Coal Application:

Calcined anthracite coal/gas calcined anthracite coal/carbon raiser is mainly used in steelmaking in electrical stove, screening water, shipbuilding sandblast to remove rust. It can reduce the cost of steelmaking effectively by replacing the traditional petroleum coke of carburant. Also, it can improve the carbon content in steel melting and ductile iron foundry.

Q:What is the proportion of raw coal
Anthracite powder density of 0.84 ~ 0.89 g/cm3, lignite density of 0.6 ~ 0.8 g/cm3.
Q:What are the signs of coal and gas outburst?
Before coal and gas outburst, there is usually a sign, and there is no sign of the very fewSound sign: a seam splitting sound, the sound of muffled thunder, machine guns, guns and coal gas through the water ring cracks squeak. The sound from far to near, from small to large, short, continuous, interval is not consistent; vibration and impact the coal wall roof pressure, also. A stent fracture.Silent sign: the roof pressure, coal wall spalling by extrusion, the dregs, along the roof or floor muster; coal seam coal bedding disorder, dull, soft coal; gas flickering, coal wall cold, drilling with top drilling, sticking and spraying gas and so on.
Q:Activated carbon is what?
The chemical formula of activated carbon is C, activated carbon has a strong physical adsorption, adsorption of organic compounds can be achieved to remove the effect
Q:Effect of carbon on steel
The formation of solid solution organization, improve the strength of steel, such as ferrite, austenite structure, dissolved in carbon elements;2 carbide structure, can improve the hardness and wear resistance of steel. Such as cementite, that is, Fe3C, carbide structure.
Q:Activated carbon rain has been poured into the useful
Look at the density of activated carbon pore number, the adsorption performance of activated carbon is higher, more crisp, the relative density is low, will feel lighter in weight in the case of packaging, the volume is also bigger. The proposed purchase of small density, light touch, such as the weight of large volume of activated carbon products.
Q:Usually we use coal as fuel to get heat in the process of combustion
Coal can be obtained through the air temperature from coke, coal tar, coke oven gas fractionation, coke and coke oven gas for fuel, high calorific value, and little pollution; coal tar is a kind of important chemical raw materials contain a variety of resources, can extract the essence, making explosives and nylon etc.. Thus, the coal is comprehensively utilized, and the environmental pollution is reduced
Q:Why is coal spontaneous combustion?
Coal heap in contact with air oxidation occurs, and emit heat. Coal oxidation reaction occurs after the coal pile temperature increases. The coal temperature increases, and the speed of coal oxidation was accelerated. In this way, the temperature makes the coal pile increasing. When the temperature exceeds the coal self ignition when will the spontaneous combustion
Q:What is called carbon baking paint?
Fluorocarbon baking varnish with fluorine resin as the main film forming material; also known as fluorocarbon paint, fluorocarbon coating, fluorocarbon resin coating. In a variety of coating, fluorocarbon resin coatings due to the introduction of fluorine element electronegativity, fluorocarbon bond energy, has the good performance
Q:What is engineering coal
2 gasification. Gasification refers to the conversion of industrial or civil fuel as well as chemical synthesis of raw materials.3 cryogenic distillation. Low temperature tar and low temperature coke oven gas can be prepared by low temperature carbonization of coal or oil shale at the temperature of 550 DEG C.4 hydrogenation liquefaction. The coal, the catalyst and the heavy oil are mixed together, and the organic matter in the coal is destroyed at high temperature and high pressure, and the hydrogen is converted into low molecular liquid and gaseous products.
Q:Coal is used to do?
. Some low ash, low sulfur and high HGI anthracite is also used as raw material for blast furnace injection. Coal: coal soot level top coal, it is characterized by a higher ignition temperature (350 - 360 DEG C), high calorific value, weak bond or not. Coal is mainly used for power generation and power plant boiler fuel. The use of coal, and the other with the use of high volatile coal is also a good way. Lean coal: low volatile, low bond strength, can be used alone to coking. As with other suitable for coking coal blending, lean coal incorporation will make block increase the degree of coke products.
