1. Metallurgical industry
Previously used for smelting iron ore, charcoal on charcoal and coke smelting of iron, even if the same chemical composition, structure and mechanical properties are still the same. Charcoal smelting of pig iron generally has fine structure, casting tight, no cracks in the characteristics of the production of pig iron using charcoal containing impurities less suitable for producing high quality steel. As the charcoal is reductive, so can be used to restore the metallurgical industry ore smelting metal.
In the non-ferrous metal production, charcoal is often used as surface flux, when the non-ferrous metal melting, the surface flux in the molten metal surface protective layer, so that separation of metals and gases, can reduce the loss of molten metal splash, but also reduce the melting material in gas saturation.
A large number of charcoal is also used to produce crystalline silicon, crystalline silicon used in charcoal production should not contain too many students head and charcoal ash.
2. Carburizing agent manufacturing
All requirements of high surface hardness and wear resistance, good toughness and the center of all steel products should be cementite. Carburizing of steel products used to carry out the role of carbon compounds known as carburizing agent. Carburizing pure charcoal less effective. Therefore, charcoal used as a raw material, then add a certain amount of contact with agents, made of carburizing agent.
3. Disulfide production
Charcoal is the manufacture of carbon disulfide in the best raw materials used to produce carbon disulfide in the charcoal, should be hard, great volume, ash and moisture content in small, fixed carbon content.
Produce about 1 ton of carbon disulfide, 0.5 tons of charcoal.
4. Charcoal brick repression
Crushed charcoal transport is very convenient, but use is restricted, with the suppression of the value of charcoal bricks in the way that it can become a high-quality small pieces of charcoal fuel. Charcoal bricks with water absorption and water absorption of small, heavy, and the advantages of high calorific value, but also in the process of using a high mechanical strength. Burning off burning charcoal bricks in a smoke-free, does not produce carbon dust. Charcoal brick can be used for metallurgy, such as mobile gasifier.
Mechanism charcoal, we normally referred to as charcoal, charcoal regeneration, artificial carbon, green charcoal, charcoal and other smoke-free. First developed by the Japanese machine-made charcoal, the product called "wood strength loss servant", after the journey to Taiwan before coming to the mainland!
What is the mechanism of charcoal like? The outline is usually about 5 cm in diameter square, hexagonal and round three, the length can be any interception, usually 8-50 cm long, the middle of a small hole, side ventilation with! Mechanism of charcoal is usually used in the original wood and bamboo cuttings, by special rods for high pressure extrusion molding machine, of course, is the use of raw materials before using the dryer drying to moisture content below 10% only! Many people think that rice husk, peanut shell, corn cob, corn stalks, sorghum stalks, etc. can also be fired into carbon, is yes, with these materials can be compressed into bars, can not be carbonized into charcoal! Why?
Because these materials contained in the fiber structure and different elements are different, making the remaining ash after use a lot of value is very low burning, fire is not big enough!
Mechanism charcoal because after high pressure high temperature, so much the density is generally 2 to 3 times the timber is about 3 times the natural charcoal! Is peat, coke 4 to 5 times! Equivalent to the proportion of anthracite (Anthracite 1350 ~ 1800 kg / cubic meter)! Although rich in coal resources, but high sulfur and high ash coal more, while low-sulfur, low ash coal less. Example, the average Chinese steam coal ash is 28% -30%, the sulfur content of coal is also high, the national average of 1-1.2%, in the southern region in general as much as 4%. The coal that is, if not addressed directly to fuel use,
Will cause serious pollution of sulfur dioxide and soot. The mechanism of charcoal also the solution of this problem, it contains only less than 5% ash, the heat can reach 7000-8000 kcal / KG! Mechanism of carbonized charcoal kiln in the process of carbonization, has the most harmful substances in combustion, decomposition of the! So has the proportion of machine-made charcoal (high density), high heat value, low cost, easy to use, clean the advantages of easy storage and transport, is living, heating and industrial production, energy use, and can replace coal, combustion solid (ash) emissions than coal
Reduction of waste emissions, but also easier to handle, little environmental pollution; gas emission targets much better than the national gas emission standards.
Mechanism charcoal vast market. Hotels, factories, agriculture, animal husbandry, metallurgy, environmental
