工業冶煉木炭 木炭出口 高溫機制木炭

1.冶金工業
　 　以前木炭就用來冶煉鐵礦石，木炭與焦炭熔煉的生鐵，即使化學組成相同，其結構與機械性質仍不相同。木炭冶煉的生鐵一般具有細粒結構，鑄件緊密，沒有裂紋的特點，用木炭生產的生鐵含雜質少，適於生產優質鋼。由於木炭具有還原性，所以在冶金工業可以用來還原礦石冶煉金屬。
　　在有色金屬生產中，木炭常用作表面助熔劑，當有色金屬熔融時，表面助熔劑在熔融金屬表面形成保護層，使金屬與氣體介質分開，既可減少熔融金屬的飛濺損失，又可降低熔融物中氣體的飽和度。
　　大量木炭還用於結晶硅生產，生產結晶硅用的木炭不應含有生炭頭和過多的灰分。
2.滲碳劑的製造
　　凡是要求表面具有較高的硬度和耐磨性，而中心具有良好韌性的所有鋼製品都要進行滲碳。用來對鋼製品進行滲碳作用的含碳混合物稱為滲碳劑。單純木炭的滲碳效果較差。因此常用木炭作為原料，再加入一定數量的接觸劑，製成滲碳劑。
3.二硫化碳生產
　　木炭是製造二硫化碳的最好原料，用來製造二硫化碳的木炭，應當是堅硬、容積重大、灰分和水分含量小，固定碳含量高。
　　生產1噸二硫化碳約需0.5噸的木炭。
4.木炭磚的壓制
　　碎木炭運輸很不方便，而且用途也受到限制，用壓制木炭磚的方法能使價值很小的碎木炭變成優質燃料。木炭磚具有吸濕性和吸水性小、比重大和熱值高的優點，而且在使用過程有很高的機械強度。鍛燒過的木炭磚在燃燒時無煙，不產生炭塵。木炭磚可用於冶金、移動式氣化爐等。

機制木炭，大家平常簡稱機制炭、再生木炭、人造炭、環保木炭、無煙炭等。機制木炭最先由日本研製，產品稱"木力虧僕"，後傳到台灣，然後才轉到內地來的！

機制木炭是什麼樣的呢？通常外型為直徑5厘米左右的四角形、六角形和圓形三種，長度可以任意截取，一般為8到50厘米長，中間有一小孔，方面通氣用！機制木炭所用原來通常為木屑和竹屑，經專門的制棒機高溫高壓擠壓成型，當然原材料在使用前是要用烘乾機烘到只含水分10%以下！很多人以為稻殼、花生殼、玉米芯、玉米稈、高粱稈等也可以燒製成炭，是沒錯，用這些材料可以壓製成棒，可不能炭化成木炭！為什麼呢？因為這些材料所含纖維構造不同和元素不一樣，使得在使用後所剩的灰粉很多，燃燒值也很低，火力不夠大！

機制木炭因為經過高壓高溫，所以密度很大，是一般木材的2到3倍，也是自然木炭的3倍左右！更是泥煤、焦炭的4到5倍！相當於無煙煤的比重（無煙煤1350～1800千克/立方米）！雖然我國煤炭資源豐富，但高硫份、高灰份的煤炭較多，而低硫份、低灰份的煤炭較少。比如我國動力煤平均灰份為28％-30％，煤炭中的含硫量也很高，全國平均為1-1.2％，南部地區普遍高達4％以上。這些煤炭如果不加處理即直接燃用，就會產生嚴重的二氧化硫和煙塵污染。而機制木炭更本解決了這個問題，它所含的灰份僅少於5%，發熱量也能達到7000-8000大卡/KG！機制木炭在炭化窯裡炭化的過程中，已經把大部分有害物質燃燒，分解了！所以機制木炭具有比重大（密度高）、熱值高、成本低、使用方便、清潔衛生等優點，便於貯存和運輸，是居民生活、取暖和工業生產用能，可替代煤炭等，燃燒後的固體（灰粉）排放量低於煤炭，減少了廢渣排放，也比較方便處理，基本沒有環境污染問題；氣體排放指標大大優於國家氣體排放標準。

機制木炭的市場廣闊。飯店、工廠、農業、畜牧業、冶金、環保、實驗等！

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 protection and experiment!
