一、石墨增碳剂是指经过石墨化的增碳剂，在高温条件下，碳原子的排列呈石墨的微观形态，所以称之为石墨化。石墨增碳剂广泛应用于钢铁冶炼，可增加废钢用量，减少生铁用量或不用生铁，有效避免生铁的遗传性对铸件的影响；增碳效果稳定，吸收效果好，提温效果明显，不返渣；化学成分纯净：高碳、低硫、微氮，有害杂质少。

    二、石油焦增碳剂采用石油焦煅烧提纯等加工而成，外观呈圆粒或棱形，带有金属光泽，呈多孔性，是碳体物。石油焦特点在于高碳低硫，低灰，是冶金化工，机械，电力等行业理想的加碳材料和反应中间体，石油焦增碳剂是目前广泛应用的增碳剂。

    三、煤质增碳剂采用优质无烟煤做原料，是在1300℃高温干馏降低挥发份，用以提高固定碳含量和密度、强度，抗氧化性能而成的产品。其具有固定碳含量较高，抗氧化性强，有害元素含量低等特点。在冶炼过程中做还原剂用。增碳剂是为了补足钢液中所需的碳含量而增加的含碳物质。电弧炉炼钢过程中，可以在装料时配加焦炭或无烟煤作为增碳剂。由于其灰分和挥发分含量较高，感应电炉熔炼铸铁很少用作增碳剂。

    四、低硫增碳剂选用人造石墨为原料，在高温条件下，碳原子的排列呈石墨的微观形态。低的硫、氮、氢元素是防止铸件产生氮气孔的关键，这样就要求增碳剂的含硫量越低越好，其中效果最好的就是低硫增碳剂，由于其固定碳含量高、性能稳定、易吸收、增碳效果好等特点，所以也是至今为止用途较广泛的一种增碳剂。用于冶金炼钢增碳和球铁铸造增碳，用作耐磨润滑材料，铸造翻砂压膜及高温冶炼材料，原子能工业和国防工业，能防止锅炉结垢，作铅笔芯、颜料、抛光剂、电极等行业。

A, graphite recarburizer refers to after graphitization of carburant, under the condition of high temperature, carbon atoms arranged in the microstructure of graphite, so called the graphitization.Graphite carburant are widely used in steel smelting, can increase the dosage of scrap steel, reduce the dosage of pig iron or no iron, effectively avoid genetic influence on casting pig iron;Carburization effect is stable, good absorption effect, temperature effect is obvious, not return slag;Chemical composition of pure: high carbon, low sulfur, nitrogen, less harmful impurities.
Second, oil purification JiaoZeng carbon agent with petroleum coke calcining and appearance assumes the circular or prismatic, with metallic luster, is porous, is carbon body.Petroleum coke is characterized of high carbon low sulfur, low ash, is metallurgy chemical industry, machinery, electric power and other industries ideal carbon materials and intermediates, petroleum JiaoZeng carbon agent is currently widely used recarburizer.
Third, coal quality recarburizer do raw material is made of high quality anthracite, is at 1300 ℃ high temperature carbonization to reduce volatilization, to improve the fixed carbon content and density, strength, oxidation resistance of products.It has a fixed carbon content is higher, the oxidation resistance is strong, low content of harmful elements.In the process of smelting for reducing agent.Recarburizer to complement the carbon content in liquid steel and increase carbon material.In the process of the electric arc furnace steelmaking, when charging with addition of coke or anthracite as recarburizer.Due to its high ash content and volatile matter content, induction furnace melting cast iron is used as recarburizer rarely.
Four, low sulphur recarburizer artificial graphite as raw materials, under the condition of high temperature, the microstructure of carbon atoms arranged in a graphite.Low sulfur, nitrogen, hydrogen is the key to prevent castings from nitrogen air hole, so it requires recarburizer sulfur content is lower, the better, the effect is best is low sulfur carburant, due to its high fixed carbon content, stable performance, easy to absorb, increase carbon effect is good wait for a characteristic, so also is so far the versatile wide a recarburizer.Used for metallurgical steelmaking carbon and carbon ductile iron casting, used as lubricating materials, wear-resisting casting moulding pressure membrane and high-temperature smelting, atomic energy industry and defense industry, can prevent boiler scale, as a pencil lead, pigment, polishes, electrodes, etc.

增碳剂特点

      1、高固定碳，吸收率高，低硫低氮，并在吸收速度上快于同类石墨化增碳剂，且不吸附炉壁，完全吸收无残留，价格低于同类硫低于0.05以下的石墨化增碳剂，性价比最高。

      2、吸收率高,根据使用方法吸收率最高能达到90%以上。

      3、吸收速度快，比同类石墨化增碳剂吸收速度快，不吸附炉壁，且无残留，炉中增碳吸收速度优势更加明显。

      4、硫份低，0.05%以下，最低0.02%。氮份低，100ppm以下。

      5、超高的性价比，综述上述在同类石墨化增碳剂中（硫≤0.05）价格最有优势。

1, high fixed carbon, high absorption rate, low sulfur, low nitrogen and the absorption rate faster than the same kind of graphitization carburant, adsorption furnace wall, and not fully absorbed no residue, price is lower than the similar sulfur is lower than 0.05 following the graphitization of carburant, highest performance-to-price ratio.
2, high absorption rate, according to the method of use highest absorption rate can reach more than 90%.
3, absorption speed, than the same kind of graphitization recarburizer fast absorption, adsorption of furnace wall, and no residual, furnace carbon absorption speed advantage is more obvious.
4, low sulfur, below 0.05%, the lowest 0.02%.N a low, 100 parts per million.
5, high cost performance, review the above in the same kind of graphitization recarburizer (0.05) or less sulfur price is most advantage.

    用于铸造、铸铁、铸钢和铸件会有对碳的一个要求，那么增碳剂顾名思义就是来增加铁液中的碳含量，又比如说，在熔炼中常用炉料为生铁、废钢、回炉料，生铁的碳含量高，但是采购价格相对废钢来说是要高出一节的，所以增加废钢投放量，降低生铁投放量，加增碳剂，能起到一定的降低铸件成本的作用。

Used for casting, cast iron, cast steel and casting there will be a requirement for carbon, carburant just as its name implies is to increase the carbon content in liquid iron, and, for example, commonly used in smelting furnace charge for pig iron, scrap steel, back to the furnace charge, iron carbon content is high, but relatively scrap purchase price is higher section, so adding scrap supply, reduce the quantity of pig iron, increase carbon agent, can reduce the casting cost play a role.
