90-95含量煤质增碳剂 低硫高碳煤质增碳剂

增碳剂简介：

    增碳剂的原料有很多种，生产工艺也各异；有木质碳类，煤质碳类，焦炭类，石墨类等，其中各种分类下又有很多小种类。质量高的增碳剂一般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。石墨化可以降低增碳剂中杂质的含量，提高增碳剂的碳含量，降低硫含量。适用于铸钢（炼钢）以及灰铁铸造增碳。具有高碳、低硫、低含水量且成本低及性价比高的特点。

    国内目前常用的增碳剂有3种：

    一是石墨粉，就是石墨电极加工的吸尘粉。

    二是煅后石油焦，国内的一些钢铁厂，就是用煅后石油焦，做增碳剂的。

    三是石墨化石油焦，也是用在炼钢上，做增碳剂用。

增碳剂指标：

增碳剂用途：

    适用熔炼工艺：

    感应电炉炉内增碳；冲天炉炉内增碳；双联工艺增碳；炉前铁水包随流增碳。

    石墨化增碳剂产品使用方法：

    在电炉底部放置炉料三分之一后将计算好的产品放置在炉料上，（炉中放一部分料后放增碳剂）然后把剩余炉料按要求放在上面，如上面的炉料较大时应把一些较碎的炉料压在增碳剂上，以防止漂浮影响吸收率。增碳剂加入量是金属量的1-3，用户也可根据产品生产质量要求自行调整。增碳剂的特点是碳在铁液中吸收效果好，不返渣，使用增碳剂可大幅度降低铸件生产成本。

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 高。

    2、吸收率高, 根据使用方法吸收率 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， 低0.02。氮份低，100ppm以下。

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

增碳剂使用方法：

    5吨以上电炉，推荐分散加入法。根据含碳量要求按配料比将增碳剂与金属炉料随其它配料一同加入电炉中下部位。

    使用2-3吨左右中频感应电炉，推荐集中加入法：在炉内先熔化部分铁水或剩余少量铁水时，将需要配加的增碳剂一次性加在铁水表面，并立即添加金属炉料，将增碳剂全部压入铁水中，使增碳剂与铁水充分接触。

    使用小型中频电炉，如原料单一稳定，推荐将增碳剂集中加在炉子下部；原料夹有生铁等高碳物质的，则推荐增碳剂微调：即钢或铁水熔化后调整含碳，可以加在钢或铁水表面，通过熔炼时铁水的涡流搅拌使本产品溶解吸收。

增碳剂具备特性

    1.颗粒大小适中，孔隙度大，吸收速度快。

    2.化学成分纯净，高碳、低硫、有害成分极微，吸收率高。

    3.产品石墨晶体结构好，提高原铁液的形核能力。在孕育中增加球墨铸铁的墨球数量，在电炉铁液中增加石墨晶核，细化、均匀化石墨在铸件中的分布。

    4.性能优异、稳定；选用合适的增碳剂有助于降低冶炼生产成本，提高冶炼金属及铸件的质量。

增碳剂规格：

    0.5-1 1-2 2-4 4-6 6-8 8-10 1-3 3-5 5-8mm等多种规格，可按客户要求调整生产。

增碳剂包装方式：

    25kg/袋，双层编织代包装，也可使用吨袋包装，具体包装要求可按客户要求调整生产。

Recarburizerprofile:
Carburizing agent, there are many kinds of raw materials, production processes are different, wood carbon, carbon coal, coke, graphite, etc., in which various categories and a lot of small type. High quality carburizing agent generally refers to after graphite carburant, in under the condition of high temperature and carbon atoms arranged in graphite morphology, so called for graphitization. Graphite can reduce the content of impurities in the carburant carburant, increasing carbon content, reducing sulfur content. Suitable for steel and iron casting carburizing (Lian Gang). With high carbon and low sulfur, low water content and low cost and high cost performance.
At present, there are 3 kinds of commonly used carburetant:
First, graphite powder, graphite electrode is a vacuum powder processing.
The two is after petroleum coke, some domestic steel plant, is used after petroleum coke, made of carburizing agent.
Three is the graphitized petroleum coke, is also used in steelmaking, recarburizer used.
Recarburizer purposes:
Applicable smelting process:
Induction furnace carburizing furnace; cupola furnace carbonization; process by double carbon furnace; ladle stream carburizing.
Graphitization recarburizer product usage:
Placed at the bottom of the furnace, after one third of the burden will calculate good product placed in charge. (after the furnace put part of the material put recarburizer) and the remaining charge according to the requirements in the above, such as the above charge large should put some more crushing burden of pressure on the carburant, to prevent the floating effect absorption rate. Recarburizer addition amount is 1-3 of metal, the user can also adjust itself according to the requirements of the quality of the products. Carburant characteristics is carbon in liquid iron absorption effect is good, does not return slag, recarburizing agent can greatly reduce the cost of castings.
Recarburizer features:
1, high fixed carbon, high absorption rate, low sulfur, low nitrogen and in the absorption speed faster than similar graphite carburant, and adsorption of furnace wall, fully absorb the residue free, the price is lower than the similar sulfur is less than 0.05 following the graphitized carbon agent, the highest price.
2, high absorption rate, according to the use of the method to achieve the highest absorption rate can reach more than 90.
3 absorption speed, faster than similar graphite carburant absorption rate, adsorption of furnace wall and no residue, furnace carbon absorption speed advantage is more obvious.
4, sulfur share is low, below 0.05, the lowest 0.02. Low nitrogen, 100ppm
5, the high cost, in the review of similar graphitization recarburizer (sulfur in the most advantageous price is less than or equal to 0.05).
Recarburizer method of use:
.5 tons of electric furnace, recommended to join the law. According to the carbon content requirements according to ingredients than the carburant and metal charge with other ingredients to join electric furnace bottom part.
2. Use 2-3 tons of medium frequency induction furnace, recommended concentration to join method: in the furnace first partially melted iron or remaining a small amount of hot metal will require adding carburizing agent is added at a time on the surface of the molten iron, and immediately add metal charge, press the carburant all into molten iron, can increase the carbon agent and good contact with the molten iron.
. use a small intermediate frequency electric furnace, such as material single stability, recommended recarburizer concentrated in the bottom of the furnace; raw materials are cast iron and high carbon material folder, it is recommended that the carburant fine-tuning: steel or iron melting after adjustment carbon can in steel or iron on the surface, by melting molten iron of the vortex stirring to dissolve the product absorption.
Have the characteristics of high quality carburizing agent
1 the particle size is moderate, the porosity is big, the absorption speed is fast.
2 the chemical composition of pure, high carbon, low sulfur, extremely harmful ingredients, high absorption rate.
3 the graphite crystal structure of the product is good, and the nucleation ability of the original liquid iron is improved. Increase the number of nodular cast iron in the inoculation of nodular graphite nucleation, increase in the electric furnace molten iron. Distribution of fine and uniform fossil ink in the casting.
4 excellent performance and stability. Choose appropriate recarburizer helps reduce smelting production cost, improve the quality of metal smelting and casting.
