中频炉用增碳剂 0.5-1mm优质增碳剂

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。优质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。

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。

强烈推荐球铁厂家使用本厂低硫低氮石墨增碳剂。

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。

增碳剂使用方法：

①.5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。

②.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。

③.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。

优质增碳剂具备的特性

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。

Recarburizerprofile:

Carburant, there are many kinds of raw materials, production process is different, the woodiness carbon, coal carbon, coke, graphite type, etc., and there are many small categories under which various classification. High quality recarburizer generally refers to after graphitization of carburant, under the condition of high temperature, the microstructure of carbon atoms arranged in graphite, so called the graphitization. Graphitization can reduce the impurity content of a carburant, viscosity increasing carbon content, carbon agent to reduce sulfur content. Apply to cast iron (steel) and grey iron casting carburization. Have high carbon, low sulfur, low water content and the characteristics of low cost and high cost performance.

Recarburizer indicators:

Specification of fixed carbon sulfur % n % % % % ash % moisture volatilize

3-6 mm 98 0.02 0.01 0.5 0.5 0.01

3-6 96 0.03 0.01 0.8 0.7 1 mm

1-5 mm 95 0.05 0.01 1.0 2 1

92 0.05 0.01 1.0 3 2 1-5 mm

Recarburizer purposes:

Melting process shall apply:

Induction furnace furnace carbonization; Cupola furnace carbonization; Duplex process increase carbon; Before the furnace hot metal ladle carbon over flow.

Ductile iron manufacturers are strongly recommended to use this factory low sulfur, low nitrogen graphite recarburizer.

Graphitization recarburizer product usage: in the electric furnace is placed at the bottom of the furnace charge will be calculated after a third good product placed on the furnace charge, (after the furnace put part of the material put recarburizer) and then put the remaining charge according to the requirements above, such as when the burden is bigger, 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, user can also adjust itself according to the product production quality requirement. Recarburizer is characteristic of carbon in liquid iron absorption effect is good, does not return slag, using recarburizer can reduce the cost of castings production.

Recarburizer features:

1, high fixed carbon, high absorption rate, low sulfur, low nitrogen, and on the absorption rate faster than similar graphitization carburant, and adsorption of furnace wall, fully absorbed no residue, price is lower than the similar sulfur is lower than 0.05 following the graphitization of carburant, the highest cost performance.

2 absorption rate is high, according to the method using the highest absorption rate can reach more than 90%.

3 absorption speed, than the similar graphitization recarburizer fast absorption and adsorption of furnace wall, and no residual, furnace increases in carbon absorption speed advantage is more obvious.

Low sulfur, 4 below 0.05%, the lowest 0.02%. N a low, 100 parts per million

5 ultra high performance to price ratio, review the above to the same type of graphitization recarburizer sulfur (0.05) or less price is most advantage.

Recarburizer method of use:

1. 5 tons of electric furnace, scattered recommend joining method. According to carbon content requirements according to ingredients than the carburant and metal furnace charge to join electric furnace bottom part with other ingredients.

(2). Use 2-3 tons of intermediate frequency induction furnace, the recommended concentration to join method: in hot melt furnace part or a small amount of hot metal, the remaining will need with addition of recarburizer one-time to add in the hot metal surface, and add metal furnace charge immediately, to press the carburant all into molten iron, carburant and good contact with the molten iron.

(3). Using a small intermediate frequency electric furnace, such as material single stability, recommend add recarburizer concentrated at the bottom of the furnace; Raw materials with high carbon material of cast iron, the recommended recarburizer fine-tuning: adjusting carbon after the steel or hot metal melting, can be added to steel or iron on the surface, through melting molten iron of the vortex stirring to dissolve the product absorption.

High quality recarburizer with features

1. Particle size, porosity, absorption speed.

2. The chemical composition of pure, high carbon, low sulfur, extremely harmful ingredients, high absorption rate.

3. Good products graphite crystal structure, improve the capability in the shape of liquid iron. Increased in the inoculation of nodular cast iron ball ink quantity, increase in the electric furnace iron graphite crystal nucleus. Refine the fossils, uniform ink distribution in the castings.

4. Excellent performance, stable. Choose appropriate recarburizer helps reduce smelting production cost, improve the quality of metal smelting and casting.

Recarburizer specifications:

1-0.5-1 2 2-4 of 4-6 of 6-8 8-10 1-3 of 3-5 of 5-8 mm and so on the many kinds of specifications, can adjust the production according to customer's request.

Recarburizer packing:

25 kg/bag, double braided packing, also can use tons of bags, specific packaging requirements can be adjusted according to customer requirements production.
