产品介绍

?

? ? 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,亚博,亚博国际平台,亚博国际pt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亚博,亚博国际平台,亚博国际pt化的增碳剂,在高温条件下,碳原子的排列呈亚博,亚博国际平台,亚博国际pt的微观形态,所以称之为亚博,亚博国际平台,亚博国际pt化。亚博,亚博国际平台,亚博国际pt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。

????增碳剂在铸造时使用,可大幅度增加废钢用量,减少生铁用量或不用生铁。电炉熔炼的投料方式,应将增碳剂随废钢等炉料一起往里投放,小剂量的添加可以选择加在铁水表面。但是要避免大批量往铁水里投料,以防止氧化过多而出现增碳效果不明显和铸件碳含量不够的情况。增碳剂的加入量,根据其他原材料的配比和含碳量来定。不同种类的铸铁,根据需要选择不同型号的增碳剂。增碳剂特点本身选择纯净的含碳亚博,亚博国际平台,亚博国际pt化物质,降低生铁里过多的杂质,增碳剂选择合适可降低铸件生产成本。

?

产品分类

? ? 增碳剂可以用作铸铁增碳剂的材料很多,常用的有人造亚博,亚博国际平台,亚博国际pt、煅烧石油焦、天然亚博,亚博国际平台,亚博国际pt、焦炭、无烟煤以及用这类材料配成的混合料。

? ? ??人造亚博,亚博国际平台,亚博国际pt

? ?各种增碳剂中,品质最好的是人造亚博,亚博国际平台,亚博国际pt。制造人造亚博,亚博国际平台,亚博国际pt的主要原料是粉状的优质煅烧石油焦,在其中加沥青作为粘结剂,再加入少量其他辅料。各种原材料配合好以后,将其压制成形,然后在2500~3000℃、非氧化性气氛中处理,使之亚博,亚博国际平台,亚博国际pt化。经高温处理后,灰分、硫、气体含量都大幅度减少。由于人造亚博,亚博国际平台,亚博国际pt制品的价格昂贵,铸造厂常用的人造亚博,亚博国际平台,亚博国际pt增碳剂大都是制造亚博,亚博国际平台,亚博国际pt电极时的切屑、废旧电极和亚博,亚博国际平台,亚博国际pt块等循环利用的材料,以降低生产成本。熔炼球墨铸铁时,为使铸铁的冶金质量上乘,增碳剂宜首选人造亚博,亚博国际平台,亚博国际pt。

? ????石油焦

? ? 石油焦是目前广泛应用的增碳剂。石油焦是精炼原油得到的副产品,原油经常压蒸馏或减压蒸馏得到的渣油及石油沥青,都可以作为制造石油焦的原料,再经焦化后就得到生石油焦。生石油焦的产量大约不到所用原油量的5%。美国生石油焦的年产量约3000万t。生石油焦中的杂质含量高,不能直接用作增碳剂,必须先经过煅烧处理。生石油焦有海绵状、针状、粒状和流态等品种。海绵状石油焦是用延迟焦化法制得的,由于其中硫和金属含量较高,通常用作煅烧时的燃料,也可作为煅烧石油焦的的原料。经煅烧的海绵焦,主要用于制铝业和用作增碳剂。针状石油焦,是用芳香烃的含量高、杂质含量低的原料,由延迟焦化法制得的。这种焦炭具有易于破裂的针状结构,有时称之为亚博,亚博国际平台,亚博国际pt焦,煅烧后主要用于制造亚博,亚博国际平台,亚博国际pt电极。粒状石油焦呈硬质颗粒状,是用硫和沥青烯含量高的原料,用延迟焦化法制得的,主要用作燃料。流态石油焦,是在流态床内用连续焦化法制得的,呈细小颗粒状,结构无方向性,硫含量高、挥发分低。石油焦的煅烧,是为了除去硫、水分、和挥发分。将生石油焦于1200~1350℃煅烧,可以使其成为基本上纯净的碳。煅烧石油焦的最大用户是制铝业,70%用以制造使铝矾土还原的阳极。美国生产的煅烧石油焦,用于铸铁增碳剂的约占6%。

? ????天然亚博,亚博国际平台,亚博国际pt

? ? 天然亚博,亚博国际平台,亚博国际pt可分为鳞片亚博,亚博国际平台,亚博国际pt和微晶亚博,亚博国际平台,亚博国际pt两类。微晶亚博,亚博国际平台,亚博国际pt灰分含量高,一般不用作铸铁的增碳剂。鳞片亚博,亚博国际平台,亚博国际pt有很多品种:高碳鳞片亚博,亚博国际平台,亚博国际pt需用化学方法萃取,或加热到高温使其中的氧化物分解、挥发,这种鳞片亚博,亚博国际平台,亚博国际pt产量不多、价格高,一般也不作增碳剂;低碳鳞片亚博,亚博国际平台,亚博国际pt中的灰分含量高,不宜用作增碳剂;用作增碳剂的主要是中碳亚博,亚博国际平台,亚博国际pt,但用量也不多。

? ????焦炭和无烟煤

? ? 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。

?

产品用途

?

? ? 增碳剂用于铸造,铸铁、铸钢,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,但是却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。

?

注意事项

?

? ??运输与装卸:在运输过程中,不得用铁钩拖拽,应防止与坚硬物质混装,不可强烈振动、磨擦、踩、 砸,严禁抛掷,应轻装轻卸,以减少包装破碎,影响使用。

? ??储存:应储存于阴凉干燥处,防止内外包装袋破裂,防止受潮和吸附空气中其它物质,影响使用效果。严禁与有毒有害气体或易挥发物质混放,存放要远离污染源。

Product-introduction

?

Recarburizer there are many kinds of raw materials, the production process is different, the woodiness carbon, coal carbon, coke, graphite, which under various classification and there are a lot of small type. High quality carburizing agent generally refers to after graphitization of carburant, under the condition of high temperature, carbon atoms arranged in the microstructure of graphite, so called graphite. Graphite can reduce the content of impurities in the carburant carburant, increasing carbon content, reducing sulfur content.
Carbon in cast use, can greatly increase the amount of scrap, reduce the amount of pig iron or no iron. Furnace feeding way, should be the carbon with scrap charge to put in, add a small dose can choose to add in the hot metal surface. But to avoid large quantities of iron to the feed water, to prevent excessive oxidation and carbonization effect is not obvious and the carbon content of the casting is not enough. Increase the quantity of carbon agent, according to the ratio of other raw materials and carbon content to be. Different types of cast iron, according to need to choose different types of recarburizer. Selection of pure carbon graphite material carburant characteristics, reduce too much impurity in the iron, carburant choose appropriate casting production costs can be reduced.

?

Product-performance

Carburant carburant cast iron can be used as many materials, commonly used with artificial graphite, calcined petroleum coke, natural graphite, coke, anthracite and use this kind of material with the mixture.
? ??Artificial graphite
Carburizing agent, the quality is the best artificial graphite. The main raw material for making artificial graphite is the powdered high quality calcined petroleum coke, in which the asphalt is used as a binder, and a small amount of other auxiliary materials are added. After a variety of raw materials with good, will be pressed forming, and then in 2500 to 3000 degrees Celsius, non oxidizing atmosphere, make the graphite. After high temperature treatment, ash, sulfur, gas content is greatly reduced. As the artificial graphite products are expensive, commonly used artificial graphite foundry by agents are mostly carbon graphite electrode manufacturing chip, and the graphite electrode scrap pieces of material such as recycling, to reduce production costs. Smelting of nodular cast iron, in order to make high quality cast iron metallurgy, carburetant should be the first choice of artificial graphite.
? ??Petroleum coke
Petroleum coke is a widely used carburetant. Petroleum coke is a by-product of refining crude oil, which can be used as raw material to produce petroleum coke, and then get raw petroleum coke. Raw petroleum coke production is less than 5% of the amount of crude oil used. The annual production of petroleum coke in the United States is about 30 million T. Impurity content in petroleum coke is high, can not be directly used as a carburizing agent, must first undergo calcination. Raw petroleum coke has a sponge like, needle like, granular and flow pattern and other varieties. The sponge petroleum coke is produced by the delayed coking process, because of the high content of sulfur and the metal, and usually used as the fuel for calcination, and also can be used as the raw material of calcined petroleum coke. Calcined sponge coke, mainly used for aluminium and used as carburetant. It is a raw material with high content of aromatic hydrocarbon and low impurity content, which is obtained by delayed coking process. This kind of coke has a needle like structure that is easy to break, sometimes referred to as graphite coke, which is mainly used to make graphite electrodes after calcination. Granular petroleum coke is hard granular, is a high content of sulfur and high content of raw materials, the use of delayed coking process, mainly used as fuel. The petroleum coke is produced by continuous coking process in the fluidized bed, which is fine granular, without directional structure, high sulfur content and low volatile matter. Calcined petroleum coke is to remove sulfur, water, and volatile. Calcined petroleum coke at 1200 to 1350 degrees C, can make it become basically pure carbon. The largest user of calcined petroleum coke is aluminium, the anode to make alumina reduction by 70%. The production of calcined petroleum coke, carbon agent for cast iron accounted for about 6%.
? ??Natural graphite
Natural graphite can be divided into two categories, flake graphite and microcrystalline graphite. Microcrystalline graphite with high ash content, generally do not have to iron carburizing agent. There are many varieties of flake graphite: extraction of high carbon flake graphite by chemical method, or heated to a high temperature to which the oxide decomposition, volatilization, the graphite output is not much, the price is high, generally not as carburizing agent; low ash content in high carbon flake graphite, used as a carburizing agent should not be used as a carburizing agent; is mainly of carbon graphite, but the amount is not much.
? ??Coke and anthracite
Electric arc furnace steelmaking process, can add coke or anthracite as carburetant in charging. Due to its high ash content and volatile matter content, induction furnace melting cast iron is rarely used as a carburizing agent.

?

Applications

?

Recarburizer for casting, cast iron, cast steel castings, there will be a requirement for carbon, then carburetant suggests that to increase the carbon content in liquid iron, for example, commonly used in the melting charge for scrap, scrap iron, carbon, iron content is high, but the purchase price of scrap steel is relatively is a day, so increase the amount of scrap, reduce the amount of pig iron, and carbon agent, can play a certain role in reducing the casting cost.

?

caution

?

Transport and handling: in the transport process, not drag hook, should prevent mixed with the solid material, strong vibration, friction, hit, hit, forbid throwing should be lightly armed light discharge, to reduce the breakage of packing, the impact of the use.

Storage: should be stored in a cool and dry place, to prevent internal and external packaging bag break, prevent moisture and adsorption of other substances in the air, affect the use effect. It is strictly prohibited to mix with poisonous and harmful gas or volatile matter, and keep away from the source of pollution.
