宁夏f.c 90-95%炼钢用增碳剂
增碳剂介绍
分炼钢用增碳剂(中华人民共和国黑色冶金行业标准,yb/t
192-2001炼钢用增碳剂)和铸铁用增碳剂,以及其他一些添加材料也有用到增碳剂,譬如刹车片用添加剂,作摩擦材料。增碳剂属于外加炼钢、炼铁增碳原料。优质增碳剂是生产优质钢材必不可少的辅助添加剂。
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。
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石墨化物质,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。
碳剂的使用
在冶炼过程中,由于配料或装料不当以及脱碳过量等原因,有时造成钢中碳含量没有达到顶期的要求,这时要向钢液中增碳。常用的增碳剂有增碳生铁、电极粉、石油焦粉、木炭粉和焦炭粉。转炉冶炼中、高碳钢种时,使用含杂质很少的石油焦作为增碳剂。对顶吹转炉炼钢用增碳剂的要求是固定碳要高,灰分、挥发分和硫、磷、氮等杂质含量要低,且干燥、干净、粒度适中。
其固定碳组分为:
w(c)>96%,挥发分≤1.0%,w(s)≤0.5%,w(水分)≤0.55%,粒度为1一5mm.
粒度太细容易烧损,太粗加入后浮在钢液表面,不容易被钢水吸收。针对感应电炉的颗粒度在0.2-6mm,其中钢和其他黑色金属颗粒度在1.4-9.5mm,高碳钢要求低氮,颗粒度在
0.5-5mm,等等具体需要根据具体的炉型冶炼工件的种类等等细节具体判断和选用。
增碳剂的作用
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。

introduction of
recarburizer
steelmaking recarburizer (ferrous metallurgy industry standard of the people's republic of china, yb/t 192-2001 steel using recarburizer) and cast iron using recarburizer, adding material and some other useful also to carburant, such as brake pads with additives, friction material.recarburizer belongs to plus steelmaking, ironmaking increase carbon materials.high quality recarburizer is essential for production of high quality steel auxiliary additives.
there are many kinds of raw materials about carburant, production process is also different, woodiness carbon, carbon coal, coke, graphite, such as, among them under various classification and there are a lot of small type.high quality recarburizer generally refers to after graphitization of carburant, under the condition of high temperature, carbon atoms arranged in the microstructure of graphite, so called the graphitization.graphitization can lower the content of impurities in the carburant, improve the carbon content of carburant,and reduce sulfur content.

recarburizer used in casting,
can greatly increase the dosage of scrap steel, reduce the dosage
of pig iron or no iron.electric furnace smelting way of feeding,
recarburizer with scrap steel should be burden to put together,
such as small doses of adding can choose to add in the hot metal
surface.but want to avoid mass feeding into the molten iron, in
order to prevent excessive oxidation by carbonization effect is not
obvious and the carbon content of the casting is not
enough.increased carbon agent, the dosage according to the ratio of
other raw materials and carbon content.different kinds of cast
iron, according to need to choose different types of
recarburizer.choose recarburizer characteristics itself pure carbon
graphite material, reduce too much impurity in the iron, carburant
choose appropriate which can reduce the cost of
castings.
