硅铁
硅铁简介:硅铁是以焦炭、钢屑、石英(或硅石)为原料,用电炉冶炼制成的。硅和氧很容易化合成二氧化硅。所以硅铁常用于炼钢作脱氧剂,同时由于SIO2生成时放出大量的热,在脱氧同时,对提高钢水温度也是有利的。硅铁作为合金元素加入剂。广泛用于低合金结构钢、合结钢、弹簧钢、轴承钢、耐热钢及电工硅钢之中,以外硅铁在铁合金生产及化学工业中,常用作还原剂。含硅量达95%--99%。纯硅常用制造单晶硅或配制有色金属合金。 用途: 硅铁在钢工业、铸造工业及其他工业生产中被广泛应用。硅铁是炼钢工业中必不可少的脱氧剂。炬钢中,硅铁用于沉淀脱氧和扩散脱氧。砖坯铁还作为合金剂用于炼钢中。钢中添加一定数量的硅,能显著提高钢的强度、硬度和弹性,提高钢的磁导率,降低变压器钢的磁滞损耗。一般钢中含硅0.15%-0.35%,结构钢中含硅0.40%~1.75%,工具钢中含硅0.30%~1.80%,弹簧钢中含硅0.40%~2.80%,不锈耐酸钢中含硅3.40%~4.00%,耐热钢中含硅1.00%~3.00%,硅钢中含硅2%~3%或更高。高硅硅铁或硅质合金在铁合金工业中用作生产低碳铁合金的还原剂。硅铁加入铸铁中可作球墨铸铁的孕育剂,且能阻止碳化物形成,促进石墨的析出和球化,改善铸铁性能。此外,硅铁粉在选矿工业中可作悬浮相使用,在焊条制造业中作焊条的涂料;高硅硅铁在电气工业中可用制备半导体纯硅,在化学工业中可用于制造硅酮等。在炼钢工业中,每生产一吨钢大约消耗3~5kg75%硅铁。
Introduction: ferrosilicon is fesi coke and steel scurf, quartz(or silica) as raw material and using made of electric n and oxygen easily dissatisfied silica. So ferrosiliconoften used in steelmaking as deoxidizer, at the same time as SIO2is formed give off a lot of heat, in the same time, to improvedoxycycline steel temperature is also beneficial. Ferrosilicon asalloy elements join agent. Widely used for low alloy steels, close"steel, spring steel, bearing steel, heat-resistant steels andelectrician silicon-steel outside of fesi in ferroalloy productionand chemical industry, commonly used as a reductant. Volumecontaining silicon 95% - 99%. Pure silicon common manufacturingmonocrystalline silicon or configuration non-ferrous metal : in the steel industry, casting ferrosilicon industrial andother industrial production has been widely used. Ferrosilicon issteelmaking industry indispensable deoxidizer. Ju, ferrosiliconused to sediment steel deoxidization and diffusion -drying alloy agent used in iron as steelmaking. Add a certainamount of steel, can significantly improve the silicon steelstrength, hardness and flexibility, improving steel magneticconductivity, reducing transformer steel hysteresis ry steel contains silicon 0.15% - meet in 0.40% containingsilicon, structural steel, steel contains 1.75% ~ 0.30% ~ 1.80%,spring steel silicon in 2.80% 0.40% ~ of silicon steel, stainlessacid contained in silicon 4.00%, heat-resisting steel 3.40% ~ in1.00% ~ 3.00%, containing silicon in silicon steel containingsilicon 2% ~ 3% or higher. High silicon ferrosilicon or siliceousalloy in ferroalloy industry used to produce low carbon ferroalloyreductants. Cast of fesi join inoculants of ductile iron, and canprevent carbide, promote the formation of graphite spheroidization,improve the separation and cast iron performance. In addition,mineral powder in ferrosilicon industrial of use, the suspendedphase of electrode welding manufacturing coating; High siliconferrosilicon in electrical industrial available in the preparationof pure silicon semiconductor, in the chemical industry can be usedin the manufacture of silicone, etc. In steelmaking industry, oneton to every production drain about 3 ~ 5kg75 % ferrosilicon.
