Detailed Description

Silicon-iron is made up of burnt carbon, steel bits and quartz(silex) which be smelt with electric cooker. Silicon and oxygen can be easily composed into silicon dioxide, so it is always used as oxigenate medicament in steel-making. At the same time because when SiO is made there gives out a mass of heat, at the same time of oxigenate, it can increase molten steel temperature and decrease energy consume. As alloy element additives silicon-iron is mostly used in low alloy fabric steel, alloy steel, spring steel, 　　axletree steel, refractory steel and electrician silicon steel. In iron alloy and chemical industry silicon-iron is often used as reducer. Pure silicon with 95-99% silicon content is often used to make single crystal silicon or confect colored metal alloy. The use 　　It abroadly apply in steel industry, foundry industry and other insudtry. Silicon-iron is an absolutely necessarily oxigenate medicament in steel-making industry. It is used to deposit oxigenate and diffuse oxigenate. It is used as alloy medicament too. Appending some silicon in steel can obviously improve steel intensity, rigidity and elasticity, improve steel magnetism conductance, reduce transformer steel magnetism sluggish waste. Common steel contains silicon 0.15%-0.35%,fabric steel contains silicon 0.40%-1.75%, facility steel contains silicon 0.30%-1.8%, spring steel contain silicon 0.40%一2.80%, stainless& acid less steel contains 3.4%-4.0%, refractory steel contains 1.0%-3.0%, silicon steel contains silicon 2.0%-3.0% or higher. 　　High silicon-iron or silicon alloy is used as reducer to produce low carbon iron alloy in iron alloy industry. Silicon-iron can be used as gestation medicament of ball-ink casting iron by appending it into the casting iron, and it can prevent forming carbide,boost separateing out plumbaginous and ballizing and improve cast-iron capability. Besides silicon-iron powder can be suspended in mill-run industry, as welding rod dope in welding rod industry. High silicon-iron is used to produce semiconductor pure silicon in electric industry and make silicon-ketone in chemical industry.
