Abstract

Doğru akım elektrik ark fırınında bulunan fırın potasının (A) belirli oranlarda bor taşıyıcı hammaddeleri (borik asit, bor, boraks ve susuz bor oksit), demir ve demir oksit taşıyıcı hammaddeleri (düşük silisli hematit cevherleri, demirli haddehane artıkları, metalik demir), redükleyici madde olarak odun kömürünü ve fırın içerisinde yoğunluğu azaltmak ve sinter oluşturmamak için kullanılan tahta talaşını içeren şarjla (4) doldurulması ve şarjın (4) doğru akım fırınında ark oluşturularak ergitilerek ferrobor üretilmesidir. Üretilen ferrobor içerisinde bulunan karbon miktarının az olması nedeniyle curuf oluşmamaktadır bu da bor kazanım verimini %98'e çıkarmaktadır.Boron carrier raw materials (boric acid, boron, borax and anhydrous boron oxide), iron and iron oxide carrier raw materials (low silica hematite ores, ferrous rolling mill residues, metallic iron), reducer Filling the charcoal as material and the charge (4) containing wood chips used to reduce the density in the furnace and not to form sinter, and the charge (4) is melted in a direct current furnace to produce ferrobor by melting it in an arc. Since the amount of carbon in the produced ferroboron is low, there is no slag formation, which increases the boron recovery efficiency to 98%.
