Abstract
Pronalazak se odnosi na postupak uklanjanja bizmuta iz istopljenog olova pomoću magnezijuma i kalcijuma, prema postupku se magnezijum i kalcijum unesu u obliku komada dve legure magnezijum-kalcijum, jedna legura sadrži više magnezijuma, a druga legura sadrži više kalcijuma i svaka legura je u stanju rastopa, na temperaturi manjoj od 650В°C, poželjno manjoj i od 600В°C. Temperature tečnih legura poželjno su približne, razlika izmedju njih nije veća od 20В°C. Posebno efikasan postupak dobijen je sa legurom magnezijum-kalcijum, bliskom eutektičkoj sa 16.2% (tež.) kalcijuma i koja sadrži 12 do 25% kalcijuma, a legura kalcijum-magnezijum sadrži izmedju 60 i 80% kalcijuma. Pronalazak omogućuje brzo uklanjanje bizmuta i daje mogućnosti za podešavanje odnosa Ca/Mg u toku postupka.[The invention concerns a method for eliminating bismuth from molten lead with magnesium and calcium, which consists in inputting magnesium and calcium in the form of lumps of two Mg-Ca alloys, one containing predominantly Mg, the other containing predominantly Ca, each having a Liquidus temperature lower than 650В°C, and preferably less than 600В°C. The Liquidus temperatures of the two alloys are preferably close to less than about 20В°C. A particularly efficient treatment is obtained with a Mg-Ca alloy close to the eutectic alloy at 16.2 wt. % of calcium and containing 12 to 25 % of calcium and a Ca-Mg alloy containing between 60 and 80 % of calcium. The invention enables fast elimination of bismuth and adjustment of the Ca/Mg ratio during treatment.
