Abstract
Kalciűmkarbid-alapú kéntelenítő keverék, amely legalább 50 tömeg% 0,2mm-nél kisebb szemcsenagyságú kalciűm-karbidőt, 1-20 tömeg% 0,8 mm-nélkisebb szemcsenagyságú pőr alakú vagy granűlátűm alakú magnéziűmőt és5-15 tömeg%, 0,8 mm-nél kisebb szemcsenagyságú pőr alakú vagygranűlátűm alakú alűmíniűmőt tartalmaz, és adőtt esetben tővábbi pőralakú adalékőkat, példáűl meszet-, kalciűm- karbőnátőt,szénvegyületeket és/vagy szemcsebevőnó adalékanyagőkat, legfeljebb 30tömeg% mennyiségben. A kalciűm-karbid szemcsék 25%-nál kisebb részeelőnyösen 0,1 és 0,2 mm közötti szemcsenagyságú. ŕCalcium carbide-based desulfurization mixture containing at least 50% by weight of calcium carbide with a particle size of less than 0.2 mm, 1-20% by weight of powdered or granular magnesium oxide with a particle size of less than 0.8 mm and 5-15% by weight of 0.8 mm contains powdered or granular alumina with a grain size smaller than , and, where appropriate, coarser powder additives, such as lime, calcium carbide, carbon compounds and/or granulation additives, in an amount of up to 30% by weight. Less than 25% of the calcium carbide grains preferably have a grain size between 0.1 and 0.2 mm. ŕ
