1. Förfarande för förängning av tillsatsmaterial i en metallsmälta genom att använda ett kärl, som uppvisar minst en med minst ett tillsatsmaterial fyllt kammare, varvid kammaren uppvisar flera öppningar för att mata metallsmältan ur kärlet in i kammaren och för att avlägsna det förängade tillsatsmaterialet ur kammaren in i metallsmältan och varvid kammarens geometriska arrangemang och storlek och öppningar-nas totalarea i förhällande tili metallsmältans mängd T i ton och element, som ingär i metallsmältan och som skall bindas med tillsatsmaterial, ästadkommer en förängningstid t i sekunder, kännetecknat av att förängningstiden bestäms enligt formeln t = 68 x T°'22 x A, varvid A betyder en koefficient beroende av tillsatsmaterialet.
2. Förfarande enligt patentkravet 1, kännetecknat av att dä magnesium förängas i metallsmältan som tillsatsmaterial justeras koefficienten A tili ett värde 0,5-1,5.
3. Förfarande enligt patentkravet 1, kännetecknat av att dä kalcium förängas i metallsmältan som tillsatsmaterial justeras koefficienten A tili ett värde 0,7-1,2.
4. Förfarande enligt patentkravet 1, kännetecknat av att dä litium förängas i metallsmältan som tillsatsmaterial justeras koefficienten A tili ett värde 0,4-1,1. Il
