Abstract
Procedeul de introducere a magneziului metalic nealiat în fanta topita de turnatorie, conform inventiei, prevede preamestecarea acestuia cu un feroaliaj cu continut de 30...75% Si, de Mg si adaosuri de pamînturi rare, de maximum 2% Ca si 1,5% Al, introducerea amestecului omogenizat fin granulat într-un recipient deschis din tabla subtire de otel si imersarea recipientului cu mijloace uzuale în topitura de fonta. în scopul optimizarii conditiilor de tratare a toapiturii de fonta, foloseste amestecul constituit din 4..40% si, de preferinta, 4...25% Mg metalic cu granulatie peste 90% si 6,4 mm si rest feroaliaj cu continut de 3...12% Mg si 0,1...2,5% Ce cu granulatie peste 90% de 9,5 mm.
