Abstract
PROCEDURE FOR THE DEPHOSPHORIZATION, DESULFURIZATION AND DENITRIFICATION OF IRON INGOTS, WHICH CONTAIN CHROME. IT CONSISTS TO CONTACT THE CAST IRON WITH A SLAG WITH CONTENT OF CAO BETWEEN 10 AND 40 PER100, OF UGLY BETWEEN 5 AND 40 PER100, CAFE2 BETWEEN 40 AND 80 PER100 AND SIO2 HIGHER THAN 3. THE CARBONE CONTENT OF THE IRON CAST IS MAINTAINED IN PERCENTAGES LESS THAN 5 PERCENT. VARIOUS VARIANTS ARE OBTAINED BY MODIFICATION OF THE PERCENTAGES OF THE VARIOUS COMPONENTS OF SLAG AND BY SUBSTITUTE OF OXIDES OF IRON BY NICKEL OXIDE, AS WELL AS THE CONTENT OF IRON. MOLTEN.
