___In consequence of increasing of the contents in open-hearth slag oxides ferric, process of the removing the sulphur in stove will develop is limited. Usually factor of the sharing the sulphur (S)/[S] forms 3…10 units. Considering smaller amount of the slag in contrast with amount of the metal, possible see that before half put into stove of the sulphur, but sometimes and more — remains in steels. In this connection removing the sulphur reasonable to conduct outside of stove in scoop before potting of cast iron in stove and after issue become in scoop. In these cases condition of the removing the sulphur more favourable, since applicable slag contains little oxideses ferric.
___In open-hearth furnace, for more full removing the sulphur, can be an aplying syntetic slag, consisting of CaO and Al2O3. Follows also to check the contents of the sulphur in fuel, in coke gas and fuel oil particularly. Applicable clear is subjected to for open-hearth furnaces coke gas, at contents of the sulphur falls before 2 grams on cubic metre. Residing usually in scrap «hereditary» admixture (copper, nickel and others) on move open-hearth smelting trunks do not delete. Practically also does not delete available in some cast iron bad admixture — an arsenic.
___The Reaction of oxidations of carbon of the metallic bath differs from the other reaction of the oxidation of the admixtures by forming the gaseous products with high contents CO. The Separation of these products from bath creates the effect of the boiling with separation on most of its surfaces of the bladders (the gaseous products of the oxidation of carbon). The surface of the contact of the metal sharply increases at boiling with slag, on which go the reactions of the oxidation (and transition in slag) of the other admixtures of the bath. It Is Provided also mixing of metal, justifying its composition and temperature. The much dissolved goes in bubble CO in metal gas (the nitrogen and hydrogen), is relieved surfacing from bath non-metallic cut-in, occurring together with rising bladder.
