A following part of period of the boiling

___A shief metallurg of «ТехноИнжениринг» company write: 
___A following part of period of the boiling to open-hearth furnace, after waxing, conduct without additives on bath. The Boiling occurs in consequence of oxidize characteristic atmosphere stove (the clean boiling). The Separation of the bladders CO (the products of the removing of carbon) causes mixed of baths and its having warmed up before necessary metal for issue of the temperature. At the end of the period of the boiling bath is cleaned from dissolved nitrogen and hydrogen, not metallishe of the cut-in and reaches the givenned composition and temperature. Checking the composition of the metal on contents of carbon, manganese, phosphorus and sulphurs conduct the express by analysis selected in this period of the tests from bath, checking the temperature — a short submersions in bath of the thermocouples.
___In end of smelting trunks by steels, in open-hearth furnace conduct partial (preliminary) outoxiding of metal. Usually for this use ferro-alloy, containing low concentrations of the element with high relationship to oxygen — silicon (the poor ferrosilicon with 12…19% Si), as well as ferro-alloy, containing weaker outoxider — an ferromanganese (beside 75% manganese). In row of the events use the complex outoxiders, containing simultaneously silicon and manganese, or more complex composition. After preliminary of outoxiding and small endurance, metal release from stove in steelpoured scoop or in several scoops.
___A main admixture, deleted from metal basically open-hearth process are silicon, manganese, carbon, phosphorus and sulphur. At silicon, manganese and phosphorus move over to type oxides in slag, carbon forms the gaseous oxideses, moving over to atmosphere stove, but sulphur moves over to slag in the manner of join or groups with calcium and with magnesium and manganese partly. From enumerated element by most relationship to oxygen possesses silicon, which acidifies in the main open-hearth furnace nearly completely as far back as period of the melting on reaction with oxygen of atmosphere or FeO slag, similar reaction in oxygen converter.
