By scrap — an ore process

___A shief metallurg of «ТехноИнжениринг» company write:
___By scrap — an ore process open-hearth production main forming metallic shicht is fluid cast iron (55…75%), but rest its part is hard steel scrap. For oxidation of the admixtures of cast iron in this process is required vastly greater amount of oxider, than in scrap — a process, in consequence of greater share of cast iron. The Much of oxider is given in the manner of iron ore, as defines the name of the process (scrap — ore).
___Except scrap and scrap — an ore varieties of the open-hearth process on type of shicht, the known scrap — coal and ore processes. Skrap — a coal process lead on 100% hard of scrap with additive of coke and coal for relief of the melting and removing the admixtures carbon — containing material. The Ore process lead on 100% fluid cast iron without additives of scrap. Both these varieties are compelled. Are they At present researched possibility of the undertaking the process, reminding scrap — coal, in oxygen converter.
___In dependencies from type refractory material, used for fireproof to open-hearth furnace, exists two varieties of the open-hearth process — tart and the main. The Tart open-hearth furnaces fireproofing the dynas by brick, welded on under execute from quartz sand or quartzke (main forming SiO2 with small contents of the admixtures). In these stove possible to have only tart slags, which define the nature and particularities of the process. Phosphorus does not delete in tart stove and sulphur so source shicht must not contain these admixtures. Since such shicht expensive, in tart stove melted only qualitative steels. Usually tart stove has a small capacity and work scrap — a process. At present tart open-hearth furnaces have a small spreading.
