Testing conducted for new materials, such as refractory core and mold coatings, charge materials and deoxidizing compounds.
So, electroslag method, which did not find practical application in production of titanium and its alloys in airspace and military fields, is successfully used for production of ferrotitanium, because requirements to ferrotitanium, designed for deoxidizing and alloying of steel, alloys and cast iron, as wel as for production of welding materials, do not at all regulate content in it of such harmful impurities as hydrogen, oxygen, and nitrogen (Table 1).
6 cm were wiped with acetone and processed through alkaline cleaning, deoxidizing, and conversion coating steps according to the conditions described elsewhere.
Mainly as a ferroalloy, manganese remained in demand for steelmaking because of its role in sulphur-fixing, deoxidizing, and alloying.
Such chips, as a rule, are sent to the ore heat-treating furnaces for melting of ferrotitanium and are used for pressing of briquettes used in the process of deoxidizing of steel.
Other methods of deoxidizing copper during melting, while effective, had tended to increase the hydrogen content of the melt.
Overall manganese demand was dominated by steelmaking where, as has been the case so far throughout the 20th century, economics and metallurgy make manganese a key element because of its sulphur-fixing, deoxidizing, and alloying behavior.
So, technological scheme of producing especially low-carbon steels obligatory includes processes of degassing, deoxidizing, and refining of the semi-finished product, molten in the steel-melting unit.
To control hydrogen and nitrogen within the melting process, he suggested minimizing the holding, avoiding deoxidizing in the furnace, tapping fast and keeping the scrap and alloys as low as possible.
