Как ВИДНО ИЗ таблицы, при использовании 2, 3 и 4 составов шихт наблюдалс наиболее стабильны электрический релсим, электроды сидели в печи глубоко, расплав из печи выходил легко, был жидкоподвижен.As SPECIFICALLY FROM the table, with the use of 2, 3 and 4 compositions of the charge, the most stable electric relam was observed, the electrodes sat deep in the furnace, the melt came out of the furnace easily, was fluidly moved.
При испытани х 1 состава шихты (прототипа) и запредельных значений предлагаемой шихты (составы 5-10) наблюдалось некоторое расстройство технологического процесса вьшлавки силикомарганца. Расплав в печи в некоторых случа х был в зким, электроды сидели высоко, колошник печи вDuring tests 1 of the composition of the charge (prototype) and the exorbitant values of the proposed mixture (compositions 5–10), there was some disorder in the technological process of melting silicon manganese. The melt in the furnace in some cases was viscous, the electrodes sat high, the furnace's top

прототипа. Опробовано 10 составов шихты, отличающихс друг от друга содержанием компонентов предлагаемой щихты. При этом углекарбидооксидный материал имеет следуюш й химический состав, вес.%; карбид кремни 5-30, оксид кремни 5-20, оксид железа 1- 5, оксид алюмини 0,5-5, оксид кальци 0,5-5, оксид магни 0,5-5, углерод остальное.prototype. Ten compositions of the mixture were tested, differing from each other in the content of the components of the proposed process. At the same time, the carbon carbide oxide material has the following chemical composition, wt%; silicon carbide 5-30, silicon oxide 5-20, iron oxide 1-5, aluminum oxide 0.5-5, calcium oxide 0.5-5, magnesium oxide 0.5-5, carbon else.
Составы шихт и результаты лабораторных .иcпыfaний приведены в таблице.The composition of the mixture and the results of laboratory. Ways given in the table.
результате этого спекалс , ухудшались все технико-экономические показатели .As a result of this speculation, all technical and economic indicators deteriorated.
Таким образом, использование угле- карбидооксидного материала в качестве восстановител в предлагаемом составе Ешхты дл выплавки силикомар- - ганца позвол ет повысить электросопротивление ванны печи, увеличить извлечение окислов марганца и крем- ни ; снизить расход электроэнергии, шихтовых материалов. Кроме того, изобретение позвол ет эффективно лизировать углекарбидооксидные отходы электродных заводов.Thus, the use of a carbide oxide material as a reducing agent in the proposed Eshkhta composition for smelting manganese-silicate makes it possible to increase the electrical resistance of the furnace bath, to increase the extraction of manganese and silicon oxides; reduce the consumption of electricity, batch materials. In addition, the invention makes it possible to efficiently lyse carbon carbide oxide wastes of electrode plants.
