Изобретение относитс к области металлургии , в частности к производству лигатур дл легировани жаропрочных сталей и чугупов .This invention relates to the field of metallurgy, in particular to the production of master alloys for the alloying of heat-resistant steels and cast iron.
Известна лигатура следующего состава, вес. %:Known ligature of the following composition, wt. %:
Молибден55,0Molybdenum55,0
Медь2,5Copper2,5
Кремний2,0Silicon2.0

Недостаток известной лигатуры заключаетс в том, что при выплавке жаропрочных сталей и чугунов, легированных молибденом и медью (например стали ЭП 943) необходимо дополнительпо вводить в металл электролитическую медь.A disadvantage of the known ligature is that when smelting high-temperature steels and cast irons alloyed with molybdenum and copper (for example, steel EP 943), it is necessary to additionally introduce electrolytic copper into the metal.
Медь легкоплавка и быстро раствор етс , а известна лигатура плавитс при 1900°С и дл ее растворени пеобходим большой промежуток времени. В результате большой разности скоростей растворени продолжительность плавки «возрастает, а металл получаетс неоднородным.Copper is low-melting and dissolves quickly, and a known ligature melts at 1900 ° C and a long time is needed to dissolve it. As a result of the large difference in dissolution rates, the duration of the melt increases, and the metal is non-uniform.
Ири выплавке стали с использованием известной лигатуры необходимое содержание молибдена (2,0%) и меди (2,56) устанавливаетс через 23 мин.At steel smelting using a known alloy, the required content of molybdenum (2.0%) and copper (2.56) is established after 23 minutes.
Иредложеина лигатура отличаетс тем, что, с целью, равномерного распределени элементов в легируемом металле и ускорени Iredlozhedeina ligature is characterized in that, in order to uniformly distribute the elements in the alloyed metal and accelerate
