Claims (1)

Способ плавки черновых металлов: заключающийся в том, что перед плавкой в исходный продукт добавляют флюс: состоящий из смеси буры, соды и селитры в соотношении в частях по массе: 100 - буры, 50 - соды и 3 - селитры, а плавку проводят шамотнографитовых тиглях, отличающийся тем, что в состав флюса вводят дополнительные компоненты - серу и фтористый натрий в количестве не менее 2% от массы исходного флюса каждого дополнительного компонента, при этом температуру расплава поддерживают в интервале 1,02-1,07 долей от температуры плавления металла.Method for smelting ferrous metals: consisting in the fact that before melting, a flux is added to the initial product: consisting of a mixture of borax, soda and nitrate in a ratio in parts by weight: 100 - borax, 50 - soda and 3 - nitrate, and chamotte-graphite crucibles are melted , characterized in that additional components are introduced into the flux — sulfur and sodium fluoride in an amount of not less than 2% of the mass of the initial flux of each additional component, while the melt temperature is maintained in the range of 1.02-1.07 fractions of the melting temperature of the metal.
