Abstract

Предложен способ плавления рудных минералов, содержащих железо, титан и ванадий, так что исходное содержание каждого из указанных элементов известно, в электрической плавильной печи (11), имеющей вмещающую емкость (12) с внутренним пространством, расположенным вокруг центральной оси (X), выполненную с возможностью наклонения ее путем поворота в плоскости наклонения, в которой лежит упомянутая центральная ось (X). Способ содержит операции подачи в упомянутую электрическую плавильную печь (11) упомянутых рудных минералов и вспомогательных материалов с подачей электрической энергии до тех пор, пока не будут достигнуты мощность в установившемся режиме работы (Pmax) и температура установившегося режима работы, составляющая по меньшей мере 1450°С; поддержания упомянутой температуры установившегося режима работы для получения в качестве продуктов этого плавления рудных минералов жидкого чугуна (G), содержащего ванадий, и жидкого шлака (S), содержащего оксид титана, при этом количество ванадия в жидком чугуне (G) составляет по меньшей мере 75% от известного количества ванадия в исходных рудных минералах и количество оксида титана в жидком шлаке (S) составляет по меньшей мере 90% от известного количества оксида титана в исходных рудных минералах, и при этом содержание упомянутого оксида титана в жидком шлаке (S) составляет по меньшей мере 40% по массе, раздельный спуск жидкого шлака (S) путем наклонения вмещающей емкости (12) в первом направлении и выпуск жидкого чугуна (G) путем наклонения вмещающей емкости (12) во втором направлении.A method is proposed for melting ore minerals containing iron, titanium and vanadium, so that the initial content of each of these elements is known in an electric melting furnace (11), which has an enclosing capacity (12) with an internal space located around the central axis (X), with the possibility of inclining it by turning in the plane of inclination in which the said central axis (X) lies. The method comprises supplying said ore minerals and auxiliary materials with electric power supply to said electric melting furnace (11) until steady state power is reached (Pmax) and steady state temperature is at least 1450 ° WITH; maintaining the above-mentioned steady-state operating temperature to obtain, as the products of this melting ore minerals, liquid iron (G) containing vanadium and liquid slag (S) containing titanium oxide, while the amount of vanadium in liquid iron (G) is at least 75 % of the known amount of vanadium in the original ore minerals and the amount of titanium oxide in the liquid slag (S) is at least 90% of the known amount of titanium oxide in the original ore minerals, and the content of the mentioned oxide Ana in liquid slag (S) is at least 40% by mass, separate descent of liquid slag (S) by tilting the containing capacity (12) in the first direction and discharging liquid iron (G) by tilting the containing capacity (12) in the second direction .
