Q=K•(C1 - C2),
где Q - удельный расход нейтрального газа от момента достижения в расплаве содержания углерода в пределах 0,02 - 0,06%, м3/т расплава;
С1 - содержание углерода в расплаве перед началом подачи нейтрального газа с удельным расходом Q, %;
С2 - необходимое содержание углерода в расплаве после окончания подачи нейтрального газа с удельным расходом Q, %;
К = (60 - 130) - эмпирический коэффициент, учитывающий закономерности удаления из расплава окиси углерода пузырьками нейтрального газа, устанавливаемый в прямой зависимости от значения разницы (С1 - С2), м3/%•т расплава.1. Method of steel smelting in the converter, including blowing the melt with oxygen from the top through the tuyere and neutral gas from the bottom through bottom tuyeres during the whole melting, changing the flow rate of the neutral gas, determining the chemical composition of the melt, measuring its temperature, pouring the melt into the casting ladle and feeding deoxidizers into it characterized in that upon reaching the carbon content C 1 in the melt - in the range of 0.02 - 0.06% in the temperature range 1680 - 1720 o C with oxygen purge was stopped and continued purging with inert gas with a specific flow m, depending on the defined
Q = K • (C 1 - C 2 ),
where Q is the specific consumption of neutral gas from the moment the carbon content in the melt is in the range of 0.02 to 0.06%, m 3 / t of the melt;
C 1 is the carbon content in the melt before the start of the supply of neutral gas with a specific flow rate Q,%;
C 2 - the required carbon content in the melt after the end of the supply of neutral gas with a specific flow rate Q,%;
K = (60 - 130) is an empirical coefficient that takes into account the regularities of removal of carbon monoxide from a melt by bubbles of neutral gas, which is directly dependent on the difference value (C 1 - C 2 ), m 3 /% • t of melt.
