Abstract

Способ плавления содержащего железо исходного сырья в реакторе, содержащем шлаковую ванну, включающий создание тепловых и восстановительных условий в по крайней мере одной зоне восстановления ванны путем вдувания топлива (восстановителя) и содержащий кислород газа через по крайней мере одну верхнюю погруженную фурму. Исходное сырье загружают в реактор вместе с дополнительным и с флюсом в по крайне мере одну зону восстановления или в прилегающую к ней зону таким образом, чтобы они были подвергнуты восстановительному плаванию, причем в качестве дополнительного восстановителя применяют уголь. Скорость вдувания кислорода и топлива (восстановителя) регулируют с целью добиться требуемых, достаточных для восстановления условий путем подачи вдуваемого газа с содержанием кислорода от примерно 40% до примерно 100%, что достаточно для обеспечения сгорания от примерно 40% до примерно 50% топлива (восстановителя), а вырабатываемые в процессе плавления окись углерода и водород, а также угольную пыль, выносимую из ванны газообразными продуктами сгорания, подвергают дожиганию в реакторе, обеспечивая достаточное нагревание ванны, предотвращая при этом повторное окисление содержимого ванны.
