English to Russian Tech/Engineering Metallurgy / Casting способ и установка для производства железа прямого восстановления

The present invention proposes a method for producing direct reduced iron in a vertical reactor having an upper reducing zone and a lower cooling zone, the method comprising the steps of: feeding iron oxide feed material to an upper portion of the vertical reactor, the iron oxide feed material forming a burden flowing by gravity to a material outlet portion in a lower portion of the vertical reactor; feeding hot reducing gas to a lower portion of the reducing zone of the vertical reactor, the hot reducing gas flowing in a counter flow to the burden towards a gas outlet port in the upper portion of the vertical reactor; recovering direct reduced iron at the lower portion of the vertical reactor; recovering top gas at the upper portion of the vertical reactor; submitting at least a portion of the recovered top gas to a recycling process; and feeding the recycled top gas back into the vertical reactor.
