Claims (9)

1. Способ производства передельного чугуна, в котором железную руду восстанавливают в восстановительной шахте (1) до губчатого железа, которое затем вводят в верхнюю часть плавильного газификатора (3) и плавят в нем с помощью газифицирующего агента, который также вводят в верхнюю часть плавильного газификатора (3), и кислородсодержащего газа с образованием жидкого передельного чугуна, при этом одновременно образуется восстановительный газ, который выводят из верхней части плавильного газификатора (3) и подают в восстановительную шахту (1) для восстановления оксида железа, отличающийся тем, что губчатое железо, вводимое в плавильный газификатор (3), имеет высокую степень металлизации, превышающую 90%, при этом в плавильный газификатор вводят дополнительно оксид железа для уменьшения степени металлизации.1. Method for the production of pig iron, in which iron ore is reduced in a reduction shaft (1) to sponge iron, which is then introduced into the upper part of the melting gasifier (3) and melted therein using a gasification agent, which is also introduced into the upper part of the melting gasifier (3), and oxygen-containing gas to form liquid pig iron, while reducing gas is simultaneously formed, which is removed from the upper part of the melter gasifier (3) and fed to the reduction shaft (1) to reduction of iron oxide, characterized in that the spongy iron introduced into the melting gasifier (3) has a high metallization degree in excess of 90%, while iron oxide is additionally introduced into the melting gasifier to reduce the degree of metallization. 2. Способ по п.1, отличающийся тем, что используют куски оксида железа в виде железной руды.2. The method according to claim 1, characterized in that use pieces of iron oxide in the form of iron ore. 3. Способ по п.1 или 2, отличающийся тем, что оксид железа вводят через питающий трубопровод (4), предназначенный для введения газифицирующего агента.3. The method according to claim 1 or 2, characterized in that the iron oxide is introduced through the feed pipe (4), intended for the introduction of a gasifying agent. 4. Способ по одному из пп.1-3, отличающийся тем, что степень металлизации губчатого железа, выходящего из восстановительной шахты (1), превышает 92%.4. The method according to one of claims 1 to 3, characterized in that the degree of metallization of the sponge iron leaving the recovery shaft (1) exceeds 92%. 5. Способ по одному из пп.1-4, отличающийся тем, что путем добавления оксида железа степень металлизации носителей железа, вводимых в плавильный газификатор (3), уменьшают примерно до приблизительно 88% или даже до меньшего значения.5. The method according to one of claims 1 to 4, characterized in that by adding iron oxide, the metallization degree of the iron carriers introduced into the melting gasifier (3) is reduced to approximately 88% or even lower. 6. Способ по одному из пп.1-5, отличающийся тем, что по меньшей мере часть кислородсодержащего газа вдувают в зону купола плавильного газификатора (3).6. The method according to one of claims 1 to 5, characterized in that at least part of the oxygen-containing gas is blown into the zone of the dome of the melting gasifier (3). 7. Способ по одному из пп.1-6, отличающийся тем, что в плавильный газификатор (3) в зоне купола подают через питающий трубопровод (4), предназначенный для введения газифицирующего агента, углеродсодержащую подрешетную фракцию.7. The method according to one of claims 1 to 6, characterized in that the carbon-containing sublattice fraction is fed into the melting gasifier (3) in the dome zone through a supply pipe (4) for introducing a gasifying agent. 8. Способ по одному из пп.1-7, отличающийся тем, что в плавильный газификатор (3) загружают смесь оксида железа и губчатого железа.8. The method according to one of claims 1 to 7, characterized in that a mixture of iron oxide and sponge iron is loaded into the melter gasifier (3). 9. Способ по одному из пп.2-8, отличающийся тем, что в плавильный газификатор загружают подрешетную фракцию оксида железа в качестве кускового носителя оксида железа.9. The method according to one of claims 2 to 8, characterized in that the sub-sieve fraction of iron oxide is loaded into the melter gasifier as a lump carrier of iron oxide.
