Description
Изобретение относите к черной металлургии , в частности к способам пр мого восстановлени рудных материалов.The invention relates to ferrous metallurgy, in particular to methods for the direct reduction of ore materials.
Кроме черной металлургии изобретение может быть эффективно использовано также в атомной энергетике как средство ути .чизации тепла теплоносител , охлаждающего атом шли реактор.In addition to ferrous metallurgy, the invention can also be effectively used in atomic energy as a means of heat treatment of heat-transfer fluid cooling an atom.
Наиболее близким к изобретению по технической сущности вл етс способ восстановлени рудно-тоиливных окомкованных материалов , содержан1их руду и восстановитель в стехиометрическом соотношении.The closest to the invention to the technical essence is the method of restoring ore-and-ore-containing pelletized materials, containing ore and reducing agent in a stoichiometric ratio.
Процесс осупхествл етс при нагреве материалов до 1340-1500°С 1.The process of ossification is triggered when materials are heated to 1340-1500 ° C 1.
Недостатком этого способа вл етс окисление образующего материала при охлаждении на воздухе, а также необходимость работы при температуре 1300-1500° дл обеспечени требуемой производительности. Работа при такой высокой температуре приводнт к усложнению оборудовани и удорожанию процесса в св зи с необходимостью иснользовани охлаждени в инертном газе, а также пламенных печей, так как существующие (наиболее простые) открытые нечиThe disadvantage of this method is the oxidation of the forming material during cooling in air, as well as the need to work at a temperature of 1300-1500 ° to ensure the required performance. Work at such a high temperature causes the equipment to become more complex and expensive due to the need to use cooling in an inert gas, as well as fiery furnaces, since the existing (simplest) open chambers
сопротивлени не позвол ют длительное врем поддерживать температуру более 1100- 1200°. Кроме того, работа при температуре выше 1100° приводит к получению слипшихс комков железа, размол которых, например дл магнитного отделени пустой породы (шлака) затруднен и требует значительного расхода энергии (до 4000 квт-час/т).resistances do not allow a long time to maintain the temperature over 1100-1200 °. In addition, operation at temperatures above 1100 ° results in adhering lumps of iron, the grinding of which, for example for magnetic separation of waste rock (slag), is difficult and requires significant energy consumption (up to 4000 kWh / t).
Известный способ не может быть использован и в процессах атомной энергетики, где температура теплоносител на выходе из реактора не превышает пока 800° из-за низкой стойкости материалов в услови х интенсивного облучени и активации теплоносител .The known method cannot be used in atomic energy processes, where the temperature of the coolant at the exit of the reactor does not exceed 800 ° so far due to the low resistance of materials under conditions of intensive irradiation and activation of the coolant.
Целью изобретени вл етс увеличение 5 стойкости оборудовани и обеспечение возможности полезного использовани вторичных тепловых ресурсов.The aim of the invention is to increase the durability of the equipment and to ensure the beneficial use of secondary thermal resources.
Дл достижени поставленной цели предлагаетс способ, включающий окомкование и нагрев стехиометрической смеси рудных In order to achieve this goal, a method is proposed, which includes pelletizing and heating of a stoichiometric mixture of ore
