Description
(54) СПОСОБ ПРОИЗВОДСТВА ОФЛЮСОВАННЫХ ОКАТЫШЕЙ В КНПЯЩЕМ СЛОЕ(54) METHOD OF MANUFACTURING OF BREWED INSULATED IN A KNF LAYER
карбонатный скелет. Усвоение шлама зародышами происходит на 90-195%. При увеличении температуры газов на каждые 100°С подачу железосодержаш,его материала увеличивают на 20% от исходного.carbonate skeleton. The assimilation of sludge by the embryo occurs at 90-195%. With an increase in the temperature of the gases for every 100 ° C, the supply of iron content, its material is increased by 20% from the original.
При температуре в кип ш;ем слое 130°С, подаче железосодержаш.его материала - металлургического мартеновского шлама, например , в количестве 0,2 кг/нм ожижающих газов, скорости ожижени 2,5 м/сек при использовании в качестве зародышей возврата фракции 1,2-4 мм получены гранулы размером 8-10 мм. При содержании извести в шламе 10%, объемна концентрапи СОа в ожижающих газах--10%, прочность полученных гранул составл ла 20 кг/окатыш.At a temperature in the boil; I have a layer of 130 ° C, the supply of iron-containing material - metallurgical open-hearth sludge, for example, in an amount of 0.2 kg / nm of fluidizing gases; 1.2-4 mm granules of size 8-10 mm were obtained. When the lime content in the sludge is 10%, the volume of CO concentration in fluidizing gases is 10%, the strength of the obtained granules was 20 kg / pellet.
Предмет изобретени Subject invention
Способ производства офлюсованных окатышей в кип ш,ем слое с использованием металлургического шлама и агломерационного возврата в качестве зародышей, включающий сушку и дегидратацию материала гор чем газом , отличающийс тем, что, с целью интенсификации процесса карбонизации и повышени прочности гранул, в слой возврата , ожижаемого газом с температурой 200- 1000°С и концентрацией двуокиси углерода 10-30 об. %, ввод т шлам .влажностью 50- 70%, содержаший 5-15 вес. % окиси кальци , причем при повышении температуры газа на каждые 100°С количество шлама увеличивают на 20% от исходного.Method for the production of fluxed pellets in a skimmer layer using metallurgical sludge and sintering as germs, including drying and dehydrating material with hot gas, characterized in gas with a temperature of 200-1000 ° C and a carbon dioxide concentration of 10-30 vol. %, a slurry of 50-70% was introduced containing 5-15% by weight. % calcium oxide, and with increasing gas temperature for every 100 ° C, the amount of sludge increases by 20% from the original.
