Description
Известны способы окомковани мелких железных руд и концентратов на агломерационных машинах ленточного типа. Одним из недостатков известных способов окомковани вл етс неполное использование топлива при обжиге.Known methods of pelletizing of small iron ores and concentrates on belt-type sintering machines. One of the disadvantages of the known hardening methods is the incomplete use of fuel during calcination.
В описываемом способе этот недостаток устранен тем, что обжиг осуществл ют при четырехзонном тепловом процессе.In the described method, this disadvantage is eliminated by the fact that the calcination is carried out at a four-zone thermal process.
Сущность описываемого способа заключаетс в том, что концентрат , содержащий 59-65% железа и увлажненный до 10-10,5i/o, измельчают до 200 меш и подают вместе с компонентами (бентонит, измельченный до +0,5 мм, каменный уголь, увлажпенный до ) на ленту агломерационной машины. Обжиг производ т при четырехзонном тепловом процессе со следующим температурным распределением: зона подсушки окатышей с температурой газов до 500°; зона подогрева и зажигани топлива с температурой 800-1100°, отделенна от зоны подсушки огнестойкой перегородкой. Температура создаетс за счет сжигани газов или жидкого топлива; зона обжига окатышей, с температурой до 1300°; зона охлаждени окатышей с температурой 300-400°.The essence of the described method is that the concentrate, containing 59-65% iron and moistened to 10-10.5 i / o, is crushed to 200 mesh and served along with the components (bentonite, crushed to + 0.5 mm, coal, moistened to) on the belt sintering machine. Calcination is performed at a four-zone thermal process with the following temperature distribution: pellet drying zone with gas temperature up to 500 °; zone of heating and ignition of fuel with a temperature of 800-1100 °, separated from the drying zone by a fire-resistant partition. Temperature is created by burning gases or liquid fuels; Pellet firing zone, with temperature up to 1300 °; cooling zone of pellets with a temperature of 300-400 °.
Предмет изобретени Subject invention
Способ обжига окатышей железных концентратов на агломерационных машинах ленточного типа, отличающийс тем, что, с целью более полного использовани топлива, обжиг осуществл ют при четырехзонном тепловом процессе со следующим температурным распределением по зонам: зона подсушки с температурой до 500°, зона подогрева и зажигани топлива с температурой 800-1100°, зона обжига с температурой до 1300° и зона охлаждени окатышей с температурой 300- -400°.The method of calcining iron concentrate pellets on belt-type sintering machines, characterized in that, in order to make fuller use of the fuel, the calcination is carried out in a four-zone heat process with the following temperature distribution over zones: a drying zone with a temperature of up to 500 °, a zone of heating and ignition of fuel with a temperature of 800-1100 °, a burning zone with a temperature of up to 1300 ° and a cooling zone of pellets with a temperature of 300-400 °.
