54 СПОСОБ ПОЛУЧЕНИЯ МЕТАЛЛИЗОВДННОГО АГЛОМЕРАТА Изобретение относитс к цветной , |металлуогии, в частности к агломера ции руд и концентратов, оно может быть применено пои агломерации заки никел . Известеч способ получени металлизованного агломеоата из закиси, включающий дробление исходного материала , смешивание его с топливом, возвратом и спекание шихты под разрежением fl . Расход твердого топлива 60%, крупность не более 1 NW. Известный способ не позвол ет достичь высокой производительности агломерационных маошн и приводит к получению агломерата с невысокой сть пенью металлизации. Цельк) изобретени вл етс повыше ;ние степени металлизации агломерата увеличение производительности .агломерационных мгшшн. Цель постигаетс тем, что исходную закись никел подвергают дроблению до крупности не более 1 мм. .сме .шивают с 5-6% топлива и возвратом, полученную шихту увлажн ют и полвевгают спеканию на колосниках под разр жением 500-800 мм вод.ст. ИЗ ЗАКИСИ НИКЕЛЯ При осуществлении способа в лабо-ч раторных услови х получают технологи-: ческие показатели процесса спекани , приведенные в таблице. Из анализа результатов экспериментальных данных видно, что процесс агломерации закиси никел идет вполне удовлетворительно с получением высоких технологических показателей. Небольшой расход топлива при хорошей металлизации и удельной производительности по агломерату обусловлен созданием наиболее благопри тных физикохимических условий дл процесса спекани и восстановлени закиси никел путем подбора оптимальной величины скорости фильтрации воздуха и соответственно СКОРОСТИ горени топлива в слое шихты при додоабливании исходной закиси никел до крупности 1-0 мм. ПРИ выбранном режиме спекани не наблюдаетс перегрева колосниковой решетки агломерационной установки и ее оплавлени . Предлагаемый способ обеспечивает прирост удельной производительности по агломерату, по сравнению с никелевым заводом Никаро (Республика54 METHOD OF OBTAINING METALLIZED SUBSTITUTE OF THE INVENTION The invention relates to non-ferrous metallography, in particular to the agglomeration of ores and concentrates, it can be applied by sintering nickel. Lime is a method of producing metallized agglomeate from nitrous oxide, which includes crushing the starting material, mixing it with fuel, returning it, and sintering the mixture under fl. Consumption of solid fuel 60%, fineness not more than 1 NW. The known method does not allow to achieve high productivity of sintering plants and results in agglomerate with a low metallization stitch. The purpose of the invention is to increase the degree of metallization of the agglomerate, an increase in the productivity of agglomeration particles. The goal is achieved by the fact that the initial nickel oxide is crushed to a particle size of not more than 1 mm. They mix 5-6% of the fuel and return, the resulting mixture is moistened and the sintering is carried out on the grate under the discharge of 500-800 mm water column. FROM NICKEL OXIDE When implementing the method in laboratory conditions, the technological parameters of the sintering process given in the table are obtained. From the analysis of the experimental data it can be seen that the process of sintering of nickel oxide is quite satisfactory with obtaining high technological performance. Low fuel consumption with good metallization and specific agglomerate productivity is due to the creation of the most favorable physicochemical conditions for the sintering process and nickel oxide reduction by selecting the optimal air filtration rate and, accordingly, the burning speed of the fuel in the charge layer when adding nickel oxide to the initial nitrous oxide to 1-0 mm When the selected sintering mode is not observed overheating of the grate of the sintering plant and its melting. The proposed method provides an increase in the specific productivity of the sinter, compared with the Nickel Nickel Plant (Republic
Куба) , на 100%, увеличение содержани общего никбл в агломерате на 10-12%,Cuba), by 100%, increasing the total nickel content in the agglomerate by 10-12%,
а также надежную работу агломашины и вспомогательного оборудовани .as well as reliable operation of the sinter machine and auxiliary equipment.
