Description

При производстве глинозема по так называемому мокрому способу, в котором питание печи спекани  ведетс  не сухой шихтой, а шламмом, по консистенции близким к шламму при производстве цемента по мокрому способу, возникают трудности с ведением процесса в холодном конце печи, т. е. со стороны питани  печи сырым материалом .In the production of alumina according to the so-called wet method, in which the sintering furnace is fed not by the dry mixture, but by sludge, which is similar in consistency to sludge in the production of cement by the wet method, difficulties arise in conducting the process in the cold end of the furnace, i.e. feeding the furnace with raw material.

В холодном конце печи образуютс  настыли и кольца столь крепкие, что дл  сбивани  их требуетс  остановка печи. Такое отличие процесса в холодном конце печи, по сравнению с мокрым способом производства цемента, можно объ снить наличием в составе шихты соды, котора   вл етс  хорошим св зующим, что и определ ет большую плотность настылей. Применение способа питани  печи распыленным шламмом , аналогичного примен емому в цементной промышленности, несколько снизило образование настылей, но отнюдь не устранило их полностью. При попытке вести печь на производительности , сколько нибудь превышающей низкий уровень на 1 куб. м печного пространства, лет ща  от форсунки пыль сырого материала не успеваетIn the cold end of the furnace nastily are formed and the rings are so strong that stopping the furnace is required to bring them down. Such a difference in the process in the cold end of the kiln, as compared to the wet method of cement production, can be explained by the presence of soda in the batch, which is a good binder, which determines the high density of walling. The use of the method of feeding the furnace with atomized sludge, similar to that used in the cement industry, somewhat reduced the formation of wall accretions, but did not eliminate them completely. When you try to keep the oven on performance, as anything above the low level of 1 cu. m of furnace space, flying from the nozzle dust raw material does not have time

Попавший на стенки печи шламм склонен приставать к стенкам и, несмотр  на наличие в холодном конце отбойных механизмов (болванок, св занных в цепочку), рост настылей в холодном конце печи продолжает увеличиватьс .Slurry on the walls of the furnace tends to stick to the walls and, despite the presence of baffling mechanisms (chained blanks) in the cold end, the growth of wall buildup in the cold end of the furnace continues to increase.

Подобна  картина наблюдаетс  на опытной печи, а естественно, что на заводской печи больших размеров могут получитьс  крупные осложнени  даже при нормальных услови х работы.A similar picture is observed in a pilot furnace, and it is natural that large-sized factory furnaces can cause major complications even under normal operating conditions.

При вс ком же отступлении от нормальных условий, например, при смещении в печи зоны спекани , что может произойти в зависимости от питани  печи горючим или сырым материалом , зона первоначальной и дальнейшей подсушки сместитс , что вызовет неблагопри тные последстви  в смысле кольцеобразовани .If there is any deviation from normal conditions, for example, when a sintering zone is displaced in the furnace, which can occur depending on the furnace supply with combustible or raw material, the initial and further drying zone will shift, which will cause unfavorable consequences in terms of ring formation.
