Description

Показатели агломерации шихты в сравнении с шихтой, снекаемой на аглофабриках , приведены в таблице.Indicators of agglomeration of the charge in comparison with the charge, snekayem on sinter plants, are given in the table.

Снижение нроизводительноети аглоустановки происходит за счет большей влажности предложенной шихты и меньшего объемного веса. Качество агломерата заметно лучше цри спекании предложенной шихты.The reduction of the productive capacity of the sintering plant is due to the greater moisture content of the proposed charge and lower volumetric weight. The quality of the agglomerate is much better than the sintering of the proposed mixture.

Прн получении окатышей из предложенной шихты и их обжиге в окислительной атмосфере получены следуюш,ие результаты:The production of pellets from the proposed mixture and their roasting in an oxidizing atmosphere yielded the following results:
