Description
Изобретение относитс к области подготовки сьфь и может быть использовано при производстве офлюсованного марганцевого агломерата дл выплавки углеродистого ферромарганца в доменных или электрических печах.The invention relates to the field of preparation of SF and can be used in the production of fluxed manganese sinter for smelting carbon ferromanganese in blast furnaces or electric furnaces.
Цель изобретени - повышение прочности , паровлагостойкости, темпера- туры плавлени агломерата и производительности агломерационных установок .The purpose of the invention is to increase the strength, vapor resistance, melting temperature of the agglomerate and the performance of sinter plants.
Способ осуществл етс следующим образом.The method is carried out as follows.
Дл спекани агломерата использовали марганцевый концентрат, мас,% Мп41,7; ,9; СаО 4,6; MgO 1,2; Fe., 0,8 фракции 10 мм, влажностью 8-12й, коксовую мелочь -Змм, известн к-ракушечник , мас,%: SiO. 1,3; СаО 49,6; MgO 1,5; .UO фракции 3-0 мм и железорудньй концентрат Мп 0,1; SiOa8,1; СаО 1,2; MgO 0,7; Ffо5ц 57,0For sintering the agglomerate, manganese concentrate was used, wt.% Mn41.7; ,9; CaO 4.6; MgO 1,2; Fe., 0.8 fractions 10 mm, humidity 8-12th, coke breeze - 3 mm, limestone-shell rock, wt.%: SiO. 1.3; CaO 49.6; MgO 1.5; .UO fraction of 3-0 mm and iron ore concentrate Mp 0.1; SiOa8.1; CaO 1,2; MgO 0.7; Ffoc 57.0
Спекание агломерата проводили на установке с площадью спекани t,0 м . Высота сло 350 мм, начальное разрежение 800 мм«.водост,, продолжительность зажигани 1,5-2 мин при Выход годного из спека определ ли по содержанию фракции +10 мм после разового сбрасьгоани пирога агломерата с высоты 2 ммоSintering of the agglomerate was performed on the installation with the area of sintering t, 0 m. The height of the layer is 350 mm, the initial vacuum is 800 mm. Water, the duration of ignition is 1.5-2 min. The yield from the cake is determined by the content of the fraction + 10 mm after a single slug of the agglomerate cake from a height of 2 mm.
Механическую прочность агломерата, определ ли согласно ГОСТу, а паро- влагостойкость агломерата - по содержанию фракции +5 мм после обработки паром в течение 90 мин пробы агломерата фракции 10-80 мм весом 1 кг, The mechanical strength of the agglomerate was determined according to GOST, and the moisture and moisture resistance of the agglomerate was determined according to the content of the fraction +5 mm after steaming for 90 min of the sample of the agglomerate fraction 10-80 mm weighing 1 kg,

Введение в состав шихты железорудного концентрата позвол ет интенсифицировать процессы спекани офлюсованного агломерата за счет ускорени растворени оксидов кальци и магни , способствует их усвоению марганецсодержащим расплавом. Наличие железа приводит к образованию легкоплавких эвтектик ферритов кальци , магни , кобсита. При этом происходит стабилизаци фаз, образующихс в системе Mn-Fe-0-Ca-Mg, и тем самым уменьшаютс фазовые превращени , привод щие к разрушению офлюсованного агломерата.The introduction of iron ore concentrate into the mixture makes it possible to intensify the processes of sintering fluxed agglomerate by accelerating the dissolution of calcium and magnesium oxides, which contributes to their assimilation by manganese-containing melt. The presence of iron leads to the formation of low-melting eutectics of calcium ferrites, magnesium, cobsite. In this case, the phases formed in the Mn-Fe-0-Ca-Mg system are stabilized, and thus the phase transformations are reduced, leading to the destruction of the fluted agglomerate.
Изобретение позвол ет увеличить выход годного на 27%, механическую прочность на 41%, паровлагостойкость на 56%, температуру плавлени на 80 СоThe invention allows to increase the yield by 27%, mechanical strength by 41%, steam and moisture resistance by 56%, melting point by 80 Co.
