Description
Изобретение относитс к технологии керамики и огнеупоров, а именно к технологии производства керамических изделий с плотноспекшимс черепком.The invention relates to the technology of ceramics and refractories, in particular to the technology for the production of ceramic products with a dense shard.
Цель изобретени - снижение температуры обжига изделий.The purpose of the invention is to reduce the firing temperature of products.
Шлам газоочистки производства марганцевого агломерата вл етс отходом ферросплавного производства и характеризуетс следующим химическим составом , %: SiOz 16,7-22,2; МпО + .Мп02 30-45,8} СаО 8,3-12,5; MgO 3,1-6,5; A140S 0,5-5,1; 0,8-2,4; Р 0,15- 1,3; KftO 2,5-3,1; NaaO 2,5-3,2; С 2-3,5; S 0,7-0,85.The gas cleaning sludge from the production of manganese sinter is a waste of ferroalloy production and is characterized by the following chemical composition,%: SiOz 16.7-22.2; MpO + .Mn02 30-45,8} CaO 8.3-12.5; MgO 3.1-6.5; A140S 0.5-5.1; 0.8-2.4; P 0.15-1.3; KftO 2.5-3.1; NaaO 2.5-3.2; C 2-3,5; S 0.7-0.85.
Гранитные отсевы камнедроблени представлены кварцем (50-60%), микро- клином (6-19%), плагиоклазом (19 - 34%) и амфиболом (5-7%).Granite stone crushing screenings are represented by quartz (50–60%), microcline (6–19%), plagioclase (19–34%), and amphibole (5–7%).
Глину и шлам газоочистки производства марганцевого агломерата распускают в пропеллерной мешалке. Гранитные отсевы камнедроблени мелют в шаровых мельницах до остатка 2% на сите 0056. Керамический нликер получают объемным смешиванием данных суспензий. Шликер подвергают интенсивной сушке в башенно-м распылительном сушиле и получают пресс-порошок влажностью 6-7%. Образцы изделий получают полусухим прессованием при удельном давлении 24 МПа, сушат до остаточной влажности 0,5% и обжигают в туннельной печи в течение 36 ч при максимальной температуре обжига 960-980°С с выдержкой 1 .Clay and sludge gas cleaning manganese sinter production dissolve in a propeller mixer. Granite stone crushing screenings are ground in ball mills to a residual of 2% on a 0056 sieve. Ceramic clinker is obtained by volumetric mixing of these suspensions. The slip is subjected to intensive drying in a turret m spray dryer and receive press powder humidity 6-7%. Samples of products are obtained by semi-dry pressing at a specific pressure of 24 MPa, dried to a residual moisture content of 0.5%, and calcined in a tunnel kiln for 36 hours at a maximum calcining temperature of 960–980 ° C with a holding time of 1.
В таблице представлены составы ке- рамических масс и свойства изделий из них.The table shows the composition of ceramic masses and the properties of products made from them.
