Изобретение относитс к производству огнеупорных керамических изделий и может быть использовано в производстве форстеритовых огнеупоров.The invention relates to the production of refractory ceramic products and can be used in the production of forsterite refractories.
Цель изобретени - повышение проч ности изделий.The purpose of the invention is to increase the strength of the products.
Используемый в предлагаемом составе прокаленный хризотиловьй асбест,Used in the proposed composition calcined chrysotile asbestos,
облада высокой реакционной способностью , легко вступает в реакцию с оксидом магни , а фтористый магний способствует процессу спекани продукта , снижа при этом температуру обжига до 1450°С (у известного состава 1500-1550°С), и увеличению прочности издели .It has a high reactivity, easily reacts with magnesium oxide, and magnesium fluoride contributes to the process of sintering the product, reducing the burning temperature to 1450 ° C (with a known composition of 1500-1550 ° C), and increase the strength of the product.
Шихту готов т следующим образом. Хризотиловый асбест предваритель .но прокаливают при 600-750°С в течение 4ч, оксид магни измельчают в шаровой мельнице до размера частиц 20 - 60 мкм совместно с фторидом магни ..The mixture is prepared as follows. Chrysotile asbestos precursor is calcined at 600–750 ° C for 4 h, magnesium oxide is ground in a ball mill to a particle size of 20–60 μm together with magnesium fluoride ..
Затем исходные компоненты (хризотиловый асбест, оксид магни и фторид магни ) смешивают в пред188145 ,2Then the starting components (chrysotile asbestos, magnesium oxide and magnesium fluoride) are mixed in pre 188145, 2
лагаемых соотношени х и готов т водный шликер. Полученнную пластичную массу разливают в формы и сушат при 60 G в течение 2,5 ч и при lag ratios and prepare a water slip. The resulting plastic mass is poured into molds and dried at 60 G for 2.5 hours and at
5 в течение 5 ч. Обжиг производ т при 1450 С. Составы шихт приведены в табл. 1. Свойства материалов, полученньпс при различной температуре, приведены в табл. 2. 5 for 5 hours. Firing is performed at 1450 C. The composition of the mixture is given in Table. 1. Properties of materials obtained at different temperatures are given in table. 2
