О) 00 Изобретение предназначено дл  футеровки различных тепловых агрегатов , например вагранок, сталераз ливочных ковшей и т.д. Известен способ изготовлени  ке рамических изделий из мелкозернистых полусухих масс путем двухстадийного прессовани  заготовок, сушки и обжига их. Недостатком такого способа  в .л етс  возникновение в опрессован ных издели х трещин, слоистой струк туры и неравномерной плотности. Описываемый способ отличаетс  от известного тем, что сначала прессуют брикеты с размерами в плос кости прессовани  на 3-8 .мм меньшими , чем однозначные размеры издели  а затем осуществл ют окончательное прессование изделий из брикетов ;82 Прессование изделий из брикетов осуществл ют при высоком (более 400 кг/см) давлении. При таком способе изготовлени  изделий резко сокращаетс  количество запрессованного воздуха, так как ori удал етс  и при прессовании брикета, и после сн ти  нагрузки. Воздух удал етс  также и в процессе последующего прессовани  из брикетов изд ёлий; при этом происходит перемещение массы брикета как в вертикальном, так. и в горизонтальном направлени х, а . ранее закупоренные воздухо-провод щие каналы открываютс  и остаток воздуха выходит. Нар ду с удалением воздуха измен етс  и структура брикета , в нем устран ютс   вные и скрытые трещины, в результате чего получаютс  издели  с равноплотной однородной структурой.O) 00 The invention is intended for the lining of various thermal units, such as cupola, steel ladles, etc. The known method of making ceramic articles from fine-grained semi-dry masses by two-stage pressing of the blanks, drying and firing them. The disadvantage of this method is the occurrence of cracks, layered structure and uneven density in the pressed products. The described method differs from the known one in that first the briquettes are pressed with dimensions in the pressing plane by 3-8 mm smaller than the unambiguous dimensions of the product and then the final pressing of the briquette products is carried out; 82 400 kg / cm) pressure. With this method of manufacturing products, the amount of compressed air is drastically reduced, since ori is removed both by pressing the briquette and after unloading. The air is also removed during the subsequent pressing process from the product briquettes; when this occurs, the movement of the mass of the briquette in the vertical as well. and horizontally, a. the previously blocked air-conducting ducts open and the rest of the air comes out. Along with the removal of air, the structure of the briquette also changes, in which clear and hidden cracks are eliminated, with the result that products with an equally dense homogeneous structure are obtained.
