Description
Существующие способы изготовлени огнеупорных полых изделий (тиглей и других сосудов) не дают возможности примен ть малопластичные или непластичные материалы. Дл изготовлени же сосудов с огнеупорностью , превышающей 1600-2000°, приходитс обычно примен ть непластичные материалы, например, окись алюмини , окись циркони , окись берилли , карбиды и т. д.Existing methods for making refractory hollow articles (crucibles and other vessels) do not allow the use of low-ductile or non-ductile materials. For the manufacture of vessels with refractoriness exceeding 1600-2000 °, it is usually necessary to use non-plastic materials such as alumina, zirconia, beryllium oxide, carbides, etc.
Предлагаемый способ имеет целью избежать трудностей, сопутствующих формованию высокоогнеупорных сосудов .The proposed method aims to avoid the difficulties associated with molding high-refractory vessels.
На чертеже изображен вертикальный разрез сосуда, формуемого по предлагаемому способу.The drawing shows a vertical section of a vessel molded by the proposed method.
На болванку /, сделанную из дерева или вообще из какого-нибудь твердого вещества, со сквозным отверстием 6, наматываетс слой 2, состо щий из целлюлоидной пленки или из любого тонкого водонепроницаемого материала, не размокающего в воде. На слой 2 наматываетс слой 3 гигроскопической ткани. Затем наноситс слой 4 формуемого огнеупорного материала, причем масса его состоит из смеси двух или трех фракций измельченного огнеупорного материала (например, окиси алюмини или окиси циркони , или окиси берилли , или карбидов и т. д.), смоченного водопроводной или дестйллированной водой.A layer 2 made of wood or even of some solid substance with a through hole 6 is wound with a layer 2 consisting of a celluloid film or of any thin waterproof material that does not soak in water. A layer 3 of absorbent tissue is wound on layer 2. Then a layer 4 of molded refractory material is applied, and its mass consists of a mixture of two or three fractions of crushed refractory material (for example, alumina or zirconium oxide, or beryllium oxide, or carbides, etc.) moistened with tap water or distilled water.
Снаружи слой 4 массы завертываетс в слой 5 гигроскопической ткани.Outside, the mass layer 4 is wrapped in a layer 5 of absorbent tissue.
После удалени избытка воды из сло 4 через гигроскопические слои 3 и 5 производитс выемка болванки 7 и освобождение отформованного тигл от слоев-водонепроницаемого 2 и гигроскопических 5 и 5. Затем тигель обычным путем обжигаетс .After removing excess water from layer 4 through hygroscopic layers 3 and 5, blanks 7 are dredged and the molded crucible is released from the layers of waterproof 2 and hygroscopic 5 and 5. Then the crucible is burned in the usual way.
Предмет изобретени .The subject matter of the invention.
Способ формовки высокоогнеупорных тиглей и других сосудов из непластичных или малопластичных материалов , отличающийс тем, что болванку обертывают тонким слоем водонепроницаемого материала и затем слоем гигроскопической ткани, после чего нанос т смоченный водой формуемый материал, затем его обертывают гигроскопической тканью и после впитывани воды гигроскопическими сло ми извлекают болванку, а отформованное изделие освобождают от гигроскопических слоев и водонепроницаемого материала.A method of forming high-refractory crucibles and other vessels from non-plastic or low-plastic materials, characterized in that the blank is wrapped with a thin layer of waterproof material and then with a layer of absorbent fabric, after which the moldable material is moistened with water, then wrapped with absorbent fabric and after absorbing water with hygroscopic layers remove the blank, and the molded product is free from hygroscopic layers and waterproof material.
