Abstract

Изобретение относится к способам изготовления легкоудаляемых высокотемпературных литейных стержней или литейных форм, а именно к водорастворимым смесям, и может быть использовано в металлургии. Техническим результатом, на достижение которого направлено изобретение, является обеспечение возможности изготовления стержней или форм, имеющих на различных участках различные физико-механические свойства. Сущность изобретения заключается в том, что способ, включает смешивание наполнителя в виде оксида алюминия со связующим в виде алюмината щелочного металла и спекание полученной смеси, и отличается тем, что спекание производят селективным нагревом отдельных участков смеси до температуры разложения алюмината щелочного металла, при этом режим нагрева отдельных участков смеси выбирают в зависимости от необходимых физико-механических свойств отдельных участков изготавливаемых стержней или форм.The invention relates to methods for producing easily removable high-temperature casting cores or casting molds, namely, water-soluble mixtures, and can be used in metallurgy. The technical result, the achievement of which the invention is directed, is the provision of the possibility of manufacturing rods or forms having different physicomechanical properties at different sites. The essence of the invention is that the method involves mixing the filler in the form of aluminum oxide with a binder in the form of an alkali metal aluminate and sintering the mixture obtained, and is characterized in that the sintering is performed by selective heating of individual sections of the mixture to the decomposition temperature of the alkali metal aluminate Heating of individual sections of the mixture is selected depending on the required physical and mechanical properties of individual sections of the produced rods or shapes.
