Abstract

Изобретение относится к металлургическому производству. Способ получения добавок, в том числе и лигатур, для производства разнообразных сплавов заключается в расплавлении и создании технологически необходимого перегрева над ликвидус основного металла и рабочих ингредиентов, перемешивании расплава, его фильтрации и кристаллизации перегретого расплава в силовых полях центрифуги при различных коэффициентах гравитации в диапазоне от 20 до 500 для получения отливок по типу твердых растворов замещения-внедрения. При этом величина технологического перегрева расплава над ликвидус в момент заливки в футерованную изложницу кристаллизатора, совместно с ее термодинамическими характеристиками, определяющими объемное равномерное охлаждение перегретого расплава со скоростью в интервале от 0,5 до 5°/с, обеспечивают время существования жидкой фазы расплава, достаточной для обеспечения двух ведущих процессов: а) обработки расплава силовым полем центрифуги при различных коэффициентах гравитации (Kg) в диапазоне от 20 до 500; при этом время обработки при заданном коэффициенте гравитации зависит от химического состава расплава, модуля температуры и скорости равномерного объемного охлаждения расплава в изложнице; определяется опытным путем и не зависит от массы обрабатываемого расплава; для большинства лигатур это время не превышает 4 мин, б) процесса кристаллизации в силовом поле центрифуги при коэффициентах гравитации в интервале от 20 до 500 до достижения остывающего расплава в изложнице кристаллизатора температуры начала процессов кристаллизации в обычных условиях. Темп движения фронта кристаллизации от внешней стенки изложницы кThe invention relates to metallurgical production. The method of obtaining additives, including ligatures, for the production of various alloys consists in melting and creating technologically necessary overheating over the liquidus of the base metal and working ingredients, stirring the melt, filtering it and crystallizing the superheated melt in the force fields of the centrifuge with different gravity coefficients ranging from 20 to 500 for producing castings according to the type of solid solutions of substitution-introduction. The value of technological overheating of the melt above the liquidus at the time of pouring the mold into the lined mold, together with its thermodynamic characteristics that determine the volumetric uniform cooling of the superheated melt at a speed in the range from 0.5 to 5 ° / s, provide a sufficient time for the melt liquid phase to provide two leading processes: a) melt processing with a centrifuge force field with different gravity factors (Kg) in the range from 20 to 500; at the same time, the processing time for a given gravity coefficient depends on the chemical composition of the melt, the module of temperature and the speed of uniform volumetric cooling of the melt in the mold; is determined empirically and does not depend on the mass of the melt being processed; for most ligatures, this time does not exceed 4 minutes, b) the crystallization process in the centrifuge force field with gravity ratios in the range from 20 to 500 until the cooling melt in the mold of the crystallizer begins to temperature of the start of crystallization processes under normal conditions. The rate of movement of the crystallization front from the outer wall of the mold to
