Claims (7)

1. Способ быстрого охлаждения расплавленного керамического материала, включающий подачу струи расплавленной керамики в турбулентный поток жидкости, состоящей, по меньшей мере, из одной жидкой среды, в которой струя расплавленной керамики разбивается на поток капель, которые захватываются потоком жидкости и в виде затвердевших частиц вводятся в циклон по касательной к стенке циклона.1. A method for rapidly cooling molten ceramic material, comprising supplying a jet of molten ceramic into a turbulent fluid stream consisting of at least one liquid medium in which a jet of molten ceramic is broken into a stream of droplets that are captured by the liquid stream and are introduced in the form of solidified particles into the cyclone tangentially to the cyclone wall. 2. Способ по п.1, отличающийся тем, что керамический материал выбран из группы, состоящей из окиси магния, окиси алюминия, окиси циркония, смесей окиси алюминия с окисью циркония и окиси алюминия или циркония с добавкой небольших количеств иттрия, кремнезема, окиси магния и их смесей. 2. The method according to claim 1, characterized in that the ceramic material is selected from the group consisting of magnesium oxide, aluminum oxide, zirconium oxide, mixtures of aluminum oxide with zirconium oxide and aluminum oxide or zirconium with the addition of small amounts of yttrium, silica, magnesium oxide and mixtures thereof. 3. Способ по п.1, отличающийся тем, что турбулентный поток жидкости состоит из воздуха или воды, или смеси воздуха и воды. 3. The method according to claim 1, characterized in that the turbulent fluid flow consists of air or water, or a mixture of air and water. 4. Способ по п.1, отличающийся тем, что турбулентный поток жидкости захватывают расплавленную керамику через водный экран. 4. The method according to claim 1, characterized in that the turbulent fluid flow capture the molten ceramic through a water screen. 5. Способ по п.1, отличающийся тем, что турбулентный поток жидкости нагнетается в горловину водяной пушки. 5. The method according to claim 1, characterized in that the turbulent fluid flow is pumped into the neck of the water gun. 6. Способ по п.1, отличающийся тем, что циклон снабжен внутренними перегородками для разбивания смеси жидкости с керамикой на отдельные частицы. 6. The method according to claim 1, characterized in that the cyclone is equipped with internal partitions for breaking the mixture of liquid with ceramics into individual particles. 7. Способ по п.1, отличающийся тем, что температура циклона регулируется таким образом, что частицы на выходе из циклона сохраняют количество остаточного тепла, достаточное для исключения дополнительного источника тепла для сушки частиц. 7. The method according to claim 1, characterized in that the temperature of the cyclone is controlled in such a way that the particles leaving the cyclone retain an amount of residual heat sufficient to exclude an additional heat source for drying the particles.
