Abstract
1. Способ получения абразивного материала путем плавления смеси оксидов алюминия и циркония с получением расплава с дефицитом кислорода относительно стехиометрического состава, разливки расплава в рабочее пространство между плитами кристаллизатора, соединенными стяжками, сжимающими пакет плит за счет сил гравитации, охлаждения расплава и его кристаллизацию вместе с плитами, снятия гравитационного сжатия, извлечения полученного материала, отличающийся тем, что совместное охлаждение закристаллизовавшегося расплава и плит кристаллизатора производят до момента, когда температура пластин, полученных из расплава, и температура поверхности плит выравнивается, извлеченный из кристаллизатора циркониевый электрокорунд охлаждают на воздухе отдельно от плит кристаллизатора. ! 2. Способ получения абразивного материала по п.1, отличающийся тем, что охлаждение расплава вместе с плитами кристаллизатора производят до температуры 700 - 600°С. ! 3. Способ получения абразивного материала по п.1, отличающийся тем, что охлаждение расплава вместе с плитами кристаллизатора производят в течение 10 ч 20 мин после разливки. ! 4. Кристаллизатор, содержащий секции плит, между которыми образовано рабочее щелевое пространство для размещения расплава, плиты в секции гравитационно сжаты подвешенными на опорах стяжками, отличающийся тем, что в качестве стяжки использована цепь. ! 5. Кристаллизатор по п.4, отличающийся тем, что верхние части плит выполнены в виде одностороннего клина. ! 6. Кристаллизатор по п.5, отличающийся тем, что угол при вершине клина составляет 30°. 1. A method of producing abrasive material by melting a mixture of aluminum and zirconium oxides to obtain an oxygen-deficient melt relative to the stoichiometric composition, pouring the melt into the working space between the mold plates connected by couplers, compressing the plate pack due to gravitational forces, melt cooling and its crystallization together with plates, removing gravitational compression, extracting the obtained material, characterized in that the joint cooling of the crystallized melt and crystallization plates produce the torus until the wafer temperature from the melt, and the temperature of the surface plates aligned extracted from crystalliser zirconium corundum cooled air separately from the mold plates. ! 2. The method of producing abrasive material according to claim 1, characterized in that the melt is cooled together with the mold plates to a temperature of 700 - 600 ° C. ! 3. The method of producing abrasive material according to claim 1, characterized in that the cooling of the melt together with the plates of the mold is carried out for 10 hours 20 minutes after casting. ! 4. A mold containing sections of plates between which a working gap is formed to accommodate the melt, plates in the section are gravitationally compressed by ties suspended on supports, characterized in that a chain is used as a coupler. ! 5. The mold according to claim 4, characterized in that the upper parts of the plates are made in the form of a one-sided wedge. ! 6. The mold according to claim 5, characterized in that the angle at the top of the wedge is 30 °.
