Изобретение относитс к металлургии , св занной с получением редких металлов методом металлотермического восстановлени .The invention relates to metallurgy associated with the production of rare metals by the method of metallothermic reduction.
Известен способ футеровани реторт безводной .окисью кальци , которую уплотн ют путем вибрации 1.A known method of lining retorts with anhydrous calcium oxide, which is compacted by vibration 1.
Известен способ футеровани углеродистыми блоками с использованием св зующего из органических материалов 2 .A known method of lining carbon blocks using a binder of organic materials 2.
Недостатками этих способов вл етс то, что они требуют использовани специальных устройств или св зующих материалов.The disadvantages of these methods are that they require the use of special devices or bonding materials.
Наиболее близким к предлагаемому вл етс способ футеровани реторт дл кальциетермического восстановлени тетрафторида циркони , включающий засыпку сло фтористого кальци между стенкой реторты и реакционной смесью 3.Closest to the present invention is a method of lining retorts for the calcium-thermal reduction of zirconium tetrafluoride, comprising filling calcium calcium fluoride between the retort wall and the reaction mixture 3.
Недостатком способа вл етс слож- ность технологического процесса в св зи с необходимостью предварительной осушки футеровки.The disadvantage of the method is the complexity of the technological process due to the need for preliminary drying of the lining.
Цель изобретени - упрощение технологии процесса.The purpose of the invention is to simplify the process technology.
Поставленна цель достигаетс тем, что засыпку сло ведут сухимThe goal is achieved by filling the bed with a dry
измельченным фтористым кальцием с размером частиц 0,03-0,50 мм или его смесью тетрафторидом циркони .crushed calcium fluoride with a particle size of 0.03-0.50 mm or its mixture with zirconium tetrafluoride.
При этом тетрафторид циркони ввод т в количестве 2-5 вес.% от общего веса.In this case, zirconium tetrafluoride is introduced in the amount of 2-5 wt.% Of the total weight.
Сущность способа заключаетс в том, что футеровку изготовл ют путем засыпки сухого измельченного The essence of the method lies in the fact that the lining is made by filling the dry ground
10 фтористого кальци с размером частиц 0,03-0,5 мм или его смеси с тетрафторидом циркони в количестве 2-5% вес. Указанный верхний предел размера частиц СаР обусловлен тем, 10 calcium fluoride with a particle size of 0.03-0.5 mm or its mixture with zirconium tetrafluoride in an amount of 2-5% by weight. The specified upper limit of the size of the particles SaR due to
15 что при большем размере частиц CaF. эффективность способа снижаетс . Нижний предел размера частиц CaF/j составл л 30-40 мк (пыль); т.е. используетс не кака -то определенна уз20 ка фракци порошка, а oi сеивают лишь частицы с -размерами, превышающими О,5 мм.15 that with a larger CaF particle size. the efficiency of the method is reduced. The lower limit of the CaF / j particle size was 30-40 microns (dust); those. no specific fraction of the powder is used, and oi sow only particles with -sizes greater than 0, 5 mm.
Предельные количества ZrF (2 и 5 вес.%), вводимые во фтористый Limit amounts of ZrF (2 and 5 wt.%) Introduced into fluoride

Футерование реторты осуществл етс следующим спосо ,бом: на дио тигел насыпаетс слой Calcium 25 is determined on the basis of achieving the required lining strength. The lining of the retort is carried out in the following way: a layer is poured onto the diode crucible.
