Description
нажимными винтами 13, помещенными в герметические колпачки 14.push screws 13, placed in hermetic caps 14.
Предлагаемую шахтную печь испытывают на процессе металлотермического восстановлени тугоплавких металлов.The proposed shaft furnace is tested on the process of metal-thermal reduction of refractory metals.
Шахта зафутерована изнутри трапецеидальными блоками из графита, которые поджимаютс друг к другу нажимными винтами с усилием в стыках, равным 1 кг/см, затем установку собирают но фиг. 1 и через патрубок 8 заполн ют аргоном . Через устройство 3 загружают шихту, заналом 4 инициируют реакцию металлотермнческого восстановлени . После отсто через летку 6 слнвают шлак, отсоедин ют поддон и направл ют его на разборку плавки . Качество металла по примес м на уровне требований, извлечение составл ет 95%.The shaft is lined from the inside with graphite trapezoidal blocks, which are pressed against each other by pressure screws with a force in the joints of 1 kg / cm, then the installation is assembled, but FIG. 1 and through pipe 8 is filled with argon. A charge is loaded through the device 3, and initiation of the metallothermic reduction reaction is carried out by means of the zander 4. After settling through the letting station 6, slag is removed, the pallet is disconnected and sent to disassemble the heat. The quality of the metal is by impurities at the level of requirements, the extraction is 95%.
Футеровка шахты выдерживает 52 плавки .The lining of the mine withstands 52 melts.
Использование шахтной печи обеспечивает увеличение выхода ниоби на операции восстановлени до 95% за счет повышени герметичности, что снижает потери металла за счет уменьшени пылеуноса в процессе загрузкн шихты и при восстановлении .The use of a shaft furnace provides an increase in the output of niobium in a reduction operation up to 95% due to an increase in leaktightness, which reduces metal losses due to a decrease in pulverization during the charging process and during recovery.
Изменение конфигурации футеровки шахты нечи, выполненной расширением книзу и выступающей леткой внутрь шахты печи,Changing the configuration of the lining of the mine nech, performed by extending downwards and protruding the entrance into the shaft of the furnace,
позвол ет снизить количество гарннссажа из металла, кристаллизующегос на внутренних стенках шахты печи, что повышает выход металла в слиток. allows to reduce the amount of garnssage from metal crystallizing on the inner walls of the furnace shaft, which increases the yield of metal into the ingot.
