Description
Изобретение относитс к порошковой металлургии, в частности к установкам дл получени металлических порошков распылением расплавов.The invention relates to powder metallurgy, in particular, to installations for the production of metal powders by spraying melts.
Известна установка дл получени металлических порошков, включающа камеру распылени , плавильную печь, установленную над камерой, форсунку и сборник порошка 1.A known apparatus for producing metal powders, comprising a spray chamber, a smelting furnace installed above the chamber, a nozzle and a collection of powder 1.
Недостатком данной установки вл етс ее низка производительность обусловле.нна периодичностью работы печи.The disadvantage of this installation is its low productivity due to the frequency of operation of the furnace.
Наиболее близким-к предлагаемому по технической сущности и достигаемому эффекту вл етс установка дл получени металлических порошков, .включающа камеру распылени форсунки , промежуточное устройство и бункер дл приема порошка. При этом установка снабжена также плавильной печью, а промежуточное устройство выполнено съемным и снабжено огнеупорной футеровкой 2.The closest to the proposed technical essence and the achieved effect is the installation for the production of metal powders, which includes a nozzle spray chamber, an intermediate device and a hopper for receiving powder. The installation is also equipped with a melting furnace, and the intermediate device is made removable and equipped with a refractory lining 2.
Недостатками данной установки вл ютс низкий выход годного порошка обусловленный значительными потер ми металла, а также низкое качество распыленного порошка.The disadvantages of this setup are the low yield of the powder due to significant metal loss, as well as the poor quality of the sprayed powder.
Цель изобретени - снижение потерь металла и повышение качес1:ва распыленного порошка.The purpose of the invention is to reduce metal losses and increase the quality of the sprayed powder.
Дл достижени указанной цели установка снабжена плазматронами, установленными в верхней части промежуточного устройства.To achieve this goal, the installation is equipped with plasmatrons installed in the upper part of the intermediate device.
На чертеже схематически показан The drawing shows schematically
0 предпочтительный вариант выполнени предложенной установки..0 preferred embodiment of the proposed installation ..
Установка состоит из индукционной печи 1, промежуточного устройства 2, подового сливного стакана 3, камеры 5 4 распылени , форсунки 5 и бункера 6 дл приема порошка. Дл поддержани посто нной температуры металлического расплава в промежуточном устройстве , последнее оснащено футерован0 ным сводом 7, в котором вмонтированы три плазматрона 8, работающих на переменном токе.The installation consists of an induction furnace 1, an intermediate device 2, a bottom drain cup 3, a spray chamber 5 4, a nozzle 5, and a hopper 6 for receiving powder. In order to maintain a constant temperature of the metal melt in the intermediate device, the latter is equipped with a lined arch 7, in which three plasmatrons 8 are mounted, operating on alternating current.
Дл создани контролируемой атмос5 внутри промежуточного устройства заливочна -чаша 9 снабжена футерованной крышкой 10 с редукционным клапаном 11. Кроме этого, промежуточное устройство оборудовано термопаG рой 12 и соответствующей контрольноTo create a controlled atmosphere5 inside the intermediate device, the casting cup 9 is equipped with a lined lid 10 with a reducing valve 11. In addition, the intermediate device is equipped with a thermocoura 12 and a corresponding control valve.
