Abstract
Сущность изобретени заключаетс в том. что издели из металлических порошков получают с использованием в качестве исходного основного металлсодержащего компонента горнорудного концентрата Горнорудный концентрат 22. порошки восстановител 23 и легирующих добавок 24 измельчают в агрегате 1. дозируют в агрегат 2 и смешивают в агрегате 3 Полученную шихту 25 устройством 5 постепенно подают в емкость 4 С помощью воздействи на шихту и ферромагнитный сердечник 19 высокочастотными магнитными пол ми индуктора 7 производ т послойный нагрев шихты При этом шихта подвергаетс ультразвуковой вибрации Нагрев провод т до температуры 0.4 - 08 температуры плавлени основного компонента шихты Подаваемый в емкость 4 восстановительный газ 8 пронизывает противотоком весь восстанавливаемый объем шихты. Выход щий из емкости 4 восстановленный порошок в дальнейшем обра- батырзют либо путем экструзии с помощью фильеры 11 и оправки 12, индукционного спекани в индукторе 13 Другой вариант обработки заключаетс в формообразовании путем прокатки в охлаждае- к ь:х гппхох прокатсого стана. Обработка предусматривает также охлаждение в восстановительной ипи инертной атмосфере дл получени -собственно отожженного металлического порошка 2 с и 7 зпф-лы. 3 ипSUMMARY OF THE INVENTION that products from metal powders are obtained using the mining concentrate 22 as the initial main metal-containing component of the mining concentrate. The reducing agent 23 and dopant 24 powders are crushed in the aggregate 1. Dosed in the aggregate 2 and mixed in the aggregate 3. The resulting mixture 25 is gradually fed into the container by the device 5 4 By acting on the charge and the ferromagnetic core 19 by the high-frequency magnetic fields of the inductor 7, the charge is layer-by-layer heated. ukovoy vibration heating is carried out to a temperature of 0.4 - 08 melt temperature of the major component in the batch feed tank 4 8 reducing gas permeates countercurrent entire volume of the reducible mixture. The recovered powder leaving the container 4 is further processed either by extrusion using a die 11 and a mandrel 12, induction sintering in the inductor 13 Another processing variant consists in shaping by rolling to a chilled rolling mill. The treatment also includes cooling in a reducing or inert atmosphere to obtain 2 s and 7 cpf-α-annealed metal powder. 3 ip
