Te Whanaketanga Hangarau me te Mahi Whakamahinga o ngā Mīhini Whakaranu me te Whakakotahi Ferrite Ngāwari
Ko ngā ferrite ngohengohe (pērā i te manganese-konutea me te nikara-konutea) he rauemi matua mō ngā wāhanga hiko, ā, he tino whakawhirinaki tō rātou mahi ki te ōritetanga o te whakaranu rauemi mata me te whakapūkara. Hei taputapu matua i roto i te tukanga hanga, kua tino whakapai ake ngā mīhini whakaranu me te whakapūkara i te urunga aukume, te whakahaere ngaronga, me te pumau pāmahana o ngā rauemi aukume ngohengohe mā te auahatanga hangarau i ngā tau tata nei.
Taputapu Mīhini Whakakotahi Ferrite Ngāwari
Ngā Whakaritenga Whakaranu Teitei: Me whakaranu ōrite ngā wāhanga matua (te waikura rino, te konupūmā, me te konutea) me ētahi atu tāpiringa iti (pērā i te SnO₂ me te Co₃O₄) mō ngā ferrite ngohengohe. Ki te kore e pērā, ka kore e ōrite te rahi o te kōpaka i muri i te whakahinuhinu, ā, ka piki ake te pikinga o te uruhanga aukume.
Ka pā te tukanga whakapūkara ki te mahi whakamutunga: Ka pā tika te matotoru, te āhua, me te rahi o ngā matūriki ki te matotoru i hangaia me te whakahekenga o te sintering. He ngāwari te puehu ki ngā tikanga kuru ā-ringa tuku iho, engari ka taea e te whakapūkara extrusion te kino i te paninga tāpiri.
Te Mātāpono o te Mīhini Whakaranu me te Whakaranu Tino-kaha mō ngā Rauemi Aukume
Mātāpono: Mā te whakamahi i tētahi rango piko me ngā impeller toru-ahu tere-teitei, ka tutuki i tēnei mīhini te whakaranu me te whakapūkara whakauru mā te mahi tahi o te kaha poipoi me te waku.
Ngā painga o te whakamahi i te granulator mō te whakarite rauemi aukume:
Te pai ake o te ōritetanga o te ranunga: Te rere o ngā rauemi maha-ahu, te hapa marara tāpiri <3%, me te whakakore i te pupū.
Te pai o te hanga kirikiri: Ka whakaitihia te wā tukatuka kotahi-haerenga mā te 40%, ā, ka eke te porowhita o te kirikiri ki te 90%, ka whakapai ake i te kiato whakakīkī i muri mai.
Ngā Whakamahinga: Te whakapūkara i ngā rauemi kua whakapūkarahia i mua i te ferrite me te whakaranu i ngā here mō ngā aukume tūturu whenua onge (pērā i te NdFeB).
