Te whakaurunga o te Inoculants:Nga whakakinohe momo ka taea te whakatairanga i te graphitization, te whakaiti i te ahua o te waha ma, te whakapai ake i te morphology me te tohatoha o te graphite, te whakanui ake i te maha o te roopu eutectic, te whakamahine i te hanganga matrix.
Te whakangao matūriki ferrosilicon (whakangao motuhake mo te maka)
Ferrosiliconmatūriki ara ferrosilicon inoculant, whakamahia mo te hanga rino, rino,makangahe wero.
Nga ahuatanga o te ferrosilicon inoculant:
(1) Ko te hanganga o nga matūriki ferrosilicon he rite, he iti te wehenga;
(2) he rite te rahi o te matūriki ferrosilicon, karekau he paura pai, a he pumau te hua o te inoculation;
(3) Ko te kaha o te whakaurunga o nga matūriki ferrosilicon he kaha ake i tera o nga matūriki ferrosilicon noa, a he iti ano te ahua o te whakaputa i te slag;
(4) whakaroa i te ora o te pokepokea ai me te whakaiti i nga hapa o te mata;
(5) Whakaititia te pinhole, whakapai ake i te kounga mata o te putorino maka, me te whakapai ake i te tere o te tukunga tuatahi;
(6) whakakore i te microshrinkage me te whakapai ake i te mahi miihini o te whakarewanga.
Ko te silica-barium (konupora) whakangao
Ko te whakakorikori Silica-barium,(BA-SI)ko tehirakate paura me te paura barium ma te whakaranu kia rite ki te rahinga o te tono, katahi ka puta mai i te teitei o te wera oumu te hanga maitai ki roto i nga mea whakarewa nui. waha, te whakapai ake i te ahua me te tohatoha o te kauwhata, te whakanui i te maha o nga roopu eutectic, me te whakamahine i te hanganga matrix.
Silica-bariummahi inoculant:
1, kaha te whakanui i te graphitization matua, te whakamahine graphite, whakatairanga i te rino maka hina ki te tiki A-momo graphite, whakapai ake i te kaha, no te rino ductile taea te hanga i te kauwhata i roto i te rino ductile pai, a tawhio noa, te whakapai ake i te kōeke o spheroidization.
2. Ka taea e ia te whakaiti i te tohu supercooling o te rino whakarewa, te whakatairanga i te rerenga o te graphite, te whakaiti i te ahua o te waha ma, te whakaiti i te pakeke o te whanaungatanga, me te whakapai ake i te mahi miihini o te maka.
3. kaha anti-recession kaha, anti-recession wa ko 2 wa o75 hiona, te nui o te barium siliconwhakakinohe iti iho i te haurua o te 75 ferrosilicon inoculant, i te aukati i te paheketanga o te spheroidification.
4, he iti te tairongo matotoru o te pakitara, whakapai ake i te ahua o te waahanga, whakaitihia te ahua o te whakaheke me te waatea.
5, te hanganga matū he pūmau, he rite te granularity tukatuka, he iti te hanganga me te ine kounga.
6. He iti te ira whakarewa (iti iho i te 1300°), he ngawari ki te ngongo me te ngohe i te wa e werohia ana, he iti rawa te para.
