1. Te hanga o te ferrosilicon
Ko te Ferrosilicon he koranu rino he rino me te hiraka.Ko te Ferrosilicon he koranu rino-silicon i hangaia mai i te coke, i nga kongakonga rino, i te quartz (te silica ranei) hei rauemi mata, ka whakarewahia ki roto i te oumu hiko.I te mea he ngawari te whakakotahi o te hiraka me te hāora ki te hanga silica, ka whakamahia te ferrosilicon hei deoxidizer i roto i te hanga maitai.I te wa ano, mai i te mea ka tukuna e te SiO2 te nui o te wera i te wa e hangaia ana, he pai ano hoki te whakanui ake i te wera o te rino whakarewa i te wa e whakahekehia ana.I te wa ano, ka taea hoki te whakamahi i te ferrosilicon hei taapiri huānga whakakotahi me te whakamahia whanui i roto i te rino hanganga-iti, te maitai o te puna, te rino e mau ana, te rino wera-wera me te rino hiko hiko.Ka whakamahia te Ferrosilicon hei kaihoko whakaheke i roto i te hanga ferroalloy me te umanga matū.
2. Te tono o te ferrosilicon
Ferrosilicon te whakamahia whānuitia i roto i te ahumahi maitai, te makanga ahumahi me etahi atu mahi ahumahi.
Ko te Ferrosilicon he deoxidizer nui i roto i te umanga hanga maitai.I roto i te rino rama, ka whakamahia te ferrosilicon mo te whakamaaramatanga o te rerenga me te whakamaarama whakamaarama.Ka whakamahia hoki te rino pereki hei kaihoko whakarewa mo te hanga maitai.Ko te taapiri i te nui o te silicon ki te rino ka taea te whakapai ake i te kaha, te pakeke me te elasticity o te maitai, te whakapai ake i te uruhanga o te maitai, me te whakaiti i te ngaro o te hysteresis o te tira whakawhiti.Ko te maitai whanui kei roto 0.15% -0.35% silicon, kei roto i te maitai hanganga 0.40% -1.75% silicon, kei roto i te maitai taputapu te 0.30% -1.80% te silicon, kei roto i te maitai o te puna 0.40% -2.80% te silicon, te kowiri tira waikawa-atete. kei roto 3.40% -4.00% silicon, me te maitai wera-ātete kei roto 1.00% ~ 3.00% silicon.Ko te maitai Silicon kei roto 2% ki te 3% silicon teitei ake ranei.
Ko te ferroalloy silicon teitei, ko te koranu siliceous ranei e whakamahia ana i roto i te umanga ferroalloy hei whakaiti i nga kaihoko mo te hanga o nga ferroalloys waro iti.Ko te taapiri i te ferrosilicon ki te maka rino ka taea te whakamahi hei inoke o te rino maka nodular, ka taea te aukati i te hanganga o te carbide, te whakatairanga i te rerenga me te nodulation o te kauwhata, me te whakapai ake i te mahi o te rino.
I tua atu, ka taea te whakamahi i te paura o te ferrosilicon hei waahi irihia i roto i te ahumahi tukatuka kohuke, me te whakakikorua mo nga rakau pupuhi i roto i te ahumahi whakangao.Ka taea te whakamahi i te hiako rino rino teitei ki te whakarite i te semiconductor silicon parakore i roto i te ahumahi hiko, ka taea te whakamahi ki te hanga silicone i roto i te ahumahi matū.
I roto i te ahumahi hanga maitai, mo te 3 ~ 5kG 75% o te ferrosilicon e pau ana mo ia tana o te maitai i mahia.
