ʻO ka hoʻohana ʻana o Ferrosilicon a me nā kaʻina hana

He kiʻekiʻe loa ka pilina kemika ma waena o ke silika a me ka oxygen, no laila hoʻohana ʻia ka ferrosilicon ma ke ʻano he deoxidizer (deoxidation precipitation a me diffusion deoxidation) i ka ʻoihana hana kila. Ma waho aʻe o ke kila paila a me ke kila semi-pepehi, ʻaʻole pono ka liʻiliʻi o ka silicon ma ke kila ma lalo o 0.10%. ʻAʻole hana ʻo Silicon i ka carbide i ke kila, akā aia i loko o ka hopena paʻa i ka ferrite a me ka austenite. He hopena ikaika ka Silicon i ka hoʻomaikaʻi ʻana i ka ikaika o ka hopena paʻa i ke kila a me ke anuanu e hana ana i ka deformation hardening rate, akā e hōʻemi i ka paʻakikī a me ka plasticity o ke kila; Loaʻa iā ia ka hopena maʻalahi i ka paʻakikī o ke kila, akā hiki ke hoʻomaikaʻi i ka paʻa ʻana o ka tempering a me ke kūpaʻa oxidation o ke kila, no laila ua hoʻohana ʻia ka hao silika ma ke ʻano he mea hoʻohui i ka ʻoihana hana kila. Loaʻa iā Silicon nā hiʻohiʻona o ke kūpaʻa kikoʻī nui, ka conductivity thermal maikaʻi ʻole a me ka conductivity magnetic ikaika. Loaʻa i ke kila kekahi nui o ka silikoni, hiki ke hoʻomaikaʻi i ka permeability magnetic o ke kila, hoʻemi i ka nalowale o ka hysteresis, a hōʻemi i ka nalowale o kēia manawa. ʻO ke kila uila he 2% a 3% Si, akā pono ka haʻahaʻa o ka titanium a me ka boron. ʻO ka hoʻohui ʻana i ke silika i ka hao hiki ke pale i ka hoʻokumu ʻana o nā carbide a hoʻoikaika i ka ua a me ka spheroidization o ka graphite. ʻO ka hao silikon-magnesia kahi mea hoʻohana spheroidizing maʻamau. Hoʻohana ʻia ka Ferrosilicon me ka barium, zirconium, strontium, bismuth, manganese, rare earths, etc. ma ke ʻano he inoculant i ka hana hao. ʻO ka ferrosilicon kiʻekiʻe he mea hoʻohaʻahaʻa i hoʻohana ʻia i ka ʻoihana ferroalloy e hana i nā ferroalloys haʻahaʻa. Hoʻohana ʻia ka pauka Ferrosilicon e pili ana i ka 15% silicon (particle size <0.2mm) ma ke ʻano he mea kaupaona i ka hoʻoili ʻana i ka mineral media kaumaha.

ʻO ka mea hana ferrosilicon he umu uila hoʻohaʻahaʻa arc i lalo. Hoʻomalu ʻia ka ʻike silika o ka ferrosilicon e ka nui o nā mea hao. Ma waho aʻe o ka hoʻohana ʻana i ka silica maʻemaʻe a me nā mea hoʻohaʻahaʻa e hana i ka ferrosilicon maʻemaʻe kiʻekiʻe, pono ka hoʻomaʻemaʻe ʻana ma waho o ka umu e hōʻemi i nā haumia e like me ka aluminika, ka calcium, a me ke kalapona i loko o ka alloy. Hōʻike ʻia ke kahe kaʻina hana ferrosilicon ma ka Figure 4. Ferrosilicon i loaʻa iā Si≤ 65% hiki ke hoʻoheheʻe ʻia i loko o kahi umu uila i pani ʻia. Hoʻoheheʻe ʻia ʻo Ferrosilicon me Si ≥ 70% i loko o kahi umu uila hāmama a i ʻole ka umu uila semi-pani.
