ʻO kahi alloy binary i haku ʻia me ke silika a me ka calcium no ka ʻāpana o nā ferroalloys.ʻO kāna mau mea nui he silikoni a me ka calcium, a loaʻa pū kekahi i nā mea haumia e like me ka hao, aluminika, kalapona, sulfur a me ka phosphorus ma nā ʻano like ʻole.I ka hao a me ka ʻoihana kila, hoʻohana ʻia ia e like me ka mea hoʻohui calcium, deoxidizer, desulfurizer a me denaturant no nā mea hoʻohui ʻole.Hoʻohana ʻia ia ma ke ʻano he inoculant a denaturant i ka ʻoihana hao.
Hoʻohana:
E like me ka deoxidizer pūhui (deoxidization, desulphurization a me ka degassing) Hoʻohana ʻia i ka hana kila, hoʻoheheʻe ʻia.Ma ke ʻano he inoculant, hoʻohana ʻia i ka hana hoʻolei ʻana.
Kūlana kino:
ʻO ka ʻāpana ca-si he ʻeleʻele hina i ʻike ʻia me ke ʻano o ka palaoa.Puʻupuʻu, palaoa a me ka pauka.
Pūʻolo:
Hiki i kā mākou hui ke hāʻawi i nā ʻano huapalaoa i kuhikuhi ʻia e like me nā koi o ka mea hoʻohana, i hoʻopili ʻia me ka lole palaki a me ka ʻeke ton.

Hōʻike ʻia nā mea haumia ʻē aʻe e like me nā kumu like ʻole.Eia kekahi, ma ke kumu o ka silicon-calcium alloys, ua hoʻohui ʻia nā mea ʻē aʻe e hana i nā alloys composite ternary a i ʻole multi-element.E like me Si-Ca-Al;Si-Ca-Mn;ʻO Si-Ca-Ba, a me nā mea'ē aʻe, hoʻohanaʻia e like me deoxidizer, desulfurizer, denitrification agent a me ka mea hoʻohui i ka hao a me ke kila kila.
No ka mea he pili ikaika ka calcium me ka oxygen, sulfur, hydrogen, nitrogen a me carbon i ke kila hoʻoheheʻe ʻia, hoʻohana nui ʻia nā alloys silicon-calcium no ka deoxidation, degassing a me ka hoʻopaʻa ʻana o ka sulfur i ke kila hoʻoheheʻe.Hoʻopuka ka silikona calcium i ka hopena exothermic ikaika ke hoʻohui ʻia i ke kila hoʻoheheʻe.Hoʻololi ka calcium i ka mahu calcium i loko o ke kila hoʻoheheʻe ʻia, he hopena hoʻoulu ʻia i ke kila hoʻoheheʻe ʻia a he pōmaikaʻi i ka lana ʻana o nā mea hoʻohui ʻole.Ma hope o ka hoʻohemo ʻana o ka silicon-calcium alloy, hoʻopuka ʻia nā mea hoʻohui non-metallic me nā mea nui a maʻalahi e lana, a hoʻololi pū ʻia ke ʻano a me nā waiwai o nā mea hoʻohui ʻole.No laila, hoʻohana ʻia ka silicon-calcium alloy e hana i ke kila maʻemaʻe, ke kila kiʻekiʻe me ka haʻahaʻa oxygen a me ka sulfur content, a me ke kila hana kūikawā me ka haʻahaʻa haʻahaʻa o ka oxygen a me ka sulfur content.ʻO ka hoʻohui ʻana o ka silicon-calcium alloy hiki ke hoʻopau i ka nodulation o ke kila me ka alumini e like me ka deoxidizer hope loa ma ka nozzle ladle, a me ka pani ʻana o ka nozzle o ka tundish o ka hoʻolei mau ʻana |hana hao.I ka ʻenehana hoʻomaʻemaʻe ma waho o ka umu o ke kila, hoʻohana ʻia ka pauka silicon-calcium a i ʻole ka uea kumu no ka deoxidation a me ka desulfurization e hōʻemi i ka ʻike o ka oxygen a me ka sulfur i ke kila i kahi haʻahaʻa haʻahaʻa;hiki iā ia ke hoʻomalu i ke ʻano o ka sulfide i ke kila a hoʻomaikaʻi i ka helu hoʻohana o ka calcium.I ka hana ʻana i ka hao hao, ma waho aʻe o ka deoxidation a me ka hoʻomaʻemaʻe ʻana, ke pāʻani nei ka silicon-calcium alloy i kahi hana inoculating, e kōkua ana i ka hana ʻana i ka graphite maikaʻi a i ʻole spherical;hana i ka graphite i ka hina hina hao e like me ka mahele, hoemi i ka whitening tendency;a hiki ke hoʻonui i ke silika a me ka desulfurize, Hoʻonui i ka maikaʻi o ka hao.
