Mea hoʻololi kila calcium silikon Si40 Fe40 Ca10

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 hoʻoheheʻe ʻia ʻana o ka silicon-calcium alloy, hoʻopuka ʻia nā mea komo 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 ladle nozzle, a me ka pani ʻana o ka nozzle o ka tundish o ka hoʻolei mau ʻana | hana hao. I ka ʻenehana hoʻomaʻemaʻe kila ma waho o ka umu, 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 loko o ke kila i kahi haʻahaʻa haʻahaʻa; hiki iā ia ke hoʻomalu i ke ʻano o ka sulfide i ke kila a hoʻomaikaʻi i ka hoʻohana ʻana o ka calcium. I ka hana ʻana i ka hao hao, ma waho aʻe o ka deoxidation a me ka hoʻomaʻemaʻe ʻana, hoʻokani ʻo silicon-calcium alloy i kahi hana inoculating, e kōkua ana i ka hana ʻana i ka graphite fine-grained a spherical; hana i ka graphite i ka hina hina hao e like me ka mahele ana, hoemi i ke ano o ka whitening; a hiki ke hoʻonui i ke silika a me ka desulfurize, Hoʻonui i ka maikaʻi o ka 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.

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.
