kalapona kiʻekiʻeferrochromeʻO ia kekahi o nā ferroalloys maʻamau i hana ʻia a aneane hoʻohana wale ʻia i ka hana ʻana i ke kila kila a me nā kila chromium kiʻekiʻe.Hana nui ʻia ka hana ʻana ma nā ʻāina me ka lako o ka chromite ore.Hāʻawi pū ka uila a me nā mea hoʻemi i ke ola o ka ferrochrome kalapona kiʻekiʻe.ʻO ka ʻenehana hana maʻamau i hoʻohana ʻia, ʻo ia ka hoʻoheheʻe ʻana i ke ahi i loko o nā kapuahi AC, ʻoiai ʻo ka hoʻoheheʻe ʻana i nā kapuahi hāmama i nā kapuahi DC e maʻa mau nei.Hoʻohana ʻia kahi ala ʻenehana ʻoi aʻe e loaʻa ana kahi kaʻina prereduction ma ka nui nui e hoʻokahi mea hana.Ua lilo nā kaʻina hana i ka ikehu a me ka hoʻohana ʻana i nā kaʻina hana holomua e like me ka prereduction, preheating, agglomeration of ore, a me ka hoʻohana kinoea CO.Hōʻike nā mea kanu i hoʻokomo hou ʻia i nā pilikia e hiki ke mālama ʻia e pili ana i ka haumia o ke kaiapuni a me ke olakino ʻoihana.
Ma luna o 80% o ka ferrochrome puka honua i hoʻohana ʻia i ka hana ʻana i ke kila kila.Pili ke kila kila i ka chromium no kona helehelena a me kona kū'ē i ka ʻino.ʻO ka awelika o ka chromium ma ke kila kila he 18%.Hoʻohana pū ʻia ka FeCr inā makemake ʻia e hoʻohui i ka chromium i ke kila kalapona.ʻO FeCr mai ʻApelika Hema i kapa ʻia ʻo "charge chrome" a i hana ʻia mai kahi ʻeleʻele chrome haʻahaʻa i hoʻohana pinepine ʻia i ka hana kila kila.ʻO ka FeCr kalapona kiʻekiʻe i hana ʻia mai ka ʻeleʻele kiʻekiʻe i loaʻa ma Kazakhstan (ma waena o nā wahi ʻē aʻe) i hoʻohana pinepine ʻia i nā noi loea e like me nā kila ʻenekinia kahi mea nui o ka Cr a i ka Fe ratio.
ʻO ka hana ʻana o Ferrochrome kahi hana hoʻohaʻahaʻa carbothermic kiʻekiʻe.Hoʻemi ʻia ka ʻohe Chrome (he oxide o ka chromium a me ka hao) e ka coke (a me ka lanahu) e hana i ka hao-chromium-carbon alloy.Hāʻawi pinepine ʻia ka wela no ke kaʻina hana mai ke arc uila i hana ʻia ma waena o nā kihi o nā electrodes i lalo o ka umu a me ka umu ahi i loko o nā kapuahi cylindrical nui loa i kapa ʻia ʻo "nā kapuahi arc submerged."E like me ka inoa, ua hoʻokomo ʻia nā electrodes kalapona ʻekolu o ka umu i loko o kahi moena o ka paʻa a me kekahi hui wai i hana ʻia me ke kalapona paʻa (coke a / a i ʻole ka lanahu), nā mea waiwai paʻa oxide (ʻo a me nā fluxes) a me ka ka wai FeCr alloy a me nā kulu paʻa lepo e hana ʻia nei.Ma ke kaʻina o ka hoʻoheheʻe ʻana, ua pau ka nui o ka uila.ʻO ka paʻi ʻana i ka mea mai ka umu ahi e hana mau ana.Ke hōʻiliʻili ʻia ka nui o ka ferrochrome i hoʻoheheʻe ʻia i loko o ke kapuahi o ka umu ahi, ua wili ʻia ka lua kīwī a wehe ʻia kahi kahawai o ka metala i hoʻoheheʻe ʻia a me ka slag i lalo o kahi pā i loko o kahi anuanu a i ʻole ka ladle.Hoʻopili ka ferrochrome i nā hoʻoheheʻe nui, i ʻoki ʻia no ke kūʻai aku a i ʻole ka hana hou ʻana.
