He aha te ferrosilicon?

Ko te Ferrosilicon he ferroalloy he rino me te silicon.Ko te Ferrosilicon he koranu rino-siliconi i hangaia ma te whakarewa i te tiihi, te kowhatu rino, me te kiripaka (he silica ranei) i roto i te oumu hiko.I te mea he ngawari te whakakotahi o te silicon me te hāora ki te hauhautanga silicon, ka whakamahia te ferrosilicon hei deoxidizer i roto i te hanga maitai.I te wa ano, na te mea ka nui te wera o te SiO2, he pai ano te whakanui ake i te pāmahana o te rino whakarewa i te wa o te deoxidation.I te wa ano, ka taea hoki te whakamahi i te ferrosilicon hei taapiri huānga whakakotahi, ka whakamahia nuitia ki te rino hanganga koranu iti, te rino 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.

rongo1

Ko te Ferroalloy he rino me te silicon (ma te whakamahi i te silica, te maitai, me te coke hei rauemi mata, ko te silicon kua whakahekehia i te teitei o te 1500-1800 nga nekehanga ka whakarewahia ki te rino whakarewa hei hanga i te koranu ferrosilicon).He momo koranu nui i roto i te umanga whakarewa.

Whakaahuatanga hua
(1) Ka whakamahia hei deoxidizer me te whakakotahi i te umanga rino.Hei whiwhi i te hanganga matū whai mana me te whakapumau i te kounga o te maitai, i te waahanga whakamutunga o te rino me whakakorehia.Ko te hononga matū i waenga i te silicon me te hāora he tino nui, No reira ko te ferrosilicon he deoxidizer kaha e whakamahia ana i roto i te parataiao me te whakamaarama whakamaaramatanga o te hanga maitai.Tāpirihia he nui o te silicon i roto i te maitai, ka taea te whakapai ake i te kaha, te pakeke me te elasticity o te maitai.

(2) Ka whakamahia hei kaihoko nucleating me te spheroidizing agent i roto i te ahumahi rino.Ko te rino te rino he momo taonga whakarewa ahumahi hou , He iti ake te utu i te rino, ngawari ki te rewa te para, me te pai o te mahi whakarewa me te kaha o te ruihi he pai ake i te maitai.Ina koa ko te rino nodular, Ko ona ahuatanga miihini kei te tata ranei ki nga taonga miihini o te maitai.Taapirihia he nui o te silicon i roto i te rino ka taea te aukati i te hanga o te rino, te whakatairanga i te rerenga o te graphite me te carbide spheroidizing.No reira i roto i te hanga rino nodular, ko te ferrosilicon tetahi momo inokulent nui ( Awhina ki te wehe i te kauwhata) me te kaihoko spheroidizing.
