Production Waste metallurgy

Ko tētahi o nga rāngai matua o te ōhanga ko te metallurgy. E whakarato ana i te rauemi raw, maha atu ahumahi. Ferrous me konganuku kore-ferrous e hiahiatia tata nga wahi katoa. Na kei te whakanui ake i te utu o enei rauemi raw katoa ra. utu Energy, o te akoranga, i te pānga nui i runga i te utu o ngā hua maitai. Ko te wāhi nui i roto i te hanganga me te hanga o te ururua nui utu.

A i roto i te metallurgy o ratou tino nui. noho ratou wāhi nui, me te kupu paru i te rangi pūhui paitini, te wai me te oneone. A i te wa ano i runga i o ratou utu whare noho, te rokiroki me te transportation o te mana nui i runga i te utu o te hanga o hinonga metallurgical. Ko roto i enei kai i te rota o ngā āhuatanga e taea te whakamahi rite ngā rauemi raw tuarua. A, no te huarahi o te ariki, e taea te tahuri taua ururua metallurgical ki te puna o te moni.

Ēnei ururua hua i te tango, o parahi, maka rino ferroalloys ranei. A kia ara teitei i roto i a ratou ake i roto i te tokahuke tūturu taua te ihirangi o wāhanga kohuke rerekē, e ai ngā rino,. A e tika ana ki te iti ako o te hanganga me ngā āhuatanga o sludges reira ko te raruraru ki to ratou anō.

Haere i te iti rawa te para steelmaking. Ēnei hanga ururua tukurua i roto i maha mira maitai me wheketere tahuri ki para taonga. Hoki tenei whakaaro whiwhi te "maroke" hua wehenga autō i muri i kuru o te para. He hua whai hua i whiwhi i muri i tenei maimoatanga, karaka toto whakaaro whakarewa nui me māpele o whakarewa me te karaihe takawai. hanganga para Iron-taonga he iti āhua. A, kia rite ki te hua o te haamaitairaa i te otaota sinter o taranata o para hua e pā ana ki 40 kg o whakarewa. Ko te hua ururua toe, e i roto i whai mai iti anake ranei waikura rino e whangai ki te mata.

Ko reira te mea he pai ake te hangarau mō te fakatupulaki o te para maitai. Ki te awhina o enei ururua taea whiwhi toru hua. Ko te tuatahi ko te hua whakarewa. E riro te reira e pā ana ki 10% o te papatipu para. Ko reira, haunga konganuku rino, kei poke iti karaihe, silicates me pākawa waro. Tona briquetted ka tonoa ki te kaitahi tuarua. Ko te tuarua ko te hua waikura kotakota-rino. Ko reira e pā ana ki 22% o te katoa. Iron i roto i tenei hua he iti moka. Hoki te wahi tino, ngā reira o ngā kohuke. Tenei wustite, magnetite, maghemit, goethite, hematite, kotakota hydrated, rino, me pākawa waro konupūmā, me te konupora me te konupūmā ferrites. Ka taea te whakamahi i tēnei hua rite te rauemi kai te kounga teitei i roto i te hanga o te sinter rino fluxed. Na te toenga, i te mea e pā ana ki 68% taka i runga i te hua takawai. Kei o kohuke Ko tōna wahi matua: silicates, spinels, tridymite, karaihe magnesium me hua kotakota Hydration. e kore ano hoki e enei hua ururua i roto i noa. whakamahia hua magnesium te nuinga i roto i te hanga, sima ētahi atu hua cementitious ranei.

Ka taea hoki e koe te tango i te hanga para ferromanganese, e roto i maha wähanga faufaa. Tenei karaka toto ferromanganese me konganuku rino, silicates, waihā, waikura māpele, konupora me pākawa waro rino, karaihe magnesium, me ngā hua o tona whātioatanga. Kua whakawhanakehia Scientists he tikanga e ai te whakahaere maroke mahara kukū o enei tāoke. Ka rite ki te hua o enei hua ururua taea te hanga o ngā hua e toru.

Ko te tuatahi o enei ko te rino konupora kareti. O te papatipu tapeke o te para e taea te tiki i te reira ki runga ki te 17%. Tenei hua kei wahi autō, me te kore-autō o rino, konupora, Cohen rino, me te ngā alloys ki rerekē tirotiro o te konupora me te rino, me o ratou waikura, ngā waihā. Whakamahia tēnei hua e taea kia hoki te hanga o te ferromanganese.

Ko te hua tuarua ko te onepu magnesium. taka hawhe o te katoa taimaha para ki runga ki a ia. Kei te nuinga o te kiripaka, cristobalite, tridymite, karaihe me silicates onepu magnesium. Mai i reira ka taea e koe te whakaputa i silicomanganese whakamahi i te reira rite te rauemi whare ranei.

Ko te toe 33% mai i te puehu paru-pākawa waro. Kei te tito te reira o silicates wehea miro, pākawa waro, karaihe me ētahi atu kohuke. Kei te whakamahia i tēnei puehu mō te sima production. He maha atu o tenei momo o te ururua, e taea whai hua te iwi.
