Khoom Description
Tsawg aluminium ferrosilicon txheem thaiv yog ib hom silicon alloy uas tau siv dav hauv kev lag luam steel. Nws yog tsim los ntawm kev sib txuas hlau, silicon, thiab txhuas hauv ib qho piv txwv thiab yaj lawv ua ke. Qhov tshwm sim yog cov khoom lag luam uas muaj cov thermal conductivity thiab hluav taws xob zoo heev, ua rau nws yog cov khoom siv zoo tshaj plaws rau kev siv ntau yam kev lag luam.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm qis aluminium ferrosilicon txheem thaiv yog tias nws muaj peev xwm tiv taus corrosion thiab tuaj yeem tiv taus qhov kub thiab txias. Qhov no ua rau nws yog qhov kev xaiv nrov rau kev siv hauv steelmaking, qhov twg nws yog siv los tshem tawm impurities ntawm cov hlau thiab txhim kho nws tag nrho zoo. Nws kuj yog siv los ua tus neeg sawv cev deoxidizing hauv kev tsim cov hlau thiab lwm yam alloys.
Lwm qhov txiaj ntsig ntawm qis aluminium ferrosilicon txheem thaiv yog tias nws yog tus pheej yig thiab yooj yim los tsim. Qhov no ua rau nws yog qhov kev xaiv txaus nyiam rau cov tuam txhab nrhiav kom txo lawv cov nqi tsim khoom thaum tseem tuav cov khoom zoo. Tsis tas li ntawd, nws yog ib puag ncig tus phooj ywg, vim nws tuaj yeem tsim tau siv cov khoom siv rov ua dua tshiab thiab tsis tsim cov khoom tsim kev puas tsuaj lossis emissions.
Zuag qhia tag nrho, qis aluminium ferrosilicon txheem thaiv yog cov khoom siv ntau yam uas muaj ntau yam txiaj ntsig rau kev lag luam uas nws siv. Nws cov khoom sib xyaw ua ke tshwj xeeb ua rau nws yog cov khoom siv zoo tshaj plaws rau kev siv steelmaking, nrog rau lwm yam kev lag luam xws li kev tsim cov txhuas, magnesium, thiab lwm yam hlau.
Nyob rau hauv xyoo tas los no, qhov kev thov rau qis aluminium ferrosilicon txheem thaiv tau loj hlob, uas tau tsav los ntawm kev xav tau ntau ntxiv rau cov khoom siv hlau zoo hauv cov teb chaws xws li Tuam Tshoj, Is Nrias teb, thiab Brazil. Yog li ntawd, ntau lub tuam txhab hauv kev lag luam ferrosilicon tau nce lawv lub peev xwm ntau lawm kom tau raws li qhov xav tau loj hlob no.
Ib qho ntawm cov laj thawj rau qhov muaj koob meej ntawm cov txhuas ferrosilicon txheem thaiv yog nws lub peev xwm los txhim kho lub cev ntawm cov hlau.
Los ntawm kev tshem tawm impurities thiab txo cov pa oxygen hauv cov hlau, nws tuaj yeem txhim kho nws lub zog, ductility, thiab lwm yam khoom siv kho tshuab. Qhov no tau ua rau muaj kev xav tau ntau ntxiv rau cov khoom ferrosilicon hauv tsheb, kev tsim kho, thiab lwm yam kev lag luam.
