Kev siv steel:
Hlau yog tsuas yog siv hauv kev tsim kho, tshuab, tsheb, lub zog, nkoj tsim, khoom siv hauv tsev, thiab lwm yam. Ntau tshaj 50% ntawm cov hlau yog siv hauv kev tsim kho. Kev tsim kho steel feem ntau yog rebar thiab xaim pas nrig, thiab lwm yam, feem ntau cov vaj tse thiab cov vaj tse, vaj tse steel noj feem ntau yog ob npaug ntawm cov hlau siv hauv kev tsim vaj tsev, yog li kev lag luam vaj tsev muaj kev cuam tshuam ntau dua rau kev siv steel; machinery, tsheb, khoom siv hauv tsev, steel xav tau accounted rau qhov feem ntawm steel noj nyob rau hauv li ntawm 22%. Mechanical steel rau phaj-raws li, concentrated nyob rau hauv kev ua liaj ua teb machinery, tshuab cuab yeej, hnyav machinery thiab lwm yam khoom; Cov khoom siv hauv tsev steel rau cov ntawv txias txias, cov ntawv kub galvanized, silicon steel ntawv, thiab lwm yam., concentrated nyob rau hauv tub yees, tshuab ntxhua khaub ncaws, cua txias thiab lwm yam khoom dawb; automotive steel ntau yam yog ntau, steel yeeb nkab, steel, profiles, thiab lwm yam. yog siv, thiab tawg nyob rau hauv lub tsheb qhov chaw, xws li cov qhov rooj, bumpers, pem teb daim hlau, thiab lwm yam. dawb khoom tsim thiab muag, automotive manufacturing peev, automotive ntau lawm thiab thov kom soj ntsuam cov kev xav tau steel qhov teeb meem.
Lub ntsiab ntau yam ntawm steel:
Hlau yog hlau thiab carbon, silicon, manganese, phosphorus, sulfur thiab ib tug me me ntawm lwm yam ntsiab lus muaj li ntawm alloys. Ntxiv nrog rau cov hlau, cov ntsiab lus carbon plays lub luag haujlwm tseem ceeb hauv cov khoom siv hlau, yog li nws tseem hu ua hlau-carbon alloy. Feem ntau muaj ntau yam hauv qab no:
Npua hlau Crude steel Kub dov kauj & phaj nruab nrab-Thick phaj
Deformed Bar H Beam Seamless Steel Yeeb Nkab Hlau Qws
1.pig hlau: ib hom hlau thiab carbon alloy, cov ntsiab lus carbon feem ntau yog 2% -4.3%, tawv thiab nkig, siab thiab hnav tsis kam
2.crude steel: npua hlau oxidized thiab ua tiav los ntawm cov ntsiab lus carbon feem ntau tsawg dua 2.11% ntawm cov hlau-carbon alloy. Piv nrog npua hlau, muaj zog dua, zoo plasticity thiab ntau dua toughness.
3.kub dov coil: slab (tsuas yog nruam nruam casting slab) raws li cov khoom siv raw, rhuab los ntawm lub qhov cub cua sov (lossis txawm tias cov cua sov ua kom sov), los ntawm roughing thiab xov zeb dov los ntawm cov sawb.
4.medium-thick phaj: yog lub ntsiab ntau lawm ntau yam ntawmhlau phajthiab sawb hlau, tuaj yeem siv rau kev tsim kho tshuab, txuas hniav, nkoj tsim, thiab lwm yam.;.
5.deformed bar: rebar yog ib qho me me ntawm cov hlau, feem ntau hu ua kub dov ribbed steel bar;
6.H-beam: H-beam cross-section zoo li tsab ntawv "H". Nrog muaj zog dabtsi yog khoov, lub teeb yuag qauv, kev tsim kho yooj yim thiab lwm yam zoo. Feem ntau yog siv rau cov tsev loj, cov choj loj, cov khoom siv hnyav.
7.seamless steel yeeb nkab: seamless steel yeeb nkab yog perforated los ntawm tag nrho cov puag ncig steel, tsis muaj welds ntawm qhov chaw, tsuas yog siv nyob rau hauv lub tsim ntawm cov yam ntxwv thiab mechanical qhov chaw, xws li roj drilling rods, tsheb tsav shafts, boiler raj, thiab lwm yam.;.
8.cev rod: Loj ntev, siab qhov tseeb thiab nto zoo, hlau loj kam rau ua precision, tsuas yog siv rau cov khoom hlau ua.
Cov khoom siv hlau thiab smelting:
1. steel ntau lawm cov ntaub ntawv:
Hlau ore: Cov khoom siv hlau thoob ntiaj teb no feem ntau yog nyob hauv Australia, Brazil, Russia thiab Tuam Tshoj.
Roj: feem ntau coke, coke yog tsim los ntawm coking thee, yog li cov khoom ntawm coke yuav cuam tshuam los ntawm tus nqi coke.
2. Hlau thiab hlau smelting:
Hlau thiab steel smelting txheej txheem tuaj yeem muab faib ua cov txheej txheem ntev thiab cov txheej txheem luv luv, peb lub teb chaws mus rau cov txheej txheem ntev, ntev thiab luv luv feem ntau yog hais txog cov txheej txheem steelmaking sib txawv.
Ntev txheej txheem tseem ceeb hlaumaking, steelmaking, nruam casting. Cov txheej txheem luv luv tsis tas yuav mus dhau los ntawm kev tsim cov hlau, ncaj qha nrog lub tshuab hluav taws xob yuav raug smelted rau hauv cov hlau tsis huv.
