Cov Ntawv Thov Hlau:
Cov hlau feem ntau yog siv rau hauv kev tsim kho, tshuab, tsheb, zog, nkoj, khoom siv hauv tsev, thiab lwm yam. Ntau tshaj 50% ntawm cov hlau yog siv rau hauv kev tsim kho. Cov hlau tsim kho feem ntau yog cov hlau rebar thiab hlau rod, thiab lwm yam, feem ntau yog vaj tse thiab kev tsim kho vaj tse, kev siv hlau hauv vaj tse feem ntau yog ob npaug ntawm cov hlau siv rau hauv kev tsim kho vaj tse, yog li cov xwm txheej ntawm kev lag luam vaj tse muaj kev cuam tshuam ntau dua rau kev siv hlau; cov tshuab, tsheb, khoom siv hauv tsev, qhov kev thov hlau suav nrog qhov feem pua ntawm kev siv hlau hauv kwv yees li 22%. Cov hlau tshuab rau phaj, tsom mus rau cov tshuab ua liaj ua teb, cov cuab yeej siv tshuab, cov tshuab hnyav thiab lwm yam khoom; cov hlau siv hauv tsev rau cov ntawv txias-dov, cov ntawv kub galvanized, cov ntawv hlau silicon, thiab lwm yam, tsom mus rau cov tub yees, tshuab ntxhua khaub ncaws, cua txias thiab lwm yam khoom dawb; cov hlau tsheb muaj ntau hom, cov yeeb nkab hlau, cov hlau, cov ntaub ntawv, thiab lwm yam, thiab tawg thoob plaws hauv cov khoom siv hauv tsheb, xws li qhov rooj, lub pob tw, cov phaj pem teb, thiab lwm yam. Los ntawm kev taug qab cov cuab yeej siv tshuab, cov boilers kev lag luam thiab lwm yam tshuab hnyav, kev tsim khoom dawb thiab kev muag khoom, kev nqis peev hauv kev tsim khoom tsheb, kev tsim khoom tsheb thiab kev thov kom soj ntsuam qhov xwm txheej ntawm kev thov hlau.
cov hom hlau tseem ceeb:
Hlau yog hlau thiab carbon, silicon, manganese, phosphorus, sulfur thiab me ntsis ntawm lwm yam khoom uas ua los ntawm cov hlau sib xyaw. Ntxiv nrog rau hlau, cov pa roj carbon ua lub luag haujlwm tseem ceeb hauv cov khoom siv kho tshuab ntawm hlau, yog li nws tseem hu ua hlau-carbon alloy. Muaj cov hom hauv qab no:
Hlau npua Crude Steel Kub dov kauj & phaj Nruab nrab-Tuab Phaj
Deformed Bar H Beam Seamless Steel Yeeb Nkab Hlau Qws
1. npua hlau: ib hom hlau thiab carbon alloy, cov ntsiab lus carbon feem ntau yog 2% -4.3%, nyuaj thiab brittle, siab thiab hnav tsis kam
2. Cov hlau nyoos: cov hlau npua uas tau oxidized thiab ua tiav los ntawm cov pa roj carbon feem ntau tsawg dua 2.11% ntawm cov hlau-carbon alloy. Piv nrog cov hlau npua, nws muaj zog dua, zoo dua plasticity thiab toughness dua.
3.kub dov kauj: slab (feem ntau yog slab casting tas mus li) ua cov khoom siv raw, cua sov los ntawm lub cub tawg cua sov (lossis txawm tias cua sov cua sov), los ntawm roughing thiab finishing zeb dov los ntawm daim kab xev.
4. phaj nruab nrab-tuab: yog cov khoom tseem ceeb ntawmphaj hlauthiab cov hlau strip, siv tau rau cov qauv kho tshuab, choj, nkoj tsim, thiab lwm yam.;
5.cov hlau uas tsis zoo li qub: rebar yog ib qho me me ntawm cov hlau, feem ntau hu ua kub-kuav ribbed steel bar;
6.H-beam: H-beam cross-section zoo li tsab ntawv "H". Nrog lub peev xwm khoov tau zoo, lub cev nyhav tsis hnyav, kev tsim kho yooj yim thiab lwm yam zoo. Feem ntau siv rau cov qauv tsev loj, choj loj, thiab cov khoom siv hnyav.
7.cov yeeb nkab hlau tsis muaj seamless: cov yeeb nkab hlau tsis muaj qhov sib txuas yog perforated los ntawm tag nrho cov hlau puag ncig, tsis muaj welds ntawm qhov chaw, feem ntau yog siv rau hauv kev tsim cov khoom siv thiab cov khoom siv kho tshuab, xws li cov roj drilling rods, lub tsheb tsav shafts, boiler raj, thiab lwm yam.;
8.tus pas hlau: Ntev ntev, qhov tseeb siab thiab qhov zoo ntawm qhov chaw, qhov loj ntawm cov hlau kam rau siab precision, feem ntau yog siv rau kev ua cov khoom hlau.
Cov ntaub ntawv tsim khoom thiab kev smelting hlau:
1. cov ntaub ntawv tsim khoom hlau:
Hlau ore: Cov khoom siv hlau thoob ntiaj teb feem ntau yog nyob hauv Australia, Brazil, Russia thiab Tuam Tshoj.
Roj: feem ntau yog coke, coke yog ua los ntawm coking thee, yog li qhov kev muab coke yuav raug cuam tshuam los ntawm tus nqi ntawm coke.
2. Hlau thiab hlau smelting:
Cov txheej txheem smelting hlau thiab hlau tuaj yeem muab faib ua cov txheej txheem ntev thiab cov txheej txheem luv luv, peb lub teb chaws rau cov txheej txheem ntev, ntev thiab luv luv feem ntau yog hais txog cov txheej txheem steelmaking sib txawv.
Cov txheej txheem ntev ua hlau loj, ua hlau, thiab ua tas mus li. Cov txheej txheem luv luv tsis tas yuav dhau los ntawm kev ua hlau, ncaj qha nrog lub cub hluav taws xob yuav raug smelted rau hauv cov hlau nyoos.
