Npua hlau yog siv rau steel ua, Foundries, Alloy ua, hauv tsheb castings thiab lwm yam hlau raws li castings.
npua hlau siv tau dab tsi?
Npua hlau yog ib qho khoom siv ntawm cov hlau kub, tau los ntawm cov hlau ore los yog cov khoom siv rov ua dua tshiab, thiab nws tau ua tiav nrog lub qhov cub tawg lossis hluav taws xob arc rauv. Npua hlau yog siv los ua ib qho raw khoom rau hlau ua thiab feem ntau ntawm cov khoom no yog imported.
Lub hom phiaj ntawm kev siv npua hlau hauv steelmaking yog dab tsi?
Basic oxygen steelmaking yog ib txoj hauv kev ntawm thawj steelmaking nyob rau hauv uas carbon-nplua nuj molten npua hlau (cov hlau tsim nyob rau hauv lub qhov cub tawg) yog ua rau hlau. Tshuab pa oxygen los ntawm molten npua hlau txo cov pa roj carbon ntsiab lus ntawm cov hlau thiab hloov nws mus rau hauv cov hlau tsis muaj carbon
npua hlau yog dab tsi thiab nws lub ntsiab yog dab tsi?
Npua hlau tseem hu ua cov hlau tsis huv. Nws yog tau los ntawm lub qhov cub smelting nyob rau hauv daim ntawv ntawm oblong blocks thiab muaj cov pa roj carbon ntau ntawm 3.5 - 4.5vim nws muaj 90% ntawm cov hlau. Nws yog tsim los ntawm smelting hlau ore nrog high-carbon roj thiab reductant xws li, coke feem ntau nrog limestone uas pab flux.
Peb lub zog ntawm npua hlau yog dab tsi?
Npua hlau muaj cov ntsiab lus siab carbon, feem ntau 3.5% - 4.5% nrog rau cov feem pua me me ntawm silicon, sulfur, manganese thiab phosphorous. Qhov no ua rau nws nkig thiab tsuas yog siv tau tiag tiag rau resmelting los ua hlau cam, wrought hlau los yog, niaj hnub no, steel.
