Kev lag luam Pure Iron: Ib qho kev piav qhia
Kev lag luam cov hlau ntshiab, feem ntau hu ua CPI, yog ib lo lus siv los piav txog hom hlau uas tau ua kom zoo rau qib siab ntawm purity, feem ntau rau kev lag luam thiab kev lag luam. Tsab ntawv xov xwm no yog npaj los muab cov lus qhia dav dav ntawm kev lag luam hlau ntshiab, npog nws lub ntsiab lus, txheej txheem tsim khoom, lub cev thiab tshuaj lom neeg, kev siv, thiab cov qauv yav tom ntej.
Txhais thiab yam ntxwv
Kev lag luam cov hlau ntshiab yog cov khoom siv uas tau ua kom zoo kom tshem tawm cov impurities xws li carbon, silicon, manganese, phosphorus, sulfur, thiab lwm yam kab kawm mus rau theem teev tseg. Lub purity ntawm CPI yog feem ntau qhia nyob rau hauv cov nqe lus ntawm nws residual impurity cov ntsiab lus, nrog qis impurity theem qhia tias siab dua purity. Cov yam ntxwv tseem ceeb ntawm CPI yog nws cov purity siab, uas ua rau muaj kev txhim kho lub cev thiab tshuaj lom neeg zoo dua piv rau cov hlau tsis zoo los yog tsawg dua refined.
Cov txheej txheem ntau lawm
Kev tsim cov hlau ntshiab hauv kev lag luam muaj ob peb kauj ruam, suav nrog kev mining, refining, thiab ua. Nov yog cov ncauj lus kom ntxaws ntawm txhua kauj ruam:
Mining
Thawj kauj ruam hauv kev tsim CPI yog mining hlau ore, uas yog ib txwm tshwm sim ntxhia uas muaj hlau ua ke nrog oxygen thiab lwm yam khoom. Feem ntau hom hlau ore yog hematite (Fe₂O₃) thiab magnetite (Fe₃O₄). Kev lag luam mining feem ntau koom nrog kev rho tawm cov hlau ore los ntawm qhov qhib mines lossis cov mines hauv av siv cov txheej txheem drilling thiab blasting.
Kev kho kom zoo
Thaum cov hlau ore raug rho tawm, nws dhau los ua cov txheej txheem refining kom tshem tawm impurities thiab hloov mus rau hauv daim ntawv siv tau. Cov txheej txheem ua kom zoo tshaj plaws yog txoj kev tawg rau qhov cub, uas suav nrog cua sov cov hlau ore nrog coke (cov roj carbon nplua nuj) thiab limestone (cov dej ntws uas tshem tawm cov impurities) hauv qhov cub tawg. Qhov kub thiab txo qhov cua ua rau cov hlau oxide nyob rau hauv cov ore kom txo tau cov hlau hlau, thaum impurities xws li sulfur thiab phosphorus raug tshem tawm raws li gases los yog slags.
Secondary Refining
Tom qab cov txheej txheem blasting rauv, cov hlau yuav dhau mus rau kev kho kom zoo ntxiv kom huv ntxiv. Qhov no tuaj yeem koom nrog cov txheej txheem xws li hluav taws xob arc rauv refining, nqus degassing, lossis ladle furnace refining. Cov txheej txheem no pab tshem tawm cov impurities ntxiv thiab txhim kho cov hlau zoo.
Kev ua haujlwm
Thaum kawg, cov hlau ua kom zoo yog ua tiav rau hauv ntau yam ntaub ntawv xws li tuav, ntawv, strips, daim hlau, thiab cov xov hlau. Qhov kev ua no yuav suav nrog kub dov, txias dov, forging, los yog extruding hlau kom ua tiav cov duab thiab loj.
Physical thiab Chemical Properties
Kev lag luam ntshiab hlau muaj ntau yam ntawm lub cev thiab tshuaj lom neeg uas ua rau nws haum rau ntau yam kev siv. Nov yog qee qhov tseem ceeb ntawm CPI:
Lub cev muaj zog
Qhov ntom: Qhov ceev ntawm CPI yog kwv yees li 7.87 g / cm³, uas zoo ib yam li lwm cov hlau.
Melting Point: Lub melting point ntawm CPI yog 1538 degree, uas yog kuj siab piv rau lwm yam hlau.
Thermal conductivity: CPI muaj cov thermal conductivity zoo, ua rau nws tsim nyog rau cov ntawv thov uas hloov hluav taws xob tseem ceeb.
Magnetic Properties: CPI yog ferromagnetic, txhais tau tias nws tuaj yeem sib nqus thiab siv rau hauv kev siv xws li hluav taws xob motors thiab generators.
Chemical Properties
Corrosion Resistance: CPI muaj kev tiv thaiv corrosion zoo hauv ntau qhov chaw, tab sis nws yuav xav tau cov txheej txheem ntxiv los yog kev kho mob los tiv thaiv nws ntawm corrosion nyob rau hauv ib puag ncig hnyav heev.
Reactivity: CPI kuj tsis tshua muaj tshwm sim, tab sis nws tuaj yeem hnov mob nrog oxygen los tsim cov hlau oxide (xeb) yog tias raug huab cua ntub.
Daim ntawv thov
Kev lag luam ntshiab hlau yog siv ntau yam kev siv vim nws siab purity, zoo lub cev thiab tshuaj, thiab tus nqi qis. Nov yog qee qhov kev siv ntawm CPI:
Kev siv hluav taws xob thiab hluav taws xob
CPI feem ntau siv rau hauv kev siv hluav taws xob thiab hluav taws xob vim nws cov hluav taws xob zoo heev thiab cov khoom sib nqus. Nws yog siv rau hauv kev tsim cov transformers, generators, motors, thiab lwm yam khoom siv hluav taws xob. CPI kuj tseem siv rau hauv kev tsim cov khoom sib nqus xws li cov hlau nplaum ruaj khov thiab cov ntaub ntawv sib nqus.
