Cov yam ntxwv ntawm silicon calcium cored hlau
Muaj ntau hom cored xov hlau, tab sis cov xov hlau silicon calcium cored yog dav siv, thiab cov neeg uas paub thiab nkag siab txog cov xov hlau silicon calcium cored kuj nce. Raws li cov chaw tsim khoom cored hlau, peb lub tuam txhab tuaj yeem tsis tsuas yog pom zoo thiab muab ntau hom cored hlau raws li qhov xav tau ntawm cov neeg siv, tab sis kuj, los ntawm kev sau cov kev nkag siab ntawm cored hlau rau ntau xyoo, piav qhia cored hlau rau koj kom ntxaws los pab koj. nkag siab txog silicon calcium cored hlau.
Cored hlau yog cov khoom siv linear siv los ua kom cov hlau ua kua. Nws yog tsim los ntawm cov txheej txheem hmoov txheej thiab cov ntaub qhwv ua los ntawm cov sawb steel ntawv qhwv rau saum npoo ntawm cov tub ntxhais hmoov txheej. Thaum siv, los ntawm cov xaim pub tshuab pob tub ntxhais txuas ntxiv mus rau hauv lub ladle, thaum tus neeg xyuas pib mus rau hauv lub hnab ntim tom qab yaj, lub hau npog ntawm cov tub ntxhais cov hmoov txheej hauv kev sib cuag ncaj qha nrog cov tshuaj tiv thaiv hlau molten, thiab los ntawm cov nyhuv ntawm argon nplawm. , yog li nws tuaj yeem ua tiav lub hom phiaj ntawm deoxidization, desulphurization thiab tshem tawm cov kev suav nrog, txhawm rau txhim kho qhov zoo thiab kev ua haujlwm ntawm cov hlau. Nws tuaj yeem pom tau tias txhawm rau ua kom zoo huv si molten hlau los ntawm cored hlau, ob qho xwm txheej yuav tsum tau ntsib: cov khoom xyaw nquag hauv cov hmoov txheej yuav tsum muaj peev xwm nkag rau hauv txhua lub ces kaum ntawm cov hlau molten; Lub active ingredient nyob rau hauv lub core hmoov txheej muaj ib tug loj txaus lub peev xwm mus lob oxygen thiab sulfur atoms.
Cov calcium nyob rau hauv calcium silicon packet core hmoov yog ib yam ntawm cov khoom siv feem ntau siv, txawm hais tias nws yog ib hom deoxidizer, tab sis vim lawv lub teeb, nrog rau qhov qis melting point, thiab nws muaj npuas nyob rau hauv qhov kub thiab txias, yog li tsuas yog nrog rau hlau calcium hmoov txheej yuav tshwm sim raws li ib pob ntawm core core pob neeg xyuas pib tau nyuam qhuav raug xa mus rau hauv lub refining rauv pib hlawv tshwm sim, thiab pob ntawv tub ntxhais mus rau hauv tsawg dua steel nyob rau hauv nruab nrab ntawm cov nram qab no, Nws tsis tuaj yeem ua tiav cov txiaj ntsig zoo tagnrho, thiab combustion ntawm core hmoov txheej tsis tuaj yeem ua tiav qhov zoo tshaj plaws purification nyhuv nyob rau hauv cov xwm txheej zoo li no, tab sis kuj ua rau cov khoom siv calcium pov tseg nrog tus nqi siab.
