Silicon Calcium Hlau yog dab tsi?
Silicon calcium hlau yog cov khoom tsim los ntawm silicon thiab calcium ntsiab lus, nrog lub tes tsho sab nrauv.
Cov txiaj ntsig ntawm Ntxiv Silicon Calcium Hlau Thaum Tapping
Ntxiv nws thaum lub sij hawm tapping cov khoom siv yooj yim oxidizable cov ntsiab lus thiab cov kab kawm tau zoo, txo tus nqi ntawm cov hlau ntxiv. Kev siv cov khoom siv no txhim kho qhov zoo ntawm cov hlau molten, txo cov tiam ntawm kev sib koom ua ke, thiab txhim kho lub xeev pouring. Silicon calcium hlau txhim kho cov txiaj ntsig ntawm alloys, txo tus nqi ntawm steelmaking, thiab txhim kho cov castability ntawm molten steel. Nws muaj txiaj ntsig zoo rau kev kho thiab tswj cov ntsiab lus ntawm cov ntsiab lus oxidizable yooj yim thiab cov kab mob, txhim kho cov txiaj ntsig zoo ntawm alloy, txo cov nqi smelting, shortening smelting lub sij hawm, thiab tswj kev muaj pes tsawg leeg.
Calcium Kho Thaum Hlau Pub
Thaum ua cov khoom ntshiab calcium hlau, cov tshuaj tiv thaiv nrog molten hlau yog khaus ntau dua nrog silicon calcium hlau. Calcium kho cov haujlwm xws li kev pub mis qhov tob thiab xaim ceev ceev yuav tsum tau ua tib zoo tswj. Vim yog lub siab vapor siab ntawm cov khoom ntshiab calcium hlau, cov hlau yuav tsum tau muab sib sib zog nqus los tiv thaiv cov evaporation ntawm calcium. Ob txoj kev ntsuas yog siv: nce lub thickness ntawm lub tes tsho steel los tiv thaiv kev ua kom tiav ntxov uas yuav txo qhov tob ntawm calcium tso tawm, thiab ua kom cov hlau pub ceev kom cov hlau nkag mus rau txheej slag thiab ncav cuag qhov tob txaus, txo oxidation ntawm calcium los ntawm slag, nce calcium nqus los ntawm molten steel, thiab txhim kho cov calcium rov qab.
Cov lus nug nquag
Vim li cas ntxiv silicon calcium hlau thaum tapping?Txhawm rau txhim kho alloy yield, txo cov kev suav nrog, txhim kho castability, thiab tswj tau yooj yim oxidizable ntsiab zoo.
Vim li cas thiaj yuav tsum tau cov calcium hlau ntshiab kom noj tob?Nws lub siab vapor siab ua rau ntuj evaporation; kev pub mis sib sib zog nqus tiv thaiv cov yaj ua ntej ua ntej thiab ua rau kom muaj calcium ntxiv.
Calcium rov zoo li cas?Los ntawm kev nce lub tes tsho tuab thiab xaim pub ceev kom cov hlau nkag mus rau txheej slag ua ntej tso calcium.
Dab tsi yog cov txiaj ntsig tseem ceeb ntawm silicon calcium hlau ntawm molten steel zoo?Nws txhim kho qhov zoo ntawm cov hlau molten, txo cov tiam ntawm inclusions, txhim kho lub xeev pouring, thiab yog qhov zoo rau kev kho thiab tswj tau yooj yim oxidizable ntsiab lus thiab kab kawm, ho txhim kho alloy yield thiab shortening smelting lub sij hawm.
Vim li cas cov tshuaj tiv thaiv ntawm cov khoom ntshiab calcium hlau ntau dua li silicon calcium hlau?Vim yog lub siab vapor siab ntawm cov khoom ntshiab calcium hlau, calcium kev kho cov hauj lwm xws li pub qhov tob thiab xaim ceev ceev yuav tsum tau ua tib zoo tswj kom tsis txhob ntuj evaporation ntawm calcium.
