Rau steelmakers, ua tiav cov pa oxygen tsawg thiab tsis huvferrosiliconlos yog txhuas) feem ntau poob luv luv. Nkagcalcium silicon(Casi), apuas deoxidizerQhov ntawd yog Revietizing li cas peb purify steel, ua tsaug rau nws cov kev sib xyaw ntawm calcium (ca) thiab silicon (si). Ntawm no yog vim li cas nws tau dhau los ua -}} rau kev tsim cov qib siab, los ntawm alsoy} Cov qauv zoo rau cov ntawv hlau.
Cov khawv koob ntawm calcium silic silic silic silicon lus dag hauv nws synergistic dual - kev ua. Silicon ua ntej ua tus nqi, rov qab nrawm nrog yaj oxygen kom tshem tawm 60} {{9} nrawm dua li ntau ntxiv. Tab sis calcium yuav siv sij hawm txuas ntxiv: nrog kev muaj zog rau oxygen ntau dua li silicon, nws ppm, vs. 30-40 ppm nrog sio₂ rau hauv me me, kheej kheej suav nrog. Cov kev sib tw no tsis muaj zog hlau xws li ntse, angular immurities, txhawb kev nruj los ntawm 15-20% thiab weldability-tseem ceeb-tseem ceeb rau cov raj xa dej lossis tsheb.
Dab tsi ua rau nws txawm muaj nuj nqis dua yog nws cov kev hloov pauv ntawm cov txheej txheem. Hauv bof / eaf rauv, 5-30mm casi lumps ntxiv thaum tapping txiav seem los ntawm 2-3% los ntawm kev txo porosity. Rau lf Refining,Cored Hlau Casi(Pub ntawm 2 {{{{4- 4 m / s) ua kom muaj kev qhia meej, txo qis kev suav ntawm 5-10μm rau 2-3μm. Ib nrab-qhov chaw nyob nruab nrab ntawm cov neeg txhais lus hauv ib lub sijhawm 12%
Tus nqi - paub qab hau, nws yog tus yeej ib yam nkaus. Thaum 8-12 ib tuj ntawm cov hlau, casi muab ntau tus nqi ntau dua txhuas (uas raug nqi10 {-}}} Thaum xaiv cov CASI, ua ntej qib nrog 28-32% CA thiab tsawg dua lossis sib npaug ntawm 1.5% al-Qhov nyiaj seem uas tsis muaj kev sib txuam ua kom zoo.
Rau cov stathermakers ua kom tau raws li cov qauv nruj ua nruj (zoo li API 5L lossis tsheb silicon tsis yog ib qho kev xaiv {{2 {2 2}} Changer. Nws hloov "zoo" hlau rau hauv "hlau loj", nrog tsawg dua qhov tsis xws luag thiab muaj kev ua tau zoo ib yam.
