Ua ntej: Cov tub ntxhais hlau yog ib yam ntawm cov khoom siv hlau siv hauv steel refining, uas yog tsim los ntawm core hmoov txheej thiab wrapping daim tawv nqaij ua los ntawm sawb steel ntawv qhwv rau sab nrauv ntawm core hmoov txheej.
Thib ob: Thaum siv, cov hlau cored txuas txuas ntxiv mus rau hauv lub ladle los ntawm cov hlau feeder. Thaum lub cladding ntawm cov tub ntxhais hlau nkag mus rau hauv lub ladle yog melted, cov tub ntxhais hmoov txheej yog raug thiab los mus rau hauv ncaj qha kev sib cuag nrog cov hlau molten mus nqa tawm cov tshuaj tiv thaiv, thiab los ntawm lub kinetic nyhuv ntawm argon roj stirring, nws muaj peev xwm ua tau zoo. Lub hom phiaj ntawm deoxidation, desulphurisation, thiab tshem tawm cov inclusions, thiaj li los txhim kho qhov zoo thiab kev ua tau zoo ntawm cov hlau.
Thib peb: nws tuaj yeem pom, txhawm rau ua kom cov hlau cored ua kom huv huv cov hlau, yuav tsum ua tau raws li ob yam xwm txheej, raws li cov txheej txheem tseem ceeb ntawm cov khoom xyaw yuav tsum muaj peev xwm nkag rau hauv txhua lub ces kaum ntawm cov hlau; core hmoov txheej ntawm active cov khoom xyaw nrog ib tug loj txaus mus ntes cov pa oxygen thiab sulfur atoms ntawm lub peev xwm.
Plaub: calcium silica core hlau nyob rau hauv cov calcium yog cov khoom siv feem ntau siv cov hmoov nplej, txawm hais tias nws yog ib qho deoxidiser muaj zog, tab sis vim nws qhov sib txawv ntawm qhov sib txawv, qhov qis melting point, thiab yooj yim los tsim npuas ntawm qhov kub thiab txias, yog li qhov yooj yim. kev siv cov calcium hlau core hlau core hmoov txheej yuav tshwm sim cov tub ntxhais hlau tsuas yog xa mus rau lub qhov cub ua kom zoo nyob rau hauv qhov tshwm sim ntawm combustion, thiab cov tub ntxhais hlau rau hauv nruab nrab ntawm cov hlau molten hauv qab no, tsis tuaj yeem ua tiav qhov kev xav tau purification nyhuv! Txawm hais tias kev siv cov txheej txheem kub-resistant txheej thiab kev ntxig nrawm thiab lwm yam kev ntsuas, tsis tuaj yeem cuam tshuam tag nrho nws cov combustion, thiab cov core hmoov txheej nyob rau hauv cov xwm txheej no combustion tsis tuaj yeem ua tiav cov nyhuv purification nyob rau tib lub sijhawm, nws tseem yuav ua tau. ua rau kev pov tseg ntawm cov khoom siv calcium uas kim dua.
