Dab tsi yog cov khoom zoo ntawm cov hlau seamless calcium hlau?
1. Muaj calcium rov qab tus nqi
Piv nrog cov hlau cored, cov hlau ruaj khov muaj zog dua, qhov ntom ntom zoo dua thiab cov ntsiab lus calcium ntau dua, uas tuaj yeem pub calcium rau qhov tob ntawm cov hlau molten thiab nyob hauv qab qhov tob qhov tseem ceeb rau lub sijhawm ntev, yog li ua tiav cov calcium rov qab ntau dua. Hauv kev siv tiag tiag, tus nqi rov qab ntawm cov khoom calcium hlau yog siab dua li ntawm cov hlau cored, thiab cov hlau tsis muaj calcium hlau yog siab dua li ntawm seamed hlau. Ib lub Hoobkas hauv tsev siv 1.5 hli seamless hlau calcium hlau, thiab cov nqi rov qab ntawm SPHC steel qib yog ruaj khov ntawm ntau dua 38%.
2. ruaj khov calcium nce hauv molten steel
Cov khoom siv tseem ceeb ntawm calcium hlau hlau thiab silicon calcium hlau yog calcium hmoov, uas yog cov khoom siv tsis sib xws thiab hollowness. Cov khoom siv tseem ceeb ntawm cov khoom siv calcium uas ntshiab hlau yog cov khoom siv high-density ntshiab calcium core pas nrig, uas muaj ntau dua, zoo ib yam thiab ruaj khov calcium cov ntsiab lus nyob rau hauv ib chav tsev ntev, kom ntseeg tau tias muaj zog calcium kev kho mob nyhuv.
3. Ntau qhov tsim nyog rau cov hlau ntshiab huv
Khoom ntshiab calcium xaim yog lub siab zoo nkauj calcium core paus dos, qhov yooj yim me me txheem lub neej tshwj xeeb, thiab tuaj yeem txo cov calcium oxide inclusions uas ua phem rau cov hlau molten kom tsawg; Cov txheej txheem ntawm cov khoom siv calcium hlau calcium uas tsis muaj cov txheej txheem kev kho mob yuav tsis coj mus rau lwm cov oxides uas muaj nyob rau hauv cov hmoov cored hlau los ua paug cov hlau molten (piv txwv li: hlau oxide nyob rau hauv calcium hlau hlau), thiab cov khoom ntshiab calcium hlau tuaj yeem txo qhov kev noj ntawm calcium ib tuj ntawm steel thiab txo cov pa phem ntawm molten steel piv rau cov tsoos hmoov ntim cored hlau.
4. Txo qhov kev siv zog ntawm kev ua haujlwm thiab ua kom cov khoom zoo
Calcium hlau hlau thiab silicon calcium hlau tau sau rau hauv cov ntawv hmoov, thiab muaj ntau cov ntaub ntawv tsis sib xws thiab qhov tshwm sim hollow. Cov txheej txheem pub hlau feem ntau tawg thiab kaw cov hlau, uas muaj qee yam cuam tshuam rau steelmaking ntau lawm. Khoom ntshiab calcium xaim yog lub siab-ceev cov khoom ntshiab calcium qws qhwv hauv lub plhaub hlau tuab. Cov hlau yog ib qho nyuaj, tsis plam los yog sib txawv thaum lub sij hawm xaim noj, thiab kev ua haujlwm zoo heev. Tsis tas li ntawd, tib lub kauj ntawm cov khoom ntshiab calcium hlau yog kwv yees li 1 zaug ntev dua li ntawm cov calcium hlau hlau, thiab cov nyiaj siv tsawg dua. Tus naj npawb ntawm cov furnaces siv rau ib kauj ruam ntawm cov khoom ntshiab calcium hlau yog 4 npaug ntawm calcium hlau hlau. Yog li ntawd, kev siv cov khoom siv calcium hlau tsis yog tsuas yog ua rau cov xaim pub mis ua haujlwm zoo heev, tab sis kuj txo cov sij hawm threading zoo heev, thiab txo qis kev ua haujlwm ntawm cov neeg ua haujlwm.
