1. Muaj cov core rods high-density hauv cov tub ntxhais hlau, thiab qhov tshwj xeeb ntawm qhov chaw ntawm cov tub ntxhais rods yog me me, uas tuaj yeem txo cov calcium oxide inclusions uas tsis ua haujlwm vim oxidation thiab ua paug rau cov hlau.
2. Cov ntsiab lus calcium ntau dua ib lub 'meter', siab dua thiab ruaj khov cov ntsiab lus calcium ntau dua, cov txiaj ntsig kho calcium ruaj khov.
3. Thick steel cladding (mm) thiab high density ntshiab calcium mandrel tuaj yeem pub calcium ntxaum rau hauv cov hlau molten thiab nyob ntev dua hauv qhov tob tob, yog li ua tiav cov calcium rov qab ntau dua.
4. High-density ntshiab calcium mandrels nrog ib qho yooj yim-rau-sim zoo, me me qhov chaw ntawm cov tub ntxhais, thiab lub neej txee ntev dua.
5. Khoom hnyav hnyav yog 1/2 ntawm calcium hlau. Siv cov kab ntshiab calcium rod kab tuaj yeem txo cov nqi kho calcium rau tons ntawm hlau.
6. Muab piv nrog cov tsoos hmoov-filled core hlau, cov tub ntxhais hlau tuaj yeem txo cov calcium noj ib tuj ntawm cov hlau, txhim kho cov calcium rov qab, txo cov nqi kho calcium thiab txo cov pa phem.
Cov yam ntxwv ntawm cov tub ntxhais hlau
1. Nws yog qhov tsim nyog rau kev tswj hwm cov ntsiab lus ntawm oxidizable ntsiab lus thiab cov kab mob, ua kom cov alloy tawm los, txo cov nqi smelting, txo lub sij hawm smelting, thiab tswj cov muaj pes tsawg leeg.
2. Nws tuaj yeem ntxuav cov hlau thiab ib nrab hloov qhov xwm txheej thiab cov duab ntawm kev suav nrog, txhim kho cov hlau zoo thiab cov pwm casting.
3. Cov tub ntxhais hlau yog muab faib ua ob hom: sab hauv rub hom thiab sab nraud rub hom. Cov cuab yeej siv tshuab xav tau rau kev pub hlau yog qhov yooj yim thiab txhim khu kev qha, npog thaj tsam me me, tshwj xeeb tshaj yog cov hlua rub sab hauv yog tsim nyog siv rau hauv qhov chaw nqaim.
4. Cored hlau muab faib ua ob hom: sab hauv-rub hom thiab sab nraud-rub hom. Cov cuab yeej siv tshuab xav tau rau kev pub hlau yog qhov yooj yim, txhim khu kev qha thiab npog thaj tsam me me, tshwj xeeb tshaj yog cov hlua rub sab hauv yog tsim nyog siv rau hauv qhov chaw nqaim.
