Yuav ua li cas xaiv cov yeeb nkab zoo stainless hlau fittings (xws li stainless hlau luj tshib) - qhov sib txawv ntawm nruab nrab zaus rauv thiab refining rauv

2024-04-07 IB

Cov lus piav qhia: Cov kab lus no yog txhawm rau pab cov neeg siv khoom kawm thiab sib txawv ntawm cov kav hlau stainless uas tsim los ntawm qhov nruab nrab zaus rauv taws thiab cov kav hlau tsis muaj steel uas ua los ntawm cov tshuab ua kom zoo dua qub, kom lawv tuaj yeem xaiv cov yeeb nkab zoo zoo stainless hlau fittings (xws li stainless hlau luj tshib).

Tam sim no, cov kav hlau tsis muaj steel nyob rau hauv kev ua lag luam feem ntau muab faib ua refining furnace ntau lawm thiab nruab nrab zaus furnace ntau lawm, yog li dab tsi yog qhov txawv ntawm ob?

1. Cov txheej txheem ntau lawm

Thaum refining stainless hlau kav, lub refining rauv yuav tshuab pa oxygen, inert gases argon (Ar) thiab nitrogen (N2) rau hauv cov hlau molten kom ua tiav lub tshuab nqus tsev vacuum, uas yuav txo tau cov pa roj carbon ntsiab lus nyob rau hauv stainless hlau kav mus rau theem qis heev. . , thiab tshuab nyob rau hauv inert gas tib lub sij hawm kuj yuav inhibit lub oxidation ntawm chromium alloy ntsiab nyob rau hauv stainless hlau.

Lub tshuab hluav taws xob nruab nrab ntawm lub tshuab hluav taws xob tsim hluav taws xob sib nqus los ntawm kev hloov tam sim no kom sov cov hlau hauv qhov cub rau steelmaking. Thaum siv lub tshuab hluav taws xob nruab nrab los tsim cov kav hlau tsis muaj steel, cov ntsiab lus carbon tsis tuaj yeem raug txo qis thiab cov impurities tsis tuaj yeem raug tshem tawm.

2: Cov yam ntxwv ua haujlwm sib txawv

Cov kav hlau stainless uas tsim los ntawm lub qhov cub refining muaj cov ntsiab lus carbon tsawg thiab ob peb impurities, thiab tuaj yeem khaws cov khoom siv zoo xws li chromium. Yog li ntawd, cov kav hlau stainless uas tsim los ntawm lub qhov cub refining muaj cov ductility siab thiab tuaj yeem ua tiav kev ua haujlwm zoo xws li khoov, khoov, nthuav dav, shrinking, thiab lwm yam, kom tau raws li cov kev xav tau ntawm stainless hlau yeeb nkab fittings, thiab vim tias lawv cov impurities tsawg. , lawv tuaj yeem ua kom tiav qhov kev thov siab ntawm qhov chaw polishing ntawm stainless hlau yeeb nkab fittings (xws li stainless hlau luj tshib).

Stainless hlau kav ua los ntawm nruab nrab-frequency furnaces muaj cov ductility tsis zoo thiab kev ua haujlwm tsis zoo hauv kev khoov, khoov, nthuav dav, thiab shrinking. Cov ntsiab lus impurity nyob rau hauv stainless hlau kav yog siab, thiab lawv tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua kom zoo polishing ntawm cov khoom zoo stainless hlau yeeb nkab fittings (xws li stainless hlau luj tshib).

Peb: cov khoom sib txawv

Lub qhov cub refining tuaj yeem ua cov steelmaking theem nrab, thiab feem ntau tuaj yeem hloov kho ntxiv lossis txo cov ntsiab lus tseem ceeb kom ua tiav lub hom phiaj ntawm kev ua kom zoo, yog li cov hlau thiab hlau xuab zeb feem ntau yog siv los ua cov khoom siv raw. cov

Lub tshuab hluav taws xob nruab nrab tsuas tuaj yeem ua cov hlau ib zaug xwb, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv raw, uas tsis tuaj yeem tswj tau yooj yim, yog li stainless hlau seem thiab hlau xuab zeb feem ntau yog siv rau smelting. Txoj kev smelting no tsis tuaj yeem tswj cov ntsiab lus ntawm qee cov ntsiab lus, yog li cov khoom lag luam zoo kuj tsis zoo thiab feem ntau tsis siv rau hauv cov khoom lag luam xws li kev sib sib zog nqus.

Zhejiang Mingli Yeeb Nkab Kev Lag Luam yog Tuam Tshoj stainless hlau yeeb nkab fittings Hoobkas nrog ntau tshaj 30 xyoo ntawm kev tsim khoom thiab kev ua haujlwm. Cov ntaub ntawv raw yog 100% refined furnace steel kav, kom ntseeg tau qhov zoo ntawm qhov chaw.

1. Qhov chaw nruab nrab ntawm ob qhov kawg yog qhov sib txawv

Lub hauv paus ntsiab lus ntawm ob qhov kawg ntawm stainless hlau eccentric reducer tsis nyob rau tib axis.

Cov ntsiab lus nruab nrab ntawm ob qhov kawg ntawm stainless hlau concentric reducer yog nyob rau tib axis.

2. Qhov chaw ua haujlwm sib txawv

Ib sab ntawm stainless hlau eccentric reducer yog tiaj. Qhov kev tsim no ua kom yooj yim tso pa tawm los yog kua dej thiab ua kom yooj yim txij nkawm. Yog li ntawd, nws feem ntau yog siv rau kab rov tav cov kav dej.

Lub hauv paus ntawm stainless hlau concentric reducer yog nyob rau ntawm ib txoj kab, uas yog qhov tsim nyog rau cov kua dej ntws thiab tsis muaj kev cuam tshuam nrog cov qauv ntws ntawm cov kua dej thaum lub sij hawm txoj kab uas hla. Yog li ntawd, nws yog feem ntau siv rau txoj kab uas hla txo cov roj los yog ntsug cov kav dej.

3. Cov txheej txheem installation sib txawv

Stainless hlau eccentric reducers yog tus cwj pwm los ntawm cov qauv yooj yim, kev tsim khoom yooj yim thiab siv tau, thiab tuaj yeem ua tau raws li ntau yam kev xav tau ntawm cov kav dej. Nws daim ntawv thov scenarios feem ntau suav nrog:

Kab rov tav cov yeeb nkab kev sib txuas: Txij li cov ntsiab lus nruab nrab ntawm ob qhov kawg ntawm stainless hlau eccentric reducer tsis nyob rau tib kab kab rov tav, nws tsim nyog rau kev sib txuas ntawm cov kav dej kab rov tav, tshwj xeeb tshaj yog thaum cov yeeb nkab txoj kab uas hla yuav tsum tau hloov.

Pump inlet thiab regulating valve installation: Sab saum toj ca installation thiab hauv qab ca installation ntawm stainless hlau eccentric reducer yog tsim rau lub installation ntawm lub twj tso kua mis inlet thiab regulating valve feem, uas yog zoo rau tso tawm thiab tawm.

Stainless hlau concentric reducers yog tus cwj pwm los ntawm kev cuam tshuam tsawg dua rau cov kua dej ntws thiab tsim nyog rau txo txoj kab nruab nrab ntawm cov pa roj los yog cov kav dej ntsug. Nws daim ntawv thov scenarios feem ntau suav nrog:

Gas los yog ntsug kua pipeline kev twb kev txuas: Txij li thaum lub nruab nrab ntawm ob kawg ntawm stainless hlau concentric reducer yog nyob rau tib axis, nws yog tsim nyog rau kev sib txuas ntawm cov roj los yog ntsug kua kav, tshwj xeeb tshaj yog nyob rau hauv lub cheeb yuav tsum tau txo.

Xyuas kom muaj kev ruaj ntseg ntawm cov dej ntws: Cov stainless hlau concentric reducer muaj kev cuam tshuam me ntsis nrog cov kua dej ntws tawm thaum lub sij hawm txoj kab uas hla txo thiab tuaj yeem ua kom ruaj khov ntawm cov dej ntws.

4. Kev xaiv ntawm eccentric reducers thiab concentric reducers nyob rau hauv daim ntawv thov

Hauv kev siv tiag tiag, cov reducers tsim nyog yuav tsum raug xaiv raws li cov xwm txheej tshwj xeeb thiab cov kev xav tau ntawm cov kav dej sib txuas. Yog tias koj xav tau txuas cov kav dej kab rov tav thiab hloov cov yeeb nkab txoj kab uas hla, xaiv stainless hlau eccentric reducers; Yog tias koj xav tau txuas cov kav dej los yog cov kav dej ntsug thiab hloov txoj kab uas hla, xaiv stainless hlau concentric reducers.
