Muaj nuj nqi thiab cov khoom ntawm Silicon Calcium Cored hlau

Tshuaj Muaj Tshuaj

Cov tub ntxhais ntawm Sica cored hlau feem ntau muaj:

Calcium (Ca): 28-35% (thawj cov haujlwm nquag rau kev deoxidation thiab xam nrog kev hloov kho)

Silicon (si): 55-65% (txhim kho fluhonity thiab ua raws li deoxidizer)

Aluminium (Al): Tsawg dua lossis sib npaug nrog 1.5% (cov ntsiab lus me (cov ncauj lus me los pab hauv Deagidation)

Cov pa roj carbon (c), Sulfur (s), phosphorus (p): txo qis kom tsis txhob impurities

Tus Hlau Sheath tiv thaiv cov alloy los ntawm kev ua ntej oxidation, ua kom muaj kev nqus cov nqi siab (feem ntau 15-30%).

Cov Khoom Siv Lub Cev

Txoj kab uas hla: Ntau qhov ntau thiab tsawg ntawm 9 hli mus rau 16 hli (tus qauv: 13 hli) {3} {3}

Hlau ntev: Feem ntau 3, 000}}} {mm per coil {} 4}}

Ceev & filling piv: Txoj kev sib piv: Txoj kev sib piv yog ~ 200-300 g / m, ua kom zoo nkauj li koob tshuaj .

Cov Kev Xaiv Txheej Txheem: Cov tshuaj tiv thaiv xeb lossis cov kev kho mob tshwj xeeb tuaj yeem thov rau kev tso tseg cia khoom ruaj khov.

Desulfurization & Deagidation

Calcium reacts nrog cov leej faj thiab oxygen (O) los ua ib tug neeg ua ib zaug thiab cao, txo kev phom sij .

Ntau dua ntau dua li kev sib tw suav ntxiv vim yog tob nkag rau hauv Molten Steel .

Hais txog kev hloov kho

Hloov dua siab, muaj kev txwv tsis pub muaj (e {{} g}}

Txo cov nozzle clogging hauv nruam casting .

Alloying & Composition tswj

Kho kom haum ca thiab SI cov ntsiab lus kom tau raws li cov qauv steel tshwj xeeb (e {} cov hlau roj carlesss, stainless hlau).

Txhim kho kev ua pov hwm thiab txo cov pa porosity .

Txhim Kho Cov Hlau Huv Thiab Cov Neeg Kho Tshuab

Txo cov hydrogen-inducts cracking (hic) thiab sulfide kev ntxhov siab tawg (SSC) hauv cov hlau pipeline {}}

Txhim kho kev cai tawv thiab tshuabsab .
