Alloy Cored Hlau

Ntshiab calcium hlau (hlau calcium khoom core coated hlau) khoom core ntshiab calcium core hlau tau siv nyob rau hauv kev kho mob ntawm molten hlau los ntawm txawv teb chaws Steel Mills nyob rau hauv 1970s, thiab tau dav siv nyob rau hauv lub ntiaj teb no mus txog rau tam sim no. , tshwj xeeb tshaj yog nyob rau hauv 1990s, nrog rau kev loj hlob sai ntawm nyias slab nruam casting tshuab, qhov zoo ntawm cov khoom calcium core hlau tau raug lees paub los ntawm feem ntau zoo-paub Steel Mills. Tam sim no, kev lag luam sib koom ntawm cov khoom siv calcium core hlau tau tshaj 70 hauv North America thiab 40 hauv Europe. Nyob rau hauv xyoo tas los no, ntau lub tuam txhab steel hauv Suav teb tau xa cov khoom calcium core hlau, thiab tau txais txiaj ntsig zoo ntawm kev lag luam thiab kev sib raug zoo. Qhov hnyav ntawm CA feem pua ​​​​calcium tub ntxhais hlau g / M calcium core hlau hauv cov qauv calcium core hlau: qhov hnyav ntawm steel sawb yog 97.01.0 Ntau dua lossis sib npaug rau 67.0 Ntau dua lossis sib npaug rau 3: 7, nws cov qauv kev qhia thiab kev ua haujlwm yog raws li hauv qab no: cov khoom tseem ceeb ntshiab calcium cored hlau tsim thiab kev ua haujlwm 1 siv tus kheej- ua 7.5-7.8 hli ntshiab calcium hlau ua cov khoom tseem ceeb ntawm cored hlau. 2 txias- dov ci steel sawb yog siv los npog cov calcium core hlau, uas yog thicker dua calcium hlau core hlau. Txoj kab uas hla ntawm cov khoom tseem ceeb ntshiab calcium core hlau yog 1.9.5 0.5 hli. Lub 3- tub ntxhais hlau muaj qhov zoo ntawm cov kab hlau tsis sib xws, lub zog tensile siab, zoo toughness thiab tsis yooj yim rau tawg, uas yog qhov zoo dua rau kev tswj xyuas cov xaim pub mis. 4 tuaj yeem siv rau qib steel kho los ntawm SI-CA cored hlau thiab Ca-fe cored hlau, thiab cov txiaj ntsig ntawm ca tuaj yeem nce ntau dua 52 feem pua. Siv cov xaim uas twb muaj lawm-cov khoom siv pub mis, qhov tob tob ntawm cov hlau molten tuaj yeem pom tau nyob rau hauv qis xaim- pub ceev, cov hlau- pub kom muaj nuj nqis yog yooj yim los tswj kom raug thiab cov hlau{{ 34}} txheej txheem pub mis yog ruaj khov. C6 core yog compact thiab nruj nreem qhwv, cia nws khaws cia rau lub sij hawm ntev thiab siv tau zoo. Cov txiaj ntsig tseem ceeb, cov txiaj ntsig ntawm calcium nyob rau hauv qis -carbon thiab qis- silicon steel, sawv cev los ntawm SPHC, yog tshaj 15 feem pua ​​​​ntawm qhov nruab nrab, thiab kev siv cov calcium yog li 52 feem pua ​​​​siab dua li ntawm silicon-calcium cored hlau. 2. Kev txuag nqi yog qhov tseem ceeb. Kev pub mis hnyav ntawm ton steel khoom core ntshiab calcium cored hlau tsuas yog kwv yees li 38 feem pua ​​​​ntawm silicon-calcium cored hlau. 3 yog qhov tsim nyog rau kev tsim cov hlau ntshiab. Txo thiab tshem tawm nozzle clogging ntawm nruam casting hlau. 5 txo qhov kev siv zog ua haujlwm.
