10-50mm Calcium Silicon Alloy Lump
Cov ntaub ntawv tseem ceeb:
Ib tug binary alloy muaj xws li silicon thiab calcium, teej tug mus rau qeb ntawm ferroalloy.Nws cov khoom tseem ceeb yog silicon thiab calcium, thiab nws kuj muaj impurities xws li hlau, txhuas, carbon, sulfur thiab phosphorus nyob rau hauv ntau yam.Siv hauv kev lag luam hlau thiab hlau ua calcium additive, deoxidizer, desulfurizer thiab denaturant ntawm non-metallic inclusions.Kev lag luam cam khwb cia hlau siv ua inoculant thiab denaturant.

Daim ntawv thov:
Vim hais tias calcium thiab kua hlau nyob rau hauv cov pa oxygen, sulfur, hydrogen, nitrogen thiab carbon muaj ib tug muaj zog affinity, yog li silicon calcium alloy yog tsuas yog siv rau cov kua steel deoxidation, degassing thiab tsau sulfur.Cov nyhuv exothermic ntawm si-ca ntxiv rau molten steel yog muaj zog.Calcium hloov mus rau hauv calcium vapor hauv cov kua hlau, uas muaj cov nyhuv ua rau cov kua hlau thiab muaj txiaj ntsig zoo rau cov ntab ntawm cov nonmetallic inclusions.Tom qab deoxidation, non-metallic inclusions nrog cov khoom loj dua thiab yooj yim rau ntab yuav raug tsim, thiab cov duab thiab cov khoom ntawm non-metallic inclusions yuav raug hloov.Yog li ntawd, si-Ca alloy yog siv los tsim cov hlau huv, cov hlau zoo uas tsis tshua muaj oxygen thiab cov ntsiab lus sulfur, thiab cov hlau tshwj xeeb uas tsis tshua muaj oxygen thiab cov ntsiab lus sulfur.Ntxiv cov calcium silicon alloy tuaj yeem tshem tawm raws li qhov kawg deoxidizer hauv txhuas hlau hauv lub ladle nozzle nodules, thiab nruam nruam hlau |ironmaking ntawm tundish nozzle clogging thiab lwm yam.Nyob rau hauv cov txheej txheem ntawm tawm ntawm lub cub tawg refining ntawm hlau, cov ntsiab lus ntawm oxygen thiab sulfur nyob rau hauv steel yog txo mus rau ib tug tsawg theem los ntawm deoxidizing thiab desulphurizing nrog calcium silicate hmoov los yog core hlau.Nws tseem tuaj yeem tswj tau daim ntawv sulfide hauv cov hlau thiab txhim kho kev siv cov calcium.Hauv kev tsim cov hlau cam khwb cia, si-Ca alloy tsis tsuas yog ua lub luag haujlwm ntawm deoxidation thiab purification, tab sis kuj plays lub luag hauj lwm ntawm inoculation, uas pab tsim cov nplua los yog kheej kheej graphite.Lub graphite tis nyob rau hauv grey cam khwb cia hlau yog uniform thiab nyiam ntawm whiteness yog txo.Thiab tuaj yeem nce silicon, desulfurization, txhim kho qhov zoo ntawm cam khwb cia hlau.

FAQ:
Q: Koj puas yog tuam txhab lag luam lossis chaw tsim khoom?
A: Peb yog Hoobkas.
Q: Koj lub sijhawm xa khoom ntev npaum li cas?
A: Feem ntau nws yog 5-10 hnub yog tias cov khoom muaj nyob hauv Tshuag.los yog nws yog 15-20 hnub yog tias cov khoom tsis nyob hauv Tshuag, nws yog raws li kom muaj nuj nqis.
Q: Koj puas muab cov qauv?puas yog dawb los yog ntxiv?
A: Yog lawm, peb tuaj yeem muab cov qauv dawb tab sis tsis them tus nqi thauj khoom.
Q: Koj cov nqe lus them nqi yog dab tsi?
A: Them nyiaj<= 1000USD, 100% ua ntej.Kev them nyiaj>= 1000USD, 30% T / T ua ntej, tshuav nyiaj li cas ua ntej xa khoom.
