Calcium Silicon (CaSi) yog cov hlau uas muaj silicon (Si) thiab calcium (Ca), nrog rau cov ntsiab lus ntawm 30-35% calcium thiab 55-60% silicon. Calcium-silicon alloy muaj ntau yam kev siv tseem ceeb hauv steelmaking thiab casting.
silicon calcium lub ntsiab nta
1. Cov deoxidizer muaj txiaj ntsig zoo: Calcium silicon yog lub zog deoxidizer, feem ntau yog siv rau hauv cov txheej txheem steelmaking kom tshem tawm cov pa oxygen ntawm cov hlau thiab txhim kho cov purity ntawm hlau. Cov nyhuv deoxidizing ntawm calcium thiab silicon tuaj yeem txo cov pa oxygen ntawm cov hlau thiab txhim kho nws cov khoom siv dag zog thiab tawv.
2. Desulfurizer: Calcium muaj kev sib raug zoo rau leej faj, yog li calcium-silicon alloys tuaj yeem tshem tawm sulfide ntawm hlau, yog li txo cov sulfur cov ntsiab lus ntawm cov hlau thiab txhim kho cov yas thiab ductility ntawm hlau.
3. Txhim kho cov kev ua tau zoo ntawm cov hlau **: calcium silicate alloy tuaj yeem kho cov qauv ntawm cov hlau, txhim kho cov hnav tsis kam, corrosion kuj thiab lub zog ntawm cov hlau, feem ntau siv los ua cov hlau muaj zog thiab hnav-resistant steel.
4. Inoculant: Hauv kev tsim cov hlau cam khwb cia, calcium silicate tuaj yeem muab ntxiv ua cov inoculant, uas tuaj yeem txhim kho cov graphite morphology hauv cov castings, refine cov nplej, txo cov hardness thiab brittleness ntawm cov castings, thiab txhim khu lub toughness thiab machinability. cov castings.
5. Txo qhov nyiam ntawm porosity: Vim tias calcium thiab silicon tuaj yeem tsim cov oxides tsis txaus thiab nitrides nrog oxygen, nitrogen thiab lwm yam roj hauv cov hlau, calcium-silicon alloy tuaj yeem txo qhov tsim ntawm porosity thiab txhim kho qhov ntom ntawm cov hlau.
6. Kev ruaj ntseg siab: Calcium-silicon alloy muaj qhov zoo thermal stability ntawm qhov kub thiab txias thiab tsis-volatile, haum rau siv nyob rau hauv high-temperature steelmaking txheej txheem. Tsis tas li ntawd, nws tuaj yeem cuam tshuam cov oxidation ntawm hlau thiab txo cov kev suav nrog hauv cov hlau.
7. Yooj yim rau ntxiv thiab zoo dispersion: Calcium silicate alloy muaj qhov ntom ntom, yooj yim ntxiv rau cov hlau molten thiab sai thiab sib npaug, uas yuav pab kom ua tiav cov txiaj ntsig deoxidation thiab desulfurization.
Calcium silica alloy yog dav siv nyob rau hauv steelmaking, casting thiab lwm yam hlau ua industries, thiab yog tsim rau zus tau tej cov carbon steel, structural steel, stainless hlau thiab ib co high-kev ua tau zoo alloys.
