Calcium Silicon Rau Spheroidal Graphite Hlau
Calcium silicon (CaSi) feem ntau yog siv rau hauv kev tsim cov spheroidal graphite hlau (SGI), tseem hu ua ductile hlau lossis nodular hlau. SGI yog ib hom cam khwb cia hlau uas muaj graphite nyob rau hauv daim ntawv ntawm kheej kheej nodules, uas imparts zoo heev zog, ductility, thiab cuam tshuam rau cov khoom.

Ntawm no yog li cas calcium silicon siv hauv kev tsim SGI:
- Nucleation thiab Graphitization: Calcium silicon ntxiv rau cov hlau molten thaum lub sij hawm tsim SGI los txhawb nucleation thiab graphitization.
- Nodule suav thiab Morphology: Qhov sib ntxiv ntawm calcium silicon pab tswj qhov loj, suav, thiab morphology ntawm graphite nodules hauv SGI. Nws cuam tshuam cov duab thiab kev faib tawm ntawm cov nodules, uas, nyob rau hauv lem, cuam tshuam rau txhua yam khoom ntawm cov castings.
- Graphite Growth Control: Calcium silicon cuam tshuam rau kev loj hlob ntawm graphite thaum lub sij hawm solidification, pab tiv thaiv kev tsim cov graphite yam tsis xav tau xws li flake graphite.
- Desulfurization: Calcium silicon pab tshem tawm cov sulfur los ntawm cov hlau molten, vim nws reacts nrog sulfur los ua calcium sulfide (CaS).
Kev sib ntxiv ntawm calcium silicon hauv kev tsim khoom ntawm SGI yuav tsum tau ua tib zoo tswj nws cov muaj pes tsawg leeg thiab tag nrho cov alloy muaj pes tsawg leeg. Qhov tshwj xeeb ntawm calcium silicon thiab nws cov kev sib cuam tshuam nrog lwm cov alloying ntsiab yog qhov tseem ceeb kom ua tiav qhov xav tau nodularity thiab txhua yam khoom ntawm SGI. Nws raug nquahu kom sab laj nrog cov kws tshaj lij cov ntaub ntawv lossis cov txheej txheem engineers los txiav txim siab txog kev siv thiab kev pom zoo rau calcium silicon hauv SGI ntau lawm.
