kev siv ntawm silicon calcium
1. Vim hais tias calcium muaj ib tug muaj zog affinity nrog oxygen, sulfur, hydrogen, nitrogen thiab carbon nyob rau hauv molten steel, silicon-calcium alloy yog tsuas yog siv rau deoxidation, degassing thiab tsau sulfur ntawm molten hlau.
2. Calcium silica ua rau muaj zog exothermic nyhuv thaum ntxiv rau molten hlau. Calcium hloov mus rau hauv calcium vapor nyob rau hauv molten steel, uas muaj ib tug stirring nyhuv ntawm molten steel, uas yog zoo rau lub floating ntawm non-metallic inclusions. Tom qab deoxidation ntawm silicon-calcium alloy, non-metallic inclusions nrog cov khoom loj thiab yooj yim rau ntab yog tsim.
3. Nyob rau tib lub sijhawm, cov duab thiab cov khoom ntawm cov khoom tsis yog xim hlau kuj raug hloov. Yog li ntawd, silicon-calcium alloy yog siv nyob rau hauv productionClean steel, high-zoo steel nrog tsawg oxygen thiab sulfur cov ntsiab lus, thiab tsis tshua muaj oxygen thiab sulfur cov ntsiab lus tshwj xeeb kev kawm steel.
