Sezvo calcium ine hukama hwakasimba neokisijeni, sulfuri, hydrogen, nitrogen uye kabhoni musimbi yakanyungudutswa, silicon-calcium alloys inonyanya kushandiswa deoxidation, degassing uye kugadzirisa sarufa musimbi yakanyungudutswa.Calcium silicon inogadzira yakasimba exothermic mhedzisiro kana yawedzerwa kusimbi yakanyungudutswa.Calcium inoshanduka kuita karusiyamu mhute musimbi yakanyungudutswa, ine simba rinonyandura pasimbi yakanyungudutswa uye inobatsira pakuyangarara kwezvinhu zvisiri zvesimbi.
