Nrog rau txoj kev loj hlob ntawm niaj hnub science thiab technology, steel kev lag luam raws li "skeleton" ntawm lub ntiaj teb no kev lag luam, nws txoj hauj lwm yog ua ntau thiab tseem ceeb, thiab cov steel zoo yuav tsum nruj dua, uas yog ib tug ntawm cov zoo txoj kev los txhim kho cov khoom. zoo ntawm steel carburization desulfurization, seamless calcium Seamless Solid Calcium Cored Hlau nyob rau hauv uas plays lub luag hauj lwm tseem ceeb heev.
Calcium Silicon Alloy yog binary alloy ntawm silicon thiab calcium, nws cov khoom tseem ceeb yog silicon thiab calcium, tab sis kuj muaj ntau cov hlau, txhuas, carbon, sulfur thiab phosphorus thiab lwm yam hlau. Vim muaj kev sib raug zoo ntawm calcium thiab oxygen, sulfur, hydrogen, nitrogen thiab carbon nyob rau hauv cov kua hlau, Calcium Silicon Alloy yog tsuas yog siv rau deoxidation, degassing thiab kho sulfur nyob rau hauv cov kua hlau, calcium silicon tom qab ntxiv cov kua hlau ua ib tug muaj zog exothermic nyhuv, calcium ua calcium vapor nyob rau hauv cov kua hlau, nplawm cov nyhuv ntawm cov kua hlau, uas yog conducive rau lub floating ntawm non-metallic inclusions. Tom qab deoxidation, silicon calcium alloy tsim cov khoom tsis yog xim hlau nrog cov khoom loj thiab yooj yim rau ntab, thiab tseem hloov cov duab thiab cov khoom ntawm cov khoom tsis yog hlau. Yog li ntawd, silicon calcium 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.
