Ukusetyenziswa kweCalcium Metal kuShishino lokwenza iNsimbi
Isinyithi se-calcium sinesicelo esibalulekileyo kwishishini le-steelmaking, elinokuphucula ukusebenza kunye nomgangatho wensimbi.
1. I-Calcium yonyango ye-calcium: i-metallic calcium idla ngokusetyenziswa njenge-agent yonyango ye-calcium kwinkqubo yokwenza i-steelmaking.Ngokudibanisa inani elifanelekileyo le-calcium yensimbi kwisithando somlilo sensimbi, ukungcola kwe-oksijini njenge-oxides, i-sulfides kunye ne-nitrides kwintsimbi etyhidiweyo inokususwa ngokufanelekileyo, ngaloo ndlela iphucula ukucoceka kwensimbi etyhidiweyo.
2. I-Deoxidizer: Isinyithi seCalcium sinokusetyenziswa njenge-deoxidizer kwinkqubo yokwenza insimbi.Ngexesha lenkqubo yokunyibilikisa, ngokongeza i-metallic calcium kwintsimbi etyhidiweyo, i-calcium inokusabela ngeoksijini kwintsimbi etyhidiweyo ukuze ivelise i-calcium oxide, kwaye iphendule ngokungcola ekubunjweni kwayo ukwenza i-oxides, ukunciphisa ngokufanelekileyo umxholo we-oksijini enyibilikisiweyo kunye nokuphucula umphumo we-deoxidation yensimbi. .
3. Isilungisi: Isinyithi seCalcium sinokuphinda sisetyenziswe njenge-modifier yokuphucula i-crystal structure kunye neempawu zomatshini zetsimbi.Kwinkqubo yokwenza i-steelmaking, i-calcium ye-metallic inokusabela nge-silicon, i-aluminium kunye nezinye izinto kwintsimbi etyhidiweyo ukwenza i-carbides kunye ne-silicides efana ne-calcium oxide, ihlambulule iinqununu, kunye nokuphucula amandla kunye nokuqina kwentsimbi.
4. Izongezo ze-alloy: Isinyithi se-calcium sinokusetyenziswa njengezongezo ze-alloy kwintsimbi yokuphucula kunye nokulungelelanisa ukubunjwa kweekhemikhali kunye neempawu zensimbi.Ngokweemfuno, isixa esifanelekileyo se-calcium yesinyithi singongeza kwintsimbi ukulungelelanisa umxholo we-silicon, ukutshintsha ubushushu be-martensitic yentsimbi, kunye nokwandisa ubulukhuni.
Isinyithi se-calcium sidlala indima ebalulekileyo kwishishini le-steelmaking, ukuphucula umgangatho kunye neempawu zetsimbi.Ngokusetyenziswa kwe-calcium agents, i-deoxidizers, i-modifiers kunye ne-alloy additives, ubunyulu, i-deoxidation effect, i-crystal structure kunye ne-mechanical properties yensimbi inokuphuculwa ngokufanelekileyo ukuhlangabezana neemfuno zentsimbi kwiindawo ezahlukeneyo zesicelo.
