Silicon calcium kuj tseem hu ua silicon calcium alloy, yog ib hom hlau alloy uas muaj cov calcium uas silicon, hlau kuj yog cov khoom tseem ceeb, feem ntau siv hauv kev lag luam steel, vim qhov no yog ib qho zoo heev desulfurization, deoxidizer, cov nyhuv zoo heev, yog li kev siv tus nqi tau dhau los ua siab heev, feem ntau, nws muaj ntau heev hauv kev tsim cov hlau tsis tshua muaj carbon steel thiab stainless hlau. Thiab haum rau bof steel kev cob qhia rhiav siv ua cua sov tus neeg saib xyuas; Nws kuj tseem siv tau los ua inoculant ntawm cam khwb cia hlau thiab additive ntawm nodular cam khwb cia hlau ntau lawm.
Ob qho calcium thiab silicon muaj kev sib raug zoo rau cov pa oxygen. Calcium, tshwj xeeb, muaj kev sib raug zoo tsis yog rau oxygen xwb, tab sis kuj rau leej faj thiab nitrogen. Yog li si-Ca alloy yog ib qho zoo tagnrho compound gelling tus neeg saib xyuas thiab desulfurizer. Silicon alloy tsis tsuas yog muaj peev xwm deoxidation muaj zog, cov khoom deoxidation yog yooj yim rau ntab, yooj yim rau paug, tab sis kuj tuaj yeem txhim kho kev ua haujlwm ntawm cov hlau, txhim kho cov yas, cuam tshuam toughness thiab fluidity ntawm hlau. Tam sim no silicon - calcium alloy tuaj yeem hloov aluminium rau qhov kawg deoxidation.
(1) Si-Ca alloy yog ib qho zoo tagnrho deoxidizer. Ob leeg calcium thiab silicon desulfurizers muaj zog affinity rau oxygen. Calcium, tshwj xeeb, muaj kev sib raug zoo tsis yog rau oxygen xwb, tab sis kuj rau leej faj thiab nitrogen. Silicon alloy tsis tsuas yog muaj zog deoxidation muaj peev xwm, deoxidation cov khoom yog yooj yim rau ntab, yooj yim rau paug.
(2) Si-Ca alloy kuj tseem siv tau los ua inoculant ntawm cam khwb cia hlau thiab additive nyob rau hauv nodular cam khwb cia hlau ntau lawm.
(3) Silicon calcium alloy tuaj yeem deoxidized tsis yog txhuas, vim nws tuaj yeem tsis tsuas yog deoxidize tab sis kuj hloov kev ua tau zoo ntawm cov hlau, suav nrog cov toughness, plasticity thiab fluidity ntawm hlau, yog cov khoom siv deoxidizing zoo tshaj plaws. Nws kuj tseem tuaj yeem siv los ua cov khoom siv cua sov hauv qee qhov chaw, yog li nws tsis xav tsis thoob tias si-Ca alloys tam sim no tau siv dav, vim tias lawv cov teebmeem tuaj yeem ua tiav lub xeev xav tau.
