Khoom Description
Calcium silicon cored hlau yog cov khoom siv hlau. Nws yog tsim los ntawm silicon-calcium alloy sab hauv thiab hlau hlau qhwv sab nraud. Lub luag haujlwm tseem ceeb ntawm Si-Ca alloy yog txo cov oxidation poob ntawm cov hlau yaj thiab txhim kho cov purity thiab yield ntawm hlau. Nws yog dav siv nyob rau hauv industrial teb, xws li steelmaking, casting thiab hlau thaum tshav kub kub kho.
Ua ntej, silicon-calcium cored hlau muaj kev ua haujlwm zoo ntawm deoxidation thiab desulfurization. Hauv cov txheej txheem hlau thiab hlau smelting, vim tias cov pa oxygen thiab sulfur yog cov khoom tsis zoo, lawv yuav cuam tshuam rau kev ua tau zoo thiab cov hlau zoo. Cov silicon thiab calcium ntsiab nyob rau hauv calcium silicon cored hlau tuaj yeem hnov mob nrog oxygen thiab sulfur kom tshem tawm lawv los ntawm cov hlau molten, yog li txhim kho cov purity thiab kev ua haujlwm ntawm cov hlau. Yog li ntawd, tus yam ntxwv no ua rau cov silicon-calcium cored hlau ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv smelting zoo hlau. Tsis tas li ntawd, ntxiv calcium silicon cored hlau nyob rau hauv hlau thiab hlau smelting txheej txheem kuj yuav txuag tau lub zog thiab tiv thaiv ib puag ncig. Piv nrog rau cov txheej txheem smelting ib txwm, cov calcium silicon cored hlau tuaj yeem txo lub zog noj thiab emissions hauv cov txheej txheem smelting thiab txo cov pa phem ib puag ncig. Nyob rau tib lub sijhawm, vim qhov ua tau zoo deoxidation thiab desulfurization kev ua tau zoo ntawm silicon-calcium cored hlau, nws tuaj yeem txo cov khoom siv pov tseg hauv cov txheej txheem smelting thiab txhim kho kev siv cov peev txheej. Yog li ntawd, daim ntawv thov ntawm calcium silicon cored hlau tsis yog tsuas yog pab txhim kho cov txiaj ntsig kev lag luam ntawm cov tuam txhab hlau thiab hlau, tab sis kuj tsim nyog rau kev txhawb nqa ntsuab thiab kev tsim kho kom ruaj khov.
Silicon-calcium cored hlau kuj tau siv dav hauv lwm qhov chaw. Piv txwv li, nyob rau hauv lub tshuab fais fab, calcium silicon cored xov hlau feem ntau yog siv los ua cov conductors, tshwj xeeb tshaj yog nyob rau hauv high-voltage transmissions thiab substations. Nws muaj cov yam ntxwv ntawm lub teeb yuag, muaj zog conductivity, siab dabtsi yog khoov lub zog thiab corrosion kuj, uas tuaj yeem ua kom ruaj khov kis tau tus mob tam sim no, txo cov kab poob thiab txhim kho kev ua haujlwm ntawm lub zog hluav taws xob.
