Calcium silicon alloyyog cov khoom sib xyaw ua ke ntawm cov khoom silicon, calcium thiab hlau. Nws yog dav siv nyob rau hauv zus tau tej cov hlau zoo, uas tsis muaj carbon steel, stainless hlau thiab lwm yam steels thiab tshwj xeeb alloys xws li nickel-based alloys thiab titanium-based alloys. calcium silicon alloy yog ib qho zoo tagnrhocomposite deoxidizerthiab desulfurizer. Nws cov qauv tshuaj yog CaSi. Nws muaj kev sib raug zoo ntawm calcium thiab oxygen. Hauv particular, calcium tsis tsuas yog muaj zog affinity nrog oxygen, tab sis kuj muaj zog affinity nrog sulfur thiab nitrogen. Qhov no ua rau calcium silicon alloy kom zoo tshem tawm impurities xws li oxygen thiab sulfur thaum lub sij hawm steelmaking txheej txheem, txhim kho kev ua tau zoo ntawm steel, thiab txhim kho cov yas, cuam tshuam toughness thiab fluidity ntawm hlau. Tsis tas li ntawd, calcium silicon alloy kuj tseem siv tau los ua cov inoculant rau cam khwb cia hlau thiab ib qho ntxiv hauv kev tsim cov hlau ductile, uas ua lub luag haujlwm tseem ceeb hauv kev txhim kho qhov zoo thiab kev ua haujlwm ntawm cam khwb cia hlau. cov
Kev tsim cov calcium silicon alloy pib xyoo 1907 thiab tau tsim los ntawm cov txheej txheem hluav taws xob silicon thermal. Nyob rau hauv cov txheej txheem ntau lawm, cov tshuaj tiv thaiv yog tswj, xws li nce qhov kub ntawm cov tshuaj tiv thaiv cheeb tsam nyob rau hauv lub cub tawg (kwv yees li 2000 degree los yog saum toj no), thiab ntxiv silica los rhuav tshem cov carbides seem nyob rau hauv qab ntawm lub cub tawg kom inhibit qhov nce. qhov cub hauv qab thiab tsim cov phab ntsa ntawm lub cub tawg, uas yog qhov tsim nyog rau kev tsim cov hlau. Hauv cov txheej txheem ntawm kev tsim cov calcium silicon alloy, ntau cov khoom siv raw, xws li silica, txiv qaub, coke, thiab lwm yam, tau noj, thiab qee qhov ntawm slag raug tsim. Txawm li cas los xij, qhov kev rov zoo siab ntawm calcium thiab silicon tuaj yeem ua tiav los ntawm cov txheej txheem tsim khoom tsim nyog thiab kev ua haujlwm.
Cov tshuaj muaj pes tsawg leeg ntawm calcium silicon alloy feem ntau muaj Ca Ntau dua lossis sib npaug li 24% -28% thiab Si txog 60%, thiab cov ntsiab lus tshwj xeeb txawv raws li cov qauv tsim thiab siv sib txawv. Piv txwv li, cov tshuaj muaj pes tsawg leeg ntawm calcium silicon alloy hauv YB / T5051 tus qauv suav nrog ntau qhov tshwj xeeb xws liCa31 Si 60, Ca28 Si 60thiab Ca24Si60 kom tau raws li cov kev xav tau ntawm cov qib steel sib txawv thiab cov alloys tshwj xeeb. Kev tsim cov calcium silicon alloy tsis yog tsuas yog muaj txiaj ntsig zoo rau kev lag luam metallurgical, tab sis kuj tseem ua lub luag haujlwm hloov tsis tau hauv kev txhim kho cov khoom zoo thiab kev ua haujlwm ntawm cov khoom hlau.
