Incoulant BaCaSi- luv luv rau Barium-Calcium-Silicon inoculant- yog ib qho khoom siv siab tshaj plaws uas feem ntau siv hauv kev tsim thiab kev lag luam steelmaking. Thaum ib txwm silicon-raws li inoculants tsom rau graphite nucleation thiab txo qis, BaCaSi muaj kev sib koom ua ke ntawm peb lub ntsiab lus tseem ceeb: barium (Ba), calcium (Ca), thiab silicon (Si). Qhov kev sib xyaw ua ke no ua rau muaj txiaj ntsig zoo rau kev hloov kho ntawm cov khoom tsis yog -cov khoom siv hlau, ua kom zoo li - cov qauv cam khwb cia, thiab txhim kho cov khoom siv ntawm cov hlau cam khwb cia hlau thiab cov hlau tshwj xeeb.
Lub ntsiab kom zoo dua ntawm BaCaSi nyob rau hauv nws muaj zog deoxidizing thiab desulfurizing muaj peev xwm. Barium, ua hnyav dua thiab tsis hloov pauv ntau dua li calcium, ua kom lub sijhawm cov tshuaj tiv thaiv hauv cov hlau molten, tso cai rau kev nkag mus tob dua ntawm cov teebmeem inoculating. Qhov no ua rau muaj kev txo qis hauv kev ua kom txias thiab tsim cov carbide hauv nyias-walled castings. Meanwhile, calcium ua raws li ib tug muaj zog deoxidizer thiab sulfide zoo li tus maub los, hloov teeb meem elongated manganese sulfides mus rau hauv tsis muaj teeb meem globular los yog blocky sawv daws yuav, uas boosts tej toughness thiab machinability.
Hauv nodular cam khwb cia hlau ntau lawm, BaCaSi inoculants tsim cov nodule ntau dua thiab ntau dua graphite faib piv rau tus qauv FeSi lossis CaSi inoculants. Qhov tshwm sim yog txhim kho tensile lub zog, elongation, thiab txo shrinkage porosity. Rau cov hlau refining, BaCaSi pab ua kom tiav cov hlau huv los ntawm kev txhawb kev tsim cov qis- melting- taw tes calcium aluminates, uas ntab tawm yooj yim, thiab los ntawm kev txo cov reoxidation thaum nruam nruam.
Cov kev sim ua lag luam tau pom tias BaCaSi ua haujlwm zoo dua li cov pa inoculants nyob rau hauv fading resistance- qhov kev poob qis ntawm inoculation tshwm sim dhau sijhawm. Qhov no ua rau nws tshwj xeeb tshaj yog haum rau cov chaw tsim khoom loj nrog cov voj voog ntev dua los yog cov kab molding tshuab. Txawm li cas los xij, kev tswj hwm nruj ntawm Ba thiab Ca piv yog qhov tseem ceeb; barium ntau dhau yuav ua rau muaj teeb meem ferrite stabilization, thaum calcium ntau dhau tuaj yeem ua rau slag tsim.
Raws li kev lag luam thawb kom sib zog, muaj zog, thiab qaug zog ntau dua - cov khoom siv hlau tiv taus, incoulant BaCaSi sawv cev rau qhov kev vam meej hauv cov txheej txheem metallurgy. Nrog rau kev tshawb fawb tsis tu ncua mus rau nanoparticle- txhim kho cov qauv, nws tuaj yeem dhau los ua tus qauv zoo rau kev ua haujlwm siab - kev ua haujlwm casting thiab huv steel ntau lawm hauv kaum xyoo tom ntej.
