Ferro Barium Silicon (abbreviated li FeBaSi) yog ib qho tshwj xeeb sib xyaw ferroalloy, feem ntau muaj 4-12% barium (Ba), 40-60% silicon (Si), thiab hlau (Fe) raws li qhov sib npaug. Tsis zoo li ib qho -element additives (piv txwv li,ferro silicon, ferro barium) lossis binary alloys (piv txwv li,ferro calcium silicon), nws cov silicon tshwj xeeb-barium synergy muab peb qhov txiaj ntsig tsis zoo ntawm cov khoom siv hlau: kev sib sib zog nqus deoxidation sai dua, kev ua kom zoo desulfurization, thiab kev hloov pauv ntawm cov duab sib txuas ntawm cov teeb meem cuam tshuam. Qhov no ua rau nws tsis muaj peev xwm tsim tau qis- pa oxygen, qis- cov hlau sulfur (xws li, daim ntawv tsheb hlau, cov kav dej hlau) thiab siab- zoo cam khwb cia hlau, daws qhov mob cov ntsiab lus ntawm "tsis tiav deoxidation" thiab "nrawm inclusion-induced defects" hauv cov txheej txheem ib txwm muaj.

Rau barium silicon inoculants, peb cov ntsiab lus hauv qab no yuav tsum tau hais txog:

Muaj zog tiv thaiv fading:Barium tso cai rau cov nyhuv inoculation kom ntev (feem ntau 10-15 feeb ntev dua li cov ferrosilicon inoculants zoo tib yam), ua rau nws zoo tagnrho rau cov castings loj lossis tos lub sijhawm thaum cov kab ntau lawm.

Tshem tawm ntawm cov hlau cam khwb cia dawb:Tseem ceeb txo cov hardness ntawm casting npoo, txhim kho machinability.

Uniform graphite morphology:Ua hom A graphite faib ntau yam, ua kom lub zog tensile ntawm cam khwb cia hlau.

Kev tswj hwm impurity yog qhov tseem ceeb: Al Tsawg dua los yog sib npaug li 2.0% zam nkim AlN suav nrog, thaum S Tsawg dua los yog sib npaug rau 0.05% tiv thaiv "re-sulfurization" ntawm cov hlau molten.

Core Advantages vs. Traditional Metallurgical Additives

FeBaSi outperforms ib leeg / binary additives nyob rau hauv qhov tseem ceeb metallurgical metrics, ncaj qha txo qhov tsis xws luag thiab nqi:

Cov kev siv tseem ceeb yog raws li nram no

Raws li ib qho inoculant, BaSi alloy yog tsim rau grey cam khwb cia hlau thiab ductile hlau, thiab muaj peev xwm txhawb kev tsim ntawm "A" hom graphite ua tiav graphite nodules.

Bariumsilicon alloy muaj peev xwm nucleate nyob rau hauv ntau qhov kub thiab txias, muaj zog spheroidization muaj peev xwm thiab kev lag luam kev lag luam, thiab tuaj yeem tiv thaiv qhov kev nyiam ntawm castings los ua dawb.

Thaum ferrobariumsilicon alloy muaj 10% -35% barium yog siv los ua deoxidizer hauv steelmaking, nws muaj kev siv siab thiab muaj peev xwm desulfurization, uas zoo dua li silicon-calcium alloy.

FAQ

Q: Dab tsi yog qhov txawv ntawm barium silicon inoculant thiab calcium silicon inoculant?

A: Barium silicon inoculant muaj zog tiv thaiv fading, tshwj xeeb tshaj yog thaum ua cov loj -section castings, qhov twg barium yog deb tshaj calcium.

Q: Yuav ua li cas cov khoom no yuav tsum tau khaws cia los tiv thaiv pulverization?

A: Nws yuav tsum tau muab cia rau hauv qhov chaw qhuav, zoo - qhov cua, tsis txhob ya raws, vim tias ya raws tuaj yeem ua rau oxidation thiab txawm pulverization ntawm alloy nto.
