Silicon barium alloy (Si Ba) o se tui sili ona lelei. O se u'amea u'amea e maualuga atu le gaioiga. Silicon barium Inoculants e fa'aoga ile u'amea fa'aefuefu, u'amea fa'ameamea, u'amea u'amea ma le u'amea vermicular. O le Ba, Ca ma isi elemene kemikolo i totonu e mautu. Pe a faatusatusa i le graphitization gafatia o ferro silicon, e mafai ona faaleleia le mafiafia eseese o le fausaga vaega ma le maaa uniformity faapea foi le faateleina o le numera o vaega eutectic ma pa'u o le saoasaoa e telegese. Faʻateleina le aofaʻi tutusa, o le barium silicon inoculation e mafai ona faʻaleleia atili ai le malosi tensile maualuga 20-30N / mm2 nai lo ferro silicon. Fa'atusatusa i le ferro silicon, pe a suia le aofaʻi o faʻaopoopoga, e laʻititi le faʻaogaina o le maaa. A maeʻa le togafitiga Spheroidizing o le uʻamea uʻamea faʻaopoopo le barium silicon lea e le gata e mafai ona faʻateleina le numera o le polo graphite ma faʻaleleia le taamilosaga ae faʻaumatia foi le sima ma faʻasalalau pe faʻaitiitia le phosphorus eutectic.
Talosaga:
1. Mo oxidation ma suiga o le uamea, lafo uʻamea ma alloys.
2. O lo'o i ai se gaioiga fa'a-dephosphorizing.
3. Fa'aitiitia le pa'epa'e o le u'amea
4. Faʻaleleia le mautu o le calcium i le uamea uʻamea, faʻaitiitia le faʻafefe o le calcium.
