Intangiriro yo gutangiza:Inoculantsni ubwoko bumwe bushobora guteza imbere igishushanyo mbonera, kugabanya imyumvire yumunwa wera, kunoza morphologie no gukwirakwiza grafite, kongera umubare witsinda rya eutectic, gutunganya imiterere ya matrix.
Uduce duto twa Ferrosilicon (inoculant idasanzwe yo gukina)
Ferrosiliconibice ferrosilicon inoculant, ikoreshwa mu gukora ibyuma, gukora ibyuma,castinginoculant.
Ibiranga ferrosilicon inoculant:
(1) Ibigize uduce twa ferrosilicon ni kimwe kandi gutandukanya ni bito;
(2) ingano ya ferrosilicon ni imwe, nta fu nziza, kandi ingaruka zo gutera zirahagaze;
.
(4) kuramba kuramba no kugabanya ubuso bwubuso;
.
(6) kurandura microshrinkage igaragara no kunoza imikorere ya casting.
Silica-barium (calcium) inoculant
Silica-barium inoculant, (BA-SI)ni isiliconifu nifu ya barium mukuvanga ukurikije igipimo cyibisabwa, hanyuma hanyuma ukoresheje itanura ryubushyuhe bwo hejuru bwo gukora ibyuma mubikoresho byinshi byuma. umunwa, kunoza morphologie no gukwirakwiza grafite, kongera umubare wamatsinda ya eutectic, no gutunganya imiterere ya matrix.
Silica-bariumimikorere idahwitse:
1.
2. Irashobora kugabanya neza urugero rwa supercooling yicyuma gishongeshejwe, igateza imbere imvura ya grafite, igabanya cyane imyunvire yumunwa wera, kugabanya ubukana ugereranije, no kunoza imikorere yo gutunganya.
3. Ubushobozi bukomeye bwo kurwanya ihungabana, igihe cyo kurwanya ihungabana ni inshuro 2 za75 silicon, ingano ya silicon bariuminoculantni munsi ya kimwe cya kabiri cya 75 ferrosilicon inoculant, mugihe irinda ihungabana rya spheroidification.
4, uburebure bwurukuta ni buto, kunoza igice kimwe, kugabanya imyumvire yo kugabanuka no kwidegembya.
5, imiti yimiti irahamye, gutunganya granularité ni kimwe, ibihimbano no gutandukana kwiza ni bito.
6. Gushonga ni bike (munsi ya 1300 °), kandi biroroshye kubyakira no gushonga mugihe utera, kandi ibibyimba ni bike cyane.
