Silicon Barium

ʻO Silicon barium alloy (Si Ba) kahi inoculant kiʻekiʻe. He mea hao me ka hana kiʻekiʻe. Pili ka Silicon barium Inoculants i ka hao hina hina, hao nodular, hao ductile a me ka hao vermicular. ʻO ka Ba, Ca a me nā mea kemika i loko o ia mea paʻa. Ke hoʻohālikelike ʻia me ka mana graphitization o ka ferro silicon, hiki iā ia ke hoʻomaikaʻi i ka mānoanoa like ʻole o ka ʻāpana ʻāpana a me ka paʻakikī like ʻole me ka hoʻonui ʻana i ka helu o ka hui eutectic a me ka wikiwiki o ka recession. Ke hoʻonui nei i ka nui like, hiki i ka barium silicon inoculation ke hoʻomaikaʻi i ka ikaika tensile kiʻekiʻe 20-30N /mm2 ma mua o ferro silicon. E hoʻohālikelike i ka ferro silicon, i ka wā e loli ai ka nui o nā mea hoʻohui, liʻiliʻi ka laulā paʻakikī. Ma hope o ka mālama ʻana i ka Spheroidizing o ka hao i hoʻoheheʻe ʻia e hoʻohui i ka barium silicon ʻaʻole hiki ke hoʻonui i ka helu o ka pōpō graphite a hoʻomaikaʻi i ka pōʻai akā hoʻopau pū i ka cementite a hoʻopuehu a hōʻemi paha i ka phosphorus eutectic.

Noi:
1. No ka oxidation a me ka hoʻololi 'ana o ke kila, hoolei hao a me ka alloys.
2. Loaʻa i ka hana dephosphorizing.
3. E hoemi i ka keokeo o ka hao
4. Hoʻomaikaʻi i ka paʻa o ka calcium i ke kila hoʻoheheʻe ʻia, e hōʻemi ana i ka volatilization o ka calcium.
