Hana o Nodularizing Agent a me Nodularizing Elements ma Ductile Iron Production
Alakaʻi maʻiʻo: ʻOiai he nui nā ʻano nodulizers ma ka home a ma waho, hoʻohana nui ʻia nā alloy magnesium honua i kēia manawa ma ko mākou ʻāina. I kēia manawa ke kūkākūkā nui nei mākou i ke kuleana o kēia ʻano o ka alloy a me kāna mau mea nodulizer.
ʻO ke kuleana o nā mea spheroidizing
ʻO nā mea i kapa ʻia ʻo spheroidizing element e pili ana i kēlā mau mea hiki ke hoʻoikaika i ka spheroidization o ka graphite, hana a hoʻonui paha i nā spheroids graphite. Loaʻa i nā mea hoʻoheheʻe spheroidized nā waiwai maʻamau penei: (1) Aia hoʻokahi a ʻelua paha electron valence ma ka pūpū electron waho o ka element, a he 8 electron ma ka ʻāpana lua o loko. ʻO kēia hoʻolālā uila e hana i ka mea i pili ikaika me ka sulfur, oxygen a me carbon, e hōʻike ana i ka paʻa o ka huahana a hiki ke hōʻemi nui i ka sulfur a me ka oxygen i loko o ka wai. (2) He haʻahaʻa ka solubility o nā mea i loko o ka hao i hoʻoheheʻe ʻia, a aia kahi manaʻo nui e hoʻokaʻawale i ka wā paʻa. (3) ʻOiai he pili kona me ke kalapona, haʻahaʻa kona solubility i ka lattice graphite. Wahi a nā hiʻohiʻona i luna, ʻo Mg, Ce, Y, a me Ca nā mea spheroidizing pono.
ʻO ka hoʻonohonoho ʻana o nā mea spheroidizing a me nā ʻano o nā mea hana spheroidizing
ʻIke ʻia ka magnesium, rare earth a me ka calcium i ka hiki ke hāpai i ka graphite spheroidization, akā pehea e hoʻomākaukau ai a hoʻohana iā lākou i hui pū ʻia me ka hana ʻoihana maoli, ʻaʻole wale ka hiki o ka spheroidizing o ka nodulizer, akā maʻalahi hoʻi ka hoʻomākaukau ʻana i ka hana, hoʻokele waiwai. nā mea maka, ua lilo ka maʻalahi o ka hoʻohana i ke kumu o ka hoʻokumu ʻana a me ka hoʻohana ʻana i nā nodulizers.
