ʻO ke kaʻina hoʻomalu maikaʻi o nā paipu hao malleable

ʻO ka mea mua, nā kumu nui e pili ana i ka hopena lapaʻau

ʻO nā ʻāpana paipu Mary e pili ana i ka nui kūpono ma muli o ke ʻano o kona ʻano metamorphism pono e haiki loa, a no laila ʻoi aku ka paʻakikī o ka hoʻopaʻa ʻana ma mua o ka hao ductile.Pono kēia i nā kumu kaʻina pili e hoʻoikaika e hana i ka volatility liʻiliʻi.ʻO ka hopena lapaʻau o nā paipu hao malleable ʻoi aku ka nui o ke kaʻina hana ʻo ia ka nui o nā ʻano.

1, ka sulfur maʻiʻo o ka metala wela kumu

Ka emi ʻana o ka hoʻohana ʻana i ka sulfur.He ikaika loa ia o ka sulfur metala wela a me ka magnesium kiʻekiʻe, cerium, calcium, ʻoi aku ka nui o nā modifier i vulcanized i loko o ka slag, a laila e hōʻemi ana i ka hiki ke kumu i ka deterioration o ka mālama pono ʻole.No laila, i ka hana 'ana o ka malleable hao paipu pono e ho'āʻo e hoʻohana haʻahaʻa sulfur-loaʻa puaʻa hao a me ka coke.ʻO nā kūlana, e hana i nā hana mua no ka desulphurization he mea pono.ʻAʻole kēia e ʻōlelo ʻia me ka ʻoi aku ka nui o ka sulfur maʻiʻo o ka hao i hoʻoheheʻe ʻia ʻaʻole hiki ke hana maikaʻi ʻia i nā mea hoʻopili hao malleable.Nui nā hale hana kūloko a me nā ʻāina ʻē me ka sulfur maʻiʻo a hiki i ka 0.06-0.08% o ka cupola metala wela hiki ke hana paʻa i nā mea hoʻopili hao hao malleable, akā ʻoi aku ka maikaʻi o ka hoʻohana.ʻIke e pili ana i nā ʻike me 0.07-0.13% sulfur wela metala hana o compacted graphite hoʻolei i ka hao ma lalo o kekahi mau kūlana, e like me ka titanium e hoʻonui i ke ʻano o ka hana mai ka hoʻohana ʻana i ka hopena anti-ball o ka sulfur.Eia nō naʻe, ʻo ka nui o ka sulfur ka hana paʻa i nā mea pono e pono ai.

2, ka mahana hana o ka hao hehee

Ke hooheheeia ka ha'aha'a wela lapa'au 'o Gao i mea nui i ka absorption rate o ka alloy, oi aku ka magnesium-based vermicularizing oi aku.ʻO ke kiʻekiʻe o ka mahana, ʻoi aku ka ikaika o ka hoʻolapalapa ʻana i ka magnesium gasification, ʻoi aku ka liʻiliʻi o kekahi, ʻoi aku ka haʻahaʻa e like me ka hiki ke hana pū ka mahana.Hōʻike ka palapala i ka hoʻohana ʻana i ka magnesium titanium composite modifier i ka hoʻoponopono ʻana i nā paipu hao malleable, nā hopena o ka wela lapaʻau like ʻole i ka pono o ka mālama ʻana.Ke hana nei ma 1400 ℃, ka graphite e like me ka ilo i ʻoi aku ma mua o 95%, ʻaʻole ka pōleʻa;ma 1280 ℃ lapaʻau, ʻoi aku ma mua o ka hapalua o nā nodules graphite.ʻO ka nui o Alloy ka like, ka mahana hana o ka nui o ka absorption ʻike ʻia.

I ka hana maoli, pono e noʻonoʻo ʻia ka mahana e hoʻoholo ai i ke kaʻina hana no ka hoʻolei ʻana i nā koi wela.Eia nō naʻe, pono e paʻa ka mahana o ka hoʻoili ʻana, inā nui ka fluctuation o ka mahana, pono e hoʻoponopono ʻia ka nui o ka alloy, inā ʻaʻole paʻakikī ke hōʻoia i ka maikaʻi o ka mālama ʻana.

ʻO ka vermicularizing ma ka honua kakaʻikahi, ʻoi aku ka kiʻekiʻe o ka mahana o ka hana ʻana.

3. Hana hana

Mai ke kaʻina kolo o ke kaʻina hana ma muli o ka fluctuations i ka pane tangled koʻikoʻi, no laila e koi ana i ka hana e aʻo i ka pololei loa.ʻO ke kūlike o ka hui ʻana o ka alloy, ka uhi uhi ʻana i ka hihia, ka nui a me ka hao hao, slag slag a me nā ana ʻē aʻe, e like me ka hopena pololei i ka hopena lapaʻau.
