He mea hoʻohui i hoʻohana ʻia no ka loaʻa ʻana o ka hao ductile me ka graphite spherical. Hoʻohui ʻia ia me kekahi mau metala a i ʻole nā ​​​​mea hoʻohui a hoʻohui ʻia i ka hao i hoʻoheheʻe ʻia e hāpai i ka crystallization o ka graphite i kahi ʻano spherical.

I. Ka wehewehe a me ke kumu o ka Spheroidizing Agent

ʻO ka mea hoʻoheheʻe spheroidizing kekahi metala a i ʻole nā ​​​​mea hoʻohui i hoʻohui ʻia i ka hao hoʻoheheʻe e loaʻa ai ka hao ductile me ka graphite spherical. ʻO kāna kumu nui ka hoʻololi ʻana i ka morphology graphite i ka hao hao mai ka flake a spherical, a laila e hoʻonui ai i nā waiwai mechanical, paʻakikī a me ka plasticity o ka hao. Hoʻokumu ʻia ka graphite spherical i ka hao ductile ma hope o ka mālama ʻana i ka spheroidization. ʻO kēia ʻano o ka graphite e ʻoi aku ka ʻoi aku o ka ikaika o ka hao ma mua o ka hao hina, a ʻoi aku ka ʻoi aku o kona paʻakikī ma mua o ka hao malleable, ʻoiai e mālama mau ana i nā pono o ka hao hina.

II. ʻO nā mea nui o nā mea hana Spheroidizing

ʻO nā mea nui o nā mea spheroidizing nā mea spheroidizing e like me ka magnesium, rare earth, silicon, calcium, barium, a me ka hao. Ma waena o lākou, ʻo ka magnesium ka mea maʻamau i hoʻohana ʻia i ka spheroidizing element ma muli o kona mana spheroidizing ikaika. He mea koʻikoʻi nō hoʻi nā mea o ka honua rare i ke kaʻina hana spheroidizing, no ka mea hiki iā lākou ke hoʻonui i ka hopena spheroidizing, hoʻemi i ka manaʻo o ka hao keʻokeʻo, a hoʻomaikaʻi i ka wai a me ka maʻemaʻe o ka hao. Hoʻohana nui ʻia ʻo Silicon e hoʻoponopono i ka haku mele o ka hao i hoʻoheheʻe ʻia a hoʻolaha i ke kaʻina hana graphitization.

III. Nā ʻano o nā mea hana Spheroidizing

Hiki ke hoʻokaʻawale ʻia nā mea hana spheroidizing i nā ʻano like ʻole e like me ka ferrosilicon rare earth magnesium spheroidizing agent, calcium silicide spheroidizing agent, rare earth alloy spheroidizing agent, calcium silicoaluminate spheroidizing agent, aluminum titanium alloy spheroidizing agent, a me nickel magnesium spheroidizing agent, etc.

Silicon-iron-rare earth-magnesium spheroidizing agent: He ʻano maʻamau kēia o ka spheroidizing agent ma Kina, ka mea nui i haku ʻia me ka silicon-iron, calcium, magnesium, rare earth, etc., i hoʻoheheʻe ʻia a hui ʻia. Hiki i kēia spheroidizing agent ke deoxidize a me ka desulfurize i ka wā o ke kaʻina hoʻoheheʻe kila, a hoʻomaikaʻi nui hoʻi i ka wai o ka hao i hoʻoheheʻe ʻia.

Silicon-calcium alloy spheroidizing agent: Hana nui ʻia mai ka silicon a me ka calcium, hiki iā ia ke spheroidize ferrite i loko o nā ʻano spherical i ka wā o ke kaʻina hoʻoheheʻe kila, hoʻomaikaʻi i ka maikaʻi o nā ferroalloys a hōʻemi i ka hoʻohana ʻana i ka ikehu a me nā kumukūʻai.

Rare earth alloy spheroidizing agent: He mea hoʻoheheʻe spheroidizing kiʻekiʻe kēia, me ka lanthanum oxide, gadolinium oxide, cerium oxide, praseodymium oxide, a me nā mea'ē aʻe.

IV. ʻO nā hiʻohiʻona a me nā pono o nā Agen Spheroidizing

Ka ikaika spheroidizing hiki: Magnesium, rare earth a me nā mea ʻē aʻe i loko o ka spheroidizing agent he mana spheroidizing ikaika, hiki ke hoʻololi i ka morphology graphite i ka hao hao mai ka flake a spherical.

ʻOi aku ka maikaʻi o ka hana: Spheroidized cast iron i ʻoi aku ka ikaika, ka paʻakikī a me ka plasticity, me nā waiwai mechanical i hoʻonui nui ʻia.

Hoʻonui i ka wai: Hiki i kekahi mau mea o ka spheroidizing agent ke hoʻomaikaʻi i ka wai o ka hao i hoʻoheheʻe ʻia, e hōʻemi ana i nā hemahema e like me ka slag a me nā ʻōpū i ka wā o ka hoʻolei ʻana.

Hoʻemi ʻia ka hoʻohana ʻana i ka ikehu a me ke kumukūʻai: Hiki i ka hoʻohana ʻana i nā mea spheroidizing ke hoʻonui i ka maikaʻi o ka hoʻolei ʻana a me ka maikaʻi, ʻoiai e hōʻemi ana i ka hoʻohana ʻana i ka ikehu a me nā koina hana.

V. Nā Kahua Hoʻohana o nā Mea Hoʻohui Spheroidizing

Hoʻohana nui ʻia nā mea hana spheroidizing i ka ʻoihana kila, ʻoi aku ka nui o ka hana ʻana i nā kaʻa, nā kaʻaahi, a me nā moku. ʻO ka hoʻohui ʻana i kahi mea liʻiliʻi o ka spheroidizing agent i ka wā o ka hoʻolei ʻana e hiki ke hoʻomaikaʻi nui i ka hana o ka hao. Eia kekahi, hoʻohana ʻia nā mea spheroidizing i ka hana ʻana o nā alumini alumini a me nā huahana uila, e hōʻemi i ka ʻili o ka ʻili o nā metala wai, hoʻomaikaʻi i ka wai, hoʻomaikaʻi i ka maikaʻi o ka ʻili o nā castings, a hoʻomaikaʻi i ka microstructure a me ka hana o nā alloys.

VI. ʻO ka mālama ʻana no ka hoʻohana ʻana i nā Agen Spheroidizing

ʻO ke kaʻina hānai kūpono: I ka hoʻohana ʻana i nā mea hana spheroidizing, pono e hahai i ke kaʻina hānai kūpono e hōʻoia i ko lākou pono a me ka palekana.

Ke koho ʻana i nā mea maka: E koho i nā mea waiwai kiʻekiʻe e like me ka honua rare, magnesium, silicon, a me ka hao, a e hōʻoia i ka maʻemaʻe a me ka paʻa o nā mea maka.

Ka palekana o ka hana: No ka mea, ʻo nā mea e like me ka magnesium i hoʻohana ʻia no ka spheroidization he lapalapa a pahū, pono ka mālama pono ʻana i nā lula palekana i ka wā o ka hana e hōʻoia i ka palekana o nā limahana a me nā mea hana.

ʻOi aku ma mua o 18 mau makahiki o ka ʻike o Vigor ma nā hana hao ductile. Inā he nīnau a koi kāu no ka hoʻomohala ʻana i nā huahana a hoʻomaikaʻi paha i kāu kaulahao lako, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou ma info@castings-forging.com
