Ua hoʻokumu ʻia ka hale hana Ductile Iron mai 2021
1. Hōʻike pōkole:
ʻO ka hao hoʻoheheʻe ʻia he mea hao ikaika kiʻekiʻe i kūkulu ʻia i nā makahiki 1950.ʻO kāna hana holoʻokoʻa kokoke i ke kila.Ma muli o kāna hana maikaʻi loa, ua hoʻohana maikaʻi ʻia e hoʻolei i kekahi mau ikaika paʻakikī a me ka koi nui ʻana i ka ikaika, paʻakikī, a me ke kūʻē ʻana.Ua hoʻomohala wikiwiki ʻia ka hao hoʻoheheʻe ʻia i mea hao hao lua wale nō i ka hao hina hina a hoʻohana nui ʻia.ʻO ka mea i kapa ʻia ʻo "substituting iron for steel" e pili ana i ka hao ductile.Loaʻa i ka ductile cast iron ka graphite ductile ma o ka spheroidization a me ka mālama inoculation e hoʻomaikaʻi maikaʻi i nā waiwai mechanical o ka hao, ʻoi aku ka paʻakikī a me ka paʻakikī, a laila e loaʻa ai ka ikaika kiʻekiʻe ma mua o ke kila kalapona.
2. Hana:
Ua aneane hoʻohana ʻia nā hoʻoheheʻe hao ductile i nā ʻoihana nui a pau, e koi ana i ka ikaika kiʻekiʻe, plasticity, toughness, wear resistance, thermal and mechanical shock resistance, high or low temperature resistance, corrosion resistance, and dimensional stability.I mea e hoʻokō ai i kēia mau hoʻololi i nā kūlana o ka hoʻohana ʻana, he nui nā māka ductile iron, e hāʻawi ana i kahi ākea o nā ʻano mechanical a me ke kino.
3.Material:QT450-10
4. Noi:
ʻO nā ʻāpana hao ductile no nā ʻāpana kaʻa lalo, e like me ka uhi hope no ka huila lawe, ke kola no ka wili track, ka bracket no ka mea palaualelo.
5. Hiki ke hana:500-550T / Mahina, laina hana automated.
6. Pono:
1) Ke hoʻohālikelike ʻia me ka hao hao, ʻoi aku ka maikaʻi o ka hao ductile i ka ikaika.ʻO ka ikaika tensile o ka hao ductile he 60k, aʻo ka ikaika tensile o ka hao hao he 31k wale nō.ʻO ka ikaika hoʻohua o ka ductile cast iron he 40k, ʻoiai ʻaʻole hōʻike ka hao i ka ikaika o ka hoʻoulu ʻana a me ka haki ʻana.ʻOi aku ka maikaʻi o ka lākiō o ka hao ductile ma mua o ka hao.Ua like ka ikaika o ka hao ductile me ke kila hoolei.
2) Ke hoʻohālikelike ʻia me ke kila hoʻoheheʻe ʻia, ʻoi aku ka nui o ka ikaika o ka Ductile cast iron, ma mua o ke kila.ʻO ke kumu kūʻai haʻahaʻa o ka spherical graphite cast iron e ʻoi aku ka kaulana o kēia mea, ʻoi aku ka kiʻekiʻe o ka hoʻoheheʻe ʻana, a ua hoʻemi ʻia ke kumukūʻai machining o ka spherical graphite cast iron.
3) No laila, ma hope o ka hoʻoili ʻia ʻana o nā ʻāpana o ka ductile cast iron e ka fertilizing annealing cycle, hiki i ke ʻano spherical i loko o ka ductile cast iron ke hoʻopau i ke ʻano pohā e maʻalahi ka hana ʻana o ka flake graphite i loko o ka hao.Ma ka microphotograph o ka hao ductile, ʻike ʻia ka pau ʻana o nā māwae ma hope o ka hiki ʻana i ka pōpō graphite.I loko o ka ʻoihana hao ductile, ua kapa ʻia kēia mau pōpō graphite "nā pani pani" no ko lākou hiki ke pale i ka haki.
