Hoʻokaʻawale ʻana i ka hao puaʻa maka no ka uwea hao hao

Me ka hoʻomohala ʻana o ka ʻoihana mining, ua nui loa ka hoʻohālikelike ʻana i ka hao puaʻa i ko mākou ʻāina, e hoʻokō i nā pono o ka ʻoihana mīkini.ʻO ka ʻōlelo maʻamau, hana ka hale hana uea haouwea hao haoHiki ke hoʻokaʻawale ʻia ka hao i ʻelua mau ʻāpana, pololei mai ka hao hao ma o ka hoʻomaʻamaʻa ʻana i ka hao ma waho o ka metala, ʻo nā mea nui o ka ʻaila ʻo ia ka iron oxide, silica a me nā pōhaku like ʻole.Ke hoʻomaʻemaʻe kūikawāʻia kēiaʻano i ka hao hao, ua hui pūʻia nā mea e like me carbon, silicon, manganese a pēlā aku, i kapaʻia kaʻikepili i hoʻomaʻemaʻeʻia - e like me ka hao puaʻa maʻamau, no ka papa mua o ka mea.

E like me nā koi like ʻole o ka ʻoihana, hoʻokomo ʻia nā paona like ʻole o nā ingots i loko o ka umu hoʻoheheʻe e like me ka maʻamau, e like me ka ulana, Ming, pepa, lang, silicon, etc. hao hao.ʻO ka hao he hao hina, hao keʻokeʻo a me ke gula i ʻōlelo ʻia ma luna, he mau ʻano like ʻole ko lākou, no laila i ka ʻoihana e like me kā lākou mau ʻano like ʻole e lawe a koho.No ka laʻana, i ka hao hina, aia kona kalapona i loko o ka hao hao ma ke ʻano graphite, ʻeleʻele pinepine ka māwae, palupalu a ikaika, kānana maʻalahi, kūpono no ka hoʻolei ʻana.
I ka hao keʻokeʻo, ʻo kona kalapona a me ka hao i hui pū ʻia i ka hao carbide, ʻike ʻia ka māwae keʻokeʻo, ikaika loa a palupalu ka maikaʻi, no ke kila malleable.Loaʻa i ka papa alloy nā mea hoʻohui like ʻole me nā haku mele a me nā hale like ʻole.No ka mea hiki i nā mea hoʻohuihui i loko o ka hao hao ke hana i ke keleawe ma o ka pae mānoanoa o ka hoʻoikaika ʻana, ka paʻakikī, ka ikaika o ka hopena, ke kūpaʻa ikaika, ka palena pani, ka elongation, no laila ka hoʻohui ʻana i ka hao i ka hana o ka hao kiʻekiʻe, ʻo ia ka mea hoʻohui mua.

ʻO nā kumu nui e hoʻoulu ai i ka ʻeleʻele metala: ka haʻahaʻa pili o ka lewa ma ka mahana like, ka pākēneka o ka maʻi o ka mahu wai a me ka ʻike o ka mahuka wai i ka lewa, i ʻike ʻia ʻo ka humidity pili.Ma lalo o kekahi haʻahaʻa pili, he liʻiliʻi loa ka corrosion rate o ka ʻaila antirust metala, akā ʻoi aku ka kiʻekiʻe ma mua o ka haʻahaʻa pili, piʻi koke ka corrosion rate.Kapa ʻia kēia haʻahaʻa haʻahaʻa pili i ka haʻahaʻa koʻikoʻi.Ke kiʻekiʻe ka haʻahaʻa o ka lewa ma mua o ka haʻahaʻa koʻikoʻi, e ʻike ʻia ka ʻili metala i kahi kiʻiʻoniʻoni wai a i ʻole nā ​​​​wai kulu wai, inā loaʻa i ka lewa nā mea haumia ʻino, hoʻoheheʻe ʻia i loko o ke kiʻi wai, nā kulu wai, nā electrolytes a me ka corrosion aggravate.
