He aha ke kila a pehea i hana ʻia ai?
Ke hoʻohui ʻia ka hao me ke kalapona a me nā mea ʻē aʻe, ua kapa ʻia ʻo ia he kila. ʻO ka hopena o ka alloy he mau noi e like me ka mea nui o nā hale, nā mea hana, nā mea hana, nā moku, nā kaʻa, nā mīkini, nā mea hana like ʻole, a me nā mea kaua. He nui nā mea hoʻohana ma muli o ka ikaika tensile kiʻekiʻe a me ke kumu kūʻai haʻahaʻa.
ʻO wai ka mea i ʻike?
Ua ʻike ʻia nā hiʻohiʻona mua loa o ke kila ma Turkey a hiki i ka makahiki 1800BC. ʻO ka hana hou o ke kila i hoʻi mai iā Sir Henry Bessemer o ʻEnelani nāna i ʻike i ke ʻano o ka hana ʻana i ka nui a me ke kumu kūʻai haʻahaʻa.
ʻO Jindalai Steel Group ka mea hana nui a me ka mea kūʻai aku o ke kila kila kila / pepa / pā / ʻāʻī / paipu.
He aha ka ʻokoʻa ma waena o ka hao a me ke kila?
ʻO ka hao he mea kūlohelohe maoli i loaʻa ma ke ʻano i loko o ka hao hao. ʻOi aku ka ikaika o ke kila ma mua o ka hao, me ka ʻoi aku ka maikaʻi o ka ʻuʻuku a me nā waiwai hoʻoemi.
He aha nā waiwai o ke kila?
● He kiʻekiʻe ka ikaika o ke kila
● He malleable - hiki ke maʻalahi ke hana
● Paʻa - hiki i ke kila ke kū i nā ikaika o waho.
● Conductivity - maikaʻi ia i ka hoʻokele ʻana i ka wela a me ka uila, pono no nā mea kuke a me nā uwea.
● Luster – nani ke kila a me ke kala.
● Rust Resistance – hiki i ka hoʻohui ʻana o nā mea like ʻole i nā pākēneka like ʻole ke hāʻawi i ke kila ma ke ʻano o ke kila kila ʻo ia ke kūpaʻa kiʻekiʻe.
ʻO wai ka mea ikaika, Steel a i ʻole Titanium?
Ke hoʻohui ʻia me nā metala ʻē aʻe e like me ka alumini a i ʻole ka vanadium, ʻoi aku ka ikaika o ka titanium alloy ma mua o nā ʻano kila. Ma ke ʻano o ka ikaika nui, ʻoi aku ka maikaʻi o ka titanium alloys i ka haʻahaʻa haʻahaʻa a hiki i ka pae waena. Eia naʻe, ʻoi aku ka ikaika o ka pae kiʻekiʻe o ke kila kila ma mua o nā alloys titanium.
He aha nā ʻano kila 4?
(1) ʻO ka hao hao
Loaʻa i nā kila kalapona ka hao, kalapona, a me nā mea hoʻohui like ʻole e like me Manganese, Silicon, a me Copper.
(2) Alloy Steel
Loaʻa i nā kila kila nā metala maʻamau i nā ʻāpana like ʻole, kahi e kūpono ai kēia ʻano kila no nā noi kikoʻī.
(3) Ke kila kila
ʻOiai ʻo nā kila kila he nui nā ʻāpana metala, loaʻa iā lākou ka 10-20% chromium, e lilo ia i mea hoʻohui mua. Ke hoʻohālikelike ʻia me nā ʻano kila ʻē aʻe, ʻoi aku ka nui o ke kūpaʻa ʻana o nā kila kila ma kahi o 200 mau manawa, ʻoi aku ka nui o nā ʻano i loaʻa ma kahi o 11% chromium.
(4) Mea hao hao
Hoʻopili ʻia kēia ʻano kila i nā wela kiʻekiʻe loa a loaʻa pinepine nā metala paʻakikī e like me tungsten, cobalt, molybdenum, a me vanadium. No ka mea ʻaʻole lākou he wela wale nō akā paʻa nō hoʻi, hoʻohana pinepine ʻia nā mea kila no ka ʻoki ʻana a me ka ʻeli ʻana.
He aha ka papa ikaika loa?
SUS 440– ʻo ia ka papa kiʻekiʻe o ke kila ʻokiʻoki a ʻoi aku ka nui o ke kalapona, ʻoi aku ka maikaʻi o ka paʻa ʻana i ka ʻaoʻao ke mālama pono ʻia. Hiki ke hoʻopaʻakikī ʻia e like me ka paʻakikī o Rockwell 58, e hoʻolilo iā ia i hoʻokahi o nā kila kila ʻoi loa.
No ke aha i kapa ʻole ʻia ai ke kila he metala?
ʻO kekahi o nā nīnau i nīnau pinepine ʻia e pili ana i ke kila no ke aha ʻaʻole i helu ʻia ke kila e like me ke metala? ʻO ke kila, ʻo ia ka mea hoʻohui a no laila ʻaʻole ia he mea maʻemaʻe, ʻaʻole ia he metala akā he ʻano hoʻololi i kekahi. He ʻāpana i haku ʻia me ka metala, hao, akā no ka loaʻa ʻana o ke kalapona metala ʻole i loko o kāna hana kemika, ʻaʻole ia he metala maʻemaʻe.
ʻO wai ke ʻano i hoʻohana nui ʻia?
ʻO 304 Stainless Steel a i ʻole SUS 304 ka papa maʻamau; ka 18/8 (18% chromium, 8% nickel) kila kila. Ma waho o ka US, ʻike ʻia ʻo ia ʻo "A2 stainless steel", e like me ISO 3506 (ʻaʻole e huikau me ke kila kila A2)
He mea hoomau anei ke kila?
He mea hoʻomau kūʻokoʻa ke kila no ka mea ke hana ʻia hiki ke hoʻohana ʻia, e like me ke kila, mau loa. Hoʻohana hou ʻia ke kila, no laila ʻaʻole e pau ka hoʻopukapuka ʻana i ka hana kila a hiki ke hoʻonui ʻia e nā hanauna e hiki mai ana.
ʻO kekahi mau mea hoihoi e pili ana i ke kila
● ʻOiai he mea ikaika loa ka hao, ʻoi aku ka ikaika o ke kila ma mua o 1000 manawa ma mua o ka hao.
● Hoʻolohi a paʻa paha ka ʻā ʻana o ke kila i ka wā e hele ana ke au uila ma ke kila. ʻIke ʻia kēia ʻo Cathodic Protection a hoʻohana ʻia no nā paipu, nā moku, a me ke kila i loko o ke kaʻa.
● ʻO ke kila ka mea i hana hou ʻia ma ʻAmelika ʻĀkau – kokoke i ka 69% o ka mea i hana hou ʻia i kēlā me kēia makahiki, ʻoi aku ia ma mua o ka plastic, pepa, aluminika, a me ke aniani i hui pū ʻia.
● Ua hoʻohana mua ʻia ke kila no nā skyscrapers i ka makahiki 1883.
● ʻOi aku ka nui ma mua o ka lāʻau o 40 lāʻau no ka hana ʻana i hale i kālai ʻia i ka lāʻau - hoʻohana ka hale i kālai ʻia i ke kila 8 mau kaʻa hana hou.
● Ua hana ʻia ka kaʻa kaʻa kila mua i ka makahiki 1918
● Hoʻohana hou ʻia nā kini kila 600 i kēlā me kēia kekona.
● 83,000 tons o ke kila i hoʻohana ʻia no ka hana ʻana i ke Alahaka Golden Gate.
● Ua ʻoki ʻia ka nui o ka ikehu e pono ai no ka hana ʻana i hoʻokahi tonne kila i ka hapalua i nā makahiki he 30 i hala.
● I ka makahiki 2018, he 1,808,6 miliona tone ka nui o ka hana kila crude honua. Ua like ia me ke kaumaha o kahi 180,249 Eiffel Towers.
● Ua puni paha ʻoe i ke kila i kēia manawa. ʻO kahi mea hana hale maʻamau he 65% o nā huahana kila.
● Aia ke kila i loko o kāu mea uila! ʻO nā mea a pau i hana i kahi kamepiula maʻamau, ma kahi o 25% o ia mea he kila.
ʻO Jindalai Steel Group- ka mea hana kaulana o ke kila galvanized ma Kina. Ke ʻike nei ma mua o 20 mau makahiki o ka hoʻomohala ʻana i nā mākeke honua a loaʻa iā ia nā hale hana 2 me ka mana hana ma luna o 400,000 tons i kēlā me kēia makahiki. Inā makemake ʻoe e ʻike hou aku e pili ana i nā mea kila, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou i kēia lā a i ʻole e noi i kahi ʻōlelo.
