1.He aha ka Hot Rolled Steel Material Grades
ʻO ke kila he mea hao i loaʻa kahi wahi kalapona liʻiliʻi.Hele mai nā huahana kila ma nā māka like ʻole e pili ana i ka pākēneka o ke kalapona i loko o lākou.Hoʻokaʻawale ʻia nā papa kila like ʻole e like me kā lākou ʻano kalapona.Hoʻokaʻawale ʻia nā māka kila ʻōwili wela i nā hui kalapona:
Loaʻa i ke kalapona haʻahaʻa a i ʻole ke kila māmā he 0.3 % a i ʻole ka liʻiliʻi o ke kalapona ma ka leo.
Loaʻa i ka 0.3% a i ka 0.6% kalapona ke kila kalapona waena.
Loaʻa i nā kila kalapona kiʻekiʻe ma mua o 0.6% kalapona.
Hoʻohui pū ʻia nā mea liʻiliʻi o nā mea hoʻohui like ʻole e like me ka chromium, manganese a i ʻole tungsten e hana i nā māka kila he nui.Hāʻawi nā ʻokoʻa kila like ʻole i kekahi mau waiwai kūʻokoʻa e like me ka ikaika tensile, ductility, malleability, durability, a me ka thermal and electrical conductivity.
2. ʻOkoʻa ma waena o Hot Rolled Steel a Cold Rolled Steel
Hana ʻia ka hapa nui o nā huahana kila ma nā ʻano kumu ʻelua: ka ʻōwili wela a i ʻole ka ʻōwili anu.ʻO ke kila wili wela ke kaʻina wili e ʻōwili ʻia ai ke kila ma kahi wela kiʻekiʻe.ʻO ka maʻamau, ʻoi aku ka mahana o ke kila ʻōwili wela ma mua o 1700°F.ʻO ke kila ʻōwili anu he hana ia e kaomi ʻia ai ke kila ma ka mahana wela.
He mea nui ia e hoʻomaopopo ʻaʻole ʻo ke kila wela a me ke kila ʻōwili anu.ʻO ia nā ʻenehana hana mua i hoʻohana ʻia no nā ʻano huahana kila.
Hot Rolled Steel Process
ʻO ke kila ʻōwili wela e pili ana i ka hana ʻana a me ka ʻōwili ʻana i nā papa kila i loko o kahi kaula lōʻihi i ka wā e hoʻomehana ʻia ana ma luna o kona mahana ʻōwili maikaʻi loa.Hānai ʻia ka papa ʻulaʻula ma o nā wili ʻōwili e hana a hoʻohola i loko o kahi ʻāpana lahilahi.Ma hope o ka pau ʻana o ka hana ʻana, hoʻomaʻamaʻa ʻia ka ʻili kila i ka wai a ʻeha i loko o kahi wili.Hoʻoulu ʻia nā ʻano mea hoʻoheheʻe wai ʻē aʻe i loko o ke kila.
ʻO ka hoʻomaʻamaʻa ʻana i ke kila ʻōwili wela i ka lumi wela e hiki ai ke hoʻonui i ka ikaika a me ka ductility.
Hoʻohana maʻamau ʻia ke kila ʻōwili wela no ke kūkulu ʻana, nā ala kaʻaahi, ka ʻili metala, a me nā noi ʻē aʻe ʻaʻole makemake i nā hoʻopau nani a i ʻole nā ʻano kikoʻī a me nā hoʻomanawanui.
Ka Kaʻina kila i hoʻolili ʻia
Hoʻomaʻamaʻa ʻia ke kila ʻōwili anuanu e like me ke kila ʻōwili wela akā ua hana hou ʻia me ka hoʻohana ʻana i ka annealing a i ʻole ka ʻōwili wela e hoʻomohala i ka ikaika tensile kiʻekiʻe a me ka ikaika hoʻohua.ʻO ka hana hou a me ka manawa no ka hoʻoponopono ʻana e hoʻohui i ke kumukūʻai akā hiki i ka hoʻomanawanui ʻana o ka dimensional a hāʻawi i kahi ākea o nā koho hoʻopau.ʻOi aku ka maikaʻi o kēia ʻano kila a hoʻohana ʻia i nā noi e koi ana i kahi kūlana ili kūikawā a me ka hoʻomanawanui dimensional.
ʻO ka hoʻohana maʻamau no ke kila ʻōwili anuanu, ʻo ia nā ʻāpana hana, nā lako metala, nā mea pono hale, nā ʻāpana kaʻa a me nā noi ʻenehana kahi e pono ai ka pololei a i ʻole ka nani.
3.Hot Rolled Steel Grades
Loaʻa ke kila ʻōwili wela i nā papa he nui e hoʻokō i kāu mau kikoʻī papahana.Hoʻonohonoho ka American Society for Testing and Materials (ASTM) a i ʻole Society of Automotive Engineers (SAE) i nā maʻamau a me nā māka e like me ke ʻano kino a me nā hiki o kēlā me kēia metala.
Hoʻomaka nā māka kila ASTM me ka leka "A" e kū nei no nā metala ferrous.Hoʻohana ka ʻōnaehana helu SAE (ʻike ʻia ʻo American Iron and Steel Institute a i ʻole ʻōnaehana AISI) i ka helu ʻehā no ka hoʻohālikelike ʻana.Hoʻomaka nā māka kila kalapona maʻemaʻe i kēia ʻōnaehana me ka huahelu 10, a ukali ʻia e nā helu helu ʻelua e hōʻike ana i ka ʻike kalapona.
ʻO kēia nā māka maʻamau o ke kila ʻōwili wela.E ʻoluʻolu e hāʻawi ʻia kekahi mau huahana ma nā koho ʻōwili wela a me ke anuanu.
A36 ʻO ke kila kila wela
ʻO ke kila A36 i hoʻopaʻa ʻia ʻo ia kekahi o nā mea kila wela loa i loaʻa (hiki mai ia i kahi ʻano ʻōwili anuanu, ʻoi aku ka liʻiliʻi).Mālama kēia haʻahaʻa kalapona kila ma lalo o ka 0.3% carbon content ma ke kaumaha, 1.03% manganese, 0.28% silicon, 0.2% copper, 0.04% phosphorus, a me 0.05% sulfur.ʻO nā noi ʻoihana kila A36 maʻamau me:
Nā papa kaʻa
Mea mahiai
Pākuʻi
ʻO nā ala hele wāwae, nā ramps, a me nā ala kiaʻi
Kākoʻo kūkulu
Nā huakaʻi hele
Hana maʻamau
1018 ʻO ka pahu hao kalapona ʻōwili wela
Ma hope o A36, ʻo AISI/SAE 1018 kekahi o nā māka kila maʻamau.ʻO ka maʻamau, hoʻohana ʻia kēia māka ma mua o A36 no nā ʻano pahu a i ʻole nā pahu.1018 mea kila i hele mai i loko o ka wela owili a me ke anu, oiai ua oi maa mau o ke anu.ʻOi aku ka ikaika a me ka paʻakikī o nā mana ʻelua ma mua o A36 a ʻoi aku ka maikaʻi no nā hana hana anu, e like me ke kuʻi ʻana a i ʻole ka swaging.ʻO 1018 wale nō ka 0.18% kalapona a me 0.6-0.9% manganese, ʻoi aku ka liʻiliʻi ma mua o A36.Loaʻa iā ia nā ʻāpana o ka phosphorous a me ka sulfur akā ʻoi aku ka liʻiliʻi o nā haumia ma mua o A36.
Loaʻa nā noi kila 1018 maʻamau:
Na Gears
Pinions
Nā ʻōkalakala
Pahee mea hana aila
Nā pine
Nā pine kaulahao
Nā laina laina
Nā kāʻei
Nā pine heleuma
1011 Pepa kila i olokaa wela
1011 ʻOi aku ka ʻili o ka ʻili ma mua o ke kila ʻōwili a me ka pā.I ka galvanized, hoʻohana ʻia i nā noi kahi e pono ai ke kūpaʻa corrosion.ʻO ka ikaika kiʻekiʻe a me ka palapala kila HR a me ka pā maʻalahi e wili, hana a weld.Hiki ke loaʻa ka pepa kila wela a me ka pā ma ke ʻano he P&O ʻōwili wela maʻamau.
ʻO kekahi o nā pōmaikaʻi e pili ana i ka 1011 hot rolled steel sheet a me ka pā, ʻo ia ka hoʻonui ʻana i ka malleability, kiʻekiʻe o ka hana ʻana, a haʻahaʻa ke hoʻohālikelike ʻia me ka ʻōwili anu.Aia nā noi:

Hot Rolled ASTM A513 Steel
ʻO ka ASTM A513 kikoʻī no nā paipu kila kalapona ʻōwili wela.Hana ʻia nā paipu kila ʻōwili wela e ka hoʻoheheʻe ʻana i ka metala metala wela ma o nā wili e hoʻokō i nā ana kino kikoʻī.ʻO ka huahana i hoʻopau ʻia he ʻeleʻele o ka ʻili me nā kihi radiused a i ʻole kahi hana welded a ʻole paha.Ma muli o kēia mau kumu, ʻoi aku ka maikaʻi o ka paipu kila ʻōwili wela no nā noi ʻaʻole koi i nā ʻano kikoʻī a i ʻole nā ʻae ʻana.
He mea maʻalahi ke ʻoki, weld, ʻano, a me ka mīkini.Hoʻohana ʻia ia i nā noi ʻoihana he nui, e like me:
Piʻi ʻenekini
Nā mea hoʻopāpā
Ke kūkulu hale/kūkulu hale
ʻO nā kaʻa a me nā mea hana e pili ana (trailer, etc.)
ʻOihana ʻenehana
Nā papa lāʻau lā
Nā mea hana hale

Hot Rolled ASTM A786 Steel
ʻO ke kila wela ASTM A786 i ʻōwili ʻia me ka ikaika kiʻekiʻe.Hana ʻia ia no nā papa hehi kila no nā noi penei:
Papa papahele
Alanui
1020/1025 ʻO ke kila i ʻōwili ʻia wela
He kūpono no ke kūkulu ʻana a me nā noi ʻenekinia, 1020/1025 kila ke hoʻohana maʻamau ʻia no kēia mau noi:
Mea hana a make
Nā ʻāpana mīkini
Lako kaʻa
ʻOihana ʻenehana
Inā ʻoe e noʻonoʻo ana e kūʻai i ka ʻōwili wela wela , pepa ʻōwili wela, ʻōwili ʻōwili anu, pā ʻōwili anu, e ʻike i nā koho a JINDALAI iā ʻoe a noʻonoʻo e hoʻopili i kā mākou hui no ka ʻike hou aku.E hāʻawi mākou iā ʻoe i ka hopena maikaʻi loa no kāu papahana.E ʻoluʻolu e kelepona mai iā mākou.
