Nūhou - Introduction to Hot-Rolled Steel Coils: Properties & Uses

Hoʻolauna iʻO nā wili kila i ʻōwili ʻia wela
ʻO nā wili kila wela ka mea waiwai nui i hana ʻia e ka hoʻomehana ʻana i nā papa kila ma luna o ka wela o ka recrystallization (maʻamau 1,100–1,250 ° C) a ʻōwili iā lākou i loko o nā ʻāpana mau, a laila wili ʻia no ka mālama ʻana a me ka lawe ʻana. Ke hoʻohālikelike ʻia me nā huahana anuanu, ʻoi aku ka maikaʻi o ka ductility a me ke kumu kūʻai, hoʻohana nui ʻia lākou i nā ʻoihana like ʻole ma ka honua.

Kaʻina Hana Hana
ʻO ka hana ʻana oPuka hao hao i olokaa welapili i nā ʻanuʻu kī ʻehā. ʻO ka mea mua, ka hoʻomehana papa: Hoʻomaʻamaʻa ʻia nā papa kila i loko o kahi kapuahi hele wāwae e hōʻoia i ka mahana like ʻole. 'O ka lua, 'oloka'a 'o'ole'a: 'Oloka'a 'ia nā papa i ho'omehana 'ia i loko o nā billet waena me ka mānoanoa o 20-50mm e nā wili wili. ʻO ke kolu, hoʻopau i ka ʻōwili ʻana: Ua ʻōwili hou ʻia nā pila waena i mau ʻāpana lahilahi (1.2–25.4mm mānoanoa) ma ka hoʻopau ʻana i nā wili. ʻO ka hope, wili a hoʻoluʻu: Hoʻomaʻalili ʻia nā ʻāpana wela i kahi mahana kūpono a hoʻopili ʻia i loko o nā coils e kahi downcoiler.

Mea maʻamau ma Asia Hikina Hema

Papa Mea	Nā mea nui	Na Waiwai Ki	Hoʻohana maʻamau
SS400 (JIS)	C, Si, Mn	ikaika kiʻekiʻe, weldability maikaʻi	Ke kūkulu ʻia, nā papa mīkini
Q235B (GB)	C, Mn	Maikaʻi formability, haʻahaʻa kumu kūʻai	Nā alahaka, nā pahu mālama
A36 (ASTM)	C, Mn, P, S	ʻO ka paʻakikī kiʻekiʻe, ke kū'ē i ka corrosion	Ka hana moku, ʻāpana kaʻa

Nui maʻamau
Ka laulā mānoanoa maʻamau oHR Steel Coilsʻo 1.2–25.4mm, a ʻo ka laulā he 900–1,800mm. Hoʻololi ke kaumaha o ka coil mai 10 a 30 tons, hiki ke hoʻololi ʻia e like me nā koi o ka mea kūʻai aku.

Nā ʻano hoʻopaʻa ʻana
No ka hōʻoia ʻana i ka palekana o ka lawe ʻana, ua hoʻopili pono ʻia nā wili kila wela. Hoʻopili mua ʻia lākou me ka pepa kraft wai ʻole, a laila uhi ʻia me kahi kiʻiʻoniʻoni polyethylene e pale ai i ka makū. Hoʻohana ʻia nā ʻāpana kila no ka hoʻoponopono ʻana i nā wili ma nā pale lāʻau, a hoʻohui ʻia nā pale pale e pale aku i ka pōʻino o ka lihi.

Nā hiʻohiʻona noiʻi
Hana Hana: Hoʻohana ʻia e hana i nā kaola kila, nā kolamu, a me nā papa papahele no nā hale kiʻekiʻe a me nā hale hana.
ʻOihana Kaʻa: Hana i nā papa chassis a me nā ʻāpana hana ma muli o ka ikaika maikaʻi.
ʻOihana Paipu: Hoʻopuka i nā paipu kila nui no ka lawe ʻana i ka aila a me ke kinoea.
ʻOihana Mea Hana Hale: Hana i nā pahu o waho o nā pahu hau a me nā mīkini holoi no ke kumu kūʻai.

Ma ke ʻano he huahana pōhaku kihi i ka ʻoihana hana honua a me ke kūkulu hale,ʻO nā Coils Steel Carbone kū i waho no kā lākou hana kaulike, nā uku kumukūʻai, a me ka hiki ke hoʻololi ākea - nā hiʻohiʻona e kūpono loa iā lākou i nā ʻoihana ulu a me nā pono ʻoihana. Inā makemake ʻoe iā SS400 no nā hana kūkulu, Q235B no nā pahu mālama, a i ʻole A36 no nā ʻāpana kaʻa, ʻo kā mākou coils kila wela e hoʻokō i nā kūlana koʻikoʻi, me nā nui i hoʻopili ʻia a me ka hōʻailona hilinaʻi e hōʻoia i ka lawe palekana.
Inā makemake ʻoe e aʻo hou aʻe e pili ana i kā mākou huahana kikoʻī, loaʻa i kahi kikoʻī kikoʻī, a i ʻole ke kūkākūkā ʻana i nā hoʻonā i hoʻohālikelike ʻia no kāu mau pono kikoʻī (e like me nā paona coil maʻamau a i ʻole nā papahana waiwai), e ʻoluʻolu e kelepona iā mākou i kēlā me kēia manawa. Mākaukau kā mākou hui e hāʻawi i ke kākoʻo ʻoihana a kōkua iā ʻoe i ka loaʻa ʻana o nā ʻōnaehana coil kila wela wela no kāu ʻoihana.
