ʻO kahi hōʻike hohonu o nā ʻāpana kumu a me nā waiwai o ka Coil Steel Hot-Rolled: Mai ka hana ʻana i ka noi.

Hoʻomaka ka hana ʻana o ka coil carbon steel ma kawili kalaponahale hana, kahi e hana ʻia ai nā billet i loko o nā coils o nā kikoʻī kikoʻī ma o ke kaʻina ʻōwili wela kiʻekiʻe. ʻo kahi laʻana,ASTM A36 wili kilahe kila kila maʻamau i ʻōlelo ʻia e ka American Society for Testing and Materials (ASTM) maʻamau a makemake nui ʻia ma ke kūkulu ʻana a me nā kahua ʻenekinia. Hāʻawi ka ASTM A36 coil i ka ikaika o ka ≥250 MPa a me ka ikaika tensile o 400-550 MPa, me ka ductility maikaʻi loa a me ka weldability, e hoʻokō ana i ka ukana a me nā koi pili o nā hale nui e like me nā alahaka a me nā papa hana. ʻO kāna mea hoʻohui kemika e mālama mau i ka ʻike kalapona ma lalo o 0.25%, e hoʻohālikelike pono i ka ikaika a me ka paʻakikī me ka pale ʻana i ka embrittlement e pili ana me ka nui o ka carbon content.

Mai kahi hiʻohiʻona hoʻohālikelike, ʻo ka mānoanoa, ka laulā, a me ke kaumaha o ka coil he mau hōʻailona koʻikoʻi no ka loiloi ʻana i ka hana o nā wili kila wela. ʻO nā mānoanoa maʻamau mai ka 1.2 a i ka 25.4 mm, ʻoiai hiki i nā laula ke ʻoi aku ma mua o 2000 mm. Hiki ke hoʻohālikelike ʻia ke kaumaha o ka coil, maʻamau mai 10 a 30 tons. ʻAʻole pili wale ka mana o ka dimensional pololei i ka pono o ka hoʻoponopono ʻana akā pili pū kekahi i ka pololei o ka huahana hope. No ka laʻana, pono e hoʻomalu pono ʻia ka mānoanoa o nā wili kila wela i hoʻohana ʻia i ka hana kaʻa i loko o ± 0.05 mm e hōʻoia i ka nui o nā ʻāpana i hoʻopaʻa ʻia.
