Paʻa paʻa Paʻa ʻo Hot-rolled steel bar

ʻO nā pahu kila wela ka mea i hoʻopau ʻia i ka ʻōwili wela a hoʻomaha maoli. Hana ʻia lākou me ke kila haʻahaʻa haʻahaʻa a me ke kila kila maʻamau i ka wela kiʻekiʻe. Hoʻohana nui ʻia lākou no ka hoʻoikaika ʻana i nā mea hoʻonaninani i hoʻopaʻa ʻia a prestressed. ʻO kekahi o nā ʻano kila i hoʻohana nui ʻia.
ʻO nā pahu kila i'ōwili wela he mau pahu kila me ke anawaena o 6.5-9 mm, aʻo ka hapa nui o ia mau mea i'ōwiliʻia i nā kaula uwea; ʻO ka poʻe me ke anawaena o 10-40 mm he mau kaola pololei me ka lōʻihi o 6-12 mika. Pono e loaʻa i nā pahu kila wela kahi ikaika, ʻo ia hoʻi ka yield point a me ka ikaika tensile, ʻo ia ke kumu nui no ka hoʻolālā ʻana. Ua māhele ʻia i ʻelua ʻano: ʻo ka pahu kila a puni ka wela a me ka pahu kila ribbed wela. He palupalu a paakiki ka pahu kila wela, a e loaʻa iā ia kahi ʻāʻī i ka wā e haki ai, a nui ka elongation rate.
