ʻIkepili o ka Coil kila i ʻōwili anu ʻia
Hana ʻia ke wili ʻōwili anu me ke wili wela. I ke kaʻina hana ʻōwili anu, ʻōwili ʻia ke wili wela ma lalo o ka mahana recrystallization, a ʻōwili ʻia ke kila i ʻōwili ʻia ma ka mahana o ka lumi. ʻO ka pepa kila me ka nui o ka silicon he haʻahaʻa ka brittleness a me ka plasticity haʻahaʻa, a pono e hoʻomehana mua ʻia i 200 °C ma mua o ka ʻōwili anu. ʻOiai ʻaʻole i hoʻomehana ʻia ke wili anu i ka wā o ke kaʻina hana, ʻaʻohe hemahema e like me ka pitting a me ka hao oxide i loaʻa pinepine i ka ʻōwili wela, a maikaʻi ke ʻano o ka ʻili a me ka hoʻopau ʻana.

Papa ʻōwili anu
1. ʻO ka hōʻailona Kina No. Q195, Q215, Q235, Q275——Q—ke code o ke kiko hua (palena) o ke kila hoʻonohonoho kalapona maʻamau, ʻo ia ke ʻano o ka alphabet phonetic Kina mua o "Qu"; 195, 215, 235, 255, 275 - e hōʻike ana i ka waiwai o kā lākou kiko hua (palena), ke anakahi: MPa MPa (N / mm2); ma muli o nā waiwai mechanical piha o ke kila Q235 ikaika, plasticity, toughness a me ka weldability i ke kila hoʻonohonoho kalapona maʻamau. ʻO ka mea nui loa, hiki iā ia ke hoʻokō maikaʻi i nā koi maʻamau o ka hoʻohana ʻana, no laila ua ākea loa ka laulā o ka noi.
2. ʻO ka lama Kepanī SPCC - Kila, P-Plate, C-anuanu, hā C-maʻamau.
3. Kelemānia papa ST12 - ST-kila (Kila), pepa kila ʻōwili anu 12-papa.
Ka Hoʻohana ʻana o ka Coil Steel Rolled Anu
He hana maikaʻi ko ka ʻōwili anu, ʻo ia hoʻi, ma o ka ʻōwili anu, hiki ke loaʻa ka ʻāpana kila a me ka pepa kila me ka mānoanoa lahilahi a me ka pololei kiʻekiʻe, me ke kiʻekiʻe o ka pololei, ka laumania o ka ʻili kiʻekiʻe, ka ʻili maʻemaʻe a me ka ʻālohilohi o ka pepa ʻōwili anu, a me ka uhi maʻalahi. ʻO ka hana ʻana i uhi ʻia, nā ʻano like ʻole, ka hoʻohana ākea, a me nā ʻano o ka hana kiʻi kiʻekiʻe a me ka ʻelemakule ʻole, kahi hua haʻahaʻa, no laila he ākea ka hoʻohana ʻana o ka pepa ʻōwili anu, hoʻohana nui ʻia i nā kaʻa, nā pahu hao i paʻi ʻia, ke kūkulu ʻana, nā mea kūkulu hale, nā paikikala, a me nā mea ʻē aʻe. ʻO ka ʻoihana kekahi koho maikaʻi loa no ka hana ʻana i nā pepa kila i uhi ʻia me ka organik.
