SPCC Cold Rolled Steel Coil

ʻO ka wehewehe pōkole:

Inoa: Cold Rolled Steel Coil

ʻO ke kila kalapona anuanu (SPCC, SPCD, SPCE), ke kila kalapona haʻahaʻa a me ke kila kalapona haʻahaʻa loa (DC01/St12, DC03/St13, DC04/St14), ke kila stamping automotive (DC01-Q1, DC03-Q1, DC04 - Q1), nā ʻāpana kila hoʻoheheʻe kalapona i ʻōwili ʻia (Q235, St37-2G, S215G), nā ʻāpana kila kiʻekiʻe kiʻekiʻe (JG300LA, JG340LA), etc.

Mānoanoa: 0.1mm-0.45mm

laula laula: 700mm-1000mm

Mea: SPCC, SPCC, SPCD, SPCE, DC01, St12, DC03, St13, DC04, St14, Q235, St37-2G, S215G, JG300LA, JG340LA

Nā hiʻohiʻona: No ka mea ʻaʻole i hoʻopili ʻia, ua kiʻekiʻe loa kona paʻakikī (ʻoi aku ka nui o ka HRB ma mua o 90), a ʻilihune loa ka hana machining. Hiki ke hana ʻia kahi kaʻina hana kulou maʻalahi ma lalo o 90 degere (kūpono i ka ʻōkuhi wili). Hiki i kekahi mau wili kila ke hana i ka hana ʻehā.

Ka nānā 'ana o ka coil wili anu

Hana ʻia ka ʻōwili anuanu me ka ʻōwili wela wela. Ma ke kaʻina hana ʻōwili anu, ʻōwili ʻia ka ʻōwili wela ma lalo o ka mahana recrystallization, a ʻōwili ʻia ke kila i ʻōwili ʻia ma ka lumi wela. He haʻahaʻa haʻahaʻa ka haʻahaʻa haʻahaʻa a me ka haʻahaʻa haʻahaʻa ka pepa kila me ka ʻike silika kiʻekiʻe, a pono e hoʻomehana ʻia i 200 °C ma mua o ka ʻōwili ʻana. No ka mea, ʻaʻole i hoʻomehana ʻia ka coil i ʻōwili ʻia i ka wā o ke kaʻina hana, ʻaʻohe hemahema e like me ka pitting a me ka hao oxide i ʻike pinepine ʻia i ka ʻōwili wela, a maikaʻi ka maikaʻi o ka ʻili a me ka hopena.

Kaʻina Hana Hana ʻAi ʻAi ʻO Cold Rolled Coil

Hana ʻia ka coil ʻōwili wela, a ʻo kāna kaʻina hana maʻamau e hele i nā kaʻina hana nui e like me ka hoʻomākaukau ʻana i nā mea maka, ka ʻōwili anu, ka mālama wela, ka pae a me ka hoʻopau ʻana.

ʻO Cold Rolled Coil Product performance

ʻO ka ʻōwili a me ka papa ʻaina kokoke i kahi pūʻolo ʻoki. Loaʻa ʻia ka coil chilled ma ka pickling a me ka ʻōwili anuanu i ka ʻōwili wela wela. Hiki ke ʻōlelo ʻia he ʻano wili anuanu. Cold rolled coil (annealed state): Loa'a ka wili wela wela ma ka pickling, cold rolling, hood annealing, leveling, (finishing).

Aia 3 mau ʻokoʻa nui ma waena o lākou:

I ka nānā ʻana, ʻaʻohe palahe ka wili maʻamau maʻamau.

ʻOi aku ka maikaʻi o nā lau i ʻōwili ʻia e like me ka maikaʻi o ka ʻili, ka hoʻolālā a me ka pololei o ka dimensional ma mua o nā coils chilled.

Ma ke ʻano o ka hana, ʻo ka coil chilled i loaʻa pololei ma hope o ke kaʻina hana ʻōwili o ka ʻōwili wela wela e hana paʻakikī i ka wā o ka ʻōwili anu, e hopena i ka hoʻonui ʻana i ka ikaika a me kahi ʻāpana o ke koʻikoʻi o loko i koe, a ʻo ka hiʻohiʻona o waho he "paʻakikī. ". Kapa ʻia ʻo ia ka coil chilled.

No laila, ʻoi aku ka ikaika o ka hāʻawi ʻana: ʻoi aku ka nui o ka coil chilled ma mua o ka coil i ʻōwili ʻia (annealed state), i ʻoi aku ka maikaʻi o ka coil-rolled coil (annealed state) no ka stamping. ʻO ka maʻamau, ua hoʻopili ʻia ke kūlana hoʻopuka paʻamau o nā coils i ʻōwili ʻia.
