Pepa ʻōwili anuhe ʻano huahana hou i paʻi hou ʻia a hana ʻia epepa ʻōwili wela. Ma muli o ka nui o nā kaʻina hana ʻōwili anu, ʻoi aku ka maikaʻi o kona ʻili ma mua o ka pepa wela. Ma hope o ka hoʻomaʻamaʻa ʻana i ka wela, ua hoʻomaikaʻi maikaʻi ʻia kona mau ʻano mechanical.
E like me nā koi like ʻole o kēlā me kēia ʻoihana hana,papa ʻōwili anuanuua mahele pinepine ia i mau pae. Hāʻawi ʻia nā lau i ʻōwili ʻia i loko o nā coils a i ʻole nā pepa palahalaha, a ʻike pinepine ʻia kona mānoanoa i nā millimeters. Ma nā ʻōlelo o ka laulā, loaʻa iā lākou ma 1000 mm a me 1250 mm ka nui, aʻo ka lōʻihi he 2000 mm a me 2500 mm. ʻAʻole i loaʻa wale i kēia mau ʻāpana ʻōwili anuanu nā waiwai hoʻokumu maikaʻi a me ka maikaʻi o ka ʻili, akā maikaʻi nō hoʻi i ka pale ʻana i ka corrosion, kūpaʻa luhi a me nā aesthetics. ʻO ka hopena, hoʻohana nui ʻia lākou i ka automotive, ke kūkulu ʻana, nā mea hana hale, nā mea ʻenehana a me nā ʻano ʻē aʻe.
Nā papa o ka pepa ʻōwili maʻamau
ʻO nā māka i hoʻohana mau ʻia:
Q195, Q215, Q235, 08AL, SPCC, SPCD, SPCE, SPCEN, ST12, ST13, ST14, ST15, ST16, DC01, DC03, DC04, DC05, DC06 a pēlā aku;
ST12: Hōʻike ʻia e like me ke kila kila maʻamau, me Q195,SPCC, DC01'ano like 'ole ka mea papa;
ST13/14: Hōʻike ʻia no ka hoʻopaʻa ʻana i ka helu kila, a ʻo 08AL, SPCD, DC03/04 ka mea ma ke ʻano like;
ST15/16: Hōʻike ʻia e like me ka helu kila kila, a ʻo 08AL, SPCE, SPCEN, DC05/06 mau mea papa he mea like.
ʻO ka manaʻo maʻamau o Iapana JIS
He aha ke ʻano o SPCCT a me SPCD?
ʻO ka SPCCT, ʻo ia hoʻi, ʻo ia hoʻi ka pepa kila kalapona i ʻōwili ʻia anuanu me ka ikaika tensile hōʻoiaʻiʻo ʻia ma lalo o ke kūlana JIS Iapana, ʻoiai ʻo SPCD ʻo ia hoʻi ka pepa kila kalapona i ʻōwili ʻia anu a me ke kāʻei no ka hoʻopaʻa ʻana ma lalo o ke kūlana JIS Iapana, a ʻo kāna hoa Pākē ʻo 08AL (13237) kūlana kiʻekiʻe. kila.
Eia kekahi, e pili ana i ke code tempering o ka pepa kila kalapona i ʻōwili ʻia a me ka strip, ʻo ke kūlana annealed ʻo A, ʻo S ka hoʻomaʻamaʻa maʻamau, ʻo 1/8 ka paʻakikī he 8, 1/4 ka paʻakikī ʻo 4, 1/2 ka paʻakikī ʻo 2, a piha. ʻO ka paʻakikī ʻo 1. ʻO ka helu hoʻopau o ka ʻili ʻo D no ka pau ʻana i ka ʻālohilohi, a me ka B no ka pau ʻālohilohi, e laʻa, SPCC-SD e hōʻike ana i ka pepa kila kalapona i ʻōwili ʻia no ka hoʻohana maʻamau me ka hoʻomaʻamaʻa maʻamau a me ka pau ʻole o ka ʻōlinolino; Hōʻike ka SPCCT-SB i ka maʻamau maʻamau, hoʻopau ʻālohilohi ka pepa kila kalapona i ʻōwili ʻia; a me ka SPCCT-SB e hōʻike ana i ka maʻamau maʻamau, hoʻopau ʻālohilohi i ka pepa kila kalapona ʻōwili ʻia no ka hoʻohana maʻamau me ka hoʻomaʻamaʻa maʻamau a me ka hoʻopau ʻole. ʻO ka hoʻomaʻamaʻa maʻamau, ka hana ʻālohilohi, ka pepa kalapona i ʻōwili ʻia e pono ai e hōʻoia i nā waiwai mechanical; Hōʻike ʻia ʻo SPCC-1D ma ke ʻano he paʻakikī paʻa ʻole i ʻōwili ʻia ka pepa kila kalapona i ʻōwili ʻia.
Mechanical structural kila papa ua hōʻike 'ia penei: S + kalapona maʻiʻo + leka helu (C, CK), o ka carbon maʻiʻo me ka median waiwai * 100, ka huapalapala C 'o ia hoʻi ke kalapona, ka huapalapala K 'o ia hoʻi carburized kila.
ʻO ka manaʻo maʻamau o Kina GB
Hoʻokaʻawale nui ʻia i: Q195, Q215, Q235, Q255, Q275, a me nā mea ʻē aʻe Q hōʻike i ka helu o ke kila "hua" i ka leka mua o ka huaʻōlelo hanyu pinyin, 195, 215, etc. ʻO ka hui kemika mai nā kiko, haʻahaʻa carbon steel grade: Q195, Q215, Q235, Q255, Q275 grade, ʻoi aku ka nui o ke kalapona, ʻoi aku ka kiʻekiʻe o ka ʻike manganese, ʻoi aku ka paʻa o kona plasticity.
