Kila Q195, Q235, ka ʻokoʻa o ka mea?

He aha ka ʻokoʻa ma waena o Q195, Q215, Q235, Q255 a me Q275 ma ke ʻano o nā mea?

ʻO ke kila kila kalapona ka mea i hoʻohana nui ʻia, ʻo ka nui o nā ʻano kila i hana pinepine ʻia, ʻo ia hoʻi nā ʻano kila a me nā ʻano kila, ʻaʻole pono e hoʻohana pololei ʻia i ka wela, ʻoiai no ka hoʻohana ʻana i ka ʻōnaehana hana maʻamau a me ka ʻenekinia.

ʻO Q195, Q215, Q235, Q255 a me Q275, a pēlā aku, e hōʻike ana i ke ʻano o ke kila, ʻo ke kila kila e ka ʻelele o ke kiko hua o ka leka (Q), ka waiwai kiko hua, ka maikaʻi, ka maikaʻi a me nā hōʻailona ʻē aʻe (A, B, C, D) ke ʻano deoxygenation o nā hōʻailona a pēlā aku ma nā ʻāpana ʻehā o ka haku mele ʻana. Mai ka haku mele kemika, ʻo nā māka kila akahai Q195, Q215, Q235, Q255 a me Q275 he nui, ʻoi aku ke kiʻekiʻe o ka ʻike kalapona, ka ʻike manganese, ʻoi aku ka paʻa o kona plasticity. Mai nā kiko mechanical, ʻo nā māka ma luna e hōʻike ana i ka mānoanoa ≤ 16mm o ke kiko hua o ke kila. ʻO kona ikaika tensile: 315-430, 335-450, 375-500, 410-550, 490-630 (obN/mm2); ʻO nā qi kona elongation: 33, 31, 26, 24, 20 (0.5%). No laila, i ka hoʻolauna ʻana i ke kila i nā mea kūʻai aku, pono e hoʻomanaʻo ʻia nā mea kūʻai aku e kūʻai i nā mea kila like ʻole e like me nā mea huahana e pono ai, i ʻole e hoʻopilikia i ka maikaʻi o ka huahana.

 

He aha ka ʻokoʻa ma waena o nā mea Q235A a me Q235B?

ʻO Q235A a me Q235B he kila kalapona. Ma ke kūlana aupuni GB700-88, ʻo ka ʻokoʻa o nā mea Q235A a me Q235B ma ke ʻano nui o ka nui o ke kalapona o ke kila, ʻo ka nui o ke kalapona o ka mea no ka mea Q235A ma waena o 0.14-0.22 ﹪; ʻAʻole hana ka mea Q235B i ka hoʻāʻo hopena, akā hana pinepine i ka hoʻāʻo hopena mahana, V-notch. I ka hoʻohālikelike ʻana, ʻoi aku ka maikaʻi o nā waiwai mechanical o ke kila Q235B ma mua o ke kila Q235A. Ma keʻano laulā, ua hōʻailona ʻia ka wili kila ma nā ʻaoʻao i hoʻopau ʻia ma mua o ka haʻalele ʻana i ka hale hana ma ka papa hōʻike. Hiki i nā mea hoʻohana ke ʻike inā he Q235A, Q235B, a i ʻole nā ​​​​mea ʻē aʻe ma ka papa hōʻailona.

 

ʻO nā papa kila Kepanī ʻo SPHC, SPHD, a pēlā aku. He aha ke ʻano o lākou?

ʻO nā papa kila Kepani (JIS series) o ke kila kūkulu maʻamau he ʻekolu ʻāpana nui: ʻo ka hapa mua e hōʻike ana i ka mea, e like me: S (Steel) ʻo ia ke kila, F (Ferrum) ʻo ia ka hao. ʻO ka hapa ʻelua o nā ʻano like ʻole, nā ʻano, nā hoʻohana, e like me P (plate) kēlā papa, T (tube), K (kogu) kēlā mea hana. ʻO ke kolu o ka hapa o nā ʻano o ka papa ʻaina o ka helu, ma ke ʻano maʻamau ka ikaika tensile liʻiliʻi. E like me: ss400 - ʻo ka s mua ke kila (Ssteel), ʻo ka lua s ka "structure" (Structuree), 400 no ka laina haʻahaʻa o ka ikaika laina o 400Mpa kila kūkulu maʻamau. I waena o lākou: sphc ---- ʻo ka pōkole Ssteel Steel mua, P no ka pōkole Pate papa, H no ka pōkole wela Heat, pōkole Commercial, ʻo ka holoʻokoʻa e hōʻike ana i ka laulā wela-ʻōwili a me ke kila kila.

 

Hōʻike ʻo SPHD----- i ka pepa kila i ʻōwili wela ʻia a me ke kaha no ka hehi ʻana.

Hōʻike ʻo SPHE------ i nā pepa kila i ʻōwili wela ʻia a me nā ʻāpana no ke kahakiʻi hohonu.

Hōʻike ʻo SPCC------ i ka pepa kila kalapona i ʻōwili anu ʻia a me ke kaula no ka hoʻohana maʻamau, e like me ka papa Kina Q195-215A. ʻO ke kolu o ka leka C he pōkole no ke Anu, kahi e pono ai e hōʻoia i ka hoʻāʻo tensile ma ka hopena o ka papa me T no SPCCT.

Hōʻike ʻo SPCD------ i ke kila kalapona i ʻōwili anu ʻia a me ke kaula kila no ka punching, e like me ke kila kūkulu kalapona kiʻekiʻe o Kina 08AL (13237).

Hōʻike ʻo SPCE------ i ka pepa kila kalapona i ʻōwili anu ʻia a me ke kaha no ke kaha hohonu ʻana, e like me ke kila punching Kina 08AL (5213). I mea e hōʻoia ai i ka hana ʻole, e hoʻohui iā N i ka SPCEN ma ka hopena o ka papa.

ʻO ka pepa kila kalapona i ʻōwili anu ʻia a me ka hoʻolālā ʻāpana, ke kūlana annealed no A, hoʻomaʻamaʻa maʻamau no S, 1/8 paʻakikī no 8, 1/4 paʻakikī no 4, 1/2 paʻakikī no 2.

ʻAno hoʻopau ʻili: ʻaʻohe hoʻopau ʻana o ka ʻōlinolino no D, hoʻopau ʻana o ka ʻōlinolino no B. E like me ka SPCCT-SD e hōʻike ana i ka pepa kalapona i ʻōwili anu ʻia no ka hoʻohana maʻamau, ʻaʻohe hoʻopau ʻana o ka ʻōlinolino. A laila hōʻike ʻo SPCCT-SB i ka pepa kalapona i ʻōwili anu ʻia, i hoʻopau ʻia me ka ʻālohilohi me nā waiwai mechanical i hōʻoia ʻia.
