Nā ʻano a me nā hiʻohiʻona o ke kila, a he aha nā ʻano nui ʻehā o ke kila？

1 、He aha nā ʻano kila

1. 40Cr, 42CrMo, a me nā mea ʻē aʻe: E pili ana i ke kila structural alloy, nona ka ikaika kiʻekiʻe kiʻekiʻe a me ke kūpaʻa luhi, a hoʻohana mau ʻia e hana i nā mea nui o nā lako mīkini nui.ʻO ke kumu hoʻohālike kila maʻamau ʻo ASTM A3 he kila maʻamau kalapona maʻamau maʻamau ʻAmelika, nona nā ʻano mechanical haʻahaʻa a hoʻohana mau ʻia i ka hana ʻana i nā mea hana maʻamau.

2. ʻO nāʻano nui o ke kila,ʻo ia ke kila kūikawā kūikawā, ke kila kila, ke kila puna kalapona, ke kila puna kila, ke kila kila, ke kila kila, ke kila kila, ke kila kila, ke kila kila kiʻekiʻe, ke kila kiʻekiʻe, ke kila kila. , ke kila wela, a me nā mea wela wela, nā mea hoʻoheheʻe pololei, a me nā mea electrothermal.

3. Waiwai E: 26 no nā kumu hoʻohālike maʻamau a me nā mea me a, 44 no ka poʻe me ka b, a me 24 no ka poʻe me c.Aia kēlā me kēia ʻāpana lōʻihi i nā millimeters.ʻO nā ana lōʻihi kila e pili ana i nā ana kumu o nā ʻano kila like ʻole, e like me ka lōʻihi, ka laula, ke kiʻekiʻe, ke anawaena, ka radius, ke anawaena o loko, ke anawaena o waho, a me ka mānoanoa o ka pā.

4. Hoʻokaʻawale ʻia ke kila i ʻehā mau ʻāpana: profiles, plates, building materials, and pipes.Hoʻokaʻawale ʻia nā mea waiwai o nā profiles a me nā papa e like me Q235B, Q345B, a me Q355B, ʻoiai ʻo ka mea nui o nā mea kūkulu hale ʻo HRB400E, a ʻo ka mea nui o nā paipu he Q235B.

ʻO ke ʻano o nā profiles e pili ana i ke kila H-like, I-like steel, channel steel, a me ke kila kihi.

5. Ke kila kūikawā: e pili ana i ke kila kūikawā i hoʻohanaʻia ma nāʻoihanaʻoihana likeʻole, e like me ke kila kaʻa, ke kila mīkini mahiʻai, ke kila lele, ke kila hana mechanical, ke kila umu ahi, ke kila uila, ka uwea welding, a me nā mea'ē aʻe. ʻOkoʻa nā kikoʻī o nā huahana paipu welded like ʻole, maʻamau i hōʻike ʻia i ka anawaena nominal.

2、 Pehea e ʻike ai i nā ʻano a me nā hiʻohiʻona o ke kila

1. E like me nā hoʻohana like ʻole a me nā koi, hiki ke hoʻokaʻawale ʻia ke kila i nā ʻano like ʻole a me nā hiʻohiʻona.ʻO ke kila kalapona i hoʻokaʻawale ʻia e ka haku mele: ʻO ke kila me kahi ʻāpana kalapona ma waena o 008% a me 11%, hoʻohana nui ʻia no ka hana ʻana i nā ʻāpana mechanical, nā huila, nā ala, etc.

2. Ka wehewehe wehewehe ʻana o ke kaʻina hana hōʻike kila ma Kina: 1. Hoʻokumu ʻia ke kila kila me ka Q + helu + hōʻailona papa maikaʻi + hōʻailona deoxygenation method.Hoʻopili mua ʻia kona papa kila me "Q", e hōʻike ana i ka helu hua o ke kila, a ʻo nā helu ma lalo e hōʻike ana i ka waiwai o ka hua, ma MPa.No ka laʻana, hōʻike ʻo Q235 i ke kiko hoʻohua（ σ s) 23 MPa kila kila.

3. Hoʻokaʻawale ʻia ke kila i ʻehā ʻano: profiles, plates, building materials, and pipes.Ma waena o lākou, hiki ke hoʻokaʻawale ʻia nā profiles a me nā papa i Q235B, Q345B, a me Q355B, aʻo nā mea kūkulu hale ʻo HRB400E a ʻo nā paipu he Q235B.Hiki ke hoʻokaʻawale ʻia nā ʻano o nā profiles i ke kila H-like, ke kila I-like, a pēlā aku.

4. Ke kila forged;Ke kila kila;Ke kila ʻōwili wela;Ke kila huki anu.ʻO ke kila i hoʻokaʻawale ʻia e ka hoʻolālā metallographic ma ke kūlana annealed: ① kila hypoeutectoid (ferrite+pearlite);② Ke kila Eutectoid (pearlite);③ Ka ua kila mai ke kila eutectic (pearlite+cementite);④ Ke kila ʻē aʻe (pearlite+cementite).

5. ʻO ke kila anuanu: he ʻano kila i hana ʻia e ke kila kulou anuanu a i ʻole nā ​​ʻāpana kila.Kiʻekiʻe kūlana kiʻekiʻe: High quality poepoe kila, huinahalike kila, palahalaha kila, hexagonal kila, etc.Pepa metala;Pā kila lahilahi: He pā kila me ka mānoanoa o 4 millimeters a i ʻole.Nā pā kila waena a me ka mānoanoa: Nā pā kila me ka mānoanoa oi aku ma mua o 4 millimeters.

6. Hōʻike ka helu i ka waiwai helu hua, no ka laʻana, Q275 hōʻike i kahi kiko o 275Mpa.Inā hōʻailona ʻia nā leka A, B, C, a me D ma hope o ka papa, e hōʻike ana he ʻokoʻa ka pae maikaʻi o ke kila, a ʻo ka nui o S a me P e emi maʻamau, ʻoiai ke piʻi nui ka maikaʻi o ke kila.
