kila poepoe
Pili ke kila poepoe i ke kila paa me ka pauku kea poepoe.Hōʻike ʻia kāna mau kikoʻī i ke anawaena, i ka millimeters (mm), e like me "50mm" ʻo ia hoʻi ke kila poepoe me ke anawaena o 50 mm.
Ua māhele ʻia ke kila poepoe i ʻekolu ʻano: ʻōwili wela, kālai ʻia a huki ʻia ke anu.ʻO nā kikoʻī o ke kila a puni wela he 5.5-250 mm.Ma waena o lākou: 5.5-25 mm ke kila liʻiliʻi liʻiliʻi i hāʻawi ʻia i loko o nā pūʻulu o nā ʻāpana pololei, i hoʻohana pinepine ʻia e like me nā pahu kila, nā bolts a me nā ʻāpana mechanical like ʻole;ʻO ke kila pōʻai ʻoi aku ka nui ma mua o 25 mm e hoʻohana nui ʻia no ka hana ʻana i nā ʻāpana mechanical a me nā pahu pahu o nā paipu kila ʻole e kali.
Hoʻokaʻawale lāʻau pōʻai
1.Hoʻokaʻawale ʻia e ka haku melemele
Hiki ke hoʻokaʻawale ʻia ke kila kalapona i ke kila kalapona haʻahaʻa, ke kila kalapona waena a me ke kila kalapona kiʻekiʻe e like me ka haku mele ʻana (ʻo ia hoʻi, carbon content).
(1) Ke kila māmā
ʻIke ʻia hoʻi he kila māmā, ʻo ka ʻike kalapona mai 0.10% a 0.30%.He maʻalahi ke kalapona kalapona haʻahaʻa e ʻae i nā hana like ʻole e like me ka forging, welding a me ka ʻoki ʻana, a hoʻohana pinepine ʻia e hana i nā kaulahao, rivets, bolts, shafts, etc.
(2) Medium carbon steel
ʻO ke kila kalapona me kahi maʻi kalapona o 0.25% a 0.60%.Aia nā kila pepehi, kila semi-kiled, kila paila a me nā huahana ʻē aʻe.Ma waho aʻe o ke kalapona, hiki ke loaʻa i kahi liʻiliʻi o ka manganese (0.70% a 1.20%).E like me ka maikaʻi o ka huahana, ua hoʻokaʻawale ʻia i ke kila kila kila a me ke kila kila kila kiʻekiʻe.ʻO ka hana wela maikaʻi a me ka hana ʻoki ʻana, maikaʻi ʻole ka hana kuʻi ʻana.ʻOi aku ka ikaika a me ka paʻakikī ma mua o ke kila kalapona haʻahaʻa, akā ʻoi aku ka haʻahaʻa o ka plasticity a me ka paʻakikī ma mua o ke kila kalapona haʻahaʻa.Hiki ke hoʻohana pololei ʻia nā mea ʻōwili wela a huki ʻia me ka ʻole o ka mālama wela, a i ʻole ma hope o ka mālama ʻana i ka wela.ʻO ke kila kalapona maʻamau ma hope o ke kinai ʻana a me ka hoʻoulu ʻana he mau waiwai mechanical piha.ʻO ka paʻakikī kiʻekiʻe loa e hiki ke loaʻa ma kahi o HRC55 (HB538), a ʻo σb ʻo 600-1100MPa.No laila, i nā hoʻohana like ʻole o ka pae ikaika waena, ʻo ke kila kalapona ka mea i hoʻohana nui ʻia.Ma waho aʻe o ka hoʻohana ʻia ʻana e like me nā mea kūkulu hale, hoʻohana nui ʻia i ka hana ʻana i nā ʻāpana mechanical like ʻole.
(3) Ke kila kalapona kiʻekiʻe
Kapa pinepine ʻia he kila kila, ʻo ka ʻike kalapona mai ka 0.60% a i ka 1.70%, a hiki ke paʻakikī a paʻakikī.ʻO nā hāmare, nā crowbars, a me nā mea'ē aʻe i hanaʻia i ke kila me kahi carbon content o 0.75%;ʻO nā mea hana ʻoki e like me nā drills, taps, reamers, etc. ua hana ʻia i ke kila me ka ʻona kalapona o 0.90% a 1.00%.
2.Hoʻokaʻawale ʻia e ka maikaʻi kila
E like me ka maikaʻi o ke kila, hiki ke hoʻokaʻawale ʻia i ke kila kalapona maʻamau a me ke kila kalapona kiʻekiʻe.
(1) ʻO ke kila kalapona maʻamau, ʻike ʻia hoʻi he kila kalapona maʻamau, he mau palena ākea i ka ʻike kalapona, ka pae hana, a me ka ʻike o ka phosphorus, sulfur a me nā mea koena ʻē aʻe.Ma Kina a me kekahi mau ʻāina, ua māhele ʻia i ʻekolu mau ʻāpana e like me nā kūlana hōʻoia o ka lawe ʻana: ʻO ke kila kila (Class A steel) ke kila me nā waiwai mechanical i hōʻoia ʻia.ʻO ke kila B (Class B steel) he kila me ka hoʻohui kemika i hoʻopaʻa ʻia.ʻO ke kila kūikawā (C-type steel) he kila e hōʻoiaʻiʻo ana i nā waiwai mechanical a me ka haku mele, a hoʻohana pinepine ʻia no ka hana ʻana i nā ʻāpana koʻikoʻi.Ke hana nei ʻo Kina i kēia manawa a hoʻohana i ka kila A3 loa (Class A No. 3 steel) me kahi kalapona ma kahi o 0.20%, i hoʻohana nui ʻia no nā hale ʻenekinia.
Hoʻohui pū kekahi mau mea hao kalapona i ka nui o ka alumini a i ʻole ka niobium (a i ʻole nā mea hana carbide ʻē aʻe) e hana i nā nitrides a i ʻole nā particle carbide e kaupalena i ka ulu ʻana o ka palaoa.No ka ʻike hou aku o CNC, e ʻimi i ka moʻokāki lehulehu "NC programming teaching" ma WeChat, E hoʻoikaika i ke kila a mālama i ke kila.Ma Kina a me kekahi mau ʻāina, i mea e hoʻokō ai i nā koi kūikawā o ke kila ʻoihana, ua hoʻoponopono ʻia ke ʻano kemika a me nā waiwai o ke kila kalapona maʻamau, pēlā e hoʻomohala ai i kahi ʻano kila kila o ke kila kila maʻamau (e like me nā alahaka, nā hale, ʻO nā pahu kila, nā kila no nā moku kaomi, etc.).
(2) Ke hoʻohālikelike ʻia me ke kila kalapona maʻamau, ʻoi aku ka haʻahaʻa o ke kila carbon structural kiʻekiʻe i ka sulfur, phosphorus a me nā mea hoʻohui ʻole.Wahi a ka ʻokoʻa kalapona a me ka hoʻohana ʻana, hiki ke hoʻokaʻawale ʻia kēia ʻano kila i ʻekolu mau ʻāpana:
① ʻOi aku ka liʻiliʻi o 0.25% C he kila haʻahaʻa haʻahaʻa, ʻoi aku ka 08F a me 08Al me kahi maʻi kalapona ma lalo o 0.10%, ua hoʻohana nui ʻia e like me nā ʻāpana huki hohonu e like me nā kaʻa a me nā kini no ka maikaʻi o ka huki hohonu a me ka weldability …… kali. .ʻO 20G ka mea nui no ka hana ʻana i nā paila maʻamau.Eia kekahi, hoʻohana nui ʻia ke kila kalapona haʻahaʻa e like me ke kila carburizing no ka hana mīkini.
ʻO ②0.25～0.60%C he kila kalapona maʻamau, ka mea i hoʻohana nui ʻia i ka moku i hoʻopaʻa ʻia a hoʻohaʻahaʻa ʻia e hana i nā ʻāpana i ka ʻoihana hana mīkini.
③ ʻOi aku ma mua o 0.6% C ke kila kalapona kiʻekiʻe, ka mea i hoʻohana nui ʻia i ka hana ʻana i nā pūnāwai, nā mea ʻoni, nā ʻōwili, a me nā mea ʻē aʻe. %) a me ka nui o ka manganese (0.7-1.0% a me 0.9-1.2%).Hiki i ka Manganese ke hoʻomaikaʻi i ka paʻakikī o ke kila, hoʻoikaika i ka ferrite, a hoʻomaikaʻi i ka ikaika hua, ka ikaika tensile a me ke kūpaʻa o ke kila.ʻO ka mea maʻamau, hoʻohui ʻia ka māka "Mn" ma hope o ka pae o ke kila me nā mea manganese kiʻekiʻe, e like me 15Mn a me 20Mn, e hoʻokaʻawale iā ia mai ke kila kalapona me nā mea manganese maʻamau.
3.Hoʻokaʻawale ma ke kumu
Wahi a ka noi, hiki ke hoʻokaʻawale ʻia i ke kila kila a me ke kila kila.
ʻO ke kila mea hana kalapona Aia ma waena o 0.65 a me 1.35%.Ma hope o ka mālama ʻana i ka wela, hiki ke loaʻa ka paʻakikī kiʻekiʻe a me ke kūpaʻa ʻaʻahu kiʻekiʻe.Hoʻohana nui ia no ka hana ʻana i nā mea hana like ʻole, nā mea ʻokiʻoki, nā mold a me nā mea ana ana (e ʻike i ke kila kila).
Hoʻokaʻawale ʻia ke kila kila kila i 5 mau māka e like me ka ikaika o ke kila:
Q195, Q215, Q235, Q255, Q275
Hoʻokaʻawale ʻia kēlā me kēia brand i nā māka A, B, C, a me D ma muli o ke ʻano like ʻole.ʻEhā ʻano nui loa, a hoʻokahi wale nō;Eia kekahi, aia nā ʻokoʻa i ke ʻano deoxidation o ka hoʻoheheʻe kila.
Hōʻailona hana deoxygenation:
F – paila kila
b——he kila semi-pepehi
Z——pepehi kila
TZ——ke kila make kūikawā
Mea o ke kila poepoe: Q195, Q235, 10#, 20#, 35#, 45#, Q215, Q235, Q345, 12Cr1Mov, 15CrMo, 304, 316, 20Cr, 40Cr, 20CrGCMo, 45CrGCMo, 40CrGCMo, 35CrGCMo , 65Mn , 50Mn, 50Cr, 3Cr2W8V, 20CrMnTi, 5CrMnMo, etc.
