35CrMo paipa maitai koranu
Whakaahuatanga Poto:
Whakatakotoranga whakaputa:
Te diameter o waho o te paipa maitai 20-426
Steel putorino taiepa matotoru o 20-426
Hua whakataki:
Hei tauira, 40Cr.(Ko te ihirangi waro o 35CrMo koranu maitai putorino ko 0.32~0.40, silicon 0.17~0.37, konupora 0.40~0.70, molybdenum 0.15~0.25, chromium 0.80~1.10)
② Ko nga huānga koranu matua i roto i te rino, haunga etahi huānga microalloying, he maha nga ōrau e whakaatuhia ana.Ina he iti iho i te 1.5% te ihirangi koranu toharite, ko te tohu huānga anake e tohuhia ana i roto i te tau rino, engari kaua ko te ihirangi.Heoi, i roto i nga keehi motuhake, he ngawari ki te pohehe, ko te nama "1" ka taea te tohu i muri i te tohu huānga, penei i te nama rino "12CrMoV" me "12Cr1MoV", ko te ihirangi chromium o mua ko 0.4-0.6%, a ko te mea o muri ko 0.9-1.2%.He rite tonu nga mea katoa.Ina ≥1.5%, ≥2.5%, ≥3.5%…… “, me tohu te tohu huānga i muri i te ihirangi, ka taea te whakaatu hei 2, 3, 4…… Etc. Hei tauira, 18Cr2Ni4WA.
③ Ko nga mea whakauru penei i te vanadium V, te titanium Ti, te konumohe AL, te boron B me te whenua onge RE i roto i te maitai no nga huānga microalloying.Ahakoa he iti rawa nga korero, me tohu tonu ki te nama rino.Hei tauira, i roto i te 20MnVB maitai.Ko te Vanadium te 0.07-0.12% me te boron he 0.001-0.005%.
④ Me tapiri te "A" ki te mutunga o te nama rino o te rino teitei hei wehe ke i te maitai o te kounga teitei.
⑤ Ko te koranu rino hanga motuhake, ko te kumara tau rino (te kumara ranei) hei tohu mo te tohu rino.Hei tauira, ko te maitai 30CrMnSi i whakamahia motuhake mo te riveting screws ka kiia ko ML30CrMnSi.
Ko te ngongo Alloy me te ngongo korekore he hononga me nga rereketanga, kaore e taea te pohehe.
Ko te putorino Alloy he putorino rino i runga i nga mea hanga (ara, rauemi) hei tautuhi, i te mea e kii ana te ingoa he mea hanga ki te putorino koranu;Na te putorino tui he putorino maitai i roto i runga i te tukanga whakaputa (kore) ki te tautuhi, rerekē i te putorino tui he paipa paiherea, tae atu ki te tui tika putorino paiherea me te putorino tōrino.
Hangarau hanga:
1. Te okeoke wera (te tangohanga paipa maitai kore) : ngongo porowhita → whakawera → perforating → toru-te teitei o te hurihanga hauroki, te huri haere tonu, te tangohanga ranei → te tihorea → te rahi (te whakaiti ranei) → te whakamahana → te whakamahana → te whakamatautau hydrostatic (te tirotiro ranei) → te tohu → rokiroki
2. Pupa maitai tuitui (whakatakahia) matao: ngongo porowhita → whakawera → perforation → pane → annealing → pickling → hinu (whakakikorua parahi) → tuhi matao-maha (rere makariri) → ngongo parakore → maimoatanga wera → whakatikatika → whakamātautau hydrostatic (tirotiro) → tohu → rokiroki
