30CrMo aloyi zitsulo chitoliro

Kufotokozera Kwachidule:

Kapangidwe kake:

Akunja awiri a zitsulo chitoliro 20-426

Zitsulo chitoliro khoma makulidwe a 20-426

Chidziwitso cha malonda:

① Ma manambala awiri omwe ali koyambirira kwa chitsulo akuwonetsa zomwe zili mu chitsulo, zomwe zimakhala ndi kaboni pafupifupi zikwi zingapo, monga 40Cr, 30CrMo alloy steel pipe.

② Zinthu zazikulu zophatikizira muzitsulo, kupatula ma microalloying ena, nthawi zambiri zimawonetsedwa ndi maperesenti angapo.Pamene pafupifupi aloyi zili zosakwana 1.5%, chizindikiro chokhacho chimakhala ndi nambala yachitsulo, koma osati zomwe zili.Komabe, muzochitika zapadera, ndizosavuta kusokoneza, nambala "1" ikhoza kulembedwa pambuyo pa chizindikiro cha chinthu, monga nambala yachitsulo "12CrMoV" ndi "12Cr1MoV", zomwe zili mu chromium zakale ndi 0.4-0.6%, ndipo chakumapeto ndi 0.9-1.2%.Zina zonse ndi zofanana.Pamene pafupifupi alloying element zili ≥1.5%, ≥2.5%, ≥3.5%…… “, chinthu chizindikiro ayenera chizindikiro pambuyo zimene zili, akhoza kufotokozedwa ngati 2, 3, 4…… Etc. Mwachitsanzo, 18Cr2Ni4WA.

③ Zinthu za aloyi monga vanadium V, titaniyamu Ti, aluminiyamu AL, boron B ndi osowa dziko lapansi RE muzitsulo ndizinthu za microalloying.Ngakhale zili zochepa kwambiri, ziyenera kulembedwabe pa nambala yachitsulo.Mwachitsanzo, mu 20MnVB zitsulo.Vanadium ndi 0.07-0.12% ndipo boron ndi 0.001-0.005%.

④ "A" iyenera kuwonjezeredwa kumapeto kwa chitsulo chachitsulo chapamwamba kwambiri kuti chisiyanitse ndi chitsulo chapamwamba kwambiri.

⑤ Cholinga chapadera cha alloy structural steel, prefix nambala yachitsulo (kapena suffix) imayimira cholinga cha chizindikiro chachitsulo.Mwachitsanzo, chitsulo cha 30CrMnSi chomwe chimagwiritsidwa ntchito makamaka popangira zomangira chimawonetsedwa ngati ML30CrMnSi.

Ukadaulo wopanga:

1. Kugudubuzika kotentha (chitoliro chopanda msokonezo chachitsulo) : chubu chozungulira chilibe kanthu → kutenthetsa → chobowoleza → kugudubuzika kotalikirana katatu, kugudubuzika kosalekeza kapena kutulutsa → kuvula → kukula (kapena kuchepetsa) → kuzirala → kuwongola → kuyesa kwa hydrostatic (kapena kuyang'ana) → chizindikiro → yosungirako

2. Chitoliro chachitsulo chozizira (chogudubuzika) chopanda msoko: chubu chozungulira chilibe kanthu → kutenthetsa → kuboola → mutu → kung'amba → pickling → kudzola mafuta (kuyika mkuwa) → zojambula zozizira zambiri (zozizira) → chubu chopanda kanthu → chithandizo cha kutentha → kuwongola → kuyesa kwa hydrostatic (kuwunika) → kuyika chizindikiro → kusungirako
