Product sumo:

① Iwo manhamba maviri ekutanga kwenhamba yesimbi anoratidza kabhoni yesimbi, ine avhareji kabhoni yezviuru zvishoma, senge 40Cr, 30CrMo alloy simbi pombi.

② Iwo makuru alloying zvinhu musimbi, kunze kwemamwe ma microalloying element, anowanzo kuratidzwa ne akati wandei muzana.Kana iyo yepakati alloy yemukati iri pasi pe1.5%, chete chiratidzo chechinhu chinowanzo kunyorwa munhamba yesimbi, asi kwete zvirimo.Nekudaro, muzviitiko zvakakosha, zviri nyore kuvhiringidza, iyo nhamba "1" inogona kunyorwa mushure mechiratidzo chechinhu, senge simbi nhamba "12CrMoV" uye "12Cr1MoV", iyo chromium yemukati ndeye 0.4-0.6%, uye iyo yekupedzisira ndeye 0.9-1.2%.Zvimwe zvese zvakafanana.Kana avhareji yealloying element yemukati ≥1.5%, ≥2.5%, ≥3.5%…… “, chiratidzo chechinhu chinofanira kumakwa mushure mezvirimo, chinogona kuratidzwa se 2, 3, 4…… Etc. Semuyenzaniso, 18Cr2Ni4WA.

③ Alloy zvinhu zvakaita sevanadium V, titanium Ti, aluminium AL, boron B uye isingawanzo pasi RE musimbi ndeye microalloying zvinhu.Kunyange zvazvo zvirimo zvakaderera zvikuru, zvinofanira kuramba zvichimakwa panhamba yesimbi.Semuenzaniso, mu20MnVB simbi.Vanadium ndeye 0.07-0.12% uye boron iri 0.001-0.005%.

④ "A" inofanira kuwedzerwa panoperera nhamba yesimbi yesimbi yepamusoro-giredhi kuti isiyanise kubva kune yakajairwa yemhando yepamusoro simbi.

⑤ Special chinangwa alloy structural simbi, simbi nhamba prefix (kana suffix) inomiririra chinangwa chechiratidzo chesimbi.Semuyenzaniso, iyo 30CrMnSi simbi inonyanyo shandiswa riveting screws inoratidzwa seML30CrMnSi.

Tekinoroji yekugadzira:

1. Kutenderedza kunopisa (extrusion seamless simbi pombi) : chubhu isina chinhu → kudziyisa → perforating → matatu-yakakwirira diagonal kukunguruka, kuenderera mberi kukunguruka kana extrusion → kukurura → saizi (kana kuderedza) → kutonhora → kutwasanudza → hydrostatic test (kana kuongorora) → kumaka → kuchengetedza

2. Pombi yesimbi inotonhorwa (yakakungurutswa) isina musono: chubhu yeround isina chinhu → kudziyisa → perforation → musoro → annealing → pickling → kuzora (copper plating) → yakawanda-ipfuura inotonhora kudhirowa (inotonhorera) → chubhu isina chinhu → kupisa kupisa → kutwasanudza → hydrostatic bvunzo (kuongorora) → kumaka → kuchengetedza
