Tatumira 321 simbi isina ngura 1*1220*2440 kune mutengi wedu anobva kuUAE

Zvivakwa zveHemical

Simbi isingatsvinyike ye321 isimbi isingatsvinyike yakagadzirwa netitanium (yakafanana ne304 asi ine titanium yakawedzerwa kudzivirira kunaya kwe chromium carbide). Inopa simba rakanaka rekudzivirira kupisa kwakanyanya uye kudzivirira ngura pakati pegranular.

Kuumbwa Kwemakemikari Kwakajairika (%):

Chinhu Kuumbwa

Chromium (Cr) 17.0 – 19.0

Nickel (Ni) 9.0 – 12.0

Kabhoni (C) ≤0.08

Manganese (Mn) ≤2.0

Silikoni (Si) ≤1.0

Phosphorus (P) ≤0.045

Sarufa (S) ≤0.03

Titanium (Ti) ≥5×C (zvishoma 0.4%)

Simbi (Fe) Kuenzana

Zvinhu Zvikuru

✔Kugadzikana kwekupisa kwakanyanya (kusvika 800-900)°C)

✔Inodzivirira kunaya kwemvura yekabhoni (sensitization) panguva yekunamira

✔Kudzivirira kuoxidation uye ngura zvakanaka (zviri nani pane 304 mune dzimwe nzvimbo)

Mashandisirwo

Nekuda kwekudzivirira kupisa kwayo uye kugona kwayo kupinza, simbi isina ngura ye321 inoshandiswa zvakanyanya mu:

Zvikamu zveNdege neJet Engine (masisitimu eutsi, makamuri ekupisa)

Midziyo yeMakemikoro nePetrokemikari (zvinochinja-chinja kupisa, midziyo yekumanikidza)

Mapaipi & Mabhoyira Anopisa Zvakanyanya (kugadzikana kwekupisa)

Masisitimu eMotokari eKubudisa Matumbu (mafold, macatalytic converters)

Kugadzira Chikafu & Midziyo Yemishonga (kana zvichidikanwa kusona)

Kurapa Kupisa & Zvikamu zveVira (nekuda kwekusagadzikana kweokisijeni)

Magadzirirwo & Mafomu

Simbi isina ngura ye321 inowanikwa mu:

1. Ndiro/Pepa

Sei Uchifanira Kusarudza Simbi Isina Zvingasvibirwa 321?

✅Kushanda kwepamusoro-soro pakupisa kwepamusoro (vs. 304/316)

✅Kuderedzwa kwenjodzi yekuora kwepakati pegranular mushure mekunamira

✅Inoshandiswa zvakanyanya mumaindasitiri emuchadenga, emotokari, uye emakemikari
