Njira Zopangira

(1)Njira yosungunula zitsulo
Chitsulo cha GB 5310 20MnG chidzasungunuka ndi ng'anjo yamagetsi kuphatikiza kuyeretsa ng'anjo, chosinthira okosijeni kuphatikiza kuyeretsa ng'anjo kapena njira ya electroslag remelting.

(2) Njira zopangira ndi zofunikira pazosowa za chubu
Chubu chopanda kanthu chimatha kupangidwa ndikuponyedwa mosalekeza, kuponyera kufa kapena kugudubuza kotentha (kufota).

(3) Kupanga njira yachitsulo chubu
Machubu achitsulo a GB 5310 20MnG adzapangidwa ndi kugudubuza kotentha (kutulutsa, kukulitsa) kapena kujambula kozizira (kugudubuza).

Kugwiritsa ntchito

Amagwiritsidwa Ntchito Kwambiri Kupanga Zitsulo Zapamwamba Za Carbon Structural Steel, Alloy Structural Steel Ndi Mapaipi Azitsulo Osatentha Opanda Kutentha Osasunthika Pakupanikizika Kwambiri Komanso Pamwamba pa Mapaipi Owotchera a nthunzi.

Amagwiritsidwa Ntchito Kwambiri Pakuthamanga Kwambiri Ndi Kutentha Kwambiri Kwa Boiler (Superheater Tube, Reheater Tube, Air Guide chubu, Main Steam chube For High And Ultra High Pressure Boilers).Pansi pa Kuchita Kwa Gasi Wotentha Kwambiri Ndi Mpweya wa Madzi, chubu Idzatulutsa Oxidize Ndi Kuwononga.Ndikofunikira Kuti Chitoliro Chachitsulo Chikhale Chokhazikika Kwambiri, Kukaniza Kwambiri Kumakutidwe ndi Oxidation Ndi Kuwonongeka, Ndi Kukhazikika Kwamapangidwe Abwino.

Main Grade

Kalasi Yazitsulo Zapamwamba Zapamwamba za Carbon: 20g, 20mng, 25mng
Kalasi ya Aloyi Structural Steel: 15mog, 20mog, 12crmog, 15crmog, 12cr2mog, 12crmovg, 12cr3movsitib, Etc
Gulu Lazitsulo Zosagwira Kutentha: 1cr18ni9 1cr18ni11nb

Utali:
Utali Wamapaipi Achitsulo Ndi 4 000 Mm ~ 12 000 Mm.Pambuyo Kukambirana Pakati pa Wopereka ndi Wogula, Ndi Kudzaza Mgwirizanowu, Ikhoza Kuperekedwa Mapaipi Achitsulo Ndi Utali Wautali Kuposa 12 000 Mm Kapena Wamfupi Kuposa I 000 Mm Koma Osachepera 3 000 Mm;Utali Waufupi Nambala Ya Mipopi Yachitsulo Ochepera 4,000 Mamilimita Koma Osaposa 3,000 Mm Sidzapitirira 5% Pa Chiwerengero Cha Mipaipi Yachitsulo Yonse Yoperekedwa.

Kulemera kwake:
Chitoliro Chachitsulo Chikaperekedwa Molingana ndi Diameter Ya Kunja Kwadzina Ndi Kukula Kwa Khoma Mwadzina Kapena Diameter Yam'kati Mwadzina Ndi Makulidwe Apakhoma Mwadzina, Chitoliro Chachitsulo Chimaperekedwa Molingana ndi Kulemera Kwenieni.Itha Kuperekedwanso Molingana ndi Theoretical Weight.
Pamene Chitoliro Chachitsulo Chimaperekedwa Molingana ndi Mzere Wakunja Wakunja Ndi Kuchepa Kwa Khoma, Chitoliro Chachitsulo Chimaperekedwa Molingana ndi Kulemera Kweniyeni;The Supply And Demand Parties Negotiate.Ndipo Izo zikusonyezedwa mu Contract.Chitoliro Chachitsulo Chikhoza Kuperekedwanso Molingana ndi Theoretical Weight.

Kulekerera Kulemera:
Malinga ndi Zofunikira za Wogula, Pambuyo Pakambilana Pakati Pa Wopereka Ndi Wogula, Ndipo Mumgwirizano, Kupatuka Kwapakati Pa Kulemera Kweniweni Ndi Kulemera Kwachidziwitso Kwa Pipe Yachitsulo Yotumizira Kudzakwaniritsa Zofunikira Izi:
A) Chitoliro Chimodzi Chokha: ± 10%;
B) Gulu Lililonse La Mapaipi Achitsulo Osachepera 10 T: ± 7.5%.

Chofunikira Choyesa

Mayeso a Hydraustatic:
Chitoliro Chachitsulo Chiyenera Kuyesedwa Hydraulically Mmodzi Ndi Mmodzi.Kuthamanga Kwambiri Kwambiri Ndi 20 MPa.Pansi pa Kupanikizika kwa Mayesero, Nthawi Yokhazikika Iyenera Kusachepera 10 S, Ndipo Chitoliro Chachitsulo Siyenera Kutayikira.
Pambuyo Wogwiritsa Ntchito Avomera, Mayeso a Hydraulic Atha Kusinthidwa Ndi Mayeso a Eddy Panopa Kapena Mayeso a Magnetic Flux Leakage.

Mayeso Osawononga:
Mipope Yomwe Imafunika Kuyang'ana Kwambiri Iyenera Kuyang'aniridwa Mmodzi Ndi Mmodzi.Pambuyo Kukambitsirana Kumafuna Chivomerezo cha Phwando Ndipo Kufotokozedwa Mumgwirizanowu, Mayeso Ena Osawononga Akhoza Kuwonjezedwa.

Mayeso a Flattening:
Machubu Okhala Ndi Diameter Yakunja Yoposa 22 Mm Adzayesedwa Kusanja.Palibe Delamination Yowoneka, Mawanga Oyera, Kapena Zonyansa Zomwe Ziyenera Kuchitika Pakuyesa Konse.

Kuyesa kwa Flaring:
Malinga ndi Zofunikira za Wogula Ndipo Zanenedwa Mgwirizanowu, Chitoliro Chachitsulo Chokhala Ndi Diameter Yakunja ≤76mm Ndi Makulidwe Akhoma ≤8mm Itha Kuyesedwa Kuphulika.Kuyesaku Kudachitika Pakutentha Kwazipinda Ndi Taper Ya 60 °.Pambuyo Kuwotcha, Kuwotcha Kwa Diameter Yakunja Kuyenera Kukwaniritsa Zofunikira Patebulo Lotsatirali, Ndipo Zoyeserera Siziyenera Kuwonetsa Ming'alu Kapena Kung'ambika.
