Njira zosiyanasiyana zimatha kupanga mbiri zachitsulo chosapanga dzimbiri, zonse zomwe zimapereka mapindu osiyanasiyana. Hot adagulung'undisa mbiri ali ndi makhalidwe enieni komanso.
Jindalai Steel Group ndi katswiri pa mbiri yotentha komanso kugudubuza kozizira kwa mbiri yapadera muzitsulo ndi zitsulo zosapanga dzimbiri. Tumizani kufunsa kwanu ndipo tidzakhala okondwa kukufunsani mwaukadaulo.
Kutulutsa mbiri kumatha kuchitika pa kutentha kwambiri (kutentha kotentha) kapena kutentha kwachipinda (kuzizira kozizira). Kutentha kumakhudza kwambiri zotsatira zake. Ndi matekinoloje onse opanga, ndizotheka kupanga mbiri yotentha kapena mbiri yoziziritsa muzitsulo zosapanga dzimbiri. Komabe, mawonekedwe a njira zonsezi amasonyeza kusiyana kosiyana.
Mbiri Zotentha Zotentha - Chitsulo Chopanda Chopanda Chikatentha
Kutentha kwa magawo ndiukadaulo wopindulitsa kwambiri wopanga mipiringidzo yayitali. Chigayocho chikakhazikitsidwa ndikukonzekera kupanga, chikhoza kutentha mbiri yakale kwambiri ndi zokolola zambiri. Nthawi zambiri, kutentha kumakwera pamwamba pa 1.100 digiri Celsius. Chifukwa chake ma billet kapena maluwa amachitidwe achikhalidwe "oyimitsa-yimitsidwa" -njira yopangira kapena ndodo zamawaya panjira "yosatha" zimatenthetsa mpaka pano. Zoyikapo zingapo zimapundula pulasitiki. Ma geometry ndi kutalika kwa mbiri yofunidwa yomalizidwa yotentha zimatsimikizira kukula ndi kulemera kwa zopangira.
Hot rolling ndi njira yapamwamba yopangira zinthu zambiri zazitali. Pokhapokha mwa kulondola ndi kutsirizitsa pamwamba, malire ayenera kuvomerezedwa.
Mbiri Yozizira Yozizira ndi Makhalidwe Awo
Zopangira zoziziritsa kuzizira ndi waya ndodo, yomwe ndi chinthu chomaliza. The awiri a ndodo zimadaliranso pa mtanda gawo la chomaliza mankhwala. Mofanana ndi kutentha kosatha, kupukuta kozizira kumakhalanso njira yopitilira, koma kutentha. Makina opanga amatsogolera waya kudzera m'malo osiyanasiyana motero amapanga mawonekedwe omwe amafunidwa ndi ma pass ambiri. Njirayi imachepetsa njere yachitsulo, zinthu zimakhala zolimba komanso pamwamba pake zimakhala zosalala komanso zonyezimira.
Kwa ma profayilo ovuta kwambiri, kugudubuza kangapo kungakhale kofunikira. Pamenepa, tikuyenera kutsekereza mbiriyo tisanayigulitsenso.
Tekinoloje iyi imalola kupanga ma profaili okhala ndi kulolerana kolimba. Ndi njira yabwino yopanga kupanga mbiri zazing'ono mpaka zapakatikati zozizira zapadera muzitsulo zosapanga dzimbiri.
Matekinoloje onsewa ali ndi mawonekedwe ake enieni komanso zabwino ndi zoyipa zake:
| Kuthamanga kotentha | Kuzizira kozizira | |
| Kuchita bwino | Wapamwamba kwambiri | Wapamwamba kwambiri |
| Magawo osiyanasiyana | Wapamwamba kwambiri | Wapamwamba kwambiri |
| Dimensional range | Wapamwamba kwambiri | Zochepa |
| Mtundu wazinthu | Wapamwamba kwambiri | Wapamwamba |
| Kutalika kwa bar | Muutali wokhazikika komanso mumakoyilo omwe amapezeka | Muutali wokhazikika komanso mumakoyilo omwe amapezeka |
| Kuchuluka kochepa | Wapamwamba | Zochepa |
| Kupanga ndalama | Wapamwamba kwambiri | Wapamwamba |
| Nthawi zotumizira | 3-4 miyezi | 3-4 miyezi |
| Kukula kwa malo | Ndi yayikulu kwambiri, mpaka 1 kilomita kutalika | Zochepa |
| Kulondola kwa dimension | Zochepa | Wapamwamba kwambiri |
| Ubwino wapamwamba | Zovuta | Zabwino kwambiri |
| Mtengo wa mbiri | Zotsika mpaka zapakati | Mtengo wapakati mpaka wapamwamba |
Magiredi Osiyanasiyana a Zitsulo Zosapanga dzimbiri za Mbiri Zowotcha komanso Mbiri Zozizira
Zodziwika bwino za austenitic zosapanga dzimbiri kalasi 304, motsatana 304L, komanso 316 kapena 316L ndi 316Ti ndizoyenera kupanga magawo otentha kapena ozizira. Izi zimateteza kupezeka kwa mbiri yachitsulo chosapanga dzimbiri pamsika. Zina mwazitsulo zosapanga dzimbiri zimataya ubwino wake zikatenthedwa ndipo chomalizacho chikhoza kukhala ndi zina zosafunikira. Zida zina zimatha kukhala zolimba komanso zolimba, chifukwa chake kuzizira kwamakina pogudubuzika kutentha sikungatheke.
