Mbale Wotentha Wokulungidwa Wosapanga chitsulo
Pamafunika kupirira dzimbiri wa asidi oxalic, sulfuric asidi chitsulo sulphate, asidi nitric, nitric asidi hydrofluoric asidi, sulfuric asidi mkuwa sulphate, asidi phosphoric, asidi formic, asidi asidi ndi zidulo zina.Amagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala, chakudya, mankhwala, kupanga mapepala, mafuta, mphamvu za atomiki ndi mafakitale ena, komanso mbali zosiyanasiyana za nyumba, kitchenware, tableware, magalimoto ndi zipangizo zapakhomo.Pofuna kuonetsetsa kuti zipangizo zamakina monga mphamvu zokolola, mphamvu zowonongeka, kutambasula ndi kuuma kwa mbale zosiyanasiyana zosapanga dzimbiri zimakwaniritsa zofunikira, mbale zachitsulo ziyenera kuchitidwa ndi kutentha kwa kutentha monga annealing, chithandizo chamankhwala ndi chithandizo chaukalamba asanabadwe.
Chitsulo chosapanga dzimbiri mbale ali yosalala pamwamba, mkulu plasticity, kulimba ndi mphamvu makina, ndi kugonjetsedwa ndi dzimbiri asidi, mpweya wamchere, njira ndi TV zina.Ndi mtundu wa chitsulo cha alloy chomwe sichapafupi kuchita dzimbiri, koma sichikhala ndi dzimbiri.
Kukana kwa dzimbiri zitsulo zosapanga dzimbiri makamaka zimadalira kapangidwe kake ka aloyi (chromium, faifi tambala, titaniyamu, silicon, aluminiyamu, etc.) ndi kapangidwe mkati.Chromium imagwira ntchito yayikulu.Chromium imakhala ndi kukhazikika kwamankhwala, imatha kupanga filimu yokhazikika pamwamba pazitsulo, kudzipatula chitsulo kunja, kuteteza mbale yachitsulo ku okosijeni ndikuwonjezera kukana kwa dzimbiri kwa mbale yachitsulo.Pambuyo filimu ya passivation ikuwonongedwa, kukana kwa dzimbiri kumachepa.
Malingana ndi njira yopangira, pali mitundu iwiri ya kugudubuza kotentha ndi kuzizira, kuphatikizapo mbale yopyapyala yokhala ndi makulidwe a 0.5-4 mm ndi mbale yakuda ndi makulidwe a 4.5-35 mm.
Malinga ndi mawonekedwe a chitsulo kalasi, akhoza kugawidwa mu mitundu 5: austenite mtundu, austenite ferrite mtundu, ferrite mtundu, martensite mtundu ndi mpweya kuumitsa mtundu.
Mkulu wamphamvu zosapanga dzimbiri mbale ndi bwino dzimbiri kukana, kupinda processability ndi kulimba kwa mbali kuwotcherera, komanso masitampu processability wa mbali kuwotcherera ndi njira yake kupanga.Mwachindunji, mbale yachitsulo yosapanga dzimbiri yomwe ili ndi Si, Mn, P, s, Al ndi Ni yokhala ndi zofunikira zosakwana 0.02% za C, zosakwana 0.02% za N, zopitilira 11% za Cr ndi zosakwana 17%, ndi kukwaniritsa zofunikira za 12 ≤ Cr Mo 1.5si ≤ 17, 1 ≤ Ni 30 (cn) 0.5 (Mn Cu) ≤ 4, Cr 0.5 (Ni Cu) 3.3mo ≥ 16.0, 0.006 ≤ C0 n0 mpaka 3 ≤ 5 ~ 1250 ℃, ndiyeno kutentha mankhwala azichitika pa mlingo kuzirala oposa 1 ℃ / s.Mwanjira imeneyi, imatha kukhala mbale yachitsulo yosapanga dzimbiri yolimba kwambiri yokhala ndi martensite opitilira 12% ndi voliyumu, mphamvu yayikulu yopitilira 730mpa, kukana kwa dzimbiri ndi kupindika, komanso kulimba kwambiri kwa kutentha komwe kumakhudzidwa ndi kuwotcherera.Magwiridwe a stamping a ma welded amatha kusintha kwambiri pogwiritsa ntchito Mo, B, etc.
