Wopanga Zitsulo Zogulitsa Zogulitsa
Tsatanetsatane
M'lifupi pepala ndi 500 ~ 1500 mm;Kukula kwa makulidwe ndi 600 ~ 3000 mm.Ma mbale woonda amagawidwa ndi mitundu yazitsulo, kuphatikizapo zitsulo wamba, zitsulo zamtengo wapatali, zitsulo za aloyi, zitsulo zamasika, zitsulo zosapanga dzimbiri, zitsulo zosapanga dzimbiri, zitsulo zosagwira kutentha, zitsulo zokhala ndi zitsulo, zitsulo za silicon ndi pepala loyera la mafakitale, etc. Malinga ndi akatswiri ntchito, pali ng'oma mafuta ndi bolodi, enamel ndi bolodi, zipolopolo ndi bolodi, etc. Malinga ndi mfundo pamwamba ❖ kuyanika, pali kanasonkhezereka pepala, mbale malata, mbale kutsogolera, pulasitiki gulu zitsulo mbale.Kutentha kwakukulu, kuthamanga kwambiri, kutentha kochepa, kukana kwa dzimbiri.
Zitsulo zokhuthala zimakhala zamtundu wofanana ndi zoonda.M'mbali zonse, kuwonjezera pa mbale ya mlatho, mbale zowotchera, zitsulo zamagalimoto, mbale yachitsulo yoponderezedwa ndi zitsulo zamitundu yambirimbiri, zitsulo zamitundu yosiyanasiyana, zitsulo zamitundu ina monga zitsulo zamagalimoto (2.5 ~ 10 mm wandiweyani). ), mbale yokongoletsera (2.5 ~ 8 mm wandiweyani), chitsulo chosapanga dzimbiri, chitsulo chosagwira kutentha ndi mitundu ina yokhala ndi mtanda woonda.
Kuonjezera apo, mbale yachitsulo ndi zinthu zinati, sizitsulo zonse zomwe zimakhala zofanana, zinthu sizili zofanana, malo omwe zitsulo zimagwiritsidwa ntchito, sizili zofanana.
Gulu la Alloy Steel
Malinga ndi zomwe zili mu alloying element, zitha kugawidwa m'magulu awiri:Chitsulo chochepa cha alloy (chinthu chonse cha alloy zosakwana 5%), Chitsulo cham'katikati (chinthu chonse cha alloy 5% -10%), Chitsulo chachikulu chachitsulo (chinthu chonse chophatikiza> 10%).
Malinga ndi zinthu zazikuluzikulu za alloying, zimagawidwa kukhala:Chromium steel (CR-Fe-C) Chrome-Nickel steel (CR-Ni-Fe-C), Manganese (Mn - Fe - C), Silicon Manganese steel (Si-Mn-Fe-C).
Malinga ndi mawonekedwe a normalizing kapena as-cast of samples ang'onoang'ono, amatha kugawidwa mu:Pearlitic zitsulo, Martensitic zitsulo, Ferritic chitsulo, Austenitic chitsulo, Ledeburite zitsulo.
Kuperewera kwa Carbon Steel
(1) Kusalimba mtima.Ambiri, pazipita quenching awiri a mpweya zitsulo quenching madzi ndi 10mm-20mm okha.
(2) Mphamvu zochepa komanso zomangira.Mwachitsanzo, σ S wa chitsulo wamba mpweya Q235 chitsulo ndi 235MPa, pamene σ S otsika aloyi structural chitsulo 16Mn ndi kuposa 360MPa.The σ S / σ B ya 40 zitsulo ndi 0,43 yokha, yomwe ili yotsika kwambiri kuposa yachitsulo cha alloy.
(3) Kusakhazikika kwa mtima.Chifukwa cha kusasunthika kosasunthika, chitsulo cha carbon mu quenching ndi tempering chithandizo, pofuna kuonetsetsa mphamvu zapamwamba zogwiritsira ntchito kutentha kwapansi, kuti kulimba kwachitsulo kumakhala kochepa;Pofuna kuonetsetsa kulimba bwino, mphamvu ya kutentha kwambiri kutentha ndi otsika, kotero mabuku mawotchi zimatha mpweya zitsulo si mkulu.
(4) Sangathe kukwaniritsa zofunikira za ntchito yapadera.Chitsulo cha carbon mu kukana makutidwe ndi okosijeni, kukana kwa dzimbiri, kukana kutentha, kukana kutentha pang'ono, kukana kuvala ndi ma elekitirodi apadera ndi zinthu zina nthawi zambiri zimakhala zosauka, sizingakwaniritse zosowa zapadera.
