Q355 Chitoliro Chachitsulo Chotentha Chopanda Msokonezo

Q355 Yotentha Yokulungidwa Chitoliro Chopanda Chitsulo Chowonetsedwa

Kufotokozera Kwachidule:

Q355 zitsulo chitoliro ndi Chinese otsika aloyi mkulu mphamvu structural zitsulo chitoliro, amene m'malo Q345, kachulukidwe zakuthupi ndi 7.85 g/cm3.Malinga ndi GB/T 1591 -2018, Q355 ili ndi magawo atatu apamwamba: Q355B, Q355C ndi Q355D.

Chitoliro chachitsulo cha Q355 ndi aloyi otsika, chitsulo champhamvu kwambiri chomwe chimagwiritsidwa ntchito muzinthu zowotcherera zomwe zimathandizira kupsinjika ndi katundu wolemetsa.Q imatchula zokolola, pamene nambala 355 imasonyeza mphamvu zake zokolola.

Makhalidwe a Q355 Steel Pipe

Q355 zitsulo chitoliro ndi structural zitsulo ndi mphamvu zokolola za 345 MPa ndi kumakoka mphamvu 450 MPa.Ili ndi magwiridwe antchito owopsa komanso mphamvu zopondereza, zomwe zitha kugwiritsidwa ntchito popanga zombo zothamanga kwambiri zamagesi okhala ndi malita osakwana 500.Q355 ilinso ndi gawo loteteza la dzimbiri.

Kugwiritsa ntchito paipi yachitsulo ya Q355

Chitoliro chachitsulo cha Q355 chili ndi zida zabwino zamakina, kutsekemera kwakukulu, komanso kukana kwa dzimbiri.Itha kugwiritsidwa ntchito kupanga ndi kupanga akasinja osungira mafuta, zotengera zothamanga kwambiri, ma boilers, zombo, malo opangira magetsi, ndi zina zambiri zonyamula katundu wambiri.

Kukula: 34mm-610mm.

WT: 3.5mm-50mm

Maonekedwe: Chozungulira.

Mtundu wopanga: Kutentha kotentha kapena Kutentha kwambiri.

Utali: Utali umodzi mwachisawawa / Kawiri mwachisawawa kutalika kapena ngati kasitomala akufunadi kutalika kwake ndi 12m

Kuwongola

Pambuyo pa annealing, katunduyo amadutsa mu makina asanu ndi awiri owongoka kuti akwaniritse kuwongola koyenera kwa machubu.

Eddy panopa

Pambuyo kuwongola, chubu chilichonse chimadutsa pamakina amakono a eddy kuti azindikire ming'alu yapamtunda ndi zolakwika zina.Machubu okhawo omwe amadutsa eddy current ndi oyenera kutumizidwa kwa makasitomala.

Kumaliza

Chubu chilichonse chimapakidwa mafuta osagwirizana ndi dzimbiri kapena chopaka utoto kuti chitetezeke komanso kuti chisachite dzimbiri monga momwe makasitomala amafunira, machubu aliwonse amaphimbidwa ndi zipewa zapulasitiki kuti zisawonongeke podutsa, zolembera ndi zolemba zimayikidwa ndipo katundu wakonzeka kutumizidwa. .

Kugwiritsa ntchito
