China ozizira adagulung'undisa zitsulo koyilo DC01 DC03 DC04 DC06 Wopanga ndi katundu | Ruyi
Ndi ntchito yabwino yojambulira ndi kuwotcherera komanso yolondola kwambiri, mbale zachitsulo zokhala ndi mpweya wochepa kwambiri komanso zotsika kwambiri za carbon zoperekedwa ndi Mittel zagwiritsidwa ntchito kwambiri popanga zida zosiyanasiyana zamagalimoto. Pokhala ndi ductility, DC04(St14, St15) mbale zachitsulo zokhala ndi kaboni wochepa kwambiri ndi ultra-low carbon automotive steel plates ndizoyenera kupanga, kupindika kapena kuwotcherera mosavuta.
DC04(St14, St15) makina otsika a carbon ndi otsika kwambiri a carbon automotive zitsulo ndi magwiridwe antchito:
Chitsulo kalasi | Zokolola mphamvu MPa | Tensile mphamvu Mpa ≥ | Pambuyo Pakutha Kutalikirako (L0=80mm, b=20mm)%≥ | rb, c ≥ | nb, c ≥ | |||
Mwadzina Makulidwe mm | ||||||||
<; 0.70 | 0.70~<;1.0 | 1.0~<;1.6 | ≥1.6 | |||||
DC04(St14, St15) | 120-210 | 270 | 36 | 38 | 39 | 40 | 1.5 | 0.18 |
kutenga RP0.2 ngati zokolola zosadziwika bwino, apo ayi ReL.
c r=(r90+2r45+r0)/4; n= (n90 +2n45+n0)/4.
DC04(St14, St15) makulidwe a carbon otsika komanso otsika kwambiri a carbon automotive steel plates:
Mwadzina makulidwe: 0,30mm ~ 0.35mm, m'lifupi mwadzina: 700mm ~ 1850mm.
DC04(St14, St15) carbon low ndi Ultra-low carbon automotive steel stisile strain mark:
Ndizotsimikizika kuti palibe kupsinjika kwachitsulo komwe kumachitika pazitsulo zazitsulo ndi zomangira pakugwiritsa ntchito mkati mwa miyezi 6 zitapangidwa komanso ngati kutentha kwachipinda.
DC04(St14, St15) mpweya wotsika kwambiri komanso chitsulo chotsika kwambiri cha carbon automotive zitsulo:
Gulu | Kodi No. | Mawonekedwe |
Pafupifupi apamwamba amamaliza pamwamba | FB(O3) | Zimaloledwa kukhalapo pang'ono zolakwika zomwe sizingakhudze kupanga ndi zokutira & zomatira zomatira monga kukanda pang'ono, mawonekedwe, dzenje, chizindikiro chopukutira ndi utoto wa okosijeni. |
Malo omaliza apamwamba | FC(O4) | Mbali imodzi yamtundu wabwino ilibe chilema chilichonse chowoneka ndipo mbali inayo iyenera kukwaniritsa zofunikira za FB osachepera. |
Kopitilira muyeso wapamwamba kumaliza pamwamba | FD(O5) | Mbali imodzi yamtundu wabwino ilibe chilema chilichonse, chomwe ndi mawonekedwe amtundu pambuyo pojambula kapena galvanizing yamagetsi sichikhudzidwa, ndipo mbali inayo iyenera kufikira zofunikira za FB osachepera. |
