1. Dab tsi yog qhov tseem ceeb txhais thiab cov yam ntxwv ntawm FH550 steel yeeb nkab?
FH550 yog f- qib ultra {2} high {3} High Heev Qib rau cov neeg ua haujlwm siab tshaj plaws rau kev ua haujlwm hauv Suav teb. Nws cov khoom tseem ceeb muaj xws li:
Paib lub zog ntau dua lossis sib npaug nrog 550 MPa, tensile muaj zog 670}}}, tsim tshwj xeeb rau cov khoom siv hnyav ultra siv;
- 60 Qeb Ultra {2} Qhov kev ua haujlwm qis hauv 42 4} Qhov kev xav tau ntawm cov huab cua tsawg hauv cov cheeb tsam Polar thiab ntau dua;
Ultra - lub zog siab thiab tawv tawv tau ua tiav los ntawm kev sib xyaw ua ke}}}}}}}}}}}} Quenching + Ob-theem tempering (DQ + Ltr) cov txheej txheem.
2. Lub ntsiab kev thov ntawm FH550 yog dab tsi? FH550 yog tsim tshwj xeeb rau ultra - cov khoom siv hnyav hauv cov chaw muaj ib puag ncig. Cov ntawv thov raug muaj xws li:
{-} Powered IceBreakers: Hulls thiab thauj cov kab laum nrog cov dej khov tuab ntau dua 3.5 meters;
Tag nrho - Oce Oce {{qhov tob manend submersibles: Cov khoom siv tseem ceeb rau kev siab siab txog 10,000 meters;
Polar tub rog engineering: Cov chaw ua haujlwm tshwj xeeb xws li nyob rau hauv -} ish missile silos thiab polar tua cov platform.
3. Dab tsi thev naus laus zis puas tau muab FH550 piv rau Eh550?
Kev yoog raws li cov chaw ib puag ncig zoo: kev cuam tshuam lub zog muaj 50% siab dua EH550 (-40 degree), thiab ndt kub tsawg dua lossis sib npaug ntawm -85 degree.
Alloy System Txhim Kho: NI cov ntsiab lus yog nce rau 2.2%- 2.8%, thiab tsis tshua muaj cov qoob loo nplej, txhim kho qis-kub ruaj khov los ntawm 40%.
Cov txheej txheem Innessation: Ultra -}}} {} Cov txheej txheem tshwj xeeb yuav tsum ua rau kev ua FH550 sai li cas?
Vuam Tshuab:
Qib tshwj xeeb f f vuam consumables (xws li AWS ES ES15018-G) yuav tsum tau siv, nrog preheat kub ntau dua los yog sib npaug ntawm 220 degree.
Electron nqaj vuam los yog laser - arc Hybrid Vuam yog ua haujlwm, nrog cua sov tawm ntawm 8 thiab 15 KJ / CM2.
Tsim txheej txheem: ua haujlwm txias yog txwv; Kev tsim kub (700-900 degree) lossis isothermal forging yog yuav tsum tau.
Tshaj tawm - Weld Kev Kho Mob: Txhua tus Welds xav tau ib qho kev ntxhov siab
5. Yuav ua li cas yog qhov kev ua tau zoo ntawm FH550 paub tseeb? Cov khoom tseem ceeb tshaj plaws yog dab tsi? Kev kuaj:
Tshuaj lom neeg tshuaj: C Tsawg dua li lossis nce sib npaug rau 0.007%, s tsawg dua 0.007%, s tsawg dua lossis sib npaug rau 5 ppm;
-60 Degree Test series: suav nrog cov kev cuam tshuam, Δ ntau dua lossis sib npaug rau 0.35 mm), thiab dwtt (sa ntau dua lossis sib npaug ntawm 88%);
Tsis - Kev sim:
100% muaj CT tag nrho - ntu seem rau kev tsis sib xws rau qhov tsis xws luag;
Neutron Diffraction Residual kev ntxhov siab kev ntxhov siab thiab 3D cov tshuab ntsuas kev tsom xam (EBSD).
