Cov Zog Loj Q800D Almloy Hlau Hlau Phaj

 

 

1. Cov Lus Qhia Txheej Txheem

Q800D yog lub siab-muaj zog qis-alloy (hsla) tus qauv hlau nrog cov kws kho tshuab hlau uas tau, Weldability, thiab kev cuam tshuam tawv. Nws cov khoom siv tshuaj lom neeg raug suav nrog:

Cov pa roj carbon (c):{{{{{{0}}}}. 05-0.12% - txhim kho Veldability thaum tuav kom muaj Weldability.

Manganese (MN):1. {{{{{}} - 1.60% - txhim kho cov kev nyuaj thiab tensile lub zog.

Silicon (si):{{{{0}}}}. 10-0.50% - Tau txais txiaj ntsig kom tau txais deoxidation thiab lub zog.

Phosphorus (p):Tsawg dua los yog sib npaug rau 0. 020% - tswj hwm kom txo qis brittleness.

Sulphur (s):Tsawg dua li lossis sib npaug rau {0. 010% - txwv kom txhim kho kev sib kho thiab tawv.

Microalloying ntsiab (NB, V, TI):{{{{{0}}}}}

Boron (b):Cov nyiaj feem pua ​​(xaiv tau) - txhim kho cov neeg muaj kev nyuaj.

2. Cov yam ntxwv tseem ceeb

Paib lub zog:Ntau dua los yog sib npaug rau 800 MPa

Lub zog tensile:850-1000 MPa

Elongation:Ntau dua los yog sib npaug rau 14%

Cuam Tshuam Toansness (ntawm -20 degree):Ntau dua los yog sib npaug rau 27 j

Zoo Weldability(Preheating tej zaum yuav tsum tau kom tuab daim hlau.)                   

3. Daim ntawv thov cov lus qhia

Q800D tau siv dav hauv cov ntawv thov tsim qauv, suav nrog:

Cov Machinery hnyav(Cranes, cov khoom siv mining)

Siv & Txuas Hniav(High-load-bearing Cheebtsam)

Kev mus(Cov tsheb thauj khoom thav duab, cov shocks)

Offshore Cov Qauv(Cua turbine yees, platforms)

Defense & Aerospace(Cov tsheb muaj riam phom, kev txhawb nqa qauv)

Cov Lus Taw Qhia:

Tej:Ntshav, laser, lossis kev txiav dej txiav yog nyiam rau qhov tseeb.

Vuam:Siv cov hluav taws xob tsawg-hydrogen) (piv txwv li, e11018) nrog kom zoo preheating (100-150 degree rau cov kab tuab).

Txoj kev sib sau:Txias kev ua yog ua tau tab sis yuav xav tau anealing rau cov duab nyuaj.

Kev Kho Cua Sov:Quenching & Tempering (Q & T) Ua kom zoo-kev sib npaug.

4. Qhov zoo tshaj cov hlau sib xyaw

Ntau lub zog-rau-qhov hnyav piv txwvtxo cov khoom siv.

Superior qaug zogRau lub sijhawm ntev ntev.

Eco-phooj ywg(Qis dua cov khau looj tes rau kev txo cov qauv hauv cov qauv).
