JIS Txheem SM490 Hlau Phiaj Hlau

Cov Lus Qhia Yooj Yim

Cov Qauv Txheej Txheem: Teev nyob rau hauv Japanese muaj kev muaj txoj haujlwmJIS G3106, covering hot-rolled high-strength structural steel plates for applications requiring high strength and good weldability, such as construction, bridges, and machinery manufacturing.

Tis npe txoj cai:

Sw: Cov tsiaj ntawv luv rau "Cov Qauv Hlau Rau Nruab Nrab Lub Zog" (siv cov qauv txheem, nruab nrab tensile qib).

490: Qhia txog qhov tsawg kawg tensile lub zog ntawm490 MPaRau cov phaj nrog tuab tsawg dua lossis sib npaug rau 16 hli.

 

Kev qhia tshwj xeeb peb muab:

Qhov tuab	3-200 hli
Qhov dav	1500-4000 hli
Qho ntev	5000-15000 hli

 

Cov txheej txheem raug

Kub Rolling:

Tsim los ntawm kev kub siab-kub yob kom ua tiav cov khoom siv microstration micructure thiab ruaj khov kho cov khoom.

Haum rau cov phiaj loj-thickness; raug nqi-ua tau zoo thiab txuag tau.

Norming (yeem):

Cov cua sov ua raws cua txias rau cov qauv grade, txhim kho kev ua kom nruj thiab cov txheej txheem rau cov ntawv thov cov ntawv thov siab.

 

Vuam thiab machining kev ua yeeb yam

Hwj txwv:

Tsawg cov pa roj carbon sib npaug (Ce tsawg dua lossis sib npaug rau 0. 45%), ua kom cov vuam hlau (arc welielded vuam).

Preheating feem ntau tsis tsim nyog rau nyias daim hlau, tab sis cov phiaj tuab yuav xav kom tiv thaiv kom tsis txhob muaj kev tiv thaiv.

Txiav thiab sib sau:

Txhawb cov nplaim taws txiav, ntshav txiav, thiab tshuab tshuab tshuab.

Zam kev ua cua sov ntau dhau los tiv thaiv kev tawm tsam kev tawm tsam ntawm cov khoom siv neeg kho tshuab.
