Nws yuav siv sij hawm ntev npaum li cas rau lub rooj vuam 3D kom ruaj khov tom qab tau qib?

1. Tshaj tawm-txoj kev ncaj qis-kev ntxhov siab kub- nyem tempering
Yog hais tias tus txheej txheem tempering uas tuav ntawm 300℃rau 30 feeb yog ua tom qab straightening, feem ntau ntawm cov kev ntxhov siab nyob rau hauv induced los ntawm cov txheej txheem straightening yuav raug tshem tawm. Kev ruaj ntseg tag nrho tuaj yeem ua tiav tom qab lub sijhawm tuav ntawm 7 mus rau 15 hnub; natural aging on a flat, zoo-ventilated deg txaus.

2. Mechanical straightening nkaus xwb (tsis muaj kev ntxhov siab-relief tempering)
Txias straightening yam tsis muaj tempering tom ntej tawm residual internal stresses. Lub sijhawm laus ntawm 20 mus rau 30 hnub yuav tsum tau tso cai rau cov kev ntxhov siab no maj mam ploj mus thiab kom qhov tseeb qhov tseeb kom ruaj khov. Thaum ruaj khov, flatness yuav tsum tau rov- txheeb xyuas kom ntseeg tau tias tsis muaj qhov sib txawv ua ntej cov khoom siv tau muab tso rau hauv kev pabcuam.

3. Ua ke txhua yam thiab nplaim taws ncaj
Thaum kev ntxhov siab-relief tempering ua raws li kev sib koom ua ke, kev ruaj ntseg tag nrho feem ntau ua tiav hauv 10 mus rau 20 hnub. Txawm li cas los xij, yog tias qhov chaw cia khoom muaj qhov hloov pauv ntawm qhov kub thiab txias (piv txwv li, qhov ntsuas kub ntawm qhov ntsuas kub ntau tshaj 10 degree), nws raug nquahu kom ncua sij hawm ntev li 3 mus rau 5 hnub txhawm rau ua kom muaj kev ntxhov siab ntau dua.
