Q500NH Weathering Steelgen yonPi wo tandans defòme pandan pwosesisKonpare ak asye modere akòz gwo fòs li yo (500 MPa sede) ak pi ba duktilite, men deformation ka kontwole ak teknik apwopriye. Isit la nan yon gid kout:
Poukisa li tendans deformation?
Gwo fòs rendement: Mande pou plis fòs yo pliye/koupe, ogmante estrès rezidyèl.
Pi ba elongasyon(~ 18% vs . 23% nan Q235 asye) diminye kapasite deformation plastik.
Ki jan yo kontwole deformation?
1. Koupe & D '
Sèvi ak zouti rijid: Lam carbure oswa lazè/plasma koupe pou misyon pou minimize deformation chalè.
Kranpon byen fèm: Anpeche Vibration-induit deformation.
2. Bending & Forming
Frèt koube: Limite a reyon pi gran pase oswa egal a2 × epesè(egzanp, 20mm pou plak 10mm).
Cho koube(600-800 degre) pou reyon sere, ki te swiv pa refwadisman ralanti.
3. soude
Chofe a 150-200 degreepi sèvi ak elektwòd ba-idwojèn diminye estrès kontraksyon.
Altène sekans soudePou balanse opinyon chalè.
4. Post-pwosesis
Soulajman estrès: Chalè a 250-300 degre (si presizyon se kritik).
Redaksyon mekanik: Sèvi ak près idwolik, pa rakle.
