Thaum txias dabtsiQ500NH Wights Hlau, cov kev ceev faj hauv qab no yog qhov tseem ceeb los tswj cov qauv txheej txheem thiab corrosion tsis kam:
1. Khoom npaj npaj
Kev Soj Ntsuam:
Txheeb xyuas cov chaw uas twb muaj lawm (tawg, suav nrog) uas tuaj yeem yug thaum muaj khoov.
Ntug Tshuaj:
Zom txiav cov npoo tiv thaiv kom tiv thaiv kev ntxhov siab ntau.
2. Cov txheej txheem khoov
Tsawg kawg nkaus khoov vojvoog:
Siv lub vojvoog ntau dua lossis sib npaug2 × Khoom siv tuab(piv txwv li, 20mm rau 10mm Phaj) kom tsis txhob tawg.
Qeeb, tswjfwm kev deformation:
Zam rau kev ua phem; Cov xovxwm xovxwm hydraulic lossis kev teb khoov yog nyiam rauj.
Lubrication:
Siv cov roj nplaum roj (piv txwv li, molybdenum disculide) kom txo kev sib txhuam thiab kev puas tsuaj sab saum toj.
3. Tom qab kev ua haujlwm
Kev ntxhov siab nyem:
For severe bends (>15 Qib), Kev ntxhov siab tsawg-ntxhov siab nyem (250-300 degree) tej zaum yuav tsum tau los txo cov kev ntxhov siab uas seem.
Lub caij nplooj zeeg PATINATORATION:
Cov chaw ua haujlwm huv si nrog cov hlau txhuam thiab ua rau huab cua (lossis siv tshuaj tua hluav taws xob (lossis siv tshuaj tsuag patina-nrawm nrawm) txhawm rau txhim kho cov oxide txheej.
4. Tseem Ceeb tsis tau
Zam kev tshaj tawm: Tshaj tus hlau lub ductility txwv (≈18% elongation rau q500nh) txaus ntshai pob txha lov.
Tsis muaj cua sov: Localized heat (>150 Qib) tuaj yeem hloov microstructure, txo lub zog.
