ua cov kauj ruam
Kev ua ntej:
Ua ntej, ua kev npaj ntug ntawm S690QL1 steel daim hlau, xws li kev sib tsoo lossis beveling, kom tshem tawm oxides, roj stains, thiab impurities. Qhov no tsis txhob tawg thaum lub sij hawm tom ntej vuam thiab ua kom nruj sib koom ua ke, tso lub hauv paus rau kev ua haujlwm ruaj khov.
Txiav:
Txais cov nplaim taws lossis plasma txiav. Tswj kev txiav ceev thiab cov cua kub tawm los tiv thaiv cov cua sov hauv zos ntau dhau, uas tuaj yeem ua rau cov quenched -tempered microstructure thiab txo cov khoom toughness. Tsis txhob ntxhib npoo uas yuav tsum tau trimming ntxiv.
tsim:
Kev khoov txias yog ua tau rau cov duab yooj yim tab sis yuav tsum muaj kev sib sau ntau dua. Rau cov txheej txheem nyuaj, tswj qis - qhov kub thiab txias yog xaiv tau los txo cov springback thiab tsis txhob tawg. Tom qab- kev tshuaj ntsuam xyuas kom tsis txhob muaj qhov deformation.
Vuam:
Preheat rau 80-120℃thiab tswj qhov kub thiab txias kom nruj. Siv cov khoom siv qis- hydrogen welding los tiv thaiv hydrogen-induced cracking. Tsis txhob overheating; tom qab-weld kev kho cua sov tuaj yeem ua rau cov khoom tseem ceeb los txo cov kev ntxhov siab uas seem.
Ua tiav:
Ua machining nrog nyuaj tooling thiab txo txiav ceev vim muaj zog siab. Ntxuav lub ntsej muag thiab tshuaj xyuas qhov tsis xws luag, ua kom cov khoom siv hluav taws xob ntawm cov khoom kawg ua tau raws li daim ntawv thov.
