Cov txheej txheem ntawm kev tsim EFW (Electric Fusion Welded) cov kav dej muaj cov kauj ruam zoo thiab rov ua dua. Cov txheej txheem no suav nrog cov hauv qab no:
1. Kev xaiv khoom: Thawj kauj ruam yog xaiv cov khoom siv raws li qhov xav tau ntawm tus neeg siv khoom. Cov khoom yuav yog stainless hlau, carbon hlau, los yog hlau alloy. Kev xaiv cov khoom siv zoo ua kom cov kav dej muaj zog dua thiab ua haujlwm ntev.
2. Txiav: Tom qab xaiv cov khoom siv, cov kav dej raug txiav rau hauv qhov ntev uas yuav tsum tau ua. Cov kav dej raug txiav siv cov tshuab CNC thiab cov kev ntsuas raug coj los xyuas kom meej tias tsis muaj cov khoom pov tseg.
3. Khoov: Cov kauj ruam tom ntej yog khoov cov kav dej kom lawv cov duab xav tau. Cov txheej txheem dabtsi yog khoov yog ua los ntawm cov txheej txheem automated uas ua kom muaj qhov tseeb thiab qhov tseeb.
4.Vuam: Tom qab cov kav dej tau khoov, lawv tau welded ua ke siv cov txheej txheem hluav taws xob fusion vuam. Cov txheej txheem no suav nrog cua sov qhov kawg ntawm cov kav dej thiab fusing lawv ua ke los tsim kom muaj zog thiab ruaj khov.
5.Kev sim: Ua ntej cov kav dej xa mus rau cov neeg siv khoom, lawv tau txais ntau yam kev ntsuam xyuas kom ntseeg tau tias lawv ua tau raws li cov qauv zoo. Kev ntsuam xyuas xws li kuaj hydrostatic, kuaj hluav taws xob, thiab kuaj ultrasonic yog ua los xyuas kom meej tias cov kav dej tsis xau thiab tsis muaj teeb meem.
6. Ua tiav: Cov kauj ruam kawg suav nrog kev ua tiav cov kav dej los ntawm polishing lossis txheej txheej los txhim kho lawv qhov kev zoo nkauj. Cov kav dej yog tom qab ntawd ntim thiab xa mus rau cov neeg siv khoom.
Zuag qhia tag nrho, cov txheej txheem tsim khoom ntawm EFW kav dej muaj zog thiab ua kom cov kav dej ua tau raws li cov qauv tsim nyog. Kev siv cov tshuab automated thiab kev ntsuas meej kom ntseeg tau tias muaj cov khoom pov tseg tsawg tsawg thiab cov khoom siv tau zoo.
