Thaum cov lus qhia no tau ua raws,hnav phaj fabricationtuaj yeem ua tiav kev ua haujlwm txhim khu kev qha thiab tswj tau zoo heev rau kev puas tsuaj.
Nkag siab txog Fabrication Challenges ntawm AR Steel
Abrasion resistant steels xws li AR400, AR450, thiab AR500 yog tsim los ntawm quenching thiab tempering txheej txheem uas tsim ib tug hardened martensitic microstructure. Cov qauv no muab siab hardness thiab zoo heev hnav tsis kam.
Txawm li cas los xij, tib lub hardness uas txhim kho kev hnav kuj yuav tsum tau saib xyuas ntxiv thaum lub sij hawm fabrication. Kev siv hluav taws xob tsis raug lossis ntau dhau deformation tuaj yeem ua rau muaj teeb meem xws li:
- Thaum tshav kub kub- cuam tshuam thaj chaw softening
- Cracking thaum khoov
- Hydrogen{0}}induced weld cracking
- Poob hardness nyob ze qhov chaw weld
Hmoov zoo, cov teeb meem no tuaj yeem zam dhau los ntawm kev coj ua kom raug thiab cov txheej txheem tuav cov khoom.
Abrasion Resistant Hlau Txiav Txoj Kev
Txiav yog thawj kauj ruam hauv feem ntauhnav phaj fabricationtxheej txheem. Ob peb lub thev naus laus zis tuaj yeem siv rau kev puas ntsoog resistant steel nyob ntawm phaj thickness, xav tau precision, thiab ntau lawm efficiency.
Nplaim Txiav
Nplaim txiav yog ib txoj hauv kev siv ntau tshaj plaws rau cov phaj tuab. Thaumabrasion resistant steel txiavsiv oxy- roj teeb hluav taws xob, cov cua sov hauv zos tso cai rau cov hlau txiav kom zoo.
Txawm li cas los xij, cov khoom siv hluav taws xob yuav tsum tau ua tib zoo tswj kom tsis txhob muaj cua sov ntau dhau - thaj chaw cuam tshuam. Overheating tuaj yeem txo qhov tawv tawv nyob ze ntawm ntug txiav thiab cuam tshuam rau kev ua haujlwm ntawm cov khoom siv.
Preheating yog qee zaum pom zoo rau cov phaj tuab kom txo cov kev ntxhov siab thermal thiab txo qhov kev pheej hmoo ntawm kev tawg.
Plasma Txiav
Plasma txiav muab kev txiav nrawm dua thiab txhim kho qhov tseeb piv nrog cov nplaim taws. Nws yog dav siv rau nruab nrab -thickness hnav daim hlau hauv kev tsim khoom.
Qhov zoo ntawm plasma txiav muaj xws li:

Laser Txiav
Laser txiav muab lub siab tshaj plaws ntawm precision ntawm niaj hnub txiav technologies. Nws yog tshwj xeeb tshaj yog haum rau nyias nyias daim hlau thiab cov khoom uas yuav tsum tau nruj tolerances.
Vim tias laser txiav ua kom muaj cua sov nqaim- thaj tsam cuam tshuam, nws pab khaws cov hardness thiab cov yam ntxwv ntawm cov phaj hlau.
Txawm li cas los xij, laser txiav feem ntau txwv rau nyias phaj thicknesses piv nrog cov nplaim taws lossis ntshav txiav.
Khoov AR Phaj
Lwm yam txheej txheem hauvhnav phaj fabricationyog tsim los yog khoov lub phaj rau hauv cov geometry yuav tsum tau.
Vim tias abrasion resistant steel muaj siab hardness dua me ntsis steel,khoov AR phajyuav tsum tau loj dabtsi yog khoov radii thiab ntau dua forming rog.
Txias Khoov
Feem ntau AR steel daim hlau tuaj yeem ua kom txias khoov siv cov khoom siv xovxwm nres. Txawm li cas los xij, qhov tsawg tshaj plaws khoov vojvoog yuav tsum tau nce ntxiv thaum hardness nce.
Piv txwv li:
- AR400 feem ntau tso cai nruj dua dabtsi yog khoov radii
- AR450 yuav tsum tau loj bending radii
- AR500 xav tau qhov loj tshaj plaws khoov radii
Ua raws li cov lus qhia khoov tau pom zoo pab tiv thaiv kev tawg raws txoj kab khoov.
Bending Direction
Cov kev taw qhia ntawm dabtsi yog khoov tus txheeb ze rau dov kev taw qhia ntawm steel phaj kuj tseem cuam tshuam txoj kev ua tau zoo. Nyob rau hauv ntau zaus, khoov perpendicular mus rau dov kev taw qhia muab tau zoo dua thiab txo qhov kev pheej hmoo ntawm tawg.
Kev npaj kom zoo thaum lub sij hawm fabrication ua kom ntseeg tau qhov kev ua tau zoo rau kev puas tsuaj resistant steel Cheebtsam.
AR Hlau Vuam
Vuam yog ib kauj ruam tseem ceeb hauv kev sib sau cov khoom siv ua los ntawm cov hlau tsis muaj zog. Vim tias AR steels muaj zog dua thiab cov ntsiab lus alloy, cov txheej txheem vuam yuav tsum tau ua tib zoo tswj.
Tsawg Hydrogen Vuam Consumables
Thaum uaAR steel vuam, qis- hydrogen electrodes lossis vuam hlau raug pom zoo. Cov khoom siv no pab txo qis kev pheej hmoo ntawm hydrogen-induced cracking nyob rau hauv tshav kub- cuam tshuam cheeb tsam.
Preheating yuav tsum tau
Preheating feem ntau pom zoo thaum welding thicker hnav daim hlau. Preheating txo tus nqi cua txias thiab txo qis kev ntxhov siab hauv cheeb tsam weld.
Cov txiaj ntsig zoo ntawm preheating muaj xws li:
