Annealing yog txheej txheem tseem ceeb hauv kev lag luam vuam, tshwj xeeb tshaj yog nyob rau hauv lub taub qab vuam tshuab. Kab lus no tham txog qhov tseem ceeb ntawm annealing, nws cov txiaj ntsig, thiab cov xwm txheej uas nws tsim nyog los ua qhov kev kho cua sov no. Nkag siab thaum twg los thov annealing ua kom cov khoom zoo welded pob qij txha nrog txhim kho cov khoom siv.
Taw qhia: Annealing yog ib txoj kev kho cua sov uas muaj cua sov rau cov hlau mus rau qhov kub thiab txias thiab maj mam txias kom hloov nws cov microstructure. Nyob rau hauv lub taub qab vuam tshuab, annealing plays lub luag haujlwm tseem ceeb hauv kev txo qis kev ntxhov siab, txhim kho ductility, thiab txhim kho tag nrho cov vuam zoo.
- Cov ntaub ntawv tuab thiab muaj zog: Rau cov phaj hlau tuab lossis cov ntaub ntawv muaj zog, qhov ceev ceev thaum vuam tuaj yeem ua rau tawv tawv thiab brittleness, ua rau muaj peev xwm tawg. Nyob rau hauv xws li mob, annealing yog tsim nyog los kho cov khoom ductility thiab toughness.
- Kev Nyuaj Siab: Vuam tsim cov kev ntxhov siab nyob hauv qhov chaw sib koom ua ke, uas yuav ua rau muaj kev cuam tshuam los yog kev sib hloov ntawm cov khoom siv welded. Annealing pab daws cov kev ntxhov siab uas seem, txhawb kev ruaj ntseg thiab tiv thaiv kev cuam tshuam.
- Hardened Zones: Thaum lub sij hawm vuam, cov cua sov hauv cheeb tsam tuaj yeem tsim cov cheeb tsam tawv hauv cov hlau, ua rau muaj kev cuam tshuam tsis zoo rau cov vuam kev ncaj ncees. Annealing softens cov hardened cheeb tsam, tsim kom muaj ib tug ntau yam microstructure thoob plaws hauv lub sib koom tes.
- Kev kho cua sov tom qab vuam (PWHT): Hauv qee qhov kev siv, cov lej tshwj xeeb thiab cov qauv yuav xav tau kev kho cua sov tom qab vuam (PWHT) kom ntseeg tau tias vuam qhov kev ncaj ncees thiab ua tau raws li cov khoom siv tshwj xeeb. Annealing feem ntau yog ib feem ntawm cov txheej txheem PWHT.
- Npaj rau Vuam Ntxiv: Hauv ntau qhov kev siv vuam, tshwj xeeb tshaj yog thaum siv cov txheej txheem vuam sib txawv lossis cov ntaub ntawv muab tub lim, kev sib txhuam ntawm cov hlaws tuaj yeem pab tiv thaiv kev sib tsoo thiab ua kom pom kev sib xyaw ntawm cov txheej.
Nyob rau hauv lub taub qab vuam tshuab, annealing yog ib qho cuab yeej tseem ceeb los txhim kho qhov zoo ntawm cov pob qij txha thiab txo qhov kev pheej hmoo ntawm qhov tsis xws luag thiab tsis ua haujlwm. Paub thaum twg los thov annealing yog qhov tseem ceeb rau kev ua tiav cov khoom siv kho tshuab uas xav tau, txo cov kev ntxhov siab seem, thiab ua kom lub neej ntev ntawm cov khoom siv welded. Los ntawm kev sib koom ua ke rau hauv cov txheej txheem vuam thaum tsim nyog, cov welds tuaj yeem tsim cov vuam zoo thiab txhim khu kev qha, ua tau raws li cov qauv kev lag luam nruj tshaj plaws thiab cov neeg siv khoom xav tau.
