Cov iav cov khoom tau siv nyob rau txhua qhov ntawm peb lub neej, tab sis koj puas paub? Dab tsi yog qhov tseem ceeb tshaj plaws ntawm cov khoom iav tom qab kev tsim khoom thiab kev ua? Yog lawm, nws yog annealing. Niaj hnub no, cia peb txuas ntxiv nthuav dav ntawm anealing txheej txheem ntawm iav hauv qhov cub cua sov.
Annealing txheej txheem ntawm iav ncaj qha cuam tshuam qhov zoo thiab kev ua tau ntawm iav. Tom qab cov khoom iav raug yuam kom rhuab, deformed, txiav lossis rub tawm thaum lub sijhawm ua, kev ntxhov siab sab hauv yuav tsim tawm ntawm lub khob. Kev ntxhov siab sab hauv yuav ua rau lub khob kom tawg lossis tawg. Cov nyiaj pab menyuam tau sib tham txog niaj hnub no yog cov protagonist los daws cov teeb meem sab hauv kom ua tiav lub zog ntawm cov khoom siv ntawm cov iav (peb tuaj yeem siv covAnnealing Rauvkom tiav nws). Ib qho ntxiv, kev anealing txheej txheem tseem tuaj yeem ua tau zoo tshem tawm impurities thiab npuas nyob rau saum npoo ntawm lub khob, li kev txhim kho cov pob tshab thiab tsos ntawm lub khob.
Cov txheej txheem ntawm iav annealing suav nrog tsib theem: theem ua ntej, cov cua sov, qeeb theem thiab txias theem.
Ua ntej tshaj plaws, theem ua preheating yog thawj kauj ruam ntawm iav annealing. Nyob rau lub sijhawm no, cov iav tuaj yeem yog me ntsis rhuab, tab sis qhov kub yuav tsum tsis txhob siab dhau, feem ntau tswj tau ntawm li 300 degree. Qhov no yog vim tias cua sov kub heev nyob rau theem tom qab. Txhawm rau kom tsis txhob muaj lub khob los ntawm kev kub ntxhov los ntawm kev kub siab thiab tsim cov theem tshiab yog tsim kom maj mam hloov kho rau cov txheej txheem los ntawm qhov kub tsawg rau qhov kub thiab txias. Qhov no yog ib kauj ruam tsim nyog.
Tom qab ntawd, hauv cov cua sov, cov iav cov khoom yog muab rhaub kom sov rau qhov kub thiab txias kom tshem tawm sab hauv kev ntxhov siab. Lub annealing kub yog feem ntau 20 degree mus rau 3000 teev thiab 600 lub sijhawm yog, lub sijhawm ntsuas kub yog, qhov ntev ntawm lub sijhawm ntawm cov iav cov khoom lag luam) kom muab cov iav ntxhov siab kiag li.
Thaum kev ntxhov siab nyob rau saum npoo ntawm lub khob yuav luag tso tawm, qhov kub maj mam txo qis. Zoo ib yam li preheating, qeeb qeeb qeeb siv tau los tso cai rau lub khob maj mam yoog thiab zam kev tawg vim qhov tawg ntau dhau. Feem ntau, nws raug hloov kho kom qeeb ntawm 20 degree thiab 30 degree qis dua li anealing kub.
Thaum kawg, cov theem txias nkag mus. Tom qab qeeb txias, qhov cua txias txias tuaj yeem nrawm nrawm rau lub sijhawm thiab txuag cov khoom siv. Pab ntsuas qhov kub ntawm cov iav cov khoom kom poob mus rau chav tsev kub, kom cov iav ua tau zoo, zoo nkauj, ruaj thiab muaj zog.
Yog lawm, thaum lub sijhawm Annealing txheej txheem, peb kuj yuav tsum tau them cov teeb meem kev nyab xeeb xws li ua iav, thiab nruj me ntsis ua raws li kev siv cov iav annealing rauv; Hnav cov khoom tiv thaiv tiv thaiv kom tsis txhob khob tawg, kub kub hlawv thiab lwm yam teeb meem; Thaum kawg, kuaj xyuas cov khoom siv hauv Circuit Court thiab tshuab cov khoom siv kom tsis txhob muaj kev huam yuaj.
Yuav ua li cas txog nws, los ntawm cov lus qhia yooj yim no, koj puas muaj kev nkag siab ntawm cov txheej txheem ntawm iav annealing hauv lub rhaub dej? Yog koj xav tauAnnealing Furnaces, txais tos tuaj xyuas peb lub vev xaib thiab sab laj!
