Cov yam ntxwv thiab kev tswj xyuas ntawm tooj liab zoo hom annealing rauv

Zoo hom annealing furnaces yog dav siv, feem ntau yog rau annealing tshav kub kev kho mob ntawm ntau yam hlau cov ntaub ntawv. Tom qab annealing, lub workpiece tuaj yeem ua kom huv si yam tsis muaj oxidation lossis decarburization, thiab tuaj yeem siv rau lub tshuab nqus tsev nrog lub tshuab nqus tsev twj tso kua mis kom cov khoom ua haujlwm ci. Ua ntau lub qhov cub, tso tsheb hlau luam, thiab cov txheej txheem ib txhij tuaj yeem txhim kho kev ua haujlwm, txo kev siv, thiab txo cov nqi tsim khoom.
Lub siab huv thiab ci ntsa iab zoo hom annealing rauv yog tsim tshwj xeeb rau annealing tooj liab coil tubes thiab hauv cov threaded raj. Lub raj annealing tau txais cov txheej txheem tshwj xeeb sab hauv tshuab, thiab cov roj tiv thaiv yog siv rau hauv qhov cub kom muaj kev huv huv thiab ci ntsa iab ntawm sab hauv thiab sab nrauv ntawm cov raj. Nws cov yam ntxwv muaj xws li:
① Zoo airtightness, siv roj resistant roj hmab sealing daim ntawv.
② Annealing nyob rau hauv ib qho chaw tiv thaiv, ua kom lub ntsej muag ci, siv lub tshuab nqus tsev twj tso kua mis kom tshem tawm cov cua los ntawm lub cub tawg, thiab tom qab ntawd sau nws nrog nitrogen kom ua tiav cov roj tiv thaiv.
③ Cov txheej txheem tu thiab kho tshwj xeeb, siv cov roj purity nitrogen kom tshuab tuaj yeem tshem tawm cov roj lubricating seem nyob rau txhua lub sijhawm thiab ntxiv cov roj nitrogen tshiab.
④ Kev txuag hluav taws xob thiab txuag hluav taws xob, lub tshuab hluav taws xob tau nruab nrog lub kiv cua muaj zog convection, uas ua rau cov cua sov hloov pauv hauv lub cub tawg thiab txo lub sijhawm cua sov thiab txias.
⑤ ntse tswj qhov system.
Raws li cov yam ntxwv saum toj no, nrog rau cov txheej txheem ntawm qhov chaw ntawm lub Hoobkas thiab kev tshawb nrhiav thiab kev tsom xam ntawm qhov ntsuas kub ntawm lub tshuab hluav taws xob annealing nyob rau theem pib. Tag nrho cov tshuab hluav taws xob tswj hluav taws xob yuav tsum tau ua kom tau raws li cov kev qhia ua haujlwm hauv qab no:
(1) Kev tswj qhov kub thiab txias ntawm lub qhov cub hluav taws xob yuav tsum muaj kev ruaj ntseg zoo, thiab cov txheej txheem annealing yog kwv yees li theem kawg ntawm tag nrho cov tooj liab coil ntau lawm, yog li nws yog ib qho tsim nyog los xyuas kom meej cov txheej txheem ntau lawm.
(2) Lub kaw lus yuav tsum muaj kev ruaj ntseg siab. Vim muaj ntau yam tsis sib xws ntawm tag nrho cov kev tswj hwm, nws yuav tsum tau ua kom tiav hauv cov txheej txheem tsim, nrog rau kev nyab xeeb yog qhov tseem ceeb tshaj plaws. Tsis tas li ntawd, nws kuj yuav tsum muaj kev tswj xyuas zoo.
(3) Lub kaw lus yuav tsum muaj qee qhov kev hloov pauv thiab muaj peev xwm tiv thaiv kev cuam tshuam. Vim muaj ntau qhov sib txawv thiab kev cuam tshuam tsis zoo hauv cov chaw lag luam qhuav, lub kaw lus yuav tsum muaj peev xwm hloov pauv tau los daws lawv. Piv txwv li, qhov cuam tshuam ntawm kev thauj khoom ntawm cov cua sov thiab kev laus ntawm cov khoom siv lub sijhawm.
(4) Vim lub hysteresis ntawm qhov kub thiab txias nyob rau hauv lub zoo hom annealing rauv, cov zis feem ntau tsis tuaj yeem ua raws li sai sai thaum lub tswv yim hloov. Yog li ntawd, txhawm rau kom ua tiav qhov ntsuas kub kom raug, lub kaw lus yuav tsum muaj kev ua haujlwm zoo dynamic taug qab.
