Ua ntej tshaj plaws, cia peb saib cov txheej txheem tsim khoom ntawm cov khoom siv tshuaj (annealing): Txawm hais tias cov txheej txheem vuam ntawm cov hlau tsis huv yog qhov paub tab, cov cua sov thiab txias ntawm cov txheej txheem vuam yog nyob rau hauv ib qho chaw me me thiab ua tiav hauv ib qho. instant ntawm qhov ceev ceev heev. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ua kom muaj zog thiab muaj zog cov khoom siv sab hauv kev ntxhov siab lossis kev kub nyhiab hauv zos ntawm qhov vuam. Yog li ntawd, lub hauv paus yuav tsum raug rau kev daws teeb meem (annealing) txheej txheem tom qab vuam. Tom qab xyoo ntawm kev tshawb fawb thiab kev tsim kho thiab kev hloov pauv, cov txheej txheem kev daws teeb meem tam sim no (annealing) yog twb muaj kev sib koom ua ke ntawm cov kab ntau lawm. On-line solid-melting (annealing) yog kom sov cov stainless hlau bellows nyob rau hauv ib tug solid-melting (annealing) khoom mus rau qhov kub ntawm 1100 degree nyob rau hauv ib tug inert tiv thaiv roj.. Tom qab ib lub sij hawm ntawm lub sij hawm nyob rau hauv qhov kub thiab txias ib puag ncig ntawm 1100 degree, nws yog maj mam txias ntawm lub ceev ceev, thiab tag nrho cov kab sib dhos yog ntau tshaj 40 meters. Lub hom phiaj tseem ceeb yog kom tshem tawm tag nrho cov kev ntxhov siab nyob rau hauv lub weld, thiaj li hais tias cov weld hardening thiab vuam softening thiab cov khoom unevenness ntawm weld tuaj yeem ua homogenized. Nyob rau tib lub sijhawm, kev ntxhov siab sab hauv tsim los ntawm cov txheej txheem txias dov ntawm cov hlau sawb thiab cov kev ntxhov siab sab hauv tsim los ntawm cov txheej txheem extrusion raug tshem tawm nyob rau hauv qhov kub ntawm qhov kub ntawm 1100 degree, kom cov hlau tsis muaj hlau molecules rov qab sib npaug. Yog li ntawd, cov yeeb nkab corrugated tsis yooj yim rau tawg, hloov tau yooj yim dua, yooj yim rau khoov thiab cov duab thaum lub sij hawm installation thiab siv, thiab muaj kev ruaj ntseg zoo dua. Nyob rau hauv cov txheej txheem no, qhov kub thiab txias kub, cua kub ceev thiab kub, thiab cua txias ceev (txias dej txias thiab txaus tus nqi) mas kho. Solid tov (annealing) plays lub luag haujlwm tseem ceeb hauv qhov zoo ntawm stainless hlau bellows!
Stainless hlau bellows tov (annealing)
Rau stainless hlau bellows kom muaj cov khoom zoo elastic, kev daws (annealing) yog ib qho tseem ceeb ntawm cov txheej txheem.
Cov tshuaj (annealing) ntawm lub hauv caug tuaj yeem tshem tawm kev ua haujlwm nyuaj thaum lub sijhawm tsim khoom, rov ua kom cov yas ntawm cov hlau tsis huv, thiab tib lub sijhawm ntxiv dag zog rau cov khoom thiab tau txais elasticity.
Kev daws teeb meem (annealing) kev kho ntawm bellows muaj nws cov kev xav tau zoo sab hauv thiab sab nraud.
Qhov kev xav tau sab hauv yog kom tau txais qee qhov microstructure, grain loj thiab txhua yam khoom ntawm cov khoom tom qab kev kho cua sov;
Qhov zoo sab nraud yog qhov tseem ceeb ntawm qhov chaw oxidation tom qab kho (annealing) kho.
Kev daws teeb meem (annealing) muaj lwm cov txiaj ntsig: nws yog kev kho deg du ntawm stainless hlau bellows
Cov txheej txheem kev kho deg smoothness ntawm stainless hlau bellows feem ntau suav nrog cov txheej txheem xws li degreasing, loosening oxide nplai thiab tu, kom cov khoom ntawm stainless hlau bellows yog du thiab huv si.
Yuav ua li cas kom paub qhov txawv ntawm cov stainless hlau bellows muaj cov khoom melting (annealing)?
1) Qhov saum npoo ntawm cov khoom-melting (annealed) bellows yog tshiab thiab huv si, thiab nws yog lub ntuj xim ntawm stainless hlau.
Yog tias tsis muaj cov khoom tawg, tnws nto yog dub thiab tsaus. Ua tib zoo saib ntawm qhov chaw tsis huv! Tsis muaj cov khoom melting (tsis muaj annealing) vim hais tias cov oxide txheej ntawm cov welded stainless hlau yeeb nkab yuav tsum tau kho, thiab nws yuav tsum tau electrolyzed, polished los yog pickled.
2) Tnws stainless hlau corrugated yeeb nkab yog welded rau hauv cov yeeb nkab steel los ntawm stainless hlau sawb, thiab ces corrugated los ua ib tug corrugated yeeb nkab. Nyob rau hauv tus txheej txheem ntawm welding stainless hlau yeeb nkab, ob lub teeb daj oxides yuav raug tso rau sab hauv thiab sab nraud ntawm vuam seam txheej. Yog tias koj ua tib zoo saib rau sab hauv ntawm lub hauv caug vuam seam, muaj cov xim xim daj lub teeb daj, cov kab no zoo li lub hauv siab uas tsis muaj fusion (tsis muaj annealing)!
3) Siv ib feem ntawm 30 cm ntev thiab luv corrugated yeeb nkab, khoov nws sai, thiab nws yuav tawg ntawm li 10 sij hawm. Qhov no corrugated yeeb nkab tsis tau solidified (annealed).
