1.Dab tsi yog qhov tseem ceeb ntawm cov txheej txheem Kaiping?
Kev ua haujlwm ntawm txoj kab theem (lub tshuab ncaj) yog los kho cov duab ntawm cov ntawv hlau, tsis txhob tshem tawm cov kev ntxhov siab hauv cov khoom. Nws txoj hauv kev ua haujlwm suav nrog ntau zaus khoov thiab deforming cov ntawv hlau los ntawm cov staggered rollers kom ua tiav qhov muag pom thiab ntsuas qhov flatness.
Cov txheej txheem no tau rov faib cov kev ntxhov siab sab hauv: nws hloov pauv qhov kev ntxhov siab tsis sib xws uas ua rau cov ntawv tsis xws luag (xws li waviness, camber, thiab warping) rau hauv ib qho tshiab, ntau yam kev ntxhov siab sib npaug. Txawm li cas los xij, qhov sib npaug no yog "tus neeg kho tshuab" thiab "tsim," tsis yog nws tshem tawm kev ntxhov siab ntawm nws qhov chaw.
2.Dab tsi yog qhov yuav tsum tau ua rau siab - precision machining thiab seem stability?
Precision stamping / kos duab: Yog tias cov ntawv hlau qib siab xav tau cov txheej txheem sib sib zog nqus xws li kos duab sib sib zog nqus lossis kos duab zoo, qhov kev ntxhov siab yuav raug tso tawm thaum lub sijhawm tsim, ua rau muaj qhov tsis zoo, cov duab tsis sib haum, cov kab hauv qab (Lüders band), lossis txiv kab ntxwv tev kev ntxhib los mos. Kev ntxhov siab-Nyem annealing tuaj yeem txhim kho kev ruaj ntseg zoo.
High-precision machining: Thaum siv rau precision mechanical qhov chaw, rebalancing ntawm sab hauv kev nyuaj siab thaum lub sij hawm machining yuav ua rau qeeb deformation ntawm workpiece, compromising machining raug. Kev kho kev ntxhov siab yog qhov tseem ceeb ua ntej.
Raws li lub substrate rau pwm los yog gauges: siab heev ntev - lub sij hawm seem stability yuav tsum tau; kev ntxhov siab sab hauv yuav tsum raug tshem tawm tag nrho.
3.Dab tsi yog cov txheej txheem tom ntej uas muaj cov khoom siv hluav taws xob ntau?
Vuam: Qhov no yog qhov yuav tsum tau muaj thiab khaus. Cov cua sov hauv zos thaum lub sij hawm vuam ua rau muaj kev ntxhov siab loj heev, uas, ua ke nrog cov kev ntxhov siab uas twb muaj lawm hauv cov ntawv hlau, tuaj yeem ua rau muaj kev cuam tshuam loj heev thiab kev sib hloov ntawm cov welded qhov chaw. Kev ntxhov siab-relieving annealing ntawm cov ntawv hlau ua ntej vuam yog ib qho zoo tshaj plaws ntawm kev tswj vuam deformation.
Laser Txiav / Plasma Txiav: Txawm hais tias tshav kub- thaj tsam cuam tshuam me dua, qhov kev ntxhov siab tseem tuaj yeem cuam tshuam cov duab ntawm daim ntawv txiav, tshwj xeeb tshaj yog rau siab -precision, nyias- phaj, lossis nyuaj- zoo li txiav.
4.Dab tsi yog qhov tseem ceeb ntawm qhov txias -rolled coil?
Tag nrho hardened (unannealed) txias-rolled coils: Cov no muaj kev ua hauj lwm hnyav sab hauv thiab tsis tshua muaj siab residual siab. Txawm hais tias leveled, cov khoom siv yog ib qho nyuaj heev thiab muaj cov yas tsis zoo, ua rau nws tsis yooj yim sua kom ua txhua yam txheej txheem. Recrystallization annealing (tsis yog tsuas yog txhawm rau txo kev ntxhov siab xwb tab sis kuj tseem yuav rov qab kho cov yas) yog qhov tsim nyog ua ntej, thiab tom qab ntawd yuav tsum muaj kev ntsuas theem nrab nyob ntawm qhov xwm txheej.
Lub xeev Annealed (cov kab kev lag luam zoo ib yam): Cov no tau dhau los ua qhov kev sib tsoo thiab muaj kev ntxhov siab tsawg dua. Txawm hais tias lawv ua tau raws li qhov yuav tsum tau siv tom qab qib siab yog nyob ntawm cov ntsiab lus 1 thiab 2 saum toj no.
5.Puas muaj tej yam tshwj xeeb uas yuav tsum tau rau saum npoo zoo thiab txhua yam khoom?
Kev ntxhov siab- feem ntau ua rau kev ntxhov siab ntawm qhov kub thiab txias (hauv qab qhov kub ntawm recrystallization, xws li 550-650℃). Txawm hais tias me ntsis oxidation yuav tshwm sim, nws tswj cov khoom hardness tseem ceeb tsis hloov. Yog hais tias ua tiav oxidation tshem tawm thiab glossy nto yuav tsum tau, ci annealing yog tsim nyog.
