Dab tsi yog qhov tshwm sim thiab ua rau delamination tsis xws luag nyob rau hauv txias -rolled coils?
A: Delamination tshwm sim raws li kev sib cais tsis tu ncua lossis tsis tu ncua ntawm tus ntoo khaub lig- ntu ntawm cov hlau sawb. Nws yooj yim rau kev delamination hauv cheeb tsam thaum lub sij hawm txiav thiab stamping, feem ntau nrog greyish -dawb lossis tsaus dub suav nrog ntawm cov khaubncaws sab nraud povtseg. Qhov laj thawj feem ntau yog qhov muaj ntau yam tsis yog-hlau sib xyaws hauv cov hlau matrix, uas sib cais nyob rau hauv kev ntxhov siab thaum txias dov.
Dab tsi yog qhov cuam tshuam ntawm qhov sib xyaw ntawm qhov txias -rolled coils?
A: Tsis yog-cov khoom siv hlau nyob hauv qab lossis rau saum npoo ntawm qhov txias- dov substrate, tom qab tawg thaum lub caij txias dov, raug rau ntawm cov hlau sawb nto, tshwm li cov dots tsis tu ncua lossis cov blocks. Qhov no ua rau kev puas tsuaj rau saum npoo, cuam tshuam rau txheej txheej thiab kev ua haujlwm stamping, thiab hauv cov xwm txheej hnyav, ua rau cov khoom seem.
Dab tsi ua rau qhov tsis sib xws ntawm qhov txias txias -rolled coils?
A: 1. Tsis tsim nyog dov thickness teem; 2. Raw khoom thickness fluctuations tshaj lub zeb tswj ntau yam; 3. Qhov ntsuas qhov ntsuas qhov ntsuas tsis raug lossis ua haujlwm tsis zoo ntawm AGC muaj nuj nqi; 4. Muaj qhov tsis xws luag hauv cov hlau sawb ntawm lub zeb inlet, yuav tsum tau tshwj xeeb dov txoj kev los hloov qhov kev tawm thickness.
Dab tsi yog qhov kev faib tawm ntawm cov qauv wavy hauv txias -rolled coils?
A: Raws li qhov dav thiab qhov chaw, cov qauv wavy tuaj yeem muab faib ua qhov nruab nrab wavy (nruab nrab ntawm lub strip), ntug wavy (ob sab ntawm lub strip), ib leeg -ntug wavy (ib sab), thiab tav wavy (nruab nrab ntawm ntug thiab nruab nrab). Cov duab wavy cuam tshuam rau kev ua haujlwm tom ntej thiab yuav tsum tau txhim kho los ntawm kev kho cov yob tsis.
Cov teeb meem dab tsi yuav impurities hauv emulsion ua rau txias -rolled coils?
A: Cov impurities nyob rau hauv emulsion, tom qab evaporation, nyob nruab nrab ntawm cov ntawv hlau thiab tuaj yeem ua rau hmoov; lawv kuj tuaj yeem ua rau muaj qhov tsis xws luag xws li pitting thiab chipping ntawm cov yob, yog li cuam tshuam rau qhov zoo ntawm qhov txias -rolled coil.
