Dab tsi yog trimmed ntug thiab burrs ntawm galvanized coils? Dab tsi yog qhov txawv ntawm lawv cov tsos?
Teb: Trimmed npoo xa mus rau cov npoo ntawm cov hlau sawb raug txiav tawm siv lub voj voog thaum lub sij hawm tsim khoom lossis cov txheej txheem slitting ntawm galvanized coils, ua rau zoo huv si, burr - dawb npoo nrog meej thiab zoo ib yam dav. Burrs, ntawm qhov tod tes, yog cov npoo ntuj ntawm qhov qub kub - dov los yog txias - dov strip yam tsis muaj trimming. Cov npoo no yuav tsis sib xws, muaj me ntsis burrs, lossis me me tawg. Nyob rau hauv luv luv, trimmed npoo yog du thiab dimensionally meej, thaum burrs muaj ntxhib npoo thiab loj dav tolerances.
Hauv qhov xwm txheej twg yuav tsum yog ntug- trimmed galvanized coils yuav nyiam?
Teb: Thaum galvanized coils yog siv rau kev thov vuam, pleev xim, lossis cov txheej txheem sib sib zog nqus, cov ntug- trimmed coils yuav tsum nyiam dua. Ntug trimming tshem tawm burrs thiab micro- tawg, tiv thaiv porosity lossis spatter thaum vuam; cov npoo du ua kom yooj yim txawm tias txheej txheej thiab tiv thaiv ntug corrosion; nyob rau hauv daim ntawv thov uas yuav tsum tau seams meej, xws li automotive sab nrauv panels thiab cov khoom vaj tse, ntug trimming kom zoo sib xws qhov sib txawv, kev txhim kho cov tsos thiab zoo ntawm cov khoom tiav.
Dab tsi yog qhov zoo ntawm kev siv ntxhib -edged galvanized coils? Nyob rau hauv dab tsi scenarios yog ntxhib -edged coils haum?
Teb: Qhov txiaj ntsig loj tshaj plaws ntawm cov khoom ntxhib -edged galvanized coils yog lawv cov nqi qis, vim tias ntug- txheej txheem txiav raug tshem tawm, txo cov khoom pov tseg thiab lub sijhawm ua haujlwm. Lawv tsim nyog rau cov ntawv thov uas qhov kev xav tau ntawm ntug tsis siab, xws li kev tsim cov ntawv corrugated, qhov cua ducts, cable tais, thiab yooj yim txee; los yog qhov uas tom qab ua tiav yuav koom nrog longitudinal slitting los yog theem nrab txiav, thaum kawg tshem tawm cov npoo; thiab rau cov qauv kev txhawb nqa cov khoom uas tsis zoo nkauj, qhov twg me me ntawm burrs ntawm cov npoo tsis cuam tshuam rau kev ua haujlwm.
Yuav ua li cas xaiv ntawm trimmed npoo thiab burrs cuam tshuam rau ntug corrosion kuj ntawm galvanized txheej?
Teb: Trimmed npoo nthuav tawm cov hlau tshiab substrate tom qab shearing, thiab zinc txheej yog cuam tshuam ntawm qhov chaw txiav. Yog tsis muaj xeb tiv thaiv kev kho mob, ntu no yog tsim los tsim cov xeb liab ua ntej. Burrs, ntawm qhov tod tes, khaws cov txheej txheej qub, ua rau cov txheej txheem zinc txuas ntxiv thiab theoretically zoo dua ntug corrosion kuj. Txawm li cas los xij, hauv kev xyaum, burr npoo yuav muaj micro- tawg lossis thaj chaw uas tsis zoo zinc txheej adhesion, uas tuaj yeem ua cov ntsiab lus pib corrosion. Yog li ntawd, rau siab corrosion kuj, nws yog advisable mus thov ntug tiv thaiv ciab los yog ua passivation kev kho mob tom qab trimming, es tsis txhob cia siab rau ib leeg ntawm trimmed los yog burr npoo lawv tus kheej.
Yuav ua li cas technical thiab economic yam yuav tsum tau xav txog thaum xaiv ntawm trimmed ntug thiab burrs?
Teb: Cov kev txiav txim siab tseem ceeb yog tsib lub ntsiab lus hauv qab no: Ua ntej, qhov yuav tsum tau muaj qhov dav qhov tseeb ntawm cov khoom tiav. Trimmed npoo tuaj yeem ua tiav qhov kam rau ua nyob rau hauv ± 0.5mm, thaum burrs feem ntau muaj kev kam rau siab ntawm ± 3 ~ 5mm. Thib ob, cov txheej txheem ua tom ntej. Vuam thiab tsis siv neeg stamping yog nyiam rau cov npoo trimmed. Thib peb, kev siv cov khoom siv. Trimmed npoo poob kwv yees li 1% ~ 3% ntawm ntug hlau. Plaub, kev siv nyiaj txiag. Burrs tuaj yeem txuag tau kaum rau ntau pua yuan ib tuj hauv cov nqi ua haujlwm. Thib tsib, lub sijhawm khoom xa tuaj. Trimmed npoo yuav tsum tau ua tiav cov txheej txheem ntxiv, ua rau lub sijhawm xa khoom ntev dua. Trimmed edges feem ntau yog xaiv rau siab-zoo, precision Cheebtsam los yog export txiav txim, thaum burrs raug xaiv rau qis-kawg, siab- ntim, lossis sab hauv tsis yog{18}} daim ntawv thov tseem ceeb.
