1.Yuav ua li cas cov kev ntsuam xyuas ceev tau ua tiav?
Dimensions thiab tsos: Thickness, dav, unevenness, nto tiav, thiab tsis muaj khawb. Yuav ua kom tiav tam sim ntawd lossis tsis pub dhau ob teev.
Cov cuab yeej siv tshuab yooj yim: Kev ntsuas tensile (ntsuas lub zog tensile, tawm lub zog, thiab elongation), kev sim hardness. Cov txiaj ntsig feem ntau muaj nyob rau hauv ib hnub ua haujlwm tom qab kev npaj ua qauv.
2.Yuav ua li cas complex lossis tshwj xeeb tej yaam num cuam tshuam rau lub voj voog kuaj?
Tshuaj muaj pes tsawg leeg tsom xam: Spectroscopic tsom xam yog ceev, tab sis leej carbon- tsom xam sulfur los yog lub ntsiab tsom xam yuav siv sij hawm.
Metallographic tsom xam: suav nrog grain loj, suav nrog kev ntsuas, thiab kev soj ntsuam microstructural. Kev npaj yuav tsum tau ua (txiav, mounting, sib tsoo, polishing, etching), feem ntau siv 1-3 hnub ua haujlwm.
Kev xeem Formability: xws li kev xeem cupping, bending test, thiab lwm yam.
Kev ntsuam xyuas kev ua tau zoo ntawm txheej: Rau txias- dov coils nrog txheej (zinc plating, tin plating), kuaj txheej thickness, adhesion, corrosion kuj (tsim tshuaj tsuag), thiab lwm yam. ntsev tsuag tshuaj ntsuam lawv tus kheej yuav tsum tau ntev li ntawm 24 teev mus rau ob peb puas teev, lub sij hawm ntev heev.
Kev kuaj kev qaug zog, kev sim cuam tshuam, thiab lwm yam.: Cov kev sim tshwj xeeb no tseem siv sijhawm ntau dua -siv.
3.Dab tsi yog qhov chaw thiab cov txheej txheem rau kev xeem?
Kev tshuaj xyuas cov hlau zeb tawm: Cov hlau loj loj muaj lawv qhov chaw sim. Raws li ib feem ntawm cov txheej txheem tswj kom zoo, cov ntaub ntawv xeem nrog cov khoom. Qhov kev sim no yog synchronized nrog lub voj voog ntau lawm hauv lub sijhawm.
Cov neeg siv khoom tuaj xyuas:
Sampling: Thaum tau txais cov khoom, sampling yuav tsum tau teem caij.
Kev npaj ua piv txwv: Cov qauv ua tiav rau hauv cov qauv xeem.
Kev xeem thiab kev txheeb xyuas: Lub chaw kuaj sim ua qhov kev sim thiab teeb tsa ib daim ntawv qhia sab hauv.
Tag nrho cov txheej txheem, thaum txhim kho smoothly, feem ntau siv 1-2 hnub.
4.Dab tsi yog cov txheej txheem rau kev xeem tawm mus rau lwm tus neeg sab nrauv?
Kev xa khoom xa tuaj / ntawm -Sampling ntawm qhov chaw: suav nrog lub sijhawm thauj khoom.
Daim ntawv cog lus thiab kev them nyiaj: Cov txheej txheem ua lag luam.
Queues: Cov chaw sim loj muaj ntau qhov xwm txheej thiab yuav tsum tau queuing.
Kev xeem thiab kev npaj qhia: Ua tiav ntawm kev xeem thiab muab cov ntaub ntawv tshaj tawm ua lus Suav thiab Askiv.
Yog li ntawd, ib lub lim tiam (5-7 hnub ua hauj lwm) yog lub hauv paus txheej txheem; Cov teeb meem nyuaj yuav xav tau 10 hnub lossis ntev dua.
5.Dab tsi yog cov qauv ntsuas cov khoom siv rau txias-rolled coils?
Ceev tshaj plaws: Tsuas yog kev kuaj pom thiab qhov loj me, npaj tam sim ntawd.
Standard: Basic nyob rau hauv -Kev ntsuas kev ua tau zoo hauv tsev, 1-2 hnub.
Ua kom tiav Standard: thib peb- tog puv- khoom kuaj, 5-10 hnub ua haujlwm.
Ntev tshaj plaws: suav nrog qhov ntev - kuaj lub sijhawm ntev (xws li tshuaj tsuag ntsev), ob peb lub lis piam lossis ntau lub hlis.
