1.Yuav ua li cas txiav txim siab ua ntej?
Online Automated Inspection (Kev Tiv Thaiv thiab Saib Xyuas)
Surface Quality Inspection System: Cov cuab yeej txheem ntawm cov kab txias txias niaj hnub no, siv lub tshuab tsis pom kev (kab scan lub koob yees duab + lub teeb tshwj xeeb). Lub kaw lus tuaj yeem txheeb xyuas qhov pits (tshwj xeeb raws li cov yam ntxwv tsaus nti) hauv lub sijhawm tiag tiag, ua rau lub tswb nrov, cim qhov chaw, thiab muab cov qhab nia hauv chav tswj. Nws yog ib qho tseem ceeb rau kev tswj batch defects.
Kev tshuaj xyuas phau ntawv: Siv lub stroboscope, lub siab -ceev txav sawb yog "khov" ntawm qhov chaw tawm kom yooj yim pom.
Offline Macroscopic Inspection (Thawj Kauj Ruam, Kev Ntsuam Xyuas Qhov Tseem Ceeb) Thaum tshawb pom cov teeb meem yob, yuav tsum muaj cov ncauj lus kom ntxaws soj ntsuam zoo li qub:
Teeb pom kev zoo thiab kev soj ntsuam: Siv lub teeb nyem muaj zog lossis LED lub teeb sawb ntawm lub kaum sab xis, qhov pits yuav pom vim qhov sib txawv ntawm lub teeb. Saib xyuas lawv qhov kev faib tawm:
Periodic/Regular Distribution: Kev tshwm sim ntawm qhov sib npaug ntawm cov kev taw qhia dov yog ib yam ntxwv ntawm kev puas tsuaj ntawm yob nto (xws li chipping lossis sticking). Ntsuas qhov kev ncua deb L ntawm cov qhov uas nyob ib sab. Yog tias L=π × yob txoj kab uas hla, cov yob muaj teeb meem tuaj yeem txheeb xyuas tau.
Random/clustered faib: Feem ntau tshwm sim los ntawm txawv teb chaws teeb meem indentation (xws li hlau oxide scale, cub tawg nodules, refractory ntaub ntawv) los yog genetic defects nyob rau hauv cov ntaub ntawv raw.
Ua kom pom tseeb ntawm cov npoo los yog qhov kawg: Tej zaum yuav cuam tshuam nrog kev sib tsoo los yog shear burrs.
Kev ntsuam xyuas tactile: Xav seb cov npoo ntawm cov hniav yog qhov ntse lossis sib npaug, thiab seb lub hauv qab puas tiaj tus.
Daim kab xev lamination txoj kev: Ib txoj kev sau pov thawj ceev. High-pob tshab daim kab xev los yog mos silicone yog nias rau ntawm qhov chaw; Tom qab tshem tawm, ib qho pwm tsis zoo tau txais.
2.Yuav ua li cas txhawm rau txheeb xyuas peb -dimensional morphology thiab qhov ntev?
Cov cuab yeej: Dawb lub teeb interferometer / 3D nto profileometer.
Muaj nuj nqi: Txhawm rau ntsuas qhov tob, qhov dav, ntim, thiab ntug kaum ntawm qhov pits. Qhov sib txawv ntawm cov ntse "cuam tshuam craters" thiab maj mam "indentation craters" yog qhov tseem ceeb rau kev txiav txim siab txog lawv qhov laj thawj.
3.Yuav ua li cas soj ntsuam microscopic morphology thiab muaj pes tsawg leeg?
Cov cuab yeej: Scanning electron microscope ua ke nrog lub zog dispersive spectroscopy (EDS).
Txheej Txheem Kev Tshawb Fawb thiab Diagnostic Logic:
Kev soj ntsuam Microscopic Morphology: Saib xyuas hauv qab thiab cov npoo ntawm lub qhov dej ntawm qhov kev nthuav dav siab kom kuaj xyuas cov khoom seem txawv teb chaws, cov khoom tawg, cov cim yaj, thiab lwm yam.
EDS Composition Analysis: Qhov no yog kauj ruam tseem ceeb tshaj plaws. Ua micro- thaj tsam kev txheeb xyuas thaj chaw nyob rau hauv qab ntawm lub pits kom ncaj qha txheeb xyuas qhov chaw paug raws li qhov muaj pes tsawg leeg:
Kev kuaj xyuas feem ntau yog Fe thiab O → Hlau oxide nplai indentation. Qhia tias tsis tiav kub dov descaling los yog tsis txaus pickling.
Kev kuaj pom ntawm Al, Si, Ca, Mg, thiab lwm yam → Cov khoom siv hluav taws xob / slag indentation. Qhia txog steelmaking, nruam casting, los yog cua sov txheej txheem.
Kev kuaj pom ntawm Cu, Zn, Sn, thiab lwm yam. → Copper/non-ferrous hlau paug. Qhia txog kev hnav lossis txawv teb chaws muaj kab mob hauv cov lus qhia, bearings, thiab lwm yam.
Kev kuaj pom qhov txawv txav siab C cov ntsiab lus → Rolling roj coking hais los yog cov organic teeb meem indentation.
Kev sib xyaw ua ke zoo ib yam rau cov matrix → Tejzaum nws tshwm sim los ntawm cov khoom siv raw npuas lossis yob puas.
4.Yuav ua li cas txheeb xyuas tus ntoo khaub lig metallographic-section?
Txoj Kev: Cov qauv raug txiav tawm mus rau qhov chaw los npaj cov qauv metallographic.
Kev soj ntsuam: Cov kab hlau ntws hauv qab lub qhov dej tau kuaj xyuas qhov deformation, microcracks, cov qauv matrix txawv txav, thiab suav nrog hauv qab. Qhov no txheeb xyuas cov txiaj ntsig ntawm lub zog dispersive spectroscopy (EDS) thiab ntsuas qhov cuam tshuam ntawm qhov tsis xws ntawm cov khoom siv.
5.Dab tsi yog qee qhov kev coj ua?
Kauj Ruam 1 (Kev Teb nrawm): Thaum nrhiav tau ib lub qhov, tam sim ntawd sau nws qhov chaw thiab siv lub teeb nyem ntawm lub kaum sab xis txhawm rau txiav txim siab nws qhov kev faib tawm. Yog hais tias nws yog ncua sij hawm, tam sim ntawd nres txoj kab thiab tshuaj xyuas cov sib thooj yob.
Kauj Ruam 2 (Sampling thiab Analysis): Rau qhov random pits, coj mus kuaj thiab xa mus rau chav kuaj. Qhov kev ntsuam xyuas zoo dua thiab ua tau zoo tshaj plaws yog SEM / EDS kev tshuaj ntsuam xyuas, uas tuaj yeem muab qhov qhia meej meej sai.
Kauj Ruam 3 (Lub hauv paus Rectification): Raws li cov txheej txheem qhia hauv daim ntawv tshaj tawm (xws li, kub dov, pickling, steelmaking), tshawb xyuas cov txheej txheem tshwj xeeb lossis cov khoom siv ntsig txog cov txheej txheem (piv txwv li, descaling siab, acid concentration, furnace yob mob, qhia kev huv, thiab lwm yam).
Kauj Ruam 4 (Kev Tiv Thaiv Kev Tiv Thaiv): Txhim kho kev tshuaj xyuas cov khoom tuaj; tsis tu ncua tshuaj xyuas thiab zom cov yob; tswj cov kab ntau lawm huv si; optimize cov txheej txheem tseem ceeb.
