Yuav ua li cas yog tias qhov hardness ntawm H13 cov khoom hloov pauv zoo heev tom qab tempering?
Tso lus
Kev tswj xyuas meej ntawm cov txheej txheem tempering, qhov cub qhov chaw thauj khoom, cov khoom siv raw ua ntej- kev tshuaj xyuas, thiab kev saib xyuas cov txheej txheem yog plaub yam ntawm kev ua kom zoo dua qub uas yuav tsum tau siv thaum lub hardness ntawm H13 cov khoom sib txawv heev tom qab tempering. Nrog rau ib qho kev hloov pauv tsawg dua los yog sib npaug rau 2 HRC, qhov no yuav lav tias qhov hardness ruaj khov ntawm 48 thiab 52 HRC.
1. Cov laj thawj thiab kev daws teeb meem
Ua rau thiab kho
Kub tsis sib haum
Txhawm rau kom paub tseeb tias qhov sib txawv ntawm qhov kub hauv lub cub tawg tsawg dua lossis sib npaug li ± 5 degree, siv PID qhov kub thiab txias -tswj lub qhov cub uas tau teem rau 580℃± 5℃thiab nyeem ntau qhov ntsuas kub.
Tsis ntseeg qhov txias txias
Txhawm rau ua kom qhov sib xws ntawm cov cua sov sib xws, khaws cov khoom ua haujlwm tsawg kawg 5 cm sib nrug, tsis txhob sib dhos, thiab siv cov cuab yeej racks.
Tsis txaus Tempering Cycles
Nws yuav siv ob lub voj voog ntawm tempering. Txias rau chav sov tom qab thawj tempering ua ntej nqa tawm thib ob.
Deviation nyob rau hauv Raw Material Composition
Ua ntej tempering, siv XRF los txiav txim seb puas yog Cr (5.0% ~ 5.5%), Mo (1.1% ~ 1.75%), thiab V (0.8% ~ 1.2%) ua tiav cov kev cai.
Cov ntaub ntawv tswv yim: Los ntawm kev txhim kho lub cub tawg load ceev thiab kub tswj qhov system, Jingmo Technology txo qhov hardness txawv ntawm H13 manifold daim hlau los ntawm 3.1 HRC rau 1.4 HRC.
2. Cov ntaub ntawv kaw voj thiab txheej txheem tswj
Daim -los ntawm-Piece Multi-Point Inspection: Txiav txim siab qhov ntau, ntsuas peb mus rau tsib qhov chaw ntawm txhua daim (nruab nrab, ntug, thickness ciam teb), thiab xyuas kom meej tias HRC tsawg dua ob;
Kev txheeb xyuas ntawm Metallographic Sampling: Ntau dua lossis sib npaug li 5% ntawm txhua pawg yog kuaj los xyuas kom meej tias cov microstructure muaj cov carbides tawg thiab homogenous tempered martensite;
Ua kom sov sov Curves: Txhawm rau tsim cov txheej txheem traceability, khaws cov ntaub ntawv ua kom sov thiab txias rau txhua qhov cub;
Tsim Cov Ntaub Ntawv Zoo: Txhawm rau ua kom cov teeb meem tshuaj xyuas yooj yim dua, khaws cov ntaub ntawv hardness, tus neeg teb xov tooj cov ntsiab lus, thiab cov khoom siv tooj.
Tswv yim: Yuav kom pom qhov sib txawv ntawm qhov sib txawv sai sai (xws li qhov poob qis hauv qhov nruab nrab hardness), cov kab kos tuaj yeem tsim tau siv cov ntaub ntawv los ntawm ntau cov khoom ua tiav.
3. Cov lus qhia rau On -Site Optimization
Muab cov chaw muab kev pabcuam kev ua raws cai hauv zos ua ntej, xws li Wuhan Heat Treatment Plant thiab Jingmo Technology, uas pab txhawb kev xa khoom sai thiab kev qhia dav;
Ua kom pom tseeb ntawm qhov siab - ntsuas kub: Kom tsis txhob thermal softening cuam tshuam cov kev nyeem ntawv, txias lub workpiece mus rau chav tsev kub (<50°C) before measuring;
Ua ntej siv lub cuab yeej, calibrate nws. Xyuas kom tseeb tias qhov tsis raug yog tsawg dua lossis sib npaug rau ± 1 HRC ntawm tus qauv thaiv kom tsis txhob muaj qhov sib txawv.
"Qhov kub thiab txias, muaj pes tsawg leeg ntawm kev sim, thiab cov ntaub ntawv khaws cia" yog cov qauv kev nyab xeeb uas ua kom tiav cov txheej txheem tswj thiab rov tsim dua tshiab.
