Cov txheej txheem tseem ceeb rau kev ruaj khov ntawm cov khoom siv H13 yog kev tswj xyuas meej ntawm cov txheej txheem tempering, cov txheej txheem ntawm lub tshuab ua kom sov, kev siv ob txheej txheem tempering, thiab ntxiv dag zog ua ntej - tshuaj xyuas cov khoom siv raw thiab cov txheej txheem saib xyuas kom ntseeg tau tias qhov hardness tsis tu ncua nyob rau hauv thaj tsam ntawm 48 ~ 52 HRC thiab qhov sib npaug ntawm cov khoom sib npaug li 2 HRC.
1. Kev Tswj Xyuas Qhov Tseem Ceeb
Ntsuas piav qhia
Precise Tempering Temperature Control: nruj me ntsis tswj qhov kub ntawm 550 ~ 600 degree, nrog 580℃± 5℃pom zoo. Txhua ± 10℃kev hloov pauv tuaj yeem ua rau muaj kev hloov pauv ntawm 1 ~ 2 HRC.
Muab ob npaug rau Tempering: Txias rau hauv chav sov tom qab thawj tempering ua ntej ua qhov thib ob tempering los tiv thaiv qhov seem ntawm kev ntxhov siab.
Standardized Furnace Loading Method: Khaws qhov sib nrug ntawm ntau dua lossis sib npaug li 5cm ntawm cov khoom ua haujlwm kom tsis txhob muaj kev sib tsoo thiab ua kom cov cua kub zoo sib xws.
Raw Material Composition Pre- tshuaj xyuas: Siv XRF los kuaj seb Cr (5.0% ~ 5.5%), Mo (1.1% ~ 1.75%), thiab V (0.8% ~ 1.2%) ua tau raws li cov qauv.
PID Temperature Controlled Furnace + Multi-point Temperature Measurement: Tswj qhov kub thiab txias nyob rau hauv lub cub tawg nyob rau hauv ± 5 degree, thiab tuav ib tug ua tiav furnace kub nkhaus rau txhua lub cub tawg.
Cov ntaub ntawv siv tau: Jingmo Technology txo qhov hardness ntau ntawm H13 manifold daim hlau los ntawm 3.1 HRC rau 1.4 HRC los ntawm kev ua kom lub qhov cub ua kom zoo dua qub thiab tswj qhov kub thiab txias.
2. Txheej txheem saib xyuas thiab cov ntaub ntawv kaw voj
Daim -los ntawm-Piece Multi-Point Inspection: Siv lub portable hardness tester, ntsuas 3-5 ntsiab lus rau ib thooj (center, ntug, thickness ciam teb), thiab xam qhov ntau.
Metallographic Sampling Verification: Sampling Ntau dua lossis sib npaug li 5% ntawm txhua pawg kom paub meej tias lub microstructure yog ib yam tempered martensite + dispersed carbides.
Tsim Cov Ntaub Ntawv Zoo: Cov ntaub ntawv sau rau hauv qhov cub kub qhov nkhaus, cov ntaub ntawv hardness, thiab cov ntaub ntawv tus neeg teb xov tooj rau txhua pawg kom ua tiav kev tswj xyuas.
Kev Tshawb Fawb Txog Kev Tshawb Fawb thiab Kev Ceeb Toom Thaum Ntxov: Plotting tswj cov kab kos rau ntau qhov sib law liag txhawm rau txheeb xyuas qhov kev hloov pauv hauv lub cev lossis nce hauv kev tawg.
Piv txwv li: Ib lub tuam txhab nrhiav pom tias qhov nruab nrab hardness ntawm peb cov khoom sib law liag tau txo los ntawm 49.6 → 48.1 → 47.3 HRC, uas tau tshawb xyuas los ntawm qhov kub thiab txias ntawm lub cub tawg.
3. Ntawm -Qhov Kev Pom Zoo Tshaj Plaws
Ua ntej cov chaw muab kev pabcuam raws li hauv zos: xws li Wuhan Heat Treatment Plant thiab Jingmo Technology, uas txhawb nqa kev xa khoom sai thiab ua tiav cov ntaub ntawv;
Tsis txhob siab - qhov ntsuas kub ib puag ncig: Tso cov khoom ua haujlwm kom txias rau chav tsev kub (<50℃) before measurement to prevent thermal softening from affecting readings;
Calibrate cov cuab yeej ua ntej txhua qhov kev siv: Txheeb xyuas ntawm tus qauv thaiv kom ntseeg tau tias qhov yuam kev tsawg dua lossis sib npaug rau ± 1 HRC, zam kev sib txawv ntawm lub cev.
Txoj Cai Kev Nyab Xeeb: "Qhov tseeb qhov kub thiab txias, muaj pes tsawg qhov kev sim, thiab cov ntaub ntawv khaws cia" kom ua tiav cov txheej txheem tswj thiab rov tsim dua tshiab.
