Yuav ua li cas kom ntseeg tau qhov sib xws ntawm hardness hauv H13 cov khoom

Kev tswj xyuas meej ntawm cov txheej txheem tempering, cov txheej txheem ua kom sov ua kom sov, siv ob txheej txheem tempering, thiab kev sib xyaw ntawm cov khoom siv ua ntej - tshuaj xyuas thiab tag nrho - cov txheej txheem kev soj ntsuam cov ntaub ntawv yog cov tswv yim tseem ceeb rau kev lav qhov sib xws ntawm hardness hauv H13 cov khoom, yog li ua tiav hardness stability ntawm batches thiab nyob rau hauv ib tug neeg daim.

 

1. Cov Txheej Txheem Tseem Ceeb Tswj Cov Ntsiab Lus

Tswj Yam

Kev ntsuas tshwj xeeb

Muaj nuj nqi

Tswj qhov kub thiab txias

Qhov tseeb ntawm 550-600 degree; 580℃+/- 5℃tau qhia.

Kev tswj qhov kub thiab txias yog qhov tseem ceeb vim tias qhov kub hloov pauv ntawm ± 10℃tuaj yeem ua rau lub hardness hloov ntawm 1 ~ 2 HRC.

Qhov ntau ntawm rounds ntawm tempering

Nws yuav tsum tau tempered ob zaug. Ua ntej thib ob tempering, tso cai rau thawj zaug kom txias rau chav sov.

txhawm rau txhim kho microstructure stability thiab nres qhov seem ntawm kev ntxhov siab.

Khaws Sijhawm

Ntau dua lossis sib npaug li 2 teev txhua lub sijhawm. Ntxiv peb caug feeb rau txhua nees nkaum- tsib millimeters ntawm tuab.

los tiv thaiv nto thiab sab hauv irregularities thiab lav txaus tempering ntawm cov tub ntxhais.

Tshuab cua txias

cua txias los ntawm huab cua mus rau chav tsev kub. Tsis pub txias nrog dej lossis roj.

kom tsis txhob localized quenching lossis kev loj hlob ntawm kev ntxhov siab tom ntej.

Siv lub tshuab cua sov uas muaj ntau- ntsuas kub ntsuas thiab PID ntsuas kub. Lub qhov cub qhov kub sib txawv yuav tsum khaws cia ntawm ± 5 degree.

 

2. Optimizing Thermal Circulation thiab Rauv Loading

Tsim nyog qhov sib txawv: Txhawm rau tiv thaiv kev sib tsoo thiab lav qhov sib xws ntawm huab cua kub, khaws qhov tsawg kawg ntawm 5 cm ntawm cov khoom ua haujlwm.

Optimal Positioning: Txhawm rau kom tsis txhob muaj qhov txias txias los ntawm kev cuam tshuam hauv cheeb tsam, hloov ntawm qhov tuab thiab nyias.

Siv Tooling Racks: Txhawm rau kom ruaj khov workpieces thiab txhim khu kev sib hloov ntawm cov cua sov, siv cov kev txhawb nqa uas tuaj yeem tiv taus qhov kub thiab txias.

Enhanced Convection: Txhawm rau kom qhov kub thiab txias sib xws, qhib lub tshuab cua txias lossis cua sov kiv cua.

Cov ntaub ntawv tshawb fawb: Los ntawm kev ua kom lub qhov cub ua kom muaj qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom, Jingmo Technology txo qhov sib txawv hardness ntawm H13 manifold phaj tom qab tempering los ntawm 3.1 HRC rau 1.4 HRC.

 

3. Kaw-Txoj kev saib xyuas thiab kev ua tau zoo

Rauv kub Curve Recording: Kom lav tswj thiab traceable kub, tag nrho cov cua sov thiab txias nkhaus yog kaw rau txhua lub cub tawg.

100% Hardness Testing: Tom qab tempering, lub portable hardness tester nrog ib tug ntau ntawm tsawg dua los yog sib npaug rau 2 HRC yog siv los ntsuam xyuas hardness ntawm peb los yog ntau tshaj qhov chaw ib thooj.

Kev txheeb xyuas ntawm Metallographic Sampling: Txhawm rau kom ntseeg tau tias lub microstructure yog ib yam tempered martensite + tawg carbides, Ntau dua lossis sib npaug li 5% ntawm cov khoom siv yog kuaj.

Raw Khoom Ua Ntej- tshuaj xyuas: XRF yog siv los xyuas kom meej tias Cr (5.0% ~ 5.5%), Mo (1.1% ~ 1.75%), thiab V (0.8% ~ 1.2%) cov khoom ua kom txaus siab ua ntej tempering.

"Qhov kub thiab txias, txaus tus naj npawb ntawm cov ntawv xeem, thiab cov ntaub ntawv khaws cia" yog cov qauv kev nyab xeeb uas lav ua tiav cov txheej txheem traceability thiab rov tsim dua tshiab.
