Yuav ua li cas txhawm rau txhawm rau txhawm rau txhawm rau ntsuas kub thaum lub sijhawm tempering ntawm H13 cov khoom

Ua raws li qhov ntsuas kub ntau - taw tes ntsuas, ntsuas qhov ntsuas qhov ntsuas qhov ntsuas, thiab ua qhov ntsuas qhov ntsuas kub tsis sib xws (TUS) txhawm rau tswj qhov kub ntawm qhov sib txawv hauv qhov cub kom tsawg dua lossis sib npaug li ± 5℃yog tus yuam sij kom ua kom lub qhov cub zoo sib xws thaum tempering ntawm H13 khoom. Qhov no ua kom muaj kev ua haujlwm zoo ib yam ntawm cov khoom ua haujlwm hauv tib batch.

 

1. Kev tswj hwm qhov tseem ceeb

Muaj nuj nqi

Kev txheeb xyuas ntawm Multi-point Temperature Measurements

Rau qhov tiag- kev saib xyuas lub sijhawm, tso qhov tsawg kawg yog rau qhov ntsuas qhov ntsuas kub hauv lub qhov cub rau sab sauv, nruab nrab, qis, pem hauv ntej, nram qab, thiab cov ces kaum.

Xyuas kom tseeb tias qhov sib txawv ntawm qhov kub thiab txias yog tsawg dua lossis sib npaug rau ± 5℃los ntawm kev ntes cov chaw txias thiab kub.

Standardized Method rau cub Loading

Qhov sib nrug ntawm qhov workpiece yuav tsum yog tsawg kawg 5 cm; minimize stacking; thiab siv cov khoom siv uas tuaj yeem tiv taus qhov kub thiab txias.

Txhim kho qhov ua tau zoo ntawm cov cua kub ncig thiab zam kom tsis txhob muaj cua sov hauv zos.

Tswj Segmented Cua sov

Thaum qhov kub thiab txias qis dua 400 degree, tsa nws maj mam (tsawg dua lossis sib npaug li 150℃/ h) kom txo qis thermal stress thiab kub hloov pauv ib ntus.

Tiv thaiv qhov chaw ua haujlwm ntawm qhov chaw thiab cov tub ntxhais los ntawm kev muaj qhov sib txawv ntawm qhov kub thiab txias uas tuaj yeem ua rau asynchronous microstructure hloov pauv.

UAS Examinations

Ntsuam xyuas qhov kub thiab txias sib xws ntawm lub qhov cub hauv peb lub hlis twg raws li AMS 2750.

Txheeb xyuas qhov ruaj khov ntawm cov khoom siv thiab pom sai sai pom muaj teeb meem nrog kev laus lossis thermocouple drift.

Piv txwv li: Jingmo Technology tau siv ntau - cheeb tsam kub- tswj lub cub tawg thiab kev teeb tsa kev teeb tsa kom txo qis qhov sib txawv ntawm H13 manifold los ntawm 2.8 HRC rau 1.2. Cov batch pass tus nqi ntawm HRC tau nce mus rau 99.2%.

 

2. Tej yam tshwm sim ntawm qhov tsis ua hauj lwm nyob rau hauv qhov kub thiab txias uniformity:

Dispersed hardness faib nyob rau hauv tib lub workpiece los yog batch: Hardness txawv> 2 HRC;

Inconsistent microstructure: Metallographic tshawb nrhiav pom coarsened carbides nyob rau hauv qee qhov chaw thiab untempered martensite nyob rau hauv lwm tus;

Kev pabcuam tsis ua haujlwm thaum ntxov: Kev ntxhov siab nyob rau hauv "qhov chaw mos" lossis "qhov chaw nyuaj" ua rau thaj chaw tawg lossis ua kom nrawm nrawm.

Cov ntaub ntawv ceeb toom: Vim muaj kev puas tsuaj rau lub qhov cub hluav taws xob hauv qab txheej txheej, qhov kub ntawm qhov chaw ua haujlwm hauv qab (uas yuav tsum yog 580 degree) tsuas yog 568 degree. Qhov no ua rau lub hardness tsawg li 47.8 HRC, uas txhais tau hais tias tag nrho cov khoom raug tsis lees paub.

 

3. Mechanism rau ntev -lub sij hawm lav

Tsim cov txheej txheem archives: txhawm rau pab txhawb kev taug qab, ua kom tiav cov cua sov thiab txias nkhaus thiab cov ntaub ntawv ntsuas kub tau khaws cia rau txhua qhov cub.

Kev ntsuas cov cuab yeej nquag: txhawm rau lav cov ntaub ntawv raug, cov thermocouples thiab cov tswj ntsuas kub tau ntsuas txhua peb lub hlis;
