Lub ntsiab lus tseem ceeb twg yog qhov nyuaj tshaj plaws los tswj hauv tempering nkhaus ntawm H13 khoom?

The temperature homogeneity inside the furnace is the most challenging essential point to control in the tempering curve of H13 material. The hardness difference of workpieces in the same batch will exceed the standard (>2 HRC) txawm tias muaj qhov kub thiab txias yog tias muaj qhov sib txawv ntawm qhov kub thiab txias (piv txwv li, kub rau saum thiab txias dua hauv qab, lossis qhov kub tsis sib xws ntawm cov ces kaum), uas yuav cuam tshuam rau kev ua tau zoo sib xws.

 

1. Dab tsi ua rau kev tswj qhov kub thiab txias yog qhov nyuaj tshaj plaws? Factors & Yog vim li cas:

Cov cuab yeej laus muaj qhov cuam tshuam loj: Hauv cov cua sov laus, cov thermocouple drift thiab cov txheej txheem rwb thaiv tsev puas tuaj yeem ua rau muaj qhov sib txawv ntawm qhov kub thiab txias uas nyuaj rau txheeb xyuas lub sijhawm.

Workpiece stacking los yog qhov sib nrug ntawm tsawg dua 5 cm tuaj yeem cuam tshuam cov cua sov, uas ua rau "qhov chaw txias" thiab "kub zones." Qhov no ua rau lub Hoobkas loading txoj kev rhiab heev.

Kev ntsuas kub tsis txaus: Tsuas yog ua kom lub qhov muag ntawm lub qhov cub qhov cub qhov nruab nrab qhov kub tsis yog qhov ntsuas kub ntawm cov ces kaum lossis hauv qab.

Cov cua kub tsis sib xws thiab cua txias: Thaum cua sov sai, cov tub ntxhais yuav siv sij hawm ntev kom muaj qhov kub thiab txias tshaj qhov saum npoo, uas ua rau muaj qhov tsis sib xws ib ntus.

Tiag -world Piv txwv: Ib lub thawv rauv thaum ub tau siv nyob rau hauv ib lub Hoobkas. Cov workpieces hauv qab tsuas yog ntsuas ntawm 568 degree, uas ua rau lub hardness poob ntawm 50.2 HRC rau 47.8 HRC txawm tias tau teem rau 580 degree. Yog li ntawd, tag nrho cov batch raug puas tsuaj.

 

2. Sib piv qhov nyuaj ntawm kev tswj qhov kub thiab txias tsis sib xws

Cov ntsiab lus tseem ceeb

Ua rau

Uniformity ntawm qhov cub kub

Feem ntau muab zais thiab cuam tshuam los ntawm ntau qhov sib txawv, xws li cov khoom siv hauv cub tawg, cov khoom siv, thiab ntsuas qhov ntsuas kub

Kho qhov kub thiab txias

PID systems tuaj yeem teeb tsa tau meej, tab sis lawv yuav tsum tau ntsuas raws li niaj zaus.

Qhov ntau ntawm temperings

Yooj yim rau ua; ib qho kev ua; tsis muaj txoj hauv kev tsis tu ncua

Khaws Sijhawm

Cov mis ntshiab kom nce lub sij hawm tuav rau tuab qhov chaw thiab tswj programmable

Core Challenge: Qhov teeb meem ntawm qhov ntsuas kub tsis sib xws yuav tsum muaj cov cuab yeej sib koom ua ke, txheej txheem, thiab kev txhim kho kev ua haujlwm.

 

3. Cov kauj ruam ua tau los txhawb qhov sib xws

Multi- ntsuas qhov ntsuas kub ntsuas qhov ntsuas: txhawm rau lav qhov ntsuas qhov kub ntawm qhov sib txawv tsawg dua lossis sib npaug li ± 5 degree, qhov chaw siab dua lossis sib npaug rau 6 qhov ntsuas kub ntsuas hauv lub qhov cub sab sauv, nruab nrab, qis, pem hauv ntej, nraub qaum, thiab kaum;

Standardized furnace loading: minimize direct stacking, siv tooling racks robust kom kub, thiab chaw workpieces tsawg kawg yog 5 cm sib nrug;

Kev ntsuas qhov kub thiab txias (TUS): Ua raws li peb lub hlis twg thiab ntsuas raws li AMS 2750 tus qauv;

Segmented cua sov tswj: Txhawm rau txo qis kev ntxhov siab thiab qhov kub thiab txias, maj mam nce qhov kub (tsawg dua lossis sib npaug li 150℃/ h) thaum nws qis dua 400 degree.
