Qhov zoo tshaj plaws hardness ntawm H13 khoom tom qab tempering yog dab tsi?

Tom qab tempering, qhov zoo tagnrho hardness range rau H13 khoom yog 48-52 HRC. Cov koob no ua kom ntseeg tau cov pwm kev pab cuam nyob rau hauv qhov kub thiab txias qhov xwm txheej los ntawm kev tawm tsam qhov zoo tshaj plaws ntawm lub zog, toughness, thiab hnav tsis kam.

 

1. Kev sib txuas ntawm kev ua tau zoo thiab hardness

Ntau yam ntawm Hardness

Risk ceeb toom

48–52 HRC (qhia)

Ua ke hnav tsis kam thiab cuam tshuam rau kev ua haujlwm zoo tag nrho

Zoo tagnrho rau feem ntau ntawm kub- ua haujlwm pwm

<48 HRC

matrix softening, nce hnav, thiab susceptibility rau vau

Hauv cov xwm txheej siab -, nws tsis raug qhia.52 HRC

Xav txog ntau brittleness thiab muaj feem ntau ntawm cracking

Kev tswj nruj nruj yog yuav tsum tau, thiab nws tsuas yog tsim nyog rau cov kev xav tau tshwj xeeb.

Daim Ntawv Thov: Hauv Wuhan, tempering ntawm 580℃rau ob teev rau ob lub voj voog yog cov txheej txheem txheem. Qhov kub khiav nozzle lub neej muaj peev xwm tshaj 500,000 cycles, thiab qhov tseeb ntsuas hardness yog ruaj khov ntawm 49-51 HRC.

 

2. Yuav ua li cas Hardness tuaj yeem txheeb xyuas tau raws li qhov yuav tsum tau ua? Precise Temperature Control: PID kub tswj qhov system yog siv los teem lub tempering kub ntawm 580℃± 5 degree.

Ob Tempering Cycles: Ua ntej tempering thib ob, cov khoom yuav tsum tau cua txias rau chav sov tom qab thawj tempering.

Lub sij hawm tuav txaus: Txhua lub voj voog tempering kav ntev li ob teev; rau cov khoom tuab, ua kom lub sijhawm tuav los ntawm peb caug feeb rau txhua nees nkaum- tsib millimeters ntawm tuab.

Multi-Point Temperature Measurement Verification: Txhawm rau tiv thaiv kom tsis txhob muaj cua sov hauv cheeb tsam lossis thaj chaw txias, lub qhov cub qhov kub sib txawv yog tsawg dua lossis sib npaug li ± 5℃.

Case Study: Tom qab tsuas yog peb hnub ntawm kev ua haujlwm, ib lub tuam txhab tempering kub qis dhau (530 degree), ua rau lub hardness ntawm 53.5 HRC thiab brittle puas.

 

3. Cov qauv rau kev kuaj Hardness

Ntsuas Point Layout: Txhua feem yog ntsuas ntawm peb mus rau tsib qhov chaw (center, ntug, thiab thickness ciam teb).

Kev lees txais:

48–52 HRC yog tus nqi nruab nrab.

Ntau yam rau Ib Ntu: Tsawg dua lossis sib npaug rau 2 HRC

Cov ntaub ntawv Archiving: Cov ntaub ntawv ntsuas thiab qhov kub ntawm lub cub tawg yog khaws cia rau kev taug qab.
