Dab tsi yog qhov kub thiab txias qhov chaw rau H13 steel?

Rau H13 steel, tempering kub feem ntau yog li ntawm 550 txog 600 degree, nrog 580℃± 5℃yog qhov zoo tagnrho tus nqi. Qhov ntsuas kub no yog cov txheej txheem txheej txheem rau kev ua haujlwm kub tuag hlau vim nws ua tiav qhov sib npaug toughness, hardness, thiab microstructural stability.

1. Tempering kub thiab kev sib raug zoo

Zoo heev hnav tsis kam thiab siab hardness, tab sis marginally txo toughness

Cov qauv siab rau hnav tsis kam thiab qhov xav tau kom tsis txhob brittleness

580℃(tseem ceeb)

49–51

Qhov zoo tagnrho piv ntawm durability, lub zog, thiab tsis kam hnav

Zoo tagnrho rau feem ntau ntawm kev ua haujlwm kub tuag

600 degree

48–50

Txhim kho durability thiab me me matrix softening

Siab - cuam tshuam los yog nyuaj rau kev ntxhov siab

Daim Ntawv Thov: Cov tuam txhab tuag hauv Wuhan nquag siv qhov dej zoo -tsim txheej txheem ntawm tempering ntawm 580℃rau ob teev rau ob lub voj voog. Qhov kub khiav nozzle lub neej muaj peev xwm tshaj 500,000 cycles, thiab ntsuas hardness yog ruaj khov ntawm 49.8 ~ 50.3 HRC.

2. Cov ntsiab lus tseem ceeb ntawm kev tswj qhov kub thiab txias

Nws yog ib qho tsim nyog yuav tsum ua haujlwm PID qhov ntsuas kub thiab xyuas kom meej tias qhov sib txawv ntawm qhov kub ntawm qhov cub thiab qhov ntsuas kub tsawg dua lossis sib npaug li ± 5 degree.

Multi- taw tes ntsuas qhov ntsuas kub ntsuas: Teem qhov tsawg kawg ntawm peb qhov ntsuas kub ntsuas hauv lub cub tawg sab sauv, nruab nrab, qis, thiab kaum cheeb tsam txhawm rau txheeb xyuas qhov kub ntawm qhov sib txawv tsawg dua lossis sib npaug li ± 5℃.

Ua kom tsis txhob muaj qhov kub thiab txias: qhov kub qis dua 550℃tuaj yeem ua rau tsis txaus tempering, uas tuaj yeem ua rau cov tawv nqaij tawv thiab tawv ntau dua 52 HRC.

Tsis txhob overheating: Kub siab tshaj 600℃tuaj yeem ua rau dhau -tempering, uas txo lub zog thiab ua rau lub hardness tsawg dua 48 HRC.

Case Study: Ib qho teeb meem tswj qhov kub thiab txias ua rau lub tuam txhab teeb tsa qhov kub ntawm 530 degree. Cov pob txha tawg tau tshwm sim tom qab tsuas yog peb hnub ntawm kev phais, thiab qhov ntsuas hardness mus txog 53.5 HRC.

3. Txhawb cov txheej txheem lav kev ua haujlwm zoo ib yam

Muab ob npaug rau Tempering: Txhawm rau kom txo qhov seem seem, lub qhov cub yuav tsum cua txias rau chav sov tom qab pib tempering.

Lub sij hawm tuav txaus: Rau cov ntu tuab, ntxiv 30 feeb rau txhua 25 hli tuab. Txhua lub sijhawm tempering yuav tsum kav ntev li ob teev.

Cov txheej txheem sau cia thiab taug qab: Txhawm rau kom ua tiav qhov kaw- kev tswj xyuas qhov zoo, qhov ntsuas kub ntawm lub cub tawg thiab cov ntaub ntawv hardness yog khaws cia rau txhua qhov cub.

Cov Ntsiab Cai Kev Nyab Xeeb: Nws yog ib qho tseem ceeb kom tswj tau qhov kub thiab txias, txaus tus naj npawb ntawm tempering cycles, thiab cov ntaub ntawv teev tseg.
