1. Dab tsi yog tungsten carbide taub hau tuag?

Nrog siab hardness thiab siab dabtsi yog khoov zog, tungsten carbide txias hau tuag yog nias thiab sintered los ntawm hmoov metallurgy. Nws yog dav siv hauv molding thiab fastener-ua teb. Lub tungsten carbide taub hau tuag blanks yog siv los ua lub hauv paus ntsiab lus los nias rau hauv lub tsho hlau. Ua ke nrog lub tsho steel, lub taub hau txias tuag yog hnav-tiv taus thiab ua haujlwm zoo dua, thiab kev pabcuam lub neej tau nce ntau.

2. Cov xwm txheej ua haujlwm

Nyob rau hauv lub zog muaj zog, qhov cuam tshuam kev ntxhov siab ntawm lub punch tuaj yeem ncav cuag ntau dua 2500MPa, qhov chaw ntawm qhov chaw tuag thiab qhov chaw ua haujlwm ntawm cov punch yog ob qho tib si raug cuam tshuam rau kev sib txhuam loj, thiab qhov kub ntawm qhov tsim ntawm qhov chaw yog siab li. 300 ℃. Vim lub ntsej muag tsis sib luag ntawm qhov khoob, lub punch kuj yuav raug khoov kev ntxhov siab. Txias taub hau tuag nyob rau hauv kev cuam tshuam los yog muaj zog cuam tshuam hnav-resistant ua hauj lwm tej yam kev mob, lawv commonality yog tias cov cemented carbide muaj kev cuam tshuam zoo toughness, tawg toughness, qaug zog zog, dabtsi yog khoov zog, thiab zoo hnav tsis kam. Yog li ntau fasteners yog tsim los ntawm txias taub hau tuag.

3. Cov hom tsis ua haujlwm tseem ceeb

Kev hnav ntau dhau rau ntawm qhov chaw ua haujlwm ntawm lub ntsej muag thiab concave tuag, occlusal kev puas tsuaj, hauv zos groove tev tawm, ntxhov siab lossis tawg ntawm cov punch, o lossis tawg ntawm cov tuag, tawg ntawm cov npoo thiab cov fab, thiab lwm yam.

4. Cov kev xav tau ntawm kev ua haujlwm

Lub taub hau txias tuag bears qhov cuam tshuam los ntawm lub taub hau, thiab qhov chaw ua haujlwm ntawm qhov tuag yuav tsum muaj siab hardness thiab hnav tsis kam, thiab cov tub ntxhais muaj lub zog txaus thiab toughness. Yog hais tias lub hardened txheej ntawm lub taub hau txias tuag yog ib qho nyuaj los yog tob heev, cov pwm qhov chaw yuav tawg; ntawm qhov tsis sib xws, qhov chaw ua haujlwm ntawm cov pwm pwm yog yooj yim hnav, thiab cov khoom ntxhib adheres rau pwm qhov chaw. Feem ntau, qhov nyuaj ntawm cov punch yog 60 ~ 62HRC, qhov tuag yog 58 ~ 60HRC, thiab qhov tob ntawm txheej hardened yuav tsum tswj los ntawm 1.5 ~ 4 hli. Lub taub hau txias tuag yog raug rau cov khoom hnyav hnyav, thiab qhov saum npoo ntawm qhov tuag tau raug siab compressive. Cov khoom siv pwm yuav tsum muaj lub zog siab, toughness, thiab hnav tsis kam.


Zhuzhou Better Tungsten Carbide tuam txhab tau tsim tungsten carbide tuag rau ntau tshaj 15 xyoo. Peb muaj ntau txhiab pawg pwm los tsim cov carbide sib txawv.
