cemented carbide yob rings (tseem hu ua tungsten carbide yob nplhaib) muaj cov khoom zoo thermal conduction. Piv nrog rau lwm cov ntaub ntawv, nws zoo dua nyob rau hauv cov nqe lus ntawm tshav kub-tiv taus, hnav-tiv taus thiab lub zog. Dab tsi ntxiv, nws hardness txo me ntsis nyob rau hauv qhov kub thiab txias. Yog li, cov cemented carbide yob rings yog tsim nrog ap-pearance ntawm kev kub ceev hlau qws zeb.With txoj kev loj hlob thiab kev txhim kho, nws yog dav siv nyob rau hauv zus tau tej cov high speed hlau, bar thiab deformed steel bar.
Raws li cov khoom siv rau peb cov khoom, muaj ob series li Wc-Co thiab Wc-Co-Ni-Cr uas muaj cov khoom zoo sib xws. Lub zog dabtsi yog khoov thiab cuam tshuam toughness ncav cuag 2200 Mpa thiab (4-) x106J / m'respectively.Nws hardness thiab hnav tsis kam yog los ntawm tungsten carbide (Wc) thaum lub toughness thiab lub zog nyob ntawm tus neeg sawv cev khi (Co-Ni-Cr). Tam sim no, lub tshuab ua tiav feem ntau yog tsim los ntawm 8-10 sawv ntsug. Vim tias qhov loj ntawm pob txha tawg ntawm qhov dov ib feem, lub dab tshos nyob rau pem hauv ntej ntawm kev ua tiav zeb tuaj yeem tiv taus lub luag haujlwm hnyav thiab muaj zog. Yog li, lub siab hardness thiab zoo thermal qaug zog kuj yog lub hauv paus tseem ceeb, uas yog ua ntej hnav-tiv taus.Thaum muaj qhov tsis tshua muaj load thiab cuam tshuam rau cov khoom siv, peb yuav tsum tau them nyiaj ntau rau qhov hnav-ua hauj thiab thermal qaug zog ntawm yob. nplhaib. Tam sim no, lub tshuab ua tiav feem ntau yog tsim los ntawm 8- 10 stands.Vim tias qhov loj ntawm qhov tawg ntawm qhov dov, lub dab tshos rau pem hauv ntej ntawm cov xov zeb tuaj yeem tiv taus lub luag haujlwm hnyav thiab muaj zog. Yog li, lub siab hardness thiab zoo thermal qaug zog kuj yog thawj yam, uas yog ua ntej hnav-ua hauj. peb yuav tsum xyuam xim rau qhov hnav-tiv taus thiab thermal qaug zog tsis kam ntawm yob rings.
