Qhov txawv ntawm YT hom thiab YG hom cemented carbide

Cemented carbide yog hais txog cov khoom siv hlau uas ua los ntawm cov hlau tsis muaj zog li matrix thiab cov hlau hloov pauv raws li qib binder, thiab tom qab ntawd ua los ntawm cov hmoov hlau metallurgy. Nws yog dav siv hauv tsheb, kho mob, tub rog, tiv thaiv lub tebchaws, aerospace, aviation thiab lwm yam kev lag luam. . Nws yog ib nqi sau cia hais tias vim muaj ntau hom thiab cov ntsiab lus ntawm refractory hlau carbide thiab binders, lub cev thiab tshuaj zog ntawm cov cemented carbide npaj kuj txawv, thiab lawv txhua yam thiab lub cev zog feem ntau nyob ntawm seb hom hlau carbide. Raws li cov khoom sib txawv, cemented carbide tuaj yeem muab faib ua YT hom thiab YG hom cemented carbide.
Los ntawm lub ntsiab lus txhais, YT-hom cemented carbide hais txog tungsten-titanium-cobalt-hom cemented carbide, cov khoom tseem ceeb yog tungsten carbide, titanium carbide thiab cobalt, thiab lub npe yog "YT" ("nyuaj, titanium"). ob lo lus Suav Pinyin prefix) Nws yog tsim los ntawm cov ntsiab lus nruab nrab ntawm titanium carbide, xws li YT15, uas txhais tau hais tias qhov nruab nrab cov ntsiab lus ntawm titanium carbide yog 15%, thiab tus so yog cemented carbide nrog tungsten carbide thiab cobalt cov ntsiab lus. YG-hom cemented carbide hais txog tungsten-cobalt-hom cemented carbide. Cov khoom tseem ceeb yog tungsten carbide thiab cobalt. Piv txwv li, YG6 hais txog tungsten-cobalt carbide nrog qhov nruab nrab cobalt ntsiab lus ntawm 6% thiab tus so yog tungsten carbide.
Los ntawm qhov kev ua tau zoo ntawm qhov pom, ob qho tib si YT thiab YG cemented carbides muaj kev sib tsoo zoo, khoov lub zog thiab toughness. Nws yuav tsum raug sau tseg tias qhov hnav tsis kam thiab thermal conductivity ntawm YT-hom cemented carbide thiab YG-hom cemented carbide yog qhov sib txawv. Cov qub tau zoo dua hnav tsis kam thiab tsis zoo thermal conductivity, thaum tom kawg muaj kev hnav tsis zoo thiab thermal conductivity. nws yog qhov zoo. Los ntawm qhov pom ntawm daim ntawv thov, YT hom cemented carbide yog qhov tsim nyog rau kev sib hloov ntawm ntxhib, ntxhib npaj, semi-tiav, ntxhib milling thiab drilling ntawm qhov tsis sib xws thaum qhov tsis sib xws ntawm cov pa roj carbon steel thiab hlau alloy yog sib cais; YG hom nyuaj alloy Nws yog tsim rau ntxhib tig nyob rau hauv nruam txiav ntawm cam khwb cia hlau, uas tsis yog-ferrous hlau thiab lawv cov alloys thiab non-metallic cov ntaub ntawv, semi-tiav thiab tiav nyob rau hauv intermittent txiav.
Muaj ntau tshaj 50 lub teb chaws hauv ntiaj teb uas tsim cov cemented carbide, nrog rau tag nrho cov zis ntawm 27,000-28,000t-. Cov neeg tsim khoom tseem ceeb yog Tebchaws Meskas, Russia, Sweden, Tuam Tshoj, Lub Tebchaws Yelemees, Nyiv, United Kingdom, Fabkis, thiab lwm yam. Lub ntiaj teb cemented carbide kev ua lag luam yog qhov pib saturated. , kev lag luam kev sib tw yog nruj heev. Tuam Tshoj txoj kev lag luam cemented carbide tau pib zoo nyob rau xyoo 1950s. Txij xyoo 1960 mus txog xyoo 1970, Tuam Tshoj txoj kev lag luam cemented carbide tau tsim sai heev. Nyob rau hauv thaum ntxov 1990s, Tuam Tshoj tus tag nrho cov peev xwm ntawm cemented carbide mus txog 6000t, thiab tag nrho cov khoom ntawm cemented carbide mus txog 5000t, thib ob tsuas yog nyob rau hauv Russia thiab lub tebchaws United States, nws nyob rau hauv peb lub ntiaj teb no.
