Cemented carbide yog hais txog ib qho khoom siv alloy ua los ntawm refremory hlau compound li binder theem, thiab tom qab ntawd ua los ntawm hmoov metallurgy txoj kev. Nws yog dav siv nyob rau hauv tsheb, kev kho mob, kev ua tub rog, kev tiv thaiv hauv tebchaws, Aerospace, aviation thiab lwm thaj teb. Cov. Nws yog tsim nyog sau tseg tias vim muaj ntau hom thiab cov ntsiab lus ntawm refracted hlau carbides kuj txawv, thiab lawv lub cev thiab lub cev thiab lub cev thiab lub cev ua haujlwm tsuas yog nyob ntawm hom hlau carbide. Raws li cov khoom sib txawv ntawm cov khoom sib txawv, tso cai carbide tuaj yeem faib ua yt hom thiab yg hom cemented carbide.
Los ntawm cov lus txhais ntawm kev pom, yt hom cemeded Ob Txhais Lus Suav Pinyin Ua Ntej) Nws yog tsim ntawm cov ntsiab lus nruab nrab ntawm titanium carbide, uas txhais tau tias cov ntsiab lus ntawm lub carbide yog 15%, thiab so kom zoo nkauj carbide nrog tungsten carbide thiab cob cov ntsiab lus carbide thiab cobalt cov ntsiab lus. YG-hom cemented carbide yog hais txog tungsten-cobalal-ca cemeded carbide. Lub hauv paus tseem ceeb yog tungsten carbide thiab cobalt. Piv txwv li, YG6 yog hais txog tungsten-cobalal carbide nrog qhov nruab nrab cobalt cov ntsiab lus ntawm 6% thiab tus so yog tungsten carbide.
Los ntawm kev ua yeeb yam pom, ob qho tib si yt thiab yg cemented carbides muaj kev sib tsoo zoo, khoov zog thiab tawv. Nws yuav tsum tau sau tseg tias cov hnav tsis kam thiab thermal conductivity ntawm yt-hom cemented carbide thiab yg-hom cemented carbide yog rov qab. Tus qub tau hnav zoo dua hnav thiab tsis zoo thermal conductivity, thaum lub tom kawg muaj kev coj tsis zoo thiab thermal conductivity. Nws yog qhov zoo. Los ntawm qhov kev pom ntawm daim ntawv thov, YT hom cemented carbide yog tsim nyog rau seem ntawm cov hlau thiab tawv nqaij tawv, sib zog ntawm cov hlau thiab cov hlau txiav sib quas sib npaug; YG hom nyuaj alloy Nws yog qhov haum rau ntxhuam kev txiav cov hlau, cov khoom siv tsis yog cov hlau thiab cov ntaub ntawv tsis sib xws thiab ua tiav rau hauv cov ntawv sib quas ntus txiav.
Muaj ntau tshaj 50 lub teb chaws nyob hauv lub ntiaj teb uas tsim cemented carbide, nrog tag nrho cov khoom tawm ntawm 27,000-28,000-. Cov neeg tsim khoom loj yog Tebchaws Asmeskas, Russia, Sweden, Tebchaws Yelemees, Tebchaws Asmeskas, Tebchaws Asmeskas, Asmeskas Kev cem ntuj ua lag luam carbide ua lag luam yog , kev sib tw ua lag luam yog tsiv heev. Tuam Tshoj txoj cai cemented carbide kev lag luam tau pib ua rau cov duab thaum xyoo 1950s. Txij xyoo 1960s rau xyoo 1970, Tuam Tshoj cov cemented carbide kev lag luam tsim sai. Thaum ntxov xyoo 1990s, Tuam Tshoj tag nrho cov khoom muaj peev xwm ntau ntawm 5000tt, thiab tag nrho cov khoom tso tawm ntawm cov cemented carbide mus txog 6000t, thiab tag nrho cov khoom noj thiab cov tebchaws thib peb hauv ntiaj teb.
