Cemented carbide imatanthawuza chinthu cha aloyi chopangidwa ndi chitsulo chosungunuka ngati matrix ndi chitsulo chosinthira ngati gawo lomangira, kenako chimapangidwa ndi njira ya zitsulo za ufa. Amagwiritsidwa ntchito kwambiri pamagalimoto, zamankhwala, zankhondo, chitetezo cha dziko, zamlengalenga, zandege ndi zina. . Ndikoyenera kudziwa kuti chifukwa cha mitundu yosiyanasiyana ndi zomwe zili mu carbides ndi zomangira zachitsulo, zinthu zakuthupi ndi zamankhwala zama carbide opangidwa ndi simenti ndizosiyananso, ndipo zida zawo zamakina ndi zakuthupi zimadalira mtundu wa carbide yachitsulo. Malinga ndi zigawo zikuluzikulu zosiyanasiyana, simenti carbide akhoza kugawidwa mu YT mtundu ndi YG simenti carbide.
Pakutanthauzira, mtundu wa YT simenti carbide umatanthawuza tungsten-titanium-cobalt-mtundu cemented carbide, zigawo zikuluzikulu ndi tungsten carbide, titanium carbide ndi cobalt, ndipo dzina la mtundu ndi "YT" ("hard, titanium" mawu awiri Chinese Pinyin prefix) Amapangidwa ndi titanium carbide, monga YT15, zomwe zikutanthauza kuti titanium carbide ndi 15%, ndipo yotsalayo ndi carbide yomata yokhala ndi tungsten carbide ndi cobalt. YG-mtundu wa simenti carbide amatanthauza tungsten-cobalt-mtundu simenti carbide. Zigawo zazikuluzikulu ndi tungsten carbide ndi cobalt. Mwachitsanzo, YG6 imatanthawuza tungsten-cobalt carbide yokhala ndi cobalt pafupifupi 6% ndipo yotsalayo ndi tungsten carbide.
Kuchokera pamawonedwe, ma carbides onse a YT ndi YG ali ndi ntchito yabwino yogaya, mphamvu yopindika komanso kulimba. Zindikirani kuti kukana kuvala komanso kutenthetsa kwamafuta amtundu wa YT-symented carbide ndi YG-type cemented carbide ndizosiyana. Yoyamba imakhala ndi kukana kovala bwino komanso kusayenda bwino kwamafuta, pomwe chomalizacho chimakhala ndi kukana kovala bwino komanso kusinthasintha kwamafuta. ndi zabwino. Kuchokera pamawonedwe ogwiritsira ntchito, YT mtundu wa cemented carbide ndi woyenera kutembenuza movutikira, kukonza movutikira, kumaliza pang'onopang'ono, mphero yachabechabe ndi kubowola pamtunda wosasunthika pomwe gawo losagwirizana la chitsulo cha kaboni ndi chitsulo cha aloyi limadulidwa modukiza; YG mtundu wolimba aloyi Ndioyenera kutembenuka movutikira pakudula kosalekeza kwa chitsulo chosapanga dzimbiri, zitsulo zopanda chitsulo ndi ma aloyi awo ndi zinthu zopanda zitsulo, kutsirizitsa theka ndikumaliza kudula kwapakatikati.
Pali mayiko opitilira 50 padziko lapansi omwe amapanga simenti ya carbide, yomwe ili ndi 27,000-28,000t-. Opanga kwambiri ndi United States, Russia, Sweden, China, Germany, Japan, United Kingdom, France, ndi zina zotero. Msika wa carbide wopangidwa ndi simenti wapadziko lonse umakhala wodzaza. , mpikisano wamsika ndi woopsa kwambiri. Makampani opanga simenti a carbide ku China adayamba kupanga chakumapeto kwa zaka za m'ma 1950. Kuyambira cha m’ma 1960 mpaka m’ma 1970, makampani opanga simenti a carbide ku China anakula mofulumira. Kumayambiriro kwa zaka za m'ma 1990, kuchuluka kwa kupanga kwa carbide ku China kunafika pa 6000t, ndipo chiwerengero cha carbide chopangidwa ndi simenti chinafika 5000t, chachiwiri ku Russia ndi United States, chili pachitatu padziko lonse lapansi.
