Carbide ya simenti imagawidwa mu tungsten-cobalt, tungsten-titaniyamu, tungsten-titanium-tantalum-cobalt. Tungsten, cobalt, ndi titaniyamu ndi brittle hard alloys.
1. Zida zodulira carbide za Tungsten-cobalt zikuphatikizapo YG6, YG8, YG8N, ndi zina zotero. Mitundu ya zida zodula carbide ndizoyenera kukonza zitsulo zopanda chitsulo, zitsulo zosapanga dzimbiri, chitsulo chosungunuka, ndi zipangizo zina;
2. Zida zodula za Tungsten ndi titaniyamu zikuphatikizapo YT5, YT15, ndi zina zotero. Chida chodula cha carbide ndi choyenera pokonza zipangizo zolimba monga zitsulo;
3. Zida zodula za Tungsten-titaniyamu-tantalum-cobalt zikuphatikizapo: YW1, YW2, YS25, WS30, etc. Mtundu uwu wa chida chodula carbide ndi choyenera pokonza zipangizo zovuta ku makina monga zitsulo zosagwira kutentha, manganese apamwamba. chitsulo, chitsulo chosapanga dzimbiri, etc.
Makhalidwe amachitidwe a simenti carbide
1. Kuuma kwakukulu (86 ~ 93HRA, kofanana ndi 69 ~ 81HRC);
2. Good matenthedwe kuuma (akhoza kufika 900 ~ 1000 ℃, kusunga 60HRC);
3. Good kuvala kukana.
Zida zodulira Carbide zimakhala ndi liwiro lodulira la 4 mpaka 7 kuposa chitsulo chothamanga kwambiri komanso moyo wa chida womwe ndi nthawi 5 mpaka 80. Popanga nkhungu ndi zida zoyezera, moyo wautumiki ndi nthawi 20 mpaka 150 kuposa chitsulo cha alloy tool. Itha kudula zida zolimba ndi pafupifupi 50HRC. Komabe, carbide yopangidwa ndi simenti ndi yolimba kwambiri ndipo siyingasinthidwe. Ndizovuta kupanga chida chophatikizika chowoneka bwino. Chifukwa chake, masamba amawonekedwe osiyanasiyana nthawi zambiri amapangidwa ndikuyika pazida za thupi kapena nkhungu pogwiritsira ntchito kuwotcherera, kulumikiza, kumangirira makina, ndi zina zambiri.
Gulu la simenti ya carbide
1. Tungsten-cobalt carbide
Zigawo zazikuluzikulu ndi tungsten carbide (WC) ndi binder cobalt (Co). Dzina lake limapangidwa ndi "YG" (pinyin yoyamba yaku China ya "hard, cobalt") komanso kuchuluka kwa pafupifupi cobalt. Mwachitsanzo, YG8 ikutanthauza kuti pafupifupi WCo=8% ndipo yotsalayo ndi tungsten carbide tungsten cobalt carbide. Nthawi zambiri, ma aloyi a tungsten-cobalt amagwiritsidwa ntchito makamaka pazida zodulira carbide, nkhungu, ndi zinthu za geological ndi mineral.
2. Tungsten titaniyamu cobalt carbide
Zigawo zazikuluzikulu ndi tungsten carbide, titanium carbide (TiC), ndi cobalt. Mtundu wake uli ndi "YT" (chiyambi cha pinyin yaku China ya "hard and titaniyamu") komanso zomwe zili mu titanium carbide. Mwachitsanzo, YT15 imatanthauza pafupifupi TiC=15%, ndipo yotsalayo ndi tungsten titanium cobalt simenti ya carbide yokhala ndi tungsten carbide ndi cobalt.
3. Tungsten titanium tantalum (niobium) carbide
Zigawo zazikuluzikulu ndi tungsten carbide, titanium carbide, tantalum carbide (kapena niobium carbide), ndi cobalt. Mtundu uwu wa carbide wopangidwa ndi simenti umatchedwanso universal cemented carbide kapena universal cemented carbide. Dzina lake lili ndi "YW" (chiyambi cha pinyin cha ku China cha "hard" ndi "wan") kuphatikiza nambala ya siririyo, monga YW1.
