Cemented carbide wani gami abu ne da aka yi da wuya mahadi na refractory karafa da bonding karafa ta foda karfe tsari.Yawancin lokaci ana yin shi da kayan haɗin kai masu laushi (kamar cobalt, nickel, ƙarfe ko cakuda abubuwan da ke sama) da kayan aiki masu wuya (kamar tungsten carbide, molybdenum carbide, tantalum carbide, chromium carbide, vanadium carbide, titanium carbide ko su). cakuda).
Cemented carbide yana da jerin kyawawan kaddarorin, irin su babban taurin, sa juriya, ƙarfi mai kyau da tauri, juriya mai zafi, juriya na lalata, da sauransu, musamman ma girman taurin sa da juriya, wanda ya kasance mai canzawa ko da a 500 ℃ kuma har yanzu yana da. high taurin a 1000 ℃.A cikin kayanmu na yau da kullun, taurin yana daga sama zuwa ƙasa: lu'u-lu'u mai laushi, cubic boron nitride, cermet, carbide cemented, ƙarfe mai sauri, kuma taurin yana daga ƙasa zuwa babba.
Cemented carbide ne yadu amfani da yankan kayan aiki kayan, kamar juya kayan aikin, milling cutters, planers, rawar soja rago, m cutters, da dai sauransu, domin yankan jefa baƙin ƙarfe, wadanda ba ferrous karafa, robobi, sinadaran zaruruwa, graphite, gilashin, dutse da kuma karfe na yau da kullun, haka kuma don yankan karfe mai jure zafi, bakin karfe, babban karfen manganese, karfen kayan aiki da sauran kayan injin.
Carbide da aka yi da siminti yana da tsayin daka, ƙarfi, juriya da juriya na lalata, kuma ana kiransa da "haƙoran masana'antu".Ana amfani da shi don kera kayan aikin yanke, kayan aikin yanke, kayan aikin cobalt da sassa masu jurewa.Ana amfani da shi sosai a masana'antar soji, sararin samaniya, injina, karafa, hako mai, kayan aikin hakar ma'adinai, sadarwar lantarki, gine-gine da sauran fannoni.Tare da haɓaka masana'antu na ƙasa, buƙatun kasuwa na simintin carbide yana ƙaruwa.Kuma a nan gaba, kera makamai da kayan aiki na zamani, ci gaban kimiyya da fasaha da kuma saurin bunkasuwar makamashin nukiliya za su kara yawan bukatar kayayyakin siminti na siminti tare da fasahar kere-kere da kwanciyar hankali mai inganci. .
A cikin 1923, schlerter na Jamus ya ƙara 10% - 20% cobalt zuwa tungsten carbide foda a matsayin mai ɗaure, kuma ya ƙirƙira sabon gami na tungsten carbide da cobalt.Taurinsa shine na biyu kawai bayan lu'u-lu'u, wanda shine carbide na farko da aka yi da siminti a duniya.Lokacin yankan karfe tare da kayan aikin da aka yi da wannan gami, ruwan zai yi sauri da sauri, har ma da ruwan wukake zai tsage.A shekara ta 1929, Schwarzkov na Amurka ya ƙara wani adadin fili na tungsten carbide da titanium carbide zuwa ainihin abun da ke ciki, wanda ya inganta aikin kayan aikin yanke karfe.Wannan wata nasara ce a tarihin ci gaban siminti na siminti.
Hakanan za'a iya amfani da simintin carbide don yin kayan aikin hako dutse, kayan aikin hakar ma'adinai, kayan aikin hakowa, kayan aikin aunawa, sassa masu juriya, abrasives na ƙarfe, layin silinda, madaidaiciyar bearings, nozzles, gyare-gyaren kayan aiki (kamar ƙirar zanen waya, ƙwanƙwasa ƙura, goro, goro. molds, da daban-daban fastener molds The kyakkyawan aiki na siminti carbide ya maye gurbin baya karfe molds).
A cikin shekaru ashirin da suka gabata, simintin siminti shima ya bayyana.A cikin 1969, Sweden ta sami nasarar haɓaka kayan aiki mai rufi na titanium carbide.Tushen kayan aikin shine tungsten titanium cobalt cimined carbide ko tungsten cobalt cimined carbide.Kauri na titanium carbide shafi a kan surface ne kawai 'yan microns, amma idan aka kwatanta da gami kayan aikin da iri guda iri, da sabis rayuwa yana kara da sau 3, da yankan gudun ya karu da 25% - 50%.Ƙarni na huɗu na kayan aikin shafa sun bayyana a cikin 1970s, waɗanda za a iya amfani da su don yanke kayan da ke da wuyar inji.
