Tungsten carbide sandar tungsten carbide mashaya ce, kuma aka sani da tungsten karfe mashaya, mai sauƙin faɗi, tungsten karfe zagaye mashaya ko tungsten carbide zagaye mashaya.Tungsten carbide wani abu ne mai haɗaka wanda aka samar ta hanyar ƙarfe na foda kuma ya ƙunshi mahadi na ƙarfe na ƙarfe (lokaci mai wuya) da ƙarfe masu ɗaure (lokacin ɗaure).
Akwai hanyoyi guda biyu don samar da sandunan tungsten carbide zagaye: daya shine extrusion, kuma extrusion hanya ce mai dacewa don samar da sanduna masu tsayi.Ana iya yanke shi zuwa kowane tsayin da mai amfani ke so yayin aiwatar da extrusion.Duk da haka, gaba ɗaya tsawon ba zai iya wuce 350mm ba.Sauran kuma shine gyare-gyaren matsawa, wanda shine hanya mai dacewa don samar da gajeren kayan katako.Kamar yadda sunan ke nunawa, ana matse foda mai siminti a cikin siffa tare da mold.
Cemented carbide yana da jerin kyawawan kaddarorin irin su babban taurin, sa juriya, ƙarfi mai kyau da tauri, juriya mai zafi, juriya na lalata, musamman ma girman taurin sa da juriya, wanda ya kasance ba canzawa ko da a zazzabi na 500 ° C, kuma har yanzu yana da babban taurin a 1000 ° C.Tungsten carbide ana amfani da ko'ina azaman kayan aiki, kamar kayan aikin juyawa, masu yankan milling, masu yankan planer, drills, masu yankan guntuwa, da sauransu, don yankan simintin ƙarfe, ƙarfe mara ƙarfe, robobi, fibers sunadarai, graphite, gilashin, dutse da talakawa. karfe, kuma za a iya amfani da su yanke zafi-resistant karfe, bakin karfe, high manganese karfe, kayan aiki karfe da sauran wuya kayan rigar nika (ball niƙa, bushewa hukuma, Z-mixer, granulator ---), latsa (tare da gefe). matsa lamba na'ura mai aiki da karfin ruwa latsa ko extruder), --- sintering (degreasing makera, hadedde makera ko HIP low matsa lamba tanderu).
Abubuwan da ake amfani da su sune rigar niƙa, bushewa, manne doping, sa'an nan bushewa da rage damuwa bayan gyare-gyare ko extrusion, kuma a ƙarshe suna samar da alloy na ƙarshe ta hanyar debinding da sintering.
Rashin hasara na zagaye mashaya extrusion samar shi ne cewa samar da sake zagayowar ne dogon.Matsi ƙananan sanduna zagaye da ke ƙasa da 3mm da karya ƙarshen biyun zai ɓata wani adadin abu.Tsawon tsayin ɗan ƙaramin diamita na carbide, mafi muni da madaidaiciyar madaidaicin.Tabbas, ana iya inganta matsalolin madaidaiciya da zagaye ta hanyar niƙa cylindrical a mataki na gaba.
Wani kuma shine gyare-gyaren matsawa, wato hanyar da ake samar da gajerun jari.Kamar yadda sunan ke nunawa, gyambon ne ke matse foda mai siminti ta siminti.Amfanin wannan hanyar samar da sandunan carbide shine cewa ana iya ƙirƙirar ta a cikin fasfo ɗaya kuma yana rage tarkace.Sauƙaƙe tsarin yanke waya kuma kawar da busasshen zagayowar hanyar extrusion.The sama taqaitaccen lokaci zai iya ajiye abokan ciniki 7-10 kwanaki.
A taƙaice magana, latsa isostatic shima yana cikin gyare-gyaren matsawa.Isostatic latsa hanya ce mai kyau don samar da manyan sandunan tungsten carbide masu tsayi da tsayi.Ta hanyar hatimin fistan na sama da na ƙasa, famfo mai matsa lamba yana shigar da matsakaicin ruwa tsakanin babban silinda mai ƙarfi da roba mai matsa lamba, kuma ana ɗaukar matsa lamba ta hanyar roba mai matsa lamba don yin foda mai simintin carbide da aka matse a cikin kafa.
