Cemented carbide uye high-speed simbi zvinowanzoitika kuzasi kwerukova zvigadzirwa zve refractory metal tungsten (W), zvose zvine zvakanaka thermodynamic properties, uye zvinogona kushandiswa kugadzira midziyo yekucheka, inotonhora-inoshanda mold uye inopisa-kushanda molds, nezvimwewo, nekuda kwe iwo akasiyana maumbirwo ezvinyorwa zveaviri, iwo zvakare akasiyana maererano nemakanika zvivakwa uye mashandisiro.
1. Pfungwa
Cemented carbide ialloy material inoumbwa nerefractory metal carbide senge tungsten carbide (WC) poda uye bonding metal senge cobalt poda. Zita reChirungu rinonzi Tungsten Carbide/Cemented Carbide. Yayo yepamusoro-temperature carbide content yakakwira kupfuura iyo ye-high-speed simbi kureba kwe.
Simbi yepamusoro-soro isimbi yakakwira-carbon yakakwira-alloy simbi inoumbwa nehuwandu hwakawanda hwetungsten, molybdenum, chromium, cobalt, vanadium nezvimwe zvinhu, zvinonyanya kuumbwa nesimbi carbides (senge tungsten carbide, molybdenum carbide kana vanadium carbide) uye simbi matrix, ine carbon content ye 0.7% -1.65%, iyo yakazara huwandu hwe alloying elements i10% -25%, uye zita rechirungu rinonzi High Speed Steels (HSS).
2. Kuita
Ose ari maviri ane hunhu hwekuoma kwepamusoro, kusimba kwepamusoro, kusimba kwakanaka, kuomarara kwakatsvuka, kupfeka kuramba, kupisa kupisa uye kuita kwemaitiro, uye aya maitiro achave akasiyana nekuda kwemagiredhi akasiyana. Kazhinji kutaura, kuomarara, kuomarara kwakatsvuka, kupfeka kuramba uye kupisa kupisa kwecemented carbide zviri nani pane izvo zvekumhanya simbi.
3. Tekinoroji yekugadzira
Maitiro ekugadzira simende carbide anonyanya kusanganisira poda metallurgy process, jekiseni rekuumba tekinoroji kana 3D kudhinda maitiro.
Nzira dzekugadzira dzesimbi inomhanya kwazvo dzinosanganisira tekinoroji yekukandira, tekinoroji ye electroslag remelting, tekinoroji yepoda metallurgy uye tekinoroji yekuumba jekiseni.
4. Shandisa
Kunyangwe ese ari maviri achigona kugadzira mapanga, kupisa basa mold uye inotonhora yekushanda molds, kuita kwavo kwakasiyana. Iyo yekumhanya yekucheka yeakajairwa carbide maturusi akapetwa ka4-7 kupfuura ayo akajairwa akakwira-kumhanya simbi maturusi, uye hupenyu hwesevhisi hurefu hwakapetwa ka5-80. Panyaya yezviumbwa, hupenyu hwesemented carbide inofa ndeye 20 kusvika ku150 nguva dzakakwirira kudarika iyo yesimbi inomhanya inofa. Semuenzaniso, hupenyu hwebasa hwekupisa musoro extrusion inofa yakagadzirwa nesimbi ye3Cr2W8V i5,000 nguva. Iko kushandiswa kweiyo inopisa musoro extrusion inofa yakagadzirwa neYG20 cemented carbide Hupenyu hwesevhisi ndeye 150,000 nguva.
