Tungsten carbide rod is tungsten carbide round bar, inozivikanwawo se tungsten simbi bar, zviri nyore kutaura, tungsten simbi yeraundi bar kana tungsten carbide round bar.Tungsten carbide chinhu chakaumbwa chinogadzirwa nehupfu metallurgy uye inoumbwa nerefractory metal compounds (yakaoma chikamu) uye simbi dzakasungwa (binder chikamu).
Pane nzira mbiri dzekugadzira dzekugadzira tungsten carbide round bars: imwe ndeye extrusion, uye extrusion inzira yakakodzera yekugadzira mbariro refu.Inogona kuderedzwa kune chero hurefu hunodiwa nemushandisi panguva yeextrusion process.Zvisinei, kureba kwese hakugoni kudarika 350mm.Imwe yacho ndeye compression molding, iri nzira yakakodzera yekugadzira short bar stock.Sezvinoratidzwa nezita racho, cemented carbide powder inotsikirirwa kuita chimiro neforoma.
Cemented carbide ine nhevedzano yezvakanakisa zvivakwa zvakaita sekuomarara kwepamusoro, kusapfeka, simba rakanaka uye kuomarara, kushomeka kwekushisa, kushomeka kwekuora, kunyanya kuomarara kwayo kwakanyanya uye kusapfeka, izvo zvinoramba zvisina kushanduka kunyangwe tembiricha ye500 ° C, uye zvakadaro. ine kuoma kwepamusoro pa1000 °C.Tungsten carbide inoshandiswa zvakanyanya semidziyo yekushandisa, senge maturusi ekuchinjisa, milling cutters, planer cutters, drills, boring cutters, nezvimwewo, kucheka simbi yakakandwa, isiri-ferrous simbi, mapurasitiki, kemikari fiber, graphite, girazi, dombo uye zvakajairika. simbi, uye inogonawo kushandiswa kucheka simbi isingadziviriri kupisa, simbi isina tsvina, yakakwirira manganese simbi, mudziyo simbi uye zvimwe zvinhu zvakaoma kunyorova kukuya (bhora chigayo, drying cabinet, Z-mixer, granulator---), kudzvanya (parutivi. pressure hydraulic press or extruder), --- sintering (degreasing furnace, integrated virace kana HIP low pressure furnace).
Zvigadzirwa zvakanyorova kukuya, kuomesa, glue doping, wozoomesa uye kuderedza kushushikana mushure mekuumbwa kana extrusion, uye pakupedzisira kugadzira iyo yekupedzisira alloy isina chinhu nekubvisa uye kunyura.
Iyo yakashata yekutenderera bar extrusion kugadzirwa ndeyekuti kutenderera kwekugadzira kwakareba.Kudzvanya dhayamita diki mativi mbariro pazasi 3mm uye kutyora iyo migumo miviri kunoparadza humwe huwandu hwezvinhu.Iyo yakareba kureba kwekabhidhi diki dhayamita yakatenderedza bar, zvakanyanya kutwasanuka kweiyo isina chinhu.Ehe, kutwasanuka uye kutenderera matambudziko anogona kuvandudzwa necylindrical kugaya pane imwe nguva.
Imwe ndeye compression molding, inova nzira ipfupi bar stock inogadzirwa.Sezvinoratidzwa nezita racho, ndiyo mold inotsikirira simende carbide poda kuita chimiro.Kubatsira kweiyi carbide bar yekugadzira nzira ndeyekuti inogona kuumbwa mune imwechete pass uye inoderedza zvimedu.Rerutsa nzira yekucheka waya uye kubvisa iyo yakaoma zvinhu kutenderera kweiyo extrusion nzira.Iyo iri pamusoro yakapfupikiswa nguva inogona kuchengetedza vatengi 7-10 mazuva.
Kunyatsotaura, isostatic kudzvanya zvakare ndeye compression molding.Isostatic kudzvanya ndiyo yakanakira kuumba nzira yekugadzira yakakura uye refu tungsten carbide kutenderera mabara.Kuburikidza nezvisimbiso zvepamusoro nepasi zvepiston, pombi yekumanikidza inopinza mvura yepakati pakati pe-high-pressure cylinder nerabha yakadzvanywa, uye kudzvanywa kunofambiswa kuburikidza nerabha yakamanikidzwa kuita simende yehupfu yecarbide yakatsikirirwa kugadzira.
