Tungsten carbide rod ke tungsten carbide round bar, e tsejoang hape e le tungsten steel bar, ho bonolo ho e bua, tungsten steel round bar kapa tungsten carbide round bar.Tungsten carbide ke thepa e kopantsoeng e hlahisoang ke metallurgy ea phofo 'me e entsoe ka metsoako ea tšepe ea refractory (mohato o thata) le litšepe tse kopantsoeng (mohato o kopanyang).
Ho na le mekhoa e 'meli ea ho etsa mekhoa ea ho hlahisa mekoallo ea tungsten carbide: e' ngoe ke extrusion, 'me extrusion ke mokhoa o loketseng oa ho hlahisa mekoallo e telele.E ka fokotsoa ho bolelele bofe kapa bofe bo lakatsehang ke mosebelisi nakong ea ts'ebetso ea extrusion.Leha ho le joalo, bolelele ba kakaretso bo ke ke ba feta 350mm.E 'ngoe ke compression molding, e leng mokhoa o loketseng oa ho hlahisa lihlahisoa tse khutšoanyane tsa bar.Joalo ka ha lebitso le fana ka maikutlo, phofo ea carbide e samente e hatelloa hore e be sebopeho ka hlobo.
Carbide e entsoeng ka samente e na le letoto la lintho tse ntle tse kang boima bo phahameng, ho hanyetsa ho roala, matla a matle le ho tiea, ho hanyetsa mocheso, ho hanyetsa kutu, haholo-holo boima ba eona bo phahameng le ho hanyetsa ho apara, e lulang e sa fetohe esita le mocheso oa 500 ° C, 'me e ntse e le teng. e na le boima bo phahameng ho 1000 °C.Tungsten carbide e sebelisoa haholo e le lisebelisoa tsa lisebelisoa, joalo ka lithulusi tse fetolang, li-milling cutters, li-planer cutters, li-drill, li-cutters tse boring, joalo-joalo, bakeng sa ho seha tšepe e entsoeng ka tšepe, litšepe tse se nang ferrous, polasetiki, likhoele tsa lik'hemik'hale, graphite, khalase, lejoe le tse tloaelehileng. tšepe, 'me e ka boela ea sebelisoa ho seha tšepe e sa keneleng mocheso, tšepe e sa hloekang, tšepe e phahameng ea manganese, tšepe ea sesebelisoa le lisebelisoa tse ling tse thata tse silang (bololo, k'habote ea ho omisa, Z-mixer, granulator---), ho hatella (ka lehlakore khatello ea hydraulic press kapa extruder), --- sintering (sebopi se pholileng, sebōpi se kopantsoeng kapa sebōpi sa khatello e tlaase ea HIP).
Lisebelisoa tse tala ke ho sila ho metsi, ho omisa, doping ea sekhomaretsi, ebe ho omisoa le ho fokotsa khatello ea kelello ka mor'a ho bōptjoa kapa extrusion, 'me qetellong ho etsa motsoako oa ho qetela o se nang letho ka ho koala le ho sintering.
Bobebe ba tlhahiso ea "round bar extrusion" ke hore potoloho ea tlhahiso e telele.Ho pepeta mekoallo e nyane ea bophara bo ka tlase ho 3mm le ho pshatla lipheletsong tse peli ho tla senya palo e itseng ea thepa.Ha bolelele ba carbide e nyane e bophara ba bar e pota-potile, e mpefatsa ho otloloha ha sekheo.Ha e le hantle, mathata a ho otloloha le a chitja a ka ntlafatsoa ka ho sila ka cylindrical hamorao.
E 'ngoe ke compression molding, e leng tsela eo short bar stock e hlahisoang ka eona.Joalo ka ha lebitso le fana ka maikutlo, ke hlobo e hatellang phofo e entsoeng ka samente ea carbide hore e be sebopeho.Molemo oa mokhoa ona oa ho etsa li-bar carbide ke hore o ka thehoa ka tsela e le 'ngoe' me o fokotsa sekhechana.Nolofatsa mokhoa oa ho itšeha ka terata le ho felisa potoloho ea lintho tse omeletseng tsa mokhoa oa extrusion.Nako e khutsufalitsoeng ka holimo e ka boloka bareki matsatsi a 7-10.
Ha e le hantle, khatello ea isostatic le eona ke ea compression molding.Isostatic pressing ke mokhoa o nepahetseng oa ho etsa mokhoa oa ho hlahisa mekoallo e meholo le e telele ea tungsten carbide.Ka litiiso tsa piston tse ka holimo le tse ka tlaase, pompo ea khatello e kenya motsoako oa metsi pakeng tsa silinda e phahameng ea khatello le rabara e hatelitsoeng, 'me khatello e fetisoa ka rabara e hatelitsoeng ho etsa phofo e entsoeng ka samente ea carbide e hatelletsoeng ho theha.
