Ts'ebetso ea tlhahiso le ts'ebetso ea ho theha Cemented carbide rod

Li-carbide tse entsoeng ka samente ke lithupa tse chitja tse entsoeng ka samente. Carbide e entsoeng ka samente ke motsoako o entsoeng ka motsoako oa tšepe oa refractory (mohato o thata) le tšepe e kopanyang (mohato oa bonding) o hlahisoang ke phofo ea metallurgy.

Ho na le mekhoa e 'meli ea ho etsa lithupa tse chitja tsa carbide. Mokhoa o mong ke oa ho etsa li-extrusion, e leng mokhoa o loketseng oa ho hlahisa lithupa tse telele tse chitja. Mofuta ona oa lithupa tsa carbide tse entsoeng ka samente li ka khaoloa bolelele bofe kapa bofe boo mosebelisi a bo batlang 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 bakeng sa tlhahiso e khutšoanyane ea bar. Joalokaha lebitso le bolela, phofo e entsoeng ka samente ea carbide e hatelloa hore e be hlobo.

Lisebelisoa tsa alloy li entsoe ka tšepe ea refractory le tšepe e kopanyang ka mokhoa oa metallurgy oa phofo. Carbide e entsoeng ka samente e na le letoto la lintho tse ntle tse kang ho thatafala ho phahameng, ho hanyetsa ho roala, matla a matle le ho tiea, ho hanyetsa mocheso le 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 e-na le boima bo phahameng ho 1000 °C. Carbide e sebelisoa haholo e le lisebelisoa tsa lisebelisoa, tse kang ho fetola lisebelisoa, li-milling cutters, lipolane, li-drill, lithulusi tse boring, joalo-joalo bakeng sa ho itšeha tšepe, litšepe tse se nang ferrous, polasetiki, likhoele tsa lik'hemik'hale, graphite, khalase, lejoe le tšepe e tloaelehileng, hape e ka sebelisoa bakeng sa ho seha ho sila ka metsi ka thepa e thata-thata ho sebetsa joalo ka tšepe e sa keneleng mocheso, tšepe e sa jeleng paate, tšepe e phahameng ea manganese, tšepe ea lisebelisoa (boloala, khabinete ea ho omisa, motsoako oa mofuta oa Z, granulator) --- ho hatella (e nang le mochini o hatisang ka lehlakoreng la hydraulic kapa extruder) -- - Sintering (sebopi sa ho futhumatsa, sebōpi se kopaneng kapa sebōpi sa khatello e tlase ea HIP)

Lisebelisoa tse tala li entsoe ka metsi, li omisitsoe, li kopantsoe le sekhomaretsi ka mor'a ho lekanngoa, ebe li omisitsoe le ho fokotsa khatello ea kelello ka mor'a ho bōptjoa kapa ho ntšoa, 'me motsoako oa ho qetela o se nang letho o thehoa ka ho senya le ho sintering.

Bobebe ba tlhahiso ea "round bar extrusion" ke hore potoloho ea tlhahiso e telele. Katoloso ea mekoallo e chitja e nang le bophara bo nyane ka tlase ho 3mm, ho khaola mahlakore ka bobeli ho tla senya thepa e itseng. Ha bolelele ba bar e chitja e nang le bophara bo bonyenyane ba carbide e entsoeng ka samente, e mpe le ho feta ho otloloha ha sekheo. Ha e le hantle, mathata a ho otloloha le ho pota-pota a ka ntlafatsoa ka ho sila ka cylindrical nakong ea morao-rao.

E 'ngoe ke compression molding, e sebelisetsoang ho hlahisa litšepe tse khutšoanyane. Joalokaha lebitso le bolela, ho na le hlobo e hatellang phofo e entsoeng ka samente ea carbide. Molemo oa mokhoa ona oa ho etsa li-carbide bar: e ka thehoa ka nako e le 'ngoe' me ea fokotsa litšila. Nolofatsa mokhoa oa ho itšeha ka terata 'me u boloke potoloho ea lintho tse omeletseng tsa mokhoa oa extrusion. Nako e khutsufalitsoeng ka holimo e ka boloka matsatsi a 7-10 bakeng sa bareki.

Ha e le hantle, ho hatella isostatic le hona ke ho bōpa. Isostatic pressing ke mokhoa o nepahetseng ka ho fetisisa oa ho etsa li-bar tsa carbide tse kholo le tse telele. Ka ho tiisoa ha lipiston tse ka holimo le tse ka tlaase, pompo ea khatello e kenya mokelikeli pakeng tsa silinda e phahameng ea khatello le rabara e hatelitsoeng, 'me khatello e fetisoa ka rabara e hatelitsoeng ho etsa hore sekontiri se entsoeng ka carbide se bōpehe.

Haeba u thahasella lihlahisoa tsa tungsten carbide 'me u batla boitsebiso bo eketsehileng le lintlha tse ling, u ka RE THUTA ka mohala kapa ka poso ka ho le letšehali, kapa U RE THUSE MAIL botlaaseng ba leqephe.
