Mokhoa oa ho Hlahisa Substrate ea Carbide ea PDC Cutters

Li-cutters tsa PDC li sebelisoa haholo indastering ea merafo, ea oli le ea khase. Joalokaha re tseba, sebopeho sa sehahi sa PDC se na le likarolo tse peli, e 'ngoe ke lera la daemane,' me e 'ngoe ke substrate ea carbide. Li-cutters tsa PDC li kopanya le daemane ka thata e phahameng le substrate ea carbide ho hanyetsa tšusumetso. PDC cutter ea boleng bo holimo ha e hloke theknoloji e ntle feela, empa le thepa e tala ea premium. Carbide substrate e phetha karolo ea bohlokoa ho eona. Kajeno re rata ho arolelana hore na substrate ea carbide e hlahisitsoe joang.

Carbide e entsoeng ka samente (tungsten carbide) ke thepa e thata e entsoeng ka likaroloana tse ntle tsa carbide tse kentsoeng ka motsoako ka tšepe e kopanyang. Li-Cemented Carbides li fumana ho thatafala ha tsona ho tsoa ho lijo-thollo tsa Tungsten Carbide le ho tiea ha tsona ho tsoa ho maqhama a hlahisoang ke ketso ea ho tiisa ea tšepe ea Cobalt. Ka ho fapanyetsana palo ea Cobalt, re ka fetola ho thatafala, ho hanyetsa ho apara, le ho tiea (ho tsosoa kapa ho hanyetsa tšusumetso) ea carbide ho fana ka tshebetso e nepahetseng bakeng sa kopo ea hau e khethehileng. Boemo ba carbide bakeng sa substrate ea PDC cutter e fapana ho tloha ho YG11 ho ea ho YG15.

Mokhoa o ka sehloohong oa tlhahiso ea carbide substrate ke o latelang:

Foromo mabapi le kereiti: Taba ea pele, phofo ea WC, phofo ea cobalt, le likarolo tsa doping li tla tsoakoa ho latela foromo e tloaelehileng ke Metsoako e nang le boiphihlelo. Ka mohlala, bakeng sa sehlopha sa rona sa UBT20, e tla ba 10.2% Cobalt, 'me tekanyo ke phofo ea WC le likarolo tsa doping.

Ho sila ka phofo e metsi: Phofo e tsoakiloeng ea WC, phofo ea cobalt le likarolo tsa doping li tla kenngoa mochining oa ho sila o metsi. Ho sila ka bolo e metsi ho tla nka lihora tse 16-72 mabapi le mahlale a fapaneng a tlhahiso.

Ho omisa phofo: Kamora ho sila, phofo e tla omisoa ho fumana phofo e omileng kapa granulate. Haeba mokhoa oa ho etsa e le extrusion, phofo e tsoakiloeng e tla kopanngoa hape le Adhesive.

Ho hatella hlobo: Phofo ena ea motsoako e kenngoa ka har'a hlobo ebe e hatelloa ka khatello e phahameng ho sebopeho.

Sintering: Hoo e ka bang 1380 ℃, cobalt e tla phalla libakeng tse sa lefelloeng pakeng tsa lijo-thollo tsa tungsten carbide. Nako ea sintering e ka ba lihora tse 24 ho latela limaraka le boholo bo fapaneng.

ZZbetter e na le taolo e tiileng bakeng sa thepa e tala ea grit ea daemane le substrate ea carbide. Ke ka lebaka leo re ka u hlahisetsang li-cutters tsa boleng bo holimo tsa PDC.

ZZbetter e na le mefuta e fapaneng ea boholo ba li-cutters tsa PDC bakeng sa khetho ea hau. Ho tsamaisoa ka potlako nakong ea matsatsi a 5 ho boloka nako ea hau. Odara ea mohlala e amoheleha bakeng sa tlhahlobo. Ha o hloka ho nchafatsa mochini oa hau oa ho cheka, ZZbetter e ka u fa PDC seha kapele.

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.
