Yuav Ua Li Cas Ua Cov Carbide Substrate ntawm PDC Cutters

PDC cutters yog dav siv nyob rau hauv mining, roj, thiab roj drilling kev lag luam. Raws li peb paub, cov qauv ntawm PDC cutter muaj ob ntu, ib qho yog txheej pob zeb diamond, thiab lwm qhov yog carbide substrate. PDC cutters ua ke nrog cov pob zeb diamond hauv siab hardness thiab carbide substrate hauv kev cuam tshuam. PDC cutter zoo yuav tsum tsis tsuas yog cov cuab yeej zoo xwb, tab sis kuj yog cov khoom siv zoo tshaj plaws. Carbide substrate plays lub luag haujlwm tseem ceeb hauv nws. Niaj hnub no peb xav qhia seb yuav ua li cas cov carbide substrate tau tsim.

Cemented carbide (tungsten carbide) yog cov khoom siv tawv ua los ntawm cov khoom zoo ntawm carbide cemented rau hauv cov khoom sib xyaw los ntawm cov hlau khi. Cemented Carbides tau txais lawv cov tawv tawv los ntawm tungsten Carbide nplej thiab lawv cov tawv tawv los ntawm kev sib koom ua ke tsim los ntawm cementing kev txiav txim ntawm Cobalt hlau. Los ntawm kev sib txawv ntawm Cobalt, peb tuaj yeem hloov qhov hardness, hnav tsis kam, thiab toughness (shock lossis cuam tshuam tsis kam) ntawm carbide los muab kev ua tau zoo rau koj daim ntawv thov tshwj xeeb. Cov qib carbide rau PDC cutter substrate txawv ntawm YG11 txog YG15.

Cov txheej txheem tseem ceeb ntawm carbide substrate yog raws li hauv qab no:

Formula raws li qib: Ua ntej, WC hmoov, cobalt hmoov, thiab doping ntsiab yuav raug muab sib xyaw raws li tus qauv qauv los ntawm cov khoom muaj paub txog. Piv txwv li, rau peb qib UBT20, nws yuav yog 10.2% Cobalt, thiab qhov sib npaug yog WC hmoov thiab doping ntsiab.

Hmoov ntub milling: Cov hmoov sib xyaw WC, cobalt hmoov thiab doping ntsiab yuav muab tso rau hauv ntub milling tshuab. Lub pob ntub dej milling yuav kav ntev li 16-72 teev raws li kev siv tshuab ntau lawm.

Hmoov ziab: Tom qab milling, cov hmoov yuav muab tshuaj tsuag kom tau cov hmoov qhuav los yog granulate. Yog hais tias txoj kev tsim yog extrusion, cov hmoov sib tov yuav tsum tov dua nrog Adhesive.

Pwm nias: Cov hmoov sib tov no tau muab tso rau hauv pwm thiab nias nrog kev kub siab rau cov duab.

Sintering: Thaum sib tw 1380 ℃, cobalt yuav ntws mus rau hauv qhov chaw dawb ntawm tungsten carbide nplej. Lub sijhawm sintering yog li 24 teev nyob ntawm cov qib sib txawv thiab qhov ntau thiab tsawg.

ZZbetter muaj kev tswj nruj rau cov khoom siv raw ntawm pob zeb diamond grit thiab carbide substrate. Yog li ntawd peb tuaj yeem tsim PDC cutters zoo rau koj.

ZZbetter muaj ntau qhov ntau thiab tsawg ntawm PDC cutters rau koj xaiv. Kev xa khoom sai hauv 5 hnub kom txuag koj lub sijhawm. Cov qauv txiav txim tau txais kev kuaj. Thaum koj xav tau hloov kho koj lub laum me ntsis, ZZbetter tuaj yeem muab koj lub tshuab txiav PDC sai tshaj plaws.

Yog tias koj txaus siab rau cov khoom lag luam tungsten carbide thiab xav paub ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa mus rau US MAIL hauv qab ntawm nplooj ntawv.
