Mawonekedwe Ogwiritsa Ntchito Ndodo Za Cemented Carbide Composite

Ndodo zokhala ndi simenti za carbide, zomwe nthawi zambiri zimatchedwa "ndodo zokhala ndi simenti ya carbide," zimayimira uinjiniya wapamwamba kwambiri, wopangidwa kuti ukhale wopambana m'mafakitale ovuta kwambiri. Ndodozi zimamangidwa mwaluso pophatikiza maupangiri olimba kwambiri a carbide, omwe amapangidwa kuchokera ku tungsten carbide granules kapena zoyika zosamva kuvala, zokhala ndi matrix olimba a faifi tambala/siliva (kapena mkuwa) aloyi. Kapangidwe kaphatikizidwe kapadera kameneka kamagwirizana ndi kuuma kwapamwamba komanso kulimba kwa carbide ndi kulimba kwapadera, kukana kukhudzidwa, komanso kutenthetsa kwachitsulo chomangira. Chotsatira chake ndi chinthu chomwe chimaposa zida zachitsulo wamba muzinthu zambiri zovuta. Zomwe zimagwiritsidwa ntchito pazigawo zolimbazi zimapezeka m'mafakitale omwe kukhumudwa kwambiri ndi zovuta zimakhala zovuta tsiku ndi tsiku.

1. Kubowola Mafuta ndi Gasi: Kugonjetsa Pansi Pansi Pansi

M'gawo lamafuta ndi gasi, kubowola bwino komanso moyo wautali wa zida ndizofunikira kwambiri. Ndodo zokhala ndi simenti za carbide ndizofunikira kwambiri pobowola, makamaka muzitsulo zodzigudubuza ndi ma PDC (Polycrystalline Diamond Compact) pang'ono. Nsonga za tungsten carbide zomwe zimayikidwa pamwamba pa ndodo zimakhala ngati malo oyamba okhudzana ndi mapangidwe a miyala. Amaphwanya ndi kupera kudzera mumchenga wonyezimira, shale wolimba, ndi mapangidwe ena achilengedwe. Fayilo ya nickel/copper alloy binder imatsimikizira kuti ndodoyo imatha kupirira kugwedezeka kwakukulu komanso nthawi yopindika yomwe imakumana pakubowola popanda kusweka. Kuphatikizika kumeneku kumakulitsa kwambiri moyo wautumiki wa pobowola, kumachepetsa nthawi yosinthira pang'ono, ndikuwonjezera kuchuluka kwa malowedwe, zomwe zimapangitsa kuti pakhale ndalama zambiri pakubowola.

2. Kukonza Migodi ndi Mchere: Mtima Wochotsa ndi Kuchepetsa Kukula

Makampani opanga migodi ndi omwe amagula kwambiri ndodo zokhala ndi simenti ya carbide. Ndiwofunika kwambiri pazida zambiri zomwe zimagwiritsidwa ntchito pophwanya, kupera, ndi kufukula.

• Makina Ophwanyidwa ndi Kupera:Nyundo ndi mapini mu makina ophwanyira ndi nyundo nthawi zonse zimakhala zopweteka kwambiri chifukwa chokonza miyala ndi miyala. Kuyika zigawozi ndi ndodo zamagulu a carbide kumawonjezera kwambiri moyo wawo wovala, kusunga magwiridwe antchito ndikuchepetsa pafupipafupi kukonza.

• Zida Zokonzekera Misewu ndi Kudutsira:Mano ndi zitoliro pa okonza misewu, oyendetsa migodi, ndi ma trenchers amadalira kapangidwe ka carbide kuti athyole phula lolimba, konkriti, ndi miyala. Nsonga zakuthwa, zolimba za carbide zimapereka ntchito yodula, pomwe thupi lolimba la ndodo limatenga kugwedezeka kulikonse.

• Digger ndi Dredger Components:Pobowola mchenga, miyala, kapena mchere, mitu yodulira ndi milomo ya ndowa imakhala ndi ndodozi kuti athe kukana ma abrasion osasunthika kuchokera ku zosakaniza za slurry, kuwonetsetsa kuti zikugwira ntchito mosalekeza m'malo ovuta.

3. Kumanga ndi Tunneling: Kumanga ndi Kutopetsa ndi Kulondola ndi Kukhalitsa

Pantchito zazikulu zomanga ndi kukonza makina, makina ayenera kukhala amphamvu kwambiri. Nsonga za simenti za carbide ndizofunikira pa:

• Makina Oboola Tunnel (TBMs):Mitu yodula ya ma TBM imakhala ndi zodulira ma disc ndi ma pick omwe nthawi zambiri amalimbikitsidwa kapena opangidwa kwathunthu kuchokera kumagulu a carbide. Ndiwofunikira pakutopetsa mwala ndi nthaka yosakanizika, zomwe zimapatsa kukana kofunikira kuti amalize machulukidwe aatali popanda chodulira chokhazikika.

• Kuyendetsa ndi Kuboola Mulu:Zida zomwe zimagwiritsidwa ntchito pobowola maziko ndikuwunjika m'nthaka yamwala zimapindula ndikuphatikiza ndodozi. Amateteza zida zotsogola kuti zisamavale mwachangu, kuonetsetsa kulondola kwapang'onopang'ono komanso kukhulupirika kwamapangidwe a mabowo obowola.

4. Wear Magawo mu Makina Olemera ndi Kupanga

Kuphatikiza pa mafakitale oyambilira omwe atchulidwa, ndodo zophatikizika izi zimapeza ntchito zapadera ngati zida zovala pazochitika zosiyanasiyana zolemetsa. Amagwiritsidwa ntchito ngati akalozera, zomangira, ndi zomangira zomangira pazida zowononga, monga makina ophulitsira kuwombera, makina ogwirira mchenga, ndi makina aulimi monga zopaka feteleza ndi zida zolima nthaka. Kukhoza kwawo kukana kumanga zinthu ndi kusunga malo osalala kumayamikiridwa kwambiri.

Pomaliza, ndodo zokhala ndi simenti za carbide sizongokhala zakuthupi koma njira yofunikira yaukadaulo. Pogwiritsa ntchito synergistically kuphatikiza katundu wa tungsten carbide ndi ductile metal binder, amapereka kuphatikiza kosagonja kwa kuuma ndi kulimba. Mawonekedwe awo ogwiritsira ntchito amakhazikika pamikhalidwe yomwe mtengo wanthawi yopumira ndikusintha gawo chifukwa cha kuvala ndipamwamba. Zophatikizika izi ndizofunikira pakupititsa patsogolo kupita patsogolo, kukulitsa zokolola, ndikuwonetsetsa kudalirika kwa mafakitale olemera padziko lonse lapansi.
