Melemo ea Tungsten Carbide ho Tooling ke efe?

Joalo ka ha bohle re tseba, thepa ea tungsten carbide e bitsoa "meno a liindasteri". E na le boima bo phahameng haholo le boima bo phahameng, bo sebelisoang haholo masimong a ho itšeha, ho cheka le ho thibela ho apara.

Wikipedia e hlalosa tungsten carbide ka tsela ena: “Tungsten carbide (molemo oa lik’hemik’hale: WC) ke motsoako oa lik’hemik’hale (ka ho khetheha, carbide) o nang le likarolo tse lekanang tsa tungsten le liathomo tsa carbon. Ka sebopeho sa eona sa mantlha, tungsten carbide ke phofo e ntle e boputsoa, ​​​​empa e ka hatelloa le ho etsoa libopeho ka sintering bakeng sa ho sebelisoa mecheng ea indasteri, lisebelisoa tsa ho seha, li-abrasives, likhetla tse phunyang lihlomo le mabenyane. Tungsten carbide e batla e le thata habeli ho feta tšepe, e nang le modulus ea Young ea hoo e ka bang 530-700 GPa, 'me e imena habeli ho feta tšepe—hoo e batlang e le bohareng pakeng tsa loto le khauta. E ka bapisoa le corundum (α-Al2O3) ka thata-thata 'me e ka belisoa le ho phethoa feela ka li-abrasives tse thata ka ho fetisisa tse kang cubic boron nitride le phofo ea daemane, mabili le metsoako."

Lisebelisoa tsa tungsten carbide li na le ts'ebetso e phahameng joalo. Melemo ke efe ha thepa ea tungsten carbide e sebelisoa tšimong ea lisebelisoa?

1. Boima bo phahameng. Ho thatafala ha tungsten carbide ho fapana ho tloha ho 83HRA ho isa ho 94HRA. Ho thatafala ho phahameng ho etsa hore tungsten carbide e koahele nako e telele ho isa ho makhetlo a 100 ho feta tšepe maemong a kenyelletsang ho khoholeha, khoholeho ea mobu le lehlabathe. Ho hanyetsa ha tungsten carbide ho molemo ho feta ha litšepe tsa lisebelisoa tse senyehileng.

2. Ho hanyetsa mocheso le oxidation. Ho hlahisa tungsten carbide, thepa ea carbide e tla chesoa ka sebōping ka mocheso o phahameng oa hoo e ka bang 1400 centigrade. Li-tungsten-base carbides li sebetsa hantle ho fihla ho 1000 ° F libakeng tse nang le oxidizing le 1500 ° F libakeng tse se nang oxidizing.

3. Botsitso ba Dimensional. Tungsten carbide ha e na liphetoho tsa mohato nakong ea ho futhumatsa le ho pholile 'me e boloka botsitso ba eona ka ho sa feleng. Ha ho phekolo ea mocheso e hlokahalang.

4. Surface Finishes. Qetello ea karolo e ts'oetsoeng e tla ba lisenthimithara tse 50 tse nyane. Bokaholimo, cylindrical kapa ho sila ka hare ka lebili la daemane ho tla hlahisa lisenthimithara tse 18 kapa ho feta mme e ka hlahisa ka tlase ho li-inch tse 4 ho isa ho tse 8. Taemane e qhoqhoa le ho honing e ka hlahisa li-inch tse 2 tse nyane mme ka ho belisoa ho tlase joalo ka 1/2 micro inch.

Khamphani ea Zhuzhou Better Tungsten Carbide ke mofani oa litsebi oa tungsten carbide. Mefuta ea tungsten carbide le tungsten carbide die ke e 'ngoe ea tse rekisoang haholo. ZZbetter e ka hlahisa sehlooho se batang sa tungsten carbide se shoang, tungsten carbide hot forging dies, penta ea tungsten carbide ea shoa, 'me sepekere sa tungsten carbide sea shoa. Li-dies tse ka holimo li sebelisoa haholo liindastering tse ngata 'me li nkeloa sebaka ke tšepe e le khetho e holimo bakeng sa tšebeliso ea lisebelisoa. Ka boima bo phahameng, khanyetso e phahameng ea ho roala, matla a holimo a ho khumama, le ts'ebetso e tsitsitseng ka mocheso o phahameng le o tlaase, hona joale ts'ebeliso ea tungsten carbide e pharaletse le ho feta pele. Khamphani ea rona e tla tsoelapele ho fana ka tharollo ea boleng bo holimo ea carbide ho bareki ba rona le bareki bao e ka bang bareki ka tšepo ea hore carbide ea rona e ka ba thusa ho fihlela boleng ba bona!

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 letsohong le letšehali, kapa U RE THUSE MAIL botlaaseng ba leqephe.
