Ho Tla Nka Nako E Kae Ho Hlahisa Lithupa Tsa Carbide?

Joaloka moetsi oa lithupa tsa tungsten carbide, re lula re fumana lipotso tse 'maloa tse kang, "ke hobane'ng ha ho nka nako e telele ho hlahisa lithupa tsa carbide?". Sengoliloeng sena ke ho u fa karabo, 'me re tla nka mehlala ea ho hlahisa litšepe tse chitja tsa 200kg carbide.

Mokhoa oa ho hlahisa lithupa tsa tungsten carbide

A. Lokisetsa thepa e tala

Hangata, lefapha la ho reka le tla reka le ho boloka phofo ea boleng bo holimo ea tungsten carbide le phofo ea binder.

B. Ho kopanya le ho sila ka metsi: Lihora tse 48

Tungsten carbide powder le binder powder li tla tsoakoa ebe li siloa ka metsi le ethanol mochining oa ho sila bolo. Ho li sila ka mokhoa o lekaneng le ho fihlela boholo bo loketseng ba lijo-thollo, mochini oa ho sila ka bolo o tla lula o sila matsatsi a ka bang 2.

C. Hasa ho omisa: Lihora tse 24

Ka mor'a ho sila ka metsi, tungsten carbide powder slurry Dryska tora e ommeng ea spray ka lihora tse 24. Ke feela ha ho omisa ka spray ho etsa mouoane oa metsi a tungsten carbide powder moo ho hatella le ho sintering ho ka phethoa hamolemo.

D. Ho kopanya: extrusion lihora tse 228; mokotla o omileng oa isostatic Lihora tse 36 (ho kenyelletsa ho lokolla khatello ea ka hare le ho omisa)

Mekhoa e 'meli e meholo eaho bopali-extrusion le mokotla o omileng oa isostatic. Mekhoa ena e 'meli e tla bitsa linako tse fapaneng. Extrusion e tla bitsa lihora tse 12 ho kopanya, 'me mochini o omileng oa isostatic o tla bitsa lihora tse 8. Nakong ea ho hatella, moemeli oa ho etsa o eketsoa nakong ea extrusion, ha mochine o omileng oa isostatic ha o hloke moemeli oa ho etsa.

Ka mor'a ho hatella, lithupa tse kopantsoeng li hloka ho lokolla khatello ea ka hare tlas'a mocheso o sa khaotseng le tikoloho ea mongobo. Ts'ebetso ena e ka qoba mapetsong ts'ebetsong e latelang. Lithupa tse kopaneng tsa Tungsten carbide li tla qeta nako e telele li lokolla khatello ea maikutlo ka hare, lihora tse 144 bakeng sa extrusion, le lihora tse 24 bakeng sa mochini o omileng oa isostatic. Ebe lithupa tse kopantsoeng tsa tungsten carbide, ka mor'a extrusion, li tla kenngoa ka ontong ea ho omisa ka lihora tse 73, 'me lithupa ka mor'a hore mokotla o omileng o hatelle isostatic bakeng sa lihora tse 4 feela.

Le hoja mochine o omileng oa isostatic o tla bitsa nako e fokolang ho feta extrusion, o ka sebetsa feela ho etsa lithupa tse kholo tse nang le bophara bo fetang 16mm.

E. Sintering: Lihora tse 24

Lithupa tse kopantsoeng tsa Tungsten carbide li tla chesoa ka sebōping sa vacuum. Ts'ebetso ena e tla nka lihora tse ka bang 24. Kamora ho sila, likheo tsa molamu oa tungsten carbide li hloka ho sila le ho hlahlojoa.

Ho akaretsa, ts'ebetso ea mantlha ea ho hlahisa likheo tsa 200kg tsa tungsten carbide rod li tla bitsa lihora tse 324 (matsatsi a 13.5) bakeng sa extrusion le lihora tse ka bang 132 (matsatsi a 5.5) bakeng sa ho hatisa mokotla oa isostatic, re sa bue ka nako e sebelisoang ho sila le joalo-joalo.

Leha ho le joalo, ka thepa e lekaneng, ha ua lokela ho tšoenyeha ka nako ea ho fana. Re ka e romella ka matsatsi a 3. 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.
