Phapang lipakeng tsa Tungsten Carbide le HSS Cutting Tools

Ntle le lisebelisoa tsa tungsten carbide, lisebelisoa tsa ho itšeha li ka boela tsa hlahisoa ka thepa ea tšepe e phahameng haholo. Leha ho le joalo, ka lebaka la lik'hemik'hale tse fapaneng tsa lik'hemik'hale le mekhoa ea tlhahiso ea tungsten carbide le tšepe e phahameng ea lebelo, boleng ba lisebelisoa tse lokiselitsoeng tsa ho itšeha le tsona li fapane.

1. Lintho tsa lik'hemik'hale

Tšepe ea lebelo le phahameng, eo hape e tsejoang e le tšepe ea sesebelisoa sa lebelo le holimo kapa tšepe e ka pele, hangata e bitsoa HSS, metsoako ea mantlha ea lik'hemik'hale ke k'habone, silicon, manganese, phosphorus, sebabole, chromium, molybdenum, nickel le tungsten. Molemo oa ho eketsa tungsten le chromium ho tšepe e ka pele ke ho matlafatsa khanyetso e bonolo ea sehlahisoa ha se futhumala, kahoo se eketsa lebelo la ho itšeha.

Tungsten carbide, eo hape e tsejoang e le cemented carbide, ke sesebelisoa sa alloy se thehiloeng ho metsoako e rarahaneng ea tšepe le tšepe joalo ka setlamo. Lik'hemik'hale tse thata tse tloaelehileng ke tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, tantalum carbide, joalo-joalo, 'me li-binders tse tloaelehileng ke cobalt, nickel, tšepe, titanium, joalo-joalo.

2. Lintho tsa 'mele

Matla a feto-fetohang a tšepe e phahameng ea lebelo le phahameng ke 3.0-3.4 GPa, matla a ts'usumetso ke 0.18-0.32 MJ / m2, 'me boima ke 62-65 HRC (ha mocheso o nyolohela ho 600 ° C hore boima bo tla ba teng. 48.5 HRC). Ho ka bonoa hore tšepe ea lebelo le phahameng e na le litšobotsi tsa matla a matle, ho hanyetsa ho apara hantle, ho hanyetsa mocheso o mahareng, le thermoplasticity e mpe. Ha e le hantle, lipontšo tse khethehileng tsa ts'ebetso ea tšepe ea lebelo le phahameng li amana haufi-ufi le metsoako ea eona ea lik'hemik'hale le karo-karolelano ea lihlahisoa tse tala.

Matla a hatellang a tungsten carbide e sebelisoang hangata ke 6000 MPa mme boima ke 69 ~ 81 HRC. Ha mocheso o nyolohela ho 900 ~ 1000 ℃, ho thatafala ho ntse ho ka bolokoa hoo e ka bang 60 HRC. Ho phaella moo, e na le matla a matle, ho tiea, ho hanyetsa ho apara, ho hanyetsa mocheso le ho hanyetsa ho bola. Leha ho le joalo, matšoao a tobileng a ts'ebetso ea carbide e entsoeng ka samente e amana haufi-ufi le metsoako ea eona ea lik'hemik'hale le karo-karolelano ea lihlahisoa tse tala.

3. Mokhoa oa tlhahiso

Ts'ebetso ea tlhahiso ea tšepe ea lebelo le phahameng ka kakaretso ke: ho qhibilihisa sebōpi khafetsa, ho hloekisa ka ntle ho sebōpi, ho hloekisa sebōpi, ho qhibilihisa electro slag, mochine o potlakileng oa ho theha, hamore ea forging, ho koala mochine o nepahetseng, ho chesa ho kenya lihlahisoa, likarolo tsa poleiti le ho taka. ho kena lihlahisoa.

Mokhoa oa tlhahiso ea tungsten carbide ka kakaretso ke: ho kopanya, ho sila ka metsi, ho omisa, ho hatella le ho sila.

4. Lisebelisoa

Tšepe ea lebelo le phahameng e sebelisoa haholo ho etsa lisebelisoa tsa ho seha (tse kang liboro, lipompo, le li-blade tsa sakha) le lisebelisoa tse nepahetseng (joalo ka li-hobs, li-gear shapers le li-broaches).

Ntle le lisebelisoa tsa ho itšeha tseo tungsten carbide e sebelisetsoang ho etsa merafo, ho lekanya, ho bōpa, ho se sebetse, mocheso o phahameng, joalo-joalo.

Haholo-holo tlas'a maemo a tšoanang, lebelo la ho itšeha la lithulusi tsa tungsten carbide ke makhetlo a 4 ho isa ho a 7 ho feta a tšepe e phahameng, 'me bophelo bo phahame ka makhetlo a 5 ho isa ho a 80.

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 RE ROMELA MAIL botlaaseng ba leqephe.
