Ọdịiche dị n'etiti Tungsten Carbide na HSS Cutting Tools

Na mgbakwunye na ihe tungsten carbide, a pụkwara imepụta ihe ndị na-egbutu ihe na-eji ígwè dị elu mee ihe. Otú ọ dị, n'ihi nhazi kemịkalụ dị iche iche na ụzọ mmepụta nke tungsten carbide na ígwè dị elu, àgwà nke ihe eji egbutu ihe a kwadebere dịkwa iche.

1. Chemical Njirimara

Igwe ọkụ dị elu, nke a makwaara dị ka ígwè ọrụ dị elu ma ọ bụ nchara n'ihu, bụ nke a na-akpọ HSS, ihe ndị bụ isi kemịkal bụ carbon, silicon, manganese, phosphorus, sulfur, chromium, molybdenum, nickel, na tungsten. Uru nke ịgbakwunye tungsten na chromium na nchara n'ihu bụ ịkwalite nguzogide dị nro nke ngwaahịa ahụ mgbe ọ na-ekpo ọkụ, si otú ahụ na-abawanye ọsọ ọsọ ya.

Tungsten carbide, nke a makwaara dị ka carbide cimented, bụ ihe alloy dabere na ogige mgbakwụnye mgbakwụnye metal na metal dị ka ihe nkedo. Ogige ndị siri ike ndị a na-ahụkarị bụ tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, tantalum carbide, wdg, na ihe ndị na-ejikọkarị bụ cobalt, nickel, iron, titanium, wdg.

2. Njirimara anụ ahụ

The flexural ike nke izugbe-ebumnobi elu-agba ígwè bụ 3.0-3.4 GPa, mmetụta siri ike bụ 0.18-0.32 MJ / m2, na ike bụ 62-65 HRC (mgbe okpomọkụ na-ebili na 600 ° C na ike ga-adị. 48.5 HRC). Enwere ike ịhụ na nchara na-agba ọsọ nwere njirimara nke ike dị mma, nkwụsị nke ọma, nkwụsị ọkụ na-ekpo ọkụ, na thermoplasticity na-adịghị mma.

Ike mkpakọ nke tungsten carbide a na-ejikarị bụ 6000 MPa na ike bụ 69 ~ 81 HRC. Mgbe okpomọkụ na-ebili na 900 ~ 1000 ℃, ike ka nwere ike ịnọgide na-enwe na banyere 60 HRC. Tụkwasị na nke ahụ, ọ nwere ike dị mma, ike siri ike, nkwụsị na-eyi, nkwụsị ọkụ, na nkwụsị nke corrosion. Agbanyeghị, ihe ngosipụta arụmọrụ akọwapụtara nke carbide cimented nwere njikọ chiri anya na akụrụngwa kemịkalụ ya na oke akụrụngwa.

3. Usoro mmepụta

Usoro mmepụta nke ígwè dị elu na-adịkarị: ọkụ ọkụ na-agbaze ugboro ugboro, nchacha ọkụ na-apụ apụ, ikuku degassing, electro slag remelting, ngwa ngwa ngwa igwe, hama, nkenke igwe blanking, ọkụ na-atụgharị n'ime ngwaahịa, efere efere, na ịbịaru. n'ime ngwaahịa.

Usoro mmepụta nke tungsten carbide bụ n'ozuzu: ngwakọta, igwe nri mmiri, ihicha, ịpị, na sintering.

4. Eji

A na-eji ígwè dị elu eme ihe n'ịkpụpụta ngwá ọrụ ịkpụchasị ihe (dị ka ọkpọkọ, mgbata, na agụba) na ngwá ọrụ ziri ezi (dị ka hobs, ndị na-akpụzi ihe, na broaches).

Ewezuga ngwaọrụ ịcha ihe nke tungsten carbide na-ejikwa arụ ọrụ ngwuputa, nha, ịkpụzi, eyi na-eguzogide ọgwụ, oke okpomọkụ, wdg.

Ọtụtụ n'ime otu ọnọdụ ahụ, mbelata ngwa ngwa nke tungsten carbide ngwá ọrụ dị 4 ruo 7 ugboro dị elu karịa nke ígwè dị elu, na ndụ dị elu 5 ruo 80 ugboro.

Ọ bụrụ na ị nwere mmasị na ngwaahịa tungsten carbide ma chọọ ozi ndị ọzọ na nkọwa, ị nwere ike ịkpọtụrụ anyị site na ekwentị ma ọ bụ mail n'aka ekpe, ma ọ bụ zipu ozi US na ala nke ibe.
