Ọdịiche dị n'etiti Cemented Carbide na Igwe Ọsọ Ọsọ (HSS)

Cemented carbide na elu-ọsọ ígwè na-ahụkarị downstream ngwaahịa nke refractory metal tungsten (W), ma nwere ezi thermodynamic Njirimara, na ike ga-eji mee ka ọnwụ ngwaọrụ, oyi na-arụ ọrụ ebu na-ekpo ọkụ na-arụ ọrụ ebu, wdg Otú ọ dị, n'ihi na ihe dị iche iche ihe mejupụtara nke abụọ, ha dịkwa iche na usoro nke n'ibu Njirimara na ojiji.

1. Echiche
Carbide cimented bụ ihe alloy mejupụtara carbide metal refractory dị ka tungsten carbide (WC) ntụ ntụ na njikọ njikọ dị ka cobalt ntụ ntụ. Aha Bekee bụ Tungsten Carbide/Cmented Carbide. Ya elu-okpomọkụ carbide ọdịnaya dị elu karịa nke elu-ọsọ ígwè elu nke.

Igwe na-agba ọsọ bụ nnukwu carbon carbon alloy dị elu nke nwere nnukwu tungsten, molybdenum, chromium, cobalt, vanadium na ihe ndị ọzọ, nke kachasị nke carbide metal (dị ka tungsten carbide, molybdenum carbide ma ọ bụ vanadium carbide) na ígwè matrix, nke nwere carbon ọdịnaya nke 0.7% -1.65%, ngụkọta ego nke alloying ọcha bụ. 10% -25%, na aha Bekee bụ High Speed ​​Steels (HSS).

2. Arụmọrụ
Ha abụọ nwere njirimara nke siri ike dị elu, ike dị elu, ịdị mma siri ike, ike na-acha uhie uhie, na-eyi nguzogide, okpomọkụ na-eguzogide na arụmọrụ usoro, na àgwà ndị a ga-adị iche n'ihi ọkwa dị iche iche. N'ikwu okwu n'ozuzu, isi ike, isi ike na-acha uhie uhie, nkwụsị na-eyi na nkwụsị okpomọkụ nke carbide cemented dị mma karịa nke ígwè dị elu.

3. Teknụzụ mmepụta
Usoro mmepụta nke carbide cimented tumadi gụnyere usoro ntụ ntụ ntụ, teknụzụ ịkpụzi injection ma ọ bụ usoro obibi akwụkwọ 3D.

Ụzọ mmepụta nke ígwè dị elu na-agụnye nkà na ụzụ nkedo omenala, nkà na ụzụ remelting electroslag, nkà na ụzụ metallurgy ntụ ntụ na nkà na ụzụ ịkpụzi injection.

4. Jiri
Ọ bụ ezie na ha abụọ nwere ike ịme mma, ọrụ na-ekpo ọkụ na-arụ ọrụ na-arụ ọrụ oyi, arụmọrụ ha dị iche. The ọnwụ ọnwụ nke nkịtị carbide ngwaọrụ bụ 4-7 ugboro elu karịa nke nkịtị elu-ọsọ ígwè ngwaọrụ, na ọrụ ndụ bụ 5-80 ugboro ogologo. N'ihe banyere ịkpụzi, ndụ ọrụ nke cemented carbide nwụrụ bụ 20 ruo 150 ugboro dị elu karịa nke ígwè dị elu na-anwụ. Dị ka ihe atụ, ndụ ọrụ nke na-ekpo ọkụ n'isi extrusion anwụ mere nke 3Cr2W8V ígwè bụ 5,000 ugboro. Ojiji nke extrusion na-ekpo ọkụ na-anwụ anwụ nke YG20 cemented carbide Ndụ ọrụ bụ 150,000 ugboro.
