Usoro mmepụta na ịkpụzi usoro nke mkpanaka carbide cimented

Nkemkpanaka carbide cimentedbụ mkpanaka gburugburu carbide cimented, nke a makwaara dị ka mkpanaka tungsten steel, na nkenke, mkpanaka tungsten nchara gburugburu ma ọ bụ mkpanaka onye otu carbide. Carbide cimented bụ ihe mejupụtara ihe mejupụtara igwe refractory (usoro siri ike) yana metal jikọtara ọnụ (usoro njikọ) nke metallurgy na-emepụta. A na-akpọkwa Tungsten carbide dị ka tungsten steel, na-ekwu okwu, bụ aha mpaghara nke dị iche iche.

Enwere ụzọ abụọ a na-akpụ maka mmepụta nke cemented carbide gburugburu mkpara: otu bụ extrusion ịkpụzi, na extrusion ịkpụzi bụ ụzọ kwesịrị ekwesị na-emepụta ogologo mkpara. Enwere ike ịkpụcha ya n'ogologo ọ bụla onye ọrụ chọrọ n'oge usoro extrusion. Otú ọ dị, n'ozuzu ogologo enweghị ike gafere 350mm. Ndị ọzọ na-anwụ anwụ ịkpụzi, nke bụ a ụzọ kwesịrị ekwesị na-emepụta obere mmanya ihe onwunwe. Dị ka aha ahụ na-egosi, a na-agbanye ntụ ntụ carbide n'ụdị ya na ebu. Ogige ndị siri ike na ọla ejikọtara ọnụ nke ọla ndị na-emegharị emegharị na-agbanwe agbanwe na okpomọkụ nke 500 ° C site na usoro ntụ ntụ ntụ, ma ka nwere nnukwu ike na 1000 ° C.

The akụrụngwa na-mmiri n'ala, nke a mịrị amị, gwakọtara na gluu mgbe kenha, wee akpọnwụwo site ebu Ụlọ Nzukọ ma ọ bụ extruded maka nchegbu enyemaka, na n'ikpeazụ guzobere site degreasing na sintering na-etolite ikpeazụ alloy gross dayameta gburugburu mmanya ihe onwunwe. Ịkọkọ ọnụ abụọ ahụ ga-efunahụ ihe ụfọdụ. Ogologo ogologo nke tungsten carbide obere dayameta gburugburu mkpanaka ihe onwunwe, mwepu nke extrusion mmepụta nke gburugburu mkpanaka ihe bụ na mmepụta okirikiri dị ogologo. Extrude 3mm n'okpuru cylindrical egweri iji melite linearity nke ajị mebiri. N'ezie, enwere ike imezi nsogbu nke nkwụ ọtọ na okirikiri site na iji cylindrical egweri na-esote ogbo.

Nke ọzọ bụ ịkpụ akpụ, nke bụ usoro nke mmepụta mkpanaka mkpụmkpụ, dị ka aha ahụ na-egosi, ọkpụkpụ ahụ ga-agbanye ntụ ntụ carbide cimented iji mepụta. Uru nke usoro a na-akpụzi carbide nke cemented: nke ọzọ nwere ike ịkpụzi n'otu oge, nke bụ usoro nke mmepụta obere mmanya. Dị ka aha ahụ na-egosi, ọ na-akpụzi, na-ebelata ihe mkpofu.
