Usoro mmepụta na nhazi usoro nke mkpanaka Carbide cimented

Ogwe carbide e ji ciment emechara bụ mkpanaka gburugburu carbide ejiri ciment. Carbide cimented bụ ihe mejupụtara ihe mejupụtara igwe na-agbagharị agbagharị (usoro siri ike) yana metal bonding (usoro njikọ) nke ntụ ntụ mebere.

Enwere ụzọ abụọ akpụ maka mkpara gburugburu carbide cimented. Otu ụzọ bụ extrusion akpụ, nke bụ ụzọ kwesịrị ekwesị iji mepụta mkpanaka ogologo ogologo. Ụdị mkpanaka carbide cemented a nwere ike ịbelata ogologo oge ọ bụla onye ọrụ chọrọ n'oge usoro extrusion. Otú ọ dị, n'ozuzu ogologo enweghị ike gafere 350mm. Nke ọzọ bụ mkpakọ ịkpụzi, nke bụ a ụzọ kwesịrị ekwesị maka obere mmanya mmepụta. Dị ka aha ahụ pụtara, a na-agbanye ntụ ntụ carbide simented n'ime ihe.

Alloy ihe na-mere nke refractory metal na a bonding metal site a uzuzu metallurgy usoro. Carbide cimented nwere usoro ihe mara mma dị ka ike siri ike dị elu, nkwụsi ike na-eyi, ike dị mma na ike siri ike, nguzogide okpomọkụ, na nguzogide corrosion. karịsịa elu ya siri ike na iyi nguzogide, nke na-anọgide na-agbanweghị ọbụna na okpomọkụ nke 500 Celsius C, ma ka nwere nnukwu ike na 1000 Celsius.

Mwepu nke gburugburu mmanya extrusion mmepụta bụ na mmepụta okirikiri dị ogologo. Mwepu nke obere ogwe okirikiri dị n'okpuru 3mm, bepụ nsọtụ abụọ ahụ ga-efunahụ ụfọdụ ihe. Ogologo ogologo nke obere dayameta gburugburu mmanya nke cemented carbide, na-akawanye njọ nke kwụ ọtọ nke oghere. N'ezie, enwere ike imezi nsogbu nke nzizi na okirikiri site na ichigharị cylindrical na ogbo ikpeazụ.

Nke ọzọ bụ mkpakọ ịkpụzi, nke a na-eji na-emepụta obere Ogwe. Dị ka aha ahụ pụtara, e nwere ihe na-akpụ akpụ nke na-akụ ntụ ntụ carbide simenti.
