Otu esi emegharị Tungsten Carbide
Tungsten carbide (WC) bụ kemịkalụ ọnụọgụ abụọ nke tungsten na carbon na nha stoichiometric nke 93.87% tungsten na 6.13% carbon. Otú ọ dị, ụlọ ọrụ mmepụta ihe okwu ahụ na-egosikarị tungsten carbide ciment; ngwaahịa metallurgical powdered powdered nke nwere ezigbo ọka nke tungsten carbide dị ọcha jikọtara ọnụ na matriks cobalt. Ogo nke ọka tungsten carbide sitere na ½ ruo 10 microns. Ọdịnaya cobalt nwere ike ịdị iche site na 3 ruo 30%, mana ọ ga-adịkarị site na 5 ruo 14%. Ogo ọka na ọdịnaya cobalt na-ekpebi ngwa ma ọ bụ njedebe nke ngwaahịa emechara.
Carbide cimented bụ otu n'ime ọla kachasị ọnụ ahịa, ngwaahịa tungsten carbide bụ nke a na-eji eme ihe maka ịkpụ na imepụta ngwaọrụ, ihe akpụ, abrasives, ibe nkute, anwụ, mpịakọta, ihe ịchọ mma na iyi ihe mkpuchi. Tungsten carbide na-arụ ọrụ dị mkpa na mmepe ụlọ ọrụ. Anyị niile maara na tungsten bụ ụdị ihe a na-apụghị imeghari. Àgwà ndị a na-eme ka tungsten carbide scrap bụrụ otu n'ime ihe kachasị mma maka ịmegharị ihe.
Kedu ka esi emegharị tungsten na carbide tungsten? Enwere ụzọ atọ na China.
Ka ọ dị ugbu a, a na-enwekarị ụdị atọ nke cemented carbide recycling na regeneration nke a na-ejikarị eme ihe n'ụwa, ọ bụ usoro ịgbaze zinc, usoro mgbasa electro-mkpọsa, na usoro pulverization.
1. Usoro ịgbaze Zinc:
Usoro ịgbaze zinc bụ ịgbakwụnye zinc na okpomọkụ nke 900 Celsius iji mepụta zinc-cobalt alloy n'etiti cobalt na zinc n'ime carbide cemented n'efu. N'otu oge okpomọkụ, a na-ewepụ zinc ahụ site na mpụta ihe na-ekpo ọkụ ka ọ ghọọ ogbo dị ka ihe mgbochi alloy wee gwerie ya, gbachie ma gbanye ya ka ọ bụrụ ntụ ntụ. N'ikpeazụ, a na-akwado ngwaahịa carbide cemented dị ka usoro a na-emekarị. Otú ọ dị, usoro a nwere nnukwu ego ntinye ego, ọnụ ahịa mmepụta dị elu, na ike oriri, ọ na-esikwa ike iwepụ zinc kpamkpam, na-ebute àgwà ngwaahịa na-adịghị akwụ ụgwọ (arụmọrụ). Tụkwasị na nke ahụ, zinc na-ekesa ihe eji eme ihe na-emerụ ahụ mmadụ. Enwekwara nsogbu mmetọ gburugburu ebe obibi na-eji usoro a.
2. Usoro mgbasa:
Usoro mgbasa elektrọnik bụ iji onye na-ahụ maka ịsa mmiri kwesịrị ekwesị gbazee ihe nkedo metal cobalt n'ime ihe mkpofu simented carbide n'ime ihe ngwọta leaching n'okpuru ọrụ eletriki wee hazie ya na kemịkal ka ọ bụrụ ntụ ntụ cobalt, nke a ga-agbaze. A na-ehicha ihe mgbochi alloy nke ihe nkedo.
Mgbe a na-egwepịa ma na-egweri, a na-enweta tungsten carbide ntụ ntụ, na n'ikpeazụ, a na-emepụta ngwaahịa carbide cimented ọhụrụ dị ka usoro omenala si dị. Ọ bụ ezie na usoro a nwere njiri mara mma ntụ ntụ na ọdịnaya adịghị ọcha dị ala, ọ nwere ọghọm nke usoro ogologo usoro, akụrụngwa electrolysis mgbagwoju anya, yana nhazi oke nke tungsten-cobalt n'efu nke cemented carbide nwere ọdịnaya cobalt karịrị 8%.
3. Usoro nzọpịa igwe omenala:
Usoro ịhịa aka n'ahụ nke ọdịnala bụ ngwakọta akwụkwọ ntuziaka na nhịahụ, a na-etinye carbide simenti n'efu nke ejiri aka kụrie ya n'ime mgbidi dị n'ime ya na efere simenti nke nwere mkpuchi carbide na igwe nhịahụ nke nwere nnukwu bọọlụ simenti nwere nnukwu nha. A na-egwepịa ya n'ime ntụ ntụ site na ntụgharị na (na-atụgharị) mmetụta, na mgbe ahụ, mmiri-ala n'ime ngwakọta, na n'ikpeazụ mee ka ngwaahịa carbide cimented dị ka usoro omenala si dị. A kọwara ụdị usoro a n'isiokwu bụ "Mmegharị, Mweghachi, na iji ihe mkpofu Cemented Carbide". Ọ bụ ezie na usoro a nwere uru nke usoro dị mkpirikpi na obere ntinye ego akụrụngwa, ọ dị mfe ịgwakọta ihe ndị ọzọ na-adịghị ọcha n'ime ihe ahụ, na ikuku oxygen nke ihe a gwakọtara dị elu, nke nwere mmetụta siri ike na àgwà nke ngwaahịa alloy, na enweghị ike imezu ihe achọrọ nke ụkpụrụ mmepụta, ọ na-adịkwa mgbe niile Na mgbakwunye, arụmọrụ na-egwepịa ya dị oke ala, ọ na-ewekarị ihe dị ka awa 500 nke mpịakọta ma na-egweri, ọ na-esikarịkwa ike nweta mma dị mkpa. Ya mere, usoro ọgwụgwọ mmeghari emebeghị ka ọha na eze tinye ya n'ọrụ.
