Akụkọ mmepe nke Silicon carbide crucible

N'ihe gbasara metallurgy, akụkọ ihe mere eme nke Silicon carbide crucible nke e ji agbaze ọla ndị na-abụghị igwe nwere ike ị nweta azụ na 1930s. Usoro ya gbagwojuru anya na-agụnye ịchipịa akụrụngwa, batching, ntugharị aka ma ọ bụ ịkpụgharị mpịakọta, ihicha, igba egbe, ịgba mmanụ na ịgbanye mmiri. Ihe eji eme ihe na-agụnye graphite, ụrọ, pyrophyllite clinker ma ọ bụ elu-alumina bauxite clinker, monosilica ntụ ntụ ma ọ bụ ferrosilicon ntụ ntụ na mmiri, gwakọtara n'otu akụkụ. Ka oge na-aga, agbakwunyere silicon carbide iji kwalite conductivity thermal ma melite ogo. Otú ọ dị, usoro ọdịnala a nwere ike oriri dị elu, ogologo usoro mmepụta ihe, na nnukwu mfu na nrụrụ na ogbo ngwaahịa gwụchara.

N'ụzọ dị iche, usoro nhazi crucible kachasị dị ugbu a bụ ịpị isostatic. Teknụzụ a na-eji graphite-silicon carbide crucible, yana resin phenolic, tar ma ọ bụ asphalt dị ka ihe na-ekekọta, yana graphite na silicon carbide dị ka isi akụrụngwa. Ihe na-esi na crucible pụta nwere obere porosity, nnukwu njupụta, udidi edo na nguzogide corrosion siri ike. N'agbanyeghị uru ndị a, usoro ọkụ ọkụ na-ahapụ anwụrụ ọkụ na uzuzu na-emerụ ahụ, na-ebute mmetọ gburugburu ebe obibi.

Evolushọn nke mmepụta nke Silicon carbide crucible na-egosipụta nchụso ụlọ ọrụ na-aga n'ihu nke arụmọrụ, ịdịmma na ọrụ gburugburu ebe obibi. Ka teknụzụ na-aga n'ihu, a na-elekwasị anya n'ịzụlite ụzọ iji belata oriri ume, belata usoro mmepụta ihe na ibelata mmetụta gburugburu ebe obibi. Ndị na-emepụta ihe na-emepụta ihe na-enyocha ihe ọhụrụ na usoro iji nweta ihe mgbaru ọsọ ndị a, na-achọ ime ka nguzozi n'etiti ọdịnala na ọgbara ọhụrụ. Ka ọchịchọ maka mgbaze ígwè na-abụghị nke ígwè na-aga n'ihu na-eto eto, mmepe na mmepụta ihe na-emepụta ihe ga-ekere òkè dị mkpa n'ịkpụzi ọdịnihu nke metallurgy.
