Otu esi agbaze ọla kọpa aluminom

Nkealuminum brasusoro dị mgbagwoju anya karị, ụfọdụ n'ime ọla aluminom dị mgbagwoju anya nwere ihe nke atọ na nke anọ dịka manganese, nickel, silicon, cobalt na arsenic.Hal66-6-3-2 na HAL61-4-3-1, bụ ndị nwere ihe ndị ọzọ na-eme ka alloy, bụ alloys nke nwere ihe isii mejupụtara, ụfọdụ n'ime ha bụ ọla kọpa aluminom arụpụtara siri ike sitere na alloys nkedo pụrụ iche.Alloys dị iche iche na-enwekarị ihe mgbaze dị iche iche, ya mere ọ chọrọ usoro mgbaze dị iche iche.
Nke mbụ, ọla kọpa aluminom dị mfe "ụfụfụ" n'oge usoro ịgbaze ma na-emerụ ya ngwa ngwa site na aluminom ma ọ bụ ihe mgbakwunye metal oxide ndị ọzọ.Usoro mgbaze kwesịrị ekwesị kwesịrị ịgụnye ụfọdụ ihe mgbochi.Ọ bụrụ na e nwere ihe nkiri oxide nke aluminom n'elu nke gbazee, ọ nwere ike ichebe mgbaze ruo n'ókè ụfọdụ, ọ dịghịkwa mkpa ịgbakwunye onye na-ekpuchi ihe n'oge agbaze.
Nyocha usoro: Mgbe ị na-agbakwunye zinc na ọdọ mmiri a wụrụ awụ nke ihe nkiri Al2O3 na-echebe, enwere ike ibelata mfu nke zinc.N'ezie, ebe ọ bụ na isi nke zinc nwere ike imebi ihe nkiri oxide, ọ bụ naanị mgbe a na-eji ụda kwesịrị ekwesị eme ihe, ya bụ, mgbaze ahụ nwere ike ichekwa nke ọma karị, enwere ike izere ma ọ bụ belata ọkụ na-ere ọkụ nke zinc.Cryolite abụrụla ihe dị mkpa na ihe dị mkpa na ntugharị eji agbaze ọla aluminom.Aluminom-brass gbazee agaghị ekpo oke ọkụ ka ọ ghara igbochi agbaze ahụ site na oxidizing na ikuru ume.Ọ bụrụ na ọdịnaya gas dị na gbazee dị oke elu, ị nwere ike ịhọrọ mkpuchi flux maka nchacha, ma ọ bụ jiri nchacha gas inert, gụnyere re-fluxing na ikwugharị refining tupu ịwụsa, na iji mgbịrịgba mgbịrịgba na-pịa chloride nnu n'ime gbazee maka agbaze refining. Ụzọ ahụ.Ekwesịrị ịgbakwunye ihe ndị na-agbaze elu dị elu dị ka ígwè, manganese, silicon, wdg dị na brass aluminom dị mgbagwoju anya n'ụdị Cu-Fe, Cu-Mn na ihe ndị ọzọ dị n'etiti.
N'ozuzu, a ga-etinye nnukwu ego na ọla kọpa n'ọkụ na mbụ ma gbazee, enwere ike ịgbakwunye ụgwọ nke kewara nke ọma na agbaze, na zinc na-agbakwunye ikpeazụ na njedebe nke ịgbaze.Mgbe a na-eji ọla dị ọcha mee ihe dị ka ụgwọ, a ga-ehichapụ ha na phosphorus mgbe agbazechara ha, manganese (Cu-Mn), ígwè (Cu-Fe), mgbe ahụ aluminom, na n'ikpeazụ zinc.Na mgbagwoju aluminum brass HAL66-6-3-2, a ga-achịkwa ọdịnaya nke ígwè na 2% ~ 3%, na manganese ọdịnaya kwesịrị ịchịkwa ihe dịka 3%.Ma ọ bụghị ya, mgbe ọdịnaya ha dị elu, ụfọdụ ihe onwunwe nke alloy nwere ike imetụta na-adịghị mma.N'ihi obere njupụta nke aluminom, ọ bụrụ na agbazeghị agbaze nke ọma, ọ nwere ike ime ka ihe mejupụtara kemịkalụ na-enweghị isi.Mgbe enwere mgbaze mgbanwe n'ime ọkụ ahụ, aluminom n'ozuzu na akụkụ nke ọla kọpa nwere ike ibu ụzọ tinye ya, wee tinye zinc mgbe agbazechara ha.Mgbe a na-agbakwunye aluminom, enwere ike ịhapụ oke ọkụ n'ihi ngwakọta nke ọla kọpa na aluminom.Enwere ike iji usoro exothermic mee ka usoro mgbaze ahụ dịkwuo ngwa ngwa, ma ọ bụrụ na arụghị ọrụ ahụ nke ọma, mmeghachi omume exothermic siri ike nwere ike ime ka okpomọkụ dị n'ógbè nke ọdọ mmiri a wụrụ awụ dị elu, na-akpata nhụsianya ike nke zinc, na n'ụzọ siri ike. ikpe, enwere ike ịchụpụ ọkụ n'ọkụ.Okpomọkụ nke mgbaze HAL67-2.5 na-abụkarị 1000 ~ 1100 ℃, na okpomọkụ nke smelting HAL60-1-1, HAL59-3-2, HAL66-6-6-2 na-abụkarị 1080 ~ 1120 ℃, na ala okpomọkụ kwesịrị. a ga-eji dị ka o kwere mee.Okpomọkụ na-agbaze.
