Aluminom extrusion mmepụta na nhazi teknụzụ
1. Njikwa kachasị mma nke ihe ndị mejupụtara
6063-t5 ụlọ profaịlụ aluminom ga-enwerịrị ụfọdụ ihe eji arụ ọrụ. N'okpuru otu ọnọdụ ndị ọzọ, ike mgbatị na ike ịmị mkpụrụ na-abawanye site na mmụba nke ọdịnaya ahụ. Usoro ike nke 6063 ọla edo bụ tumadi Mg2Si phase. Ego ole ka a ga-ewere Mg, Si na Mg2Si? Mg2Si phase nwere mkpụrụ magnesium abụọ na atọmịkọn atọm. Akụkụ atọmịk sitere na magnesium bụ 24.3 l na otu atomịkọns nke silicon bụ 28.09. Ya mere, oke nchịkọta nke magnesium na silicon na ogige Mg2Si bụ 1.73: 1.
Ya mere, dịka nsonaazụ nyocha dị n'elu, ọ bụrụ na njupụta nke magnesium-silicon ọdịnaya karịrị 1.73, magnesium dị na alloy ọ bụghị naanị ga-etolite Mg2Si phase, kamakwa magnesium karịrị; ma ọ bụghị ya, ọ bụrụ na ọnụọgụ ahụ erughị 1.73, ọ na-egosi na sịlịkọn ga-etolite mpaghara Mg2Si ma nwee silicon fọdụrụnụ.
Ngafe magnesium bụ emerụ ahụ n'ibu Njirimara nke alloys.Magnesium n'ozuzu na-achịkwa na ihe 0,5%, Mg2Si ngụkọta akara na 0.79% .Mgbe e nwere njuputa nke 0.01% sịlịkọn, na n'ibu Njirimara b nke alloy bụ banyere 218Mpa, nke nwere karịrị nnọọ arụmọrụ nke mba, na njupụta silicon na-esi na 0.01% gaa 0.13%, b nwere ike ịgbakwunye na 250Mpa, nke bụ 14.6%. Iji mepụta ụfọdụ ego nke Mg2Si, ọnwụ silicon kpatara site na adịghị ọcha dị ka Fe na A ghaghị ịtụle Mn nke mbụ, ya bụ, a ga-emerịrịrịrị ụfọdụ mkpụrụ nke silicon gafere ka magnesium na alloy 6063 kwekọọ na silicon ahụ, a ga-agbasi mbọ ike iji mee Mg: Si <1.73 n'oge ahụ Nchịkọta nke magnesium ọ bụghị nanị na-eme ka mmetụta na-ewusi ike, kamakwa ọ na-eme ka ọnụ ahịa ngwaahịa ahụ dịkwuo elu.
Ya mere, ihe mejupụtara 6063 alloy ka a na - ejikarị: Mg: 0.45% -0.65%; Si: 0.35% -0.50%; Mg: Si = 1.25-1.30; Odighi ọcha Fe <0.10% -0.25%; Mn <0.10%.
2. Na-ebuli usoro mgbakwunye nke ingot homogenization
Na mmepụta nke profaịlụ extruded obodo, nkọwapụta dị elu nke 6063 alloy bụ 560 ± 20 ℃, mkpuchi ahụ bụ 4-6h, usoro jụrụ oyi na-amanye ikuku jụrụ oyi ma ọ bụ mmiri jụrụ oyi.
The homogenization nke alloy nwere ike melite extrusion ọsọ na belata extrusion mgbali site banyere 6% -10% tụnyere ingot enweghị homogenization.The jụrụ ọnụego mgbe homogenization nwere mmetụta dị mkpa na ọdịda omume nke anụ ahụ. jụrụ mgbe mịrị mmiri, Mg2Si nwere ike gbachapụ kpamkpam na matriks ahụ, na njupụta Si ga-abụkwa ihe ngwọta siri ike ma ọ bụ mgbasa nke ezigbo ahụ. ụdị ingot nwere ike ịgbanye ngwa ngwa na ogo ala ma nweta ọmarịcha igwe na ihu igwe.
Na mmepụta nke aluminum extrusion, dochie ndị na-eguzogide ọkụ ọkụ ọkụ na mmanụ ma ọ bụ gas kpo oku ọkụ nwere ike nweta ihe doro anya na-echekwa ike..dị nhọrọ ezi uche dị na ụdị ọkụ, ọkụ na ọnọdụ mgbasa ikuku nwere ike ime ka ọkụ ahụ nweta ụdị edo edo ma kwụsie ike, ma mezuo ya nzube nke ime ka usoro ahụ kwụsie ike ma melite ogo ngwaahịa.
Mgbe ọtụtụ afọ nke ọrụ na mmụba na-aga n'ihu n'ihu, a kpọbatara ụlọ ọkụ na-ere ọkụ na-ere ọkụ na-ere ọkụ karịa 40% na ahịa.Ọkụ ọkụ ọkụ na-agba ọkụ mgbe ọ kpesịrị ngwa ngwa karịa 570 ℃, na mgbe oge nchekwa ọkụ, na-eme ka mmiri na-agbapụta na nso extrusion okpomọkụ extrusion, akwụkwọ na-ekpo ọkụ na-ekpo ọkụ enwetawo usoro homogenization, usoro a na-akpọ ọgwụgwọ iri abụọ, na-ezute ihe 6063 alloy hot extrusion chọrọ, ma si otú a na-azọpụta otu ụdị kemịkalụ, nwere ike ịchekwaa ntinye akụrụngwa na ike ike, bụ usoro a ga-akwalite.
3. Na-ebuli extrusion na usoro ọgwụgwọ ọkụ
3.1 kpo oku nke ingot
Maka mmepụta extrusion, okpomọkụ extrusion bụ isi dị oke mkpa ma dị oke egwu.Ọdụ mgbatị nwere mmetụta dị ukwuu na ogo ngwaahịa, nrụpụta mmepụta, ịnwụ ndụ na oriri ike.
Nsogbu kachasị mkpa nke extrusion bụ njikwa nke okpomọkụ ọla. Site na kpo oku nke ingot na mkpochapu nke profaịlụ extrusion, ọ dị mkpa iji hụ na usoro nke agbaze anaghị ewepụ ihe ngwọta ma ọ bụ gosipụta mgbasa nke obere ahụ.
A na-edozi ọnọdụ okpomọkụ nke 6063 alloy ingot n'ime oke okpomọkụ nke Mg2Si ọdịda, na oge kpo oku nwere mmetụta dị mkpa na ọdịda Mg2Si. N'ikwu okwu n'ozuzu, enwere ike ịtọọ ọkụ 6063 alloy ingot dị ka:
Ezigbo ihe na-adịghị mma: 460-520 ℃; Homogenized ingot: 430-480 ℃.
A na-agbanwe okpomọkụ nke extrusion dịka ngwaahịa dị iche iche na nrụgide unit n'oge ọrụ.The okpomọkụ nke ingot na mpaghara deformation na-agbanwe n'oge usoro extrusion. Na mmecha nke usoro extrusion, ọnọdụ okpomọkụ nke mpaghara nrụrụ na-eji nwayọọ nwayọọ na-agba ọsọ ma na-agbapụ ngwa ngwa. Ya mere, iji gbochie ntoputa nke mgbawa extrusion, a ga-eji nwayọọ nwayọọ belata ngwa ngwa na ọganihu nke usoro extrusion na mmụba nke ọnọdụ nrụrụ mpaghara.
3.2 extrusion ọsọ
A ghaghị iji ọsọ ọsọ na-achịkwa extrusion n'oge usoro extrusion ahụ.Ọsọ ọsọ ọsọ nwere mmetụta dị mkpa na mmetụta ọkụ nke nrụrụ, nrụrụ nrụrụ, nyochaghachi na usoro ngwọta siri ike, akụrụngwa akụrụngwa na njirimara nke ngwaahịa.
Ọ bụrụ na extrusion ọsọ dị oke ọsọ, elu nke ngwaahịa a ga-apụta pitting, mgbape na na. N'otu oge ahụ, oke ngwa ngwa extrusion ọsọ na-abawanye inhomogeneity nke metal deformation.The outflow ọnụego n'oge extrusion na-adabere na ụdị nke alloy na jiometrị, nha na ọnọdụ ihu igwe nke profaịlụ.
Enwere ike ịhọrọ ọsọ ọsọ nke profaịlụ 6063 alloy (ọsọ ọsọ nke ọla) dị ka 20-100 m / min.
Site na ọganihu nke teknụzụ nke oge a, enwere ike ịchịkwa ọsọ nke extrusion site na mmemme ma ọ bụ mmemme echepụtara. Ka ọ dị ugbu a, e mepụtala teknụzụ ọhụụ dịka usoro nke extrusion nke isothermal na CADEX.By na-agbanwezi ngwa ngwa nke extrusion iji mee ka ọnọdụ okpomọkụ nke mpaghara nrụrụ dị na mgbe niile, ebumnuche nke ngwa ngwa ngwa na-enweghị mgbape nwere ike nweta.
Iji meziwanye arụmọrụ mmepụta, enwere ike ịme ọtụtụ ihe na usoro ahụ. Mgbe ị na-eji kpo oku ọkụ ọkụ, enwere gradient okpomọkụ nke 40-60 ℃ (gradient kpo oku) na ntụpọ nke ogologo nke ingot. E nwekwara mmiri jụrụ anwụ extrusion, ya bụ, na azụ na nsọtụ nke ebu mmiri amanye jụrụ, ule gosiri na extrusion ọsọ nwere ike mụbara site 30% -50%.
N'ime afọ ndị na-adịbeghị anya, e jiri nitrogen ma ọ bụ mmiri mmiri nitrogen mee ka ịnwụ anwụ (extrusion die) ná mba ọzọ iji mee ka ọ gbasaa ngwa ngwa, meziwanye ndụ anwụ ma melite ogo profaịlụ profaịlụ. na obi jụrụ ngwaahịa ngwangwa mkpi, obi jụrụ extrusion anwụ na metal deformation ebe, ka deformation okpomọkụ napụrụ, na ebu ụzọ ọpụpụ na-achịkwa ikuku nke nitrogen n'otu oge, belata aluminom oxide, mbenata alumina adhesion na ìgwè, otú ikuku nitrogen iji meziwanye ogo nke ngwaahịa, nwere ike ime ka ngwa ngwa nke extrusion dịkwuo mma.CADEX bụ usoro ọhụụ nke mepụtara ọhụrụ, nke na-etolite usoro mmechi mechiri emechi yana okpomọkụ extrusion, ọsọ extrusion na mgbatị mgbatị n'oge usoro extrusion iji mezuo oke extrusion na mmepụta arụmọrụ ma hụ na arụmọrụ kacha mma.
3.3 quenching na igwe
Ebumnuche nke 6063-t5 quenching bụ iji chekwaa Mg2Si siri ike gbazere na matriki ọla na akwa okpomọkụ mgbe a na-eme ka oghere ihe dị jụụ na ọnọdụ ụlọ ngwa ngwa. Ọnụ ọgụgụ jụrụ oyi na-adịkarị ka ọdịnaya nke oge ahụ na-ewusi ike. ọnụego nke 6063 alloy bụ 38 ℃ / min, n'ihi ya, ọ kwesịrị ekwesị maka ikuku quenching.The ike ike ike gbanwere site na-agbanwe agbanwe na-akwado na onye ofufe mgbanwe, nke mere na okpomọkụ nke ngwaahịa tupu obimgbalielu ịgbatị nwere ike belata 60 ℃.
3.4 erughị ala ịgbatị
Mgbe profaịlụ si na onu onwu, izugbe traction na traktọ.Mgbe traktọ ahụ na-arụ ọrụ, ọ na-eme ka ngwaahịa ndị ahụ na-apụ apụ na-agba ọsọ na ọsọ ọsọ nke ngwaahịa na ụfọdụ esemokwu traction. Ebumnuche iji traktọ bụ iji belata ogologo nke multi-waya extrusion na hichapụ, kamakwa iji gbochie profaịlụ nke ebu oghere mgbe agbagọ, ekwe, obimgbalielu ịgbatị ka nsogbu.
Mgbatị mgbatị nwere ike ọ bụghị naanị iwepụ ọdịdị ogologo nke ngwaahịa a, kamakwa belata nrụgide fọdụrụnụ, melite njirimara ike ya ma jigide ihu ya dị mma.
3.5 ịka nká
Ka nká na-achọ edo okpomọkụ, okpomọkụ dị iche na-agaghị ± 3-5 ℃ .The keakamere ịka nká okpomọkụ nke 6063 alloy bụ n'ozuzu 200 ℃ .The ịka nká mkpuchi oge bụ 1-2 hours.In iji melite n'ibu Njirimara, ịka nká nke 180-190 Maka awa 3-4 ka a na-ejikwa, mana arụmọrụ mmepụta ga-ebelata.
