Ibha yeAluminiyam eyi-6061 eyongeziweyo – i-T6 Temper Stock

Ibha yeAluminiyam ejikelezileyo - Ingxelo yoQinisekiso lweNkqubo kunye noMgangatho

Iibhari zethu ezijikelezileyo ze-aluminium zenziwe ngee-ingots ze-aluminium eziphambili ezinobunyulu obuyi-≥99.7%. Indlela epheleleyo yemveliso yile ilandelayo:
1. Ukunyibilikisa nokuCoca: Isithando sokunyibilikisa i-vacuum esidityaniswe ne-in-line degassing kunye ne-ceramic foam filtration ziqinisekisa ukuba umxholo we-hydrogen uhlala ulingana ne-0.12 ml/100g Al, nto leyo ebangela ukuba kungabikho mingxunya kunye nokufakwa kwezinto.
2. Ukuphosa okungapheliyo: Ukuphosa okushushu okuphezulu kwinqanaba elifanayo ngolawulo oluzenzekelayo lwenqanaba lokubumba; umaleko wokwahlulahlula ≤3 mm, ubungakanani bengqolowa Ibanga 1.
3. Ukudibanisa: Ukudibanisa kwe-gradient iiyure ezili-12–18 kususa ukwahlulwahlulwa kwe-dendritic kunye noxinzelelo olushiyekileyo.
4. Ukukhupha: Ii-press ze-oyile-hydraulic ze-6500–12500 T, ukukhupha phambili kunye ne-quench yokuvala amanzi-umoya kwi-intanethi. Ukubeka iliso ngexesha langempela kwisikhongozeli kunye nobushushu bokuphuma kuqinisekisa ukunyamezelana kobukhulu ngaphakathi kwe-±0.15 mm (umgangatho ophezulu, ongcono kuneemfuno ezisemgangathweni).
5. Ukolula kunye nokuguga okwenziwayo: Ukuqiniswa kwerola edibeneyo kunye nokuqiniswa kwe-tensile kufezekisa ukuthe tye ≤0.3 mm/m. Ukuguga kwe-T6/T6511 kwenziwa kwii-oven ezinobushushu obufanayo ±3 °C; umahluko wepropathi yoomatshini phakathi kweebhetshi ≤5 MPa.
6. Ukugqiba: Ukugaya ngaphandle kwesikhungo, ukuxobula, ukusika ngokuchanekileyo. Ububanzi be-φ8–650 mm, ukugqitywa komphezulu we-Ra ≤0.4 μm, ukunyamezela ubude ±0.5 mm.

Inkqubo yoLawulo loMgangatho

● Ukulandelelana kwenani elipheleleyo ukusuka kwinombolo yobushushu be-ingot ukuya kwibha egqityiweyo
● Ukugcinwa kweesampulu zamangqina ≥iminyaka emi-2 ukuze kuvavanywe kwakhona ngumntu wesithathu (SGS, BV, TÜV, njl.njl.)
● Ukuhlolwa kwe-100% yeeparameter ezibalulekileyo: • Ukwakheka kweekhemikhali (i-spectrometer yokufunda ngqo) • Iimpawu zoomatshini (umatshini wokuvavanya jikelele) • Ukuqina kwangaphakathi (i-C-scan immersion ultrasonic, i-single defect equivalent ≤FBH 0.8 mm) • Ubungakanani kunye nomgangatho womphezulu (i-CMM + i-laser micrometer)
● Iinkcukacha zangaphakathi zidlula iimfuno ze-GB/T 33999, EN 755, kunye ne-ASTM B221. Iimpawu eziqhelekileyo eziqinisekisiweyo ze-6061-T6: Amandla okuxinana ≥310 MPa, Amandla okuvelisa ≥275 MPa, Ukwandiswa ≥12% (xa kuthelekiswa nomgangatho we-260/240/8%).
