Ibha Eyindilinga Ye-aluminium Eyengeziwe engu-6061 – Isitoko Sokushisa se-T6

Ibha Eyindilinga Ye-Aluminium - Isitatimende Sokuqinisekisa Inqubo Nekhwalithi

Imigoqo yethu eyindilinga ye-aluminium yenziwe ngama-ingot e-aluminium ayisisekelo ahlanzekile ≥99.7%. Indlela ephelele yokukhiqiza imi kanje:
1. Ukuncibilikisa Nokucwenga: Isithando sokuncibilikisa se-vacuum esihlanganiswe nokususa igesi emgqeni kanye nokuhlunga i-ceramic foam kuqinisekisa okuqukethwe kwe-hydrogen njalo okungu-≤0.12 ml/100g Al, okuholela ekutheni kungabikho ukubhoboka kanye nokufakwa.
2. Ukuphonsa Okuqhubekayo: Ukuphonsa Okushisayo Okusezingeni elifanayo ngokulawula okuzenzakalelayo kwezinga lesikhunta; ungqimba lokuhlukanisa ≤3 mm, usayizi wezinhlamvu Ibanga 1.
3. Ukuhlanganiswa kwe-homogenization: Ukuhlanganiswa kwe-gradient kwamahora angu-12-18 kuqeda ukuhlukaniswa kwe-dendritic kanye nokucindezeleka okusele.
4. Ukwehliswa: Ukucindezela kukawoyela-hydraulic okungu-6500–12500 T, ukwehliswa phambili okune-quench yokuvala amanzi nomoya eku-inthanethi. Ukuqapha izinga lokushisa lesitsha kanye nokuphuma ngesikhathi sangempela kuqinisekisa ukubekezelelana kobukhulu ngaphakathi kuka-±0.15 mm (izinga lokunemba okuphezulu, elingcono kunezidingo ezijwayelekile).
5. Ukwelula kanye nokuguga kokwenziwa: Ukuqondisa okuhlanganisiwe kwe-roller kanye nokuqina kokudonsa kufeza ukuqondile okungu-≤0.3 mm/m. Ukuguga kwe-T6/T6511 kwenziwa ezithandweni ezinokulingana kwezinga lokushisa okungu-±3 °C; ukuhlukahluka kwesakhiwo somshini phakathi kwamaqoqo angu-≤5 MPa.
6. Ukuqeda: Ukugaya okungenasikhungo, ukuhlubula, ukusika ngokunemba. Ububanzi bebanga φ8–650 mm, ukuqeda ubuso Ra ≤0.4 μm, ukubekezelela ubude ±0.5 mm.

Uhlelo Lokulawula Ikhwalithi

● Ukulandelela okugcwele kwenani kusukela enombolweni yokushisa ye-ingot kuya kubha eqediwe
● Ukugcinwa kwamasampula ofakazi ≥iminyaka engu-2 ukuze kuhlolwe kabusha umuntu wesithathu (i-SGS, i-BV, i-TÜV, njll.)
● Ukuhlolwa okungu-100% kwamapharamitha abalulekile: • Ukwakheka kwamakhemikhali (i-spectrometer yokufunda ngqo) • Izakhiwo zemishini (umshini wokuhlola ojwayelekile) • Ukuqina kwangaphakathi (i-C-scan immersion ultrasonic, okulingana nesici esisodwa ≤FBH 0.8 mm) • Ikhwalithi yobukhulu kanye nobuso (i-CMM + i-laser micrometer)
● Imininingwane yangaphakathi idlula izidingo ze-GB/T 33999, EN 755, kanye ne-ASTM B221. Izakhiwo ezijwayelekile eziqinisekisiwe ze-6061-T6: Amandla okunamathela ≥310 MPa, Amandla okukhiqiza ≥275 MPa, Ukwelulwa ≥12% (uma kuqhathaniswa no-260/240/8%) ojwayelekile.
