Aluminium Round Bar - Polelo ea Ts'ebetso le Netefatso ea Boleng

Li-bar tsa rona tse chitja tsa aluminium li entsoe ka li-ingot tsa aluminium tsa mantlha tse hloekileng ≥99.7%. Tsela e felletseng ea tlhahiso ke e latelang:
1. Ho Qhibilihisa le ho Hloekisa: Sebōpi sa ho qhibilihisa ka vacuum se kopantsoeng le ho tlosa khase ka har'a mola le ho sefa foam ea ceramic ho netefatsa hore na haeterojene e na le bokae ka ho sa fetoheng ≤0.12 ml/100g Al, e leng se fellang ka ho hloka masoba le ho kenngoa ha lintho.
2. Ho lahla ka mokhoa o sa fetoheng: Ho lahla ka mokhoa o chesang ka holimo ka taolo ea boemo ba hlobo ka boiketsetso; lera la karohano ≤3 mm, boholo ba lijo-thollo Kereiti ea 1.
3. Homogenization: Homogenization ea gradient ea lihora tse 12-18 e felisa karohano ea dendritic le khatello e setseng.
4. Ho ntsha oli: 6500–12500 T e hatisang oli-hydraulic, e ntshang oli ka pele ka ho tima metsi le moea inthaneteng. Ho beha leihlo mocheso oa setshelo le oa ho tsoa ka nako ea sebele ho netefatsa mamello ea boholo bo kahare ho ± 0.15 mm (sehlopha se phahameng sa ho nepahala, se phahametseng litlhoko tse tloaelehileng).
5. Ho Otlolla le Botsofali ba Maiketsetso: Ho otlolla rolara e kopaneng + ho otlolla ho fihlella ho otloloha ≤0.3 mm/m. Botsofali ba T6/T6511 bo etswa ka diontong tse nang le ho lekana ha mocheso ±3 °C; phapang ya thepa ya mechini pakeng tsa dihlopha ≤5 MPa.
6. Qetello: Ho sila ntle le setsi, ho ebola, ho seha ka nepo. Bophara ba φ8–650 mm, qetello ya bokahodimo Ra ≤0.4 μm, mamello ya bolelele ±0.5 mm.

Sistimi ea Taolo ea Boleng

● Ho latela palo e felletseng ea mocheso oa ingot ho ea ho bareng e felileng
● Ho bolokoa ha disampole tsa lipaki tse ≥lilemo tse 2 bakeng sa tlhahlobo e ncha ea motho oa boraro (SGS, BV, TÜV, jj.)
● Tlhahlobo ea 100% ea liparamente tsa bohlokoa: • Sebopeho sa lik'hemik'hale (spectrometer e balang ka ho toba) • Thepa ea mechini (mochini o lekang oa bokahohle) • Ho utloahala ha ka hare (C-scan ultrasonic immersion, e lekanang le sekoli se le seng ≤FBH 0.8 mm) • Boleng ba litekanyo le bokaholimo (CMM + micrometer ea laser)
● Litlhaloso tsa kahare li feta litlhoko tsa GB/T 33999, EN 755, le ASTM B221. Thepa e tloaelehileng e netefalitsoeng bakeng sa 6061-T6: Matla a ho tsikinyeha ≥310 MPa, Matla a tlhahiso ≥275 MPa, Ho lelefatsa ≥12% (ha ho bapisoa le maemo a tloaelehileng a 260/240/8%).
