Bophara bo boholo ba C93200 Tin e nang le Lead Bronze Tube - Bearing Grade Alloy

Tin e Kholo ea Boronse Bar (Φ120mm le ho feta) – Tlatsetso ea Tekheniki

Re ikhethile tlhahisong ea li-bar tsa boronse tsa tin tse bophara bo boholo tse tlohang ho Φ120mm ho isa ho Φ650mm. Mekhahlelo e meholo e kenyelletsa C51900, C52100, C51000, CuSn6, CuSn8, ZCuSn5Pb5Zn5, ZCuSn10Zn2, jj. Thepa e ka fanoa ho GB/T 13808, ASTM B505, JIS H3270, EN 1982, kapa k'hemistri le thepa tse ikhethileng ka botlalo ho latela litlhoko tsa bareki.

Mokhoa oa Bohlokoa oa Tlhahiso

● Ho lahla ka mokhoa o sa khaotseng ho lateloa ke ho ntša metsi ka mokhoa o boima (boima ba bar e le 'ngoe ke lithane tse 3-8) ho netefatsa sebopeho se teteaneng ka botlalo ntle le ho fokotseha ha marotholi ka bophara bo boholo.
● Mosebetsi o chesang/o batang o fetang ka makhetlo a mangata o kopantsoeng le ho hlohlona ha methapo ho laolwang hantle ho felisa sebopeho sa dendritic, ho fellang ka matrix ea eutectoid ea α+(α+δ) e homogeneous ka boholo ba lijo-thollo tse tloaelehileng tsa 0.025–0.050 mm.
● Bara eohle ha e na sekoli ebile ha e na manonyeletso ho pholletsa le bolelele ba eona.

Lintlha-khōlō tsa Taolo ea Boleng

● Sebopeho sa lik'hemik'hale: Tlhahlobo ea spectrometer ea ho bala ka ho toba (SPECTRO) e etsoang mochesong o mong le o mong; likarolo tsohle tse latelang (P, Fe, Sb, Bi, jj.) li laoloa ho fihlela ho 50% ea meeli e tloaelehileng kapa e tiileng haholoanyane.
● Thepa ea mechini: Litekanyetso tse tloaelehileng bakeng sa li-bar tsa Φ≥200mm: Matla a ho tensile ≥450 MPa, matla a tlhahiso ea 0.2% ≥200 MPa, ho lelefatsa ≥15%, ho thatafala HB120–180 (ho netefalitsoe ka botlalo).
● Boleng ba kahare: Teko ea ultrasonic ea 100% ho latela boemo ba ASTM B594 Sehlopha sa A kapa SEP 1921 E/e ho sebelisoa li-probe tsa 6-10 MHz. Litlaleho tse felletseng tsa UT le linepe tsa macro/microstructure lia fumaneha ka bareng ha li kopuoa.
● Litekanyetso tsa litekanyo: Boima ba ho mamella ± 0.5 ho isa ho ± 1.5 mm (ho feta H11), ho otloloha ≤1 mm/m, mamello ea bolelele ba ho khaola ± 20 mm.
● Qetello ea bokaholimo: E fetotsoe ka nepo kamora ho ntšoa ha lintho, ho ba thata ha bokaholimo Ra ≤3.2 μm, e se nang mapetso, lintho tse kenyellelitsoeng, kapa liphoso tse nang le lekhapetla la lamunu.

Litšupiso tsa Phepelo

● Li-propeller tse kholo tsa metsing (li-bars tsa CuSn10Zn2 tse le 'ngoe tsa lithane tse 3–5)
● Likhokahano tsa sehahi sa potoloho se nang le motlakase o phahameng (CuSn6/CuSn8)
● Mekhoa ea liphaephe tsa metsi a leoatle (C51900 bophara bo boholo)
● Boronse ea tin-phosphorus e matla haholo bakeng sa lipalangoang tsa terene le lits'ebetso tsa matla a moea

Nako ea ho etella pele: Matsatsi a 30–45 bakeng sa lintho tse tloaelehileng, matsatsi a 20 a ka khonehang bakeng sa liodara tse potlakileng ka kemiso e khethehileng. Tsamaiso ea fektheri le tlhahlobo ea boleng lia amoheleha kamehla.
