FAQ
Q1: Vim li cas qhov ua tiav - forging kub rau Nimonic 80A ntau dua 75?
A:Nimonic 80A muaj Aluminium (Al), uas ua rau 'theem. Yog tias koj forge txias dhau lawm, theem no pib los nag, ua rau cov khoom hnyav heev thiab ua rau "stress-induced cracking." Kev tswj qhov kub thiab txias (siab tshaj 1050 degree) khaws cov ntsiab lus hauv kev daws teeb meem.
Q2: Kuv puas tuaj yeem tso cua sov - txias Nimonic 75 tom qab kub forging?
A:Yog lawm, Nimonic 75 yog ib qho khoom siv -solution alloy thiab yog qhov ruaj khov. Txawm li cas los xij, rau Nimonic 80A, kev tswj kom txias lossis dej nrawm nrawm yuav tsum tau nyob ntawm tus ntoo khaub lig-section los txhim kho cov qauv nplej rau kev laus tom ntej.
Q3: Dab tsi yog lub sij hawm txhuas txhuas rau cov kab loj Nimonic?
A:Peb tuav ib tug lojcov khoom hauv Tshuagrau billets txog Φ150mm rautam sim thoob ntiaj teb shipping. Rau kev cai forging khiav mus txog Φ350mm, peb lub sij hawm txhuas raug yog 4-6 lub lis piam.
