Forgingsyog dav siv hauv kev lag luam, xws li aircraft, tsheb thiab lwm yam. Tau kawg,forgingstseem yuav tsum tau ntxuav, cov hauv qab no feem ntau yog qhia rau koj txog kev paub txog pickling thiab tua blasting forgings.
Pickling thiab tu ntawm forgings:
Kev tshem tawm cov hlau oxides los ntawm cov tshuaj tiv thaiv. Rau me me thiab nruab nrab forgings feem ntau yog loaded rau hauv lub pob tawb hauv batch, tom qab tshem tawm roj, pickling corrosion, yaug, ziab thiab lwm yam txheej txheem.
Txoj kev pickling muaj cov yam ntxwv ntawm kev ua haujlwm siab, ua haujlwm zoo, tsis muaj deformation ntawm forgings thiab tsis txwv cov duab. Pickling tshuaj tiv thaiv txheej txheem yuav inevitably tsim teeb meem gases, yog li ntawd, lub pickling chav tsev yuav tsum muaj cov pa tawm. Pickling sib txawv hlau forgings yuav tsum xaiv cov kua qaub sib txawv thiab muaj pes tsawg leeg raws li cov khoom siv hlau, thiab txais yuav cov txheej txheem pickling sib xws (kub, sijhawm thiab tu txoj kev).
Forging xuab zeb blasting (steev) thiab tua blasting tu:
Feem ntau raws li cov huab cua compressed raws li lub zog ntawm sandblasting (steev), ua rau cov xuab zeb los yog hlau txhaj tshuaj uas tsim high-ceev txav (sandblasting ua hauj lwm siab ntawm 0.2 ~ 0.3Mpa, tua peening ua hauj lwm siab ntawm 0.5 ~ 0.6Mpa), dav hlau mus rau lub forging nto los tuav cov nplai oxide. Kev txhaj tshuaj blasting yog los ntawm kev kub ceev (2000 ~ 30001r / min) rotating centrifugal quab yuam ntawm lub impeller, cov hlau txhaj tshuaj mus rau lub forging nto los khob tawm lub oxide nplai.
Sandblasting hmoov av, tsis tshua muaj kev ua tau zoo, tus nqi siab, siv ntau dua rau cov kev cai tshwj xeeb thiab cov ntaub ntawv tshwj xeeb forgings (xws li stainless hlau, titanium alloy), tab sis yuav tsum tau txais cov kev ntsuas kev tshem tawm plua plav. Kev txhaj tshuaj peening yog qhov huv si, kuj tseem muaj qhov tsis zoo ntawm kev tsim khoom qis thiab tus nqi siab, tab sis kev tu kom zoo dua. Kev txhaj tshuaj blasting yog dav siv rau nws cov khoom siv ntau lawm thiab kev siv tsawg.
Cov saum toj no yog kev paub txog forging pickling thiab tua blasting. Kuv vam tias nws yuav pab tau koj.
