Stellite 6 los yog cobalt 6 cobalt raws li alloysua los ntawm centrifugal casting los yog xuab zeb moulding, siv rau hauv bushings thiab hnav rings los txhim kho hnav tsis kam.
Qhov xwm txheej:Casting, txo kev ntxhov siab ua ntej ua
Kev kho cua sov:Kev ntxhov siab: ua kom sov lub casting mus rau qhov tsawg kawg nkaus 800 ℃, tuav rau 1-4 teev qeeb txias.
Txheej txheem: Tag nrho cov castings ntawm tib batch yuav tsum zoo tib yam yam tsis muaj pores, pores, tawv me ntsis, shrinkage defects, tawg los yog lwm yam teeb meem tsis xws luag.Single castings nrog cais qhov hauv qab no 0.5 hli tsis pub kho, ntsaws los yog welded.
Semi-tiav castings rau EMS zaum kawg machining yuav tsum tau muab nyob rau hauv "Machining Inspection Status" kom tso cai rau kev kuaj xyuas ua ntej xa khoom.

Daim ntawv thov:
Stellite6B alloy yog ib qho ntawm cov cobalt-raws li hnav resistant Bai alloys, hnav tsis kam thiab toughness, tuaj yeem hloov mus rau feem ntau cov mob, ntau yam kev siv, hardness hauv 37-45HRC; Nws yog tsuas yog siv rau cov tshuaj hnav-tiv taus phaj, hnav- resisting pas nrig, chav chemical valve lub rooj, chav turbine hniav tiv thaiv, tiv thaiv yaig bushing, kub dip galvanized submerged cov menyuam thiab lwm qhov chaw; Piv nrog WR6 (Stellite6) WR6B, WR6B tau zoo dua kub hnav tsis kam
