Tsieina OEM impeller dur gwrthstaen personol ganproses castio buddsoddiad cwyr coll.
Elfennau aloi sylfaen unrhyw gastio buddsoddiad nicel-sylfaen neu ddur di-staen yw cromiwm, nicel, a molybdenwm (neu "moly"). Bydd y tair cydran hyn yn pennu strwythur grawn a phriodweddau mecanyddol y castio a byddant yn allweddol i allu'r castio i frwydro yn erbyn gwres, gwisgo a chorydiad.
Mae gan ddur di-staen gynnwys cromiwm lleiafswm o 10.5%, gan ei gwneud yn fwy gwrthsefyll amgylcheddau hylif cyrydol ac ocsideiddio. Fodd bynnag, nid yw hyn yn absoliwt. Buddsoddiad dur di-staenmae castiau yn "gwrthsefyll cyrydiad" pan gânt eu defnyddio mewn amgylcheddau hylif ac anweddau o dan 1200 ° F (650 ° C) ac yn "gwrthsefyll gwres" pan gânt eu defnyddio uwchlaw'r tymheredd hwn.
Manteision Cydrannau Castio Buddsoddiadau:
- Gorffeniad arwyneb rhagorol a llyfn
- Goddefiannau dimensiwn tynn.
- Siapiau cymhleth a chymhleth gyda hyblygrwydd dylunio
- Y gallu i fwrw waliau tenau felly yn elfen castio ysgafnach
- Dewis eang o fetelau cast ac aloion (fferrus ac anfferrus)
- Nid oes angen drafft yn nyluniad y mowldiau.
- Lleihau'r angen am beiriannu eilaidd.
- Gwastraff deunydd isel.
