Forgingszisetyenziswa kakhulu kwishishini, njengenqwelomoya, iimoto njalo njalo. Kanjalo,forgingsnazo kufuneka zicocwe, oku kulandelayo ikakhulu kukuxelela malunga nolwazi pickling nokudubula forgings ukuqhushumba.
Ukuvunwa kunye nokucoca iifogi:
Ukususwa kweeoksidi zetsimbi ngokusabela kweekhemikhali. Kwi-forgings encinci kunye ne-medium-sized forgings idla ngokulayishwa kwibhasikithi kwiibhetshi, emva kokususwa kweoli, i-pickling corrosion, ukuhlanjululwa, ukumisa kunye nezinye iinkqubo.
Indlela ye-pickling ineempawu eziphezulu zokuvelisa, umphumo wokucoca kakuhle, akukho deformation of forgings kunye nesimo esingathinteliyo. I-Pickling chemical reaction process ngokuqinisekileyo iya kuvelisa iigesi eziyingozi, ngoko ke, igumbi lokukhetha kufuneka libe nesixhobo sokukhupha. Ukuchola iintsimbi ezahlukeneyo kufuneka ukhethe i-asidi eyahlukeneyo kunye nomlinganiselo wokubunjwa ngokweempawu zetsimbi, kwaye wamkele inkqubo yokuchola ehambelanayo (ubushushu, ixesha kunye nendlela yokucoca).
Ukuqhushumba kwesanti (ukudubula) kunye nokucoca ukuqhushumba:
Ikakhulu ngokusekelwe kumoya oxinanisiweyo njengamandla okudubula kwesanti (ukudubula), yenza isanti okanye ukudubula kwentsimbi kuvelise intshukumo enesantya esiphezulu (i-sandblasting isebenze uxinzelelo lwe-0.2 ~ 0.3Mpa, i-0.5 ~ 0.6Mpa) i-jet umphezulu wokwakha ukubetha isikali seoksidi. Ukudutyulwa kokudubula kwenziwa ngesantya esiphezulu (2000 ~ 30001r/min) amandla ajikelezayo e-centrifugal ye-impeller, intsimbi yadutyulwa kumphezulu wobumbi ukuwisa isikali se-oxide.
Uthuli lwe-Sandblasting, ukusebenza kakuhle kwemveliso ephantsi, iindleko eziphezulu, ezisetyenziselwa iimfuno ezikhethekileyo zobugcisa kunye nezinto ezikhethekileyo zokubumba (ezifana nensimbi engenasici, i-titanium alloy), kodwa kufuneka ithathe amanyathelo obugcisa okususa uthuli. I-shot peening icocekile ngokwentelekiso, kukwakho nezingeloncedo kwimveliso ephantsi kunye neendleko eziphezulu, kodwa umgangatho wokucoca uphezulu. Ukudubula kwe-shot kusetyenziswa ngokubanzi ekusebenzeni kwayo okuphezulu kunye nokusetyenziswa okuphantsi.
Oku ngasentla kulwazi lokubumba i-pickling kunye nokudutyulwa kokudubula. Ndiyathemba ukuba iya kuba luncedo kuwe.
