Residual stress inmetal castingsinyaya yakakosha inogona kukanganisa kushanda uye hupenyu hurefu hwezvikamu zvesimbi. Kufanotaura nekugadzirisa izvi zvinonetsa kwakakosha pakuve nechokwadi chemhando uye kusimba kwechigadzirwa chekupedzisira.
Kufanotaura Kwekusara Kwekushushikana muCastings
Kusarira kushushikana mukukanda kunogona kufanotaurwa uchishandisa nzira dzemakomputa senge finite element analysis (FEA). Aya mafananidziro anofunga nezve kupisa uye mechanical maitiro panguva yekukanda, kusanganisira kusimba uye kutonhora.
Kuderedza Kuumbwa Kwekusara Kwekushushikana
Kuti kuderedze kuumbwa kwekusarira kunetseka mukukanda, nzira dzinoverengeka dzinogona kushandiswa. Kutonhodzwa kunodzorwa ndiyo imwe nzira, apo kukanda kunotonhodzwa pamwero weunifomu kudzivirira kupesana kwekupesana. Kugadziridza dhizaini yekukanda kudzivirira makona akapinza uye zvikamu zvakakora zvinogona kubatsira, sezvo nzvimbo idzi dzinowanzoita zvakanyanya kushushikana. Pamusoro pezvo, kushandura iyo alloy kuumbwa kuti uwane yakawedzera yunifomu kusimba kunogona kuderedza kushushikana.
Kuonekwa kweResidual Stress
Kuona kusara kunetseka mukukanda kunogona kuwanikwa kuburikidza neakasiyana-siyana asiri ekuparadza ekuedza nzira. X-ray diffraction (XRD) inzira yakajairika inoyera kupatsanurwa kwendege dzekristaro muzvinyorwa kuona mamiriro ekushushikana. Ultrasonic bvunzo inogona zvakare kushandiswa kuona shanduko yezvinhu zvinoratidza kushushikana. Mageji ekusevha anogona kuiswa kuyera madhiri epamusoro zvakananga.
Stress Relief muCast Iron Castings
Kubvisa zvakasara kushushikana mukatisimbi yakakandwa, annealing inzira inoshandiswa nevakawanda. Izvi zvinosanganisira kudziyisa kukanda kune tembiricha iri pazasi pekunyungudika kwayo, kuibata patembiricha iyoyo kuti ibvumire kuzorora kwekushushikana, uye nekuitonhodza zvishoma nezvishoma. Iyi nzira inobvumira kushushikana kwemukati kusunungurwa pasina kushandura zvakanyanya zvinhu zvemukati.
Stress Relief muSimbi Castings
Forsimbi mari castings, stress annealing inobatsirawo. Maitiro acho akafanana neaya esimbi yakakandwa, asi tembiricha inosanganisirwa inowanzokwira nekuda kwekusiyana kwekupisa kwesimbi. Kudzora kupisa uye kutonhora kwakakosha kudzivirira kuunzwa kwekushushikana kutsva panguva yekuita.
Stress Relief muNon-Ferrous Alloy Castings
Non-ferrous alloys, akadai sealuminium nemhangura alloys, inodawo kusununguka kwekunetseka kuti vawedzere kushanda kwavo. Zvishandiso izvi zvinowanzo kudzoreredzwa-kudzoreredzwa kuburikidza nezvinopisa nzira dzakafanana nesimbi dzesimbi asi kazhinji pakudzika kwakadzika. Pamusoro pezvo, mamwe asiri-ferrous alloys anogona kubatsirikana kubva kumakanika ekugadzirisa kushushikana kwemaitiro, senge vibratory stress relief, iyo inoshandisa ma mechanical vibrations kugovera zvakare uye kudzoreredza kushushikana kwemukati.
