Indlela yokulawula ukuguqulwa kwe forgings ngexesha unyango ubushushu

Ezinye i-forgings zifuna unyango lobushushu emva kokufudumeza kunye nokukhwabanisa. Ngethuba lokunyanga ukushisa, nikela ingqalelo ekunciphiseni indlela kunye nenani leendawo zokubeka. Enye kukuxhoma ngokuthe nkqo kangangoko. Isikhundla siphakathi kweyesithathu kunye nekota yobude obupheleleyo, kwaye isine sibeka isicaba kwisixhobo sensimbi esinganyangekiyo. Ukubekwa ngokungafanelekanga sesinye sezizathu ze-deformation.

Okwesibini, uhlobo lokupholisa kunye nokucima okuphakathi kunyango lokushisa, ukusebenza kokupholisa, akukho khetho okanye ukusebenza okungafanelekanga konke kuya kuhambelana nokuguqulwa kokuqina. Utshintsho lwentsebenzo yokupholisa lunokutshintshwa ngokutshintsha i-viscosity, ubushushu, uxinzelelo lwe-liquid surface ye-medium, usebenzisa izongezo, ukuvuselela, njl njl. Ukuphakama kwe-viscosity yeoli yokucima kunye nobushushu obuphezulu, i-deformation encinci ye-elliptical. Kwimeko yokuphumla, i-deformation incinci.

Ukongeza, nikela ingqalelo kumandla okutshintsha ubushushu bokucima ngexesha lonyango lobushushu. Iqondo lobushushu ukucima i-oyile-upholile kwiqondo lobushushu ngaphezulu kancinci kunokuba Ms point, ngoko ngokukhawuleza kwaye zigcinwe emoyeni ukwenza ubushushu iyonke inxalenye iyunifomu, kwaye ke oyile-upholile ukwenza iyunifomu inguqu martensitic. I-irregularity of deformation iphuculwe kakhulu.
