Uxinzelelo olushiyekileyo kwiiintsimbi zentsimbingumba obalulekileyo onokuchaphazela ukusebenza kunye nexesha elide lamacandelo ensimbi. Ukuqikelela nokulawula olu xinzelelo lubalulekile ekuqinisekiseni umgangatho kunye nokuqina kwemveliso yokugqibela.
Ukuqikelelwa koxinzelelo lweNtsalela kwiiCastings
Ukuxinezeleka okushiyekileyo kwi-castings kunokuqikelelwa kusetyenziswa iindlela zokubala ezifana nohlalutyo lwento egqityiweyo (FEA). Ezi zifaniso ziqwalasela iinkqubo ze-thermal kunye ne-mechanical ngexesha lokuphosa, kubandakanywa ukuqina kunye nokupholisa.
Ukunciphisa ukusekwa koxinzelelo olushiyekileyo
Ukunciphisa ukubunjwa koxinzelelo olushiyekileyo kwi-castings, iindlela ezininzi zingasetyenziswa. Ukupholisa okulawulwayo yindlela enye, apho ukuphosa kupholiswe ngesantya esifanayo ukukhusela ukunqanyulwa kokwahlukana. Ukuphucula uyilo lokuphosa ukunqanda iikona ezibukhali kunye namacandelo ashinyeneyo nako kunokunceda, njengoko ezi ndawo ziqhelene noxinzelelo oluphezulu. Ukongeza, ukuguqula ukubunjwa kwe-alloy ukufezekisa ukuqina okufanayo kunokunciphisa uxinzelelo.
Ukufunyanwa koxinzelelo lweNtsalela
Ukubona uxinzelelo olushiyekileyo kwi-castings kunokufezekiswa ngeendlela ezahlukeneyo zovavanyo ezingonakalisi. I-X-ray diffraction (XRD) bubuchule obuqhelekileyo obulinganisa isithuba seeplanethi zekristale kwizinto eziphathekayo ukumisela imeko yoxinzelelo. Uvavanyo lwe-Ultrasonic lungasetyenziselwa ukufumanisa utshintsho kwiipropati eziphathekayo ezibonisa uxinzelelo. Iigeyiji zoxinzelelo zingasetyenziswa ukulinganisa ubunzima bomphezulu ngokuthe ngqo.
Isiqabu soxinzelelo kwi-Cast Castings
Ukuphelisa uxinzelelo olushiyekileyo kwiJula i-ayini, i-annealing yindlela esetyenziswa ngokubanzi. Oku kubandakanya ukufudumeza ukuphosa kwiqondo lobushushu elingaphantsi kwendawo yokunyibilika, ukulibamba kwelo qondo lobushushu ukuvumela ukuphumla koxinzelelo, kwaye emva koko ukupholise kancinci. Le nkqubo ivumela ukuba uxinzelelo lwangaphakathi lukhululwe ngaphandle kokuguqula kakhulu izinto eziphathekayo.
Uncedo lweStress kwiSteel Castings
Kubaiicasts zotyalo-mali zentsimbi, ukuthomalalisa uxinzelelo kukwasebenza. Inkqubo iyafana naleyo yentsimbi etyhidiweyo, kodwa amaqondo obushushu abandakanyekayo ngokuqhelekileyo aphezulu ngenxa yeempawu ezahlukeneyo ze-thermal zentsimbi. Ukufudumeza okulawulwayo kunye nokupholisa kubalulekile ukukhusela ukuqaliswa koxinzelelo olutsha ngexesha lenkqubo.
Isiqabu soxinzelelo kwi-Non-Ferrous Alloy Castings
I-alloys engeyiyo i-ferrous, njenge-aluminium kunye ne-alloys yobhedu, nayo ifuna ukukhululeka koxinzelelo ukuze kuphuculwe ukusebenza kwabo. Ezi mathiriyeli ziqhelekile ukuthomalalisa uxinzelelo-ngokusebenzisa iindlela ezishushu ezifana neentsimbi zentsimbi kodwa rhoqo kumaqondo obushushu asezantsi. Ukongezelela, ezinye ii-alloys ezingenayo i-ferrous zinokuzuza kwiindlela zokunciphisa uxinzelelo lwe-mechanical, ezifana nokunciphisa uxinzelelo lwe-vibratory, esebenzisa ii-vibrations zoomatshini ukusabalalisa kwakhona kunye nokunciphisa uxinzelelo lwangaphakathi.
