Inhloso yokushisa kwesithando sokungenisa
Inhloso ye ukushisa kwesithando sokungenisa
Izithando zokungenisa izinto zisebenzisa umgomo wokushisisa okungeniswa yi-electromagnetic ukushisisa izinto zokusebenza zensimbi, futhi ngokuvamile zisetshenziswa kabanzi ekwenzeni insimbi, ukuphonsa, ukugxiviza okushisayo, ukugingqika okushisayo kanye nokucisha insimbi nokufudumeza ukushisa.
Lapho isithando somlilo sokungeniswa sishisisa i-workpiece, okokufaka komthombo wokushisa wangaphandle kuzobangela ukuguqulwa kwesimo samandla sangaphakathi sokungenalutho. Njengoba izinga lokushisa likhuphuka, amandla e-kinetic ama-athomu ayanda, futhi amathuba okushiya indawo yawo yokulinganisa nawo ayanda. Uma kuqhathaniswa nezinga lokushisa elivamile, ukugudluka kulula Ukuhamba, ukushelela kulula, futhi ukumelana ne-deformation kuyancipha; ngaphezu kwalokho, ukuhamba kwama-athomu aphezulu okushisa kuyanda, isivinini sokusabalalisa siyasheshisa, ukululama nokuvuselela kabusha kulula, futhi ukubunjwa kwensimbi kuyathuthukiswa; ngaphezu kwalokho, ukuhamba kwama-athomu kuyanda ekushiseni okuphezulu, futhi ijubane lokusabalalisa liyashesha. , kulula ukubuyisela nokuvuselela kabusha, futhi ipulasitiki yensimbi iyathuthukiswa; lapho izinto ezinokuguqulwa kwe-allotropic zishisisiwe, kunezinqubo ezifana nokuguqulwa kwesigaba, ukuguqulwa kwekristalu nokuqedwa kwesigaba ebangeni elithile lokushisa. Eqinisweni, ukushisa kwesithando sokufakelwa kwe-induction ukuxazulula izinkinga ezimbili zokubunjwa nokumelana nokuguqulwa kwezinto zokusebenza zensimbi;
Inhloso yokushisisa kwesithando somlilo ukusebenzisa ngendlela efanele umthetho wokuziphendukela kwemvelo we-microscopic ngesikhathi senqubo yokushisisa ucezu lwensimbi, ukuthuthukisa ipulasitiki yensimbi, futhi ngesikhathi esifanayo uthole ukwakheka okuhle kwangemuva kokufoja nokusebenza. Ukushisa kwesithando somlilo we-induction kuyisixhumanisi esibalulekile kuyo yonke insimbi yokubumba, ukuphonsa, ukunyathela okushisayo, ukugoqa okushisayo kanye nenqubo yokucisha insimbi kanye nenqubo yokushisa, enomthelela oqondile ekuthuthukiseni ukukhiqiza, ukuqinisekisa izinga lokushisa kanye nokonga ukusetshenziswa kwamandla.
Isibonelo, ukumelana nokuguqulwa kwensimbi engagqwali i-12Cr18Ni9 ekamelweni lokushisa ngu-640MPa, ukumelana nokuguqulwa kwensimbi engagqwali 12Cr18Ni9 kuncishiswa kuze kufike ku-120MPa lapho kushiswa ku-800 ℃ esithandweni sokungeniswa, futhi ukumelana nokuguqulwa kwehle kuze kufike ku-20MPa lapho ishisa. I-1200 ℃, ephansi ngo-97% kunaleyo ekamelweni lokushisa. .
