I-Annealing iwukwelashwa okushisayo kokushisisa i-die steel ku-Ac3 (hypo-eutectoid steel) noma i-Accm (eutectoid ne-hyper-eutectoid steel) ngaphezu kuka-30~50°C, ukuthola i-austenite, ukupholisa emoyeni, nokwelashwa kokushisa kwesakhiwo esifana nesakhi esiqukethe. umsebenzi we-pearlite.
Inhloso yokujwayela: ukujwayela kwensimbi yokufa ukuthuthukisa ukusebenza kahle, ukuqeda amaphutha okusebenza ashisayo, ukuqeda i-carbide yenethiwekhi ku-hypereutectoid die steel, ukulungiselela ukwakheka kwe-spheroidizing annealing, kanye nokwenza ngcono izakhiwo zemishini ye-die.
I-Annealing inqubo yokwelapha ukushisa lapho i-die steel ishiselwa ezingeni lokushisa elingaphezulu noma ngaphansi kwephuzu elibalulekile i-Ac1, bese ipholiswa kancane ngezinga lokushisa lesithando somlilo ngemva kokugcinwa kokushisa ukuze kutholwe isakhiwo esiseduze sokulingana.
Inhloso ye-annealing: Inhloso enkulu iwukuba i-homogenize ukwakheka kwamakhemikhali kanye nesakhiwo se-die steel, ukucwenga okusanhlamvu, ukulungisa ukuqina, ukuqeda ukucindezeleka nokusebenza kanzima, ukuthuthukisa ukwakheka kanye nokusebenza kwensimbi, nokulungiselela isakhiwo sokucisha. .
I-Die steel annealing classification: Izinhlobo ze-Die steel annealing zifaka phakathi i-diffusion annealing, i-isothermal annealing, i-annealing engaphelele, i-spheroidizing annealing, i-recrystallization annealing kanye ne-stress annealing.
