Intermediate annealing feem ntau yog los tshem tawm kev ua haujlwm nyuaj. Qhov kub-dov aluminium ntawv ci dawb dov los ntawm 750μ rau 15μ, tag nrho cov txheej txheem tau mus txog 98%, thiab lub zog tensile tau txog li 180MPa. Nyob rau hauv txoj kev no, thaum lub sij hawm dov txheej txheem ntawm cov khoom tiav, thinning kuj nyuaj thiab slipping feem ntau tshwm sim.
Lwm lub luag haujlwm tseem ceeb ntawm nruab nrab annealing yog txo cov pinholes hauv cov khoom tiav. Cov ntaub ntawv pov thawj pom tau tias thaum kub-kuav los tiag blanks dov rau hauv ob-zero txhuas ntawv ci, dov pinholes yog ob npaug tom qab nruab nrab annealing.
Roll tswj
Rolls yog ib qho tseem ceeb ntawm cov txheej txheem dov, thiab cov yob ruaj khov zoo yog lub hauv paus rau kev ruaj khov dov. Cov txheej txheem tseem ceeb
Yog li ntawd, qhov nruab nrab annealing feem ntau yog npaj ua ntej cov khoom tiav dhau los kom txo cov khoom siv hluav taws xob ntawm aluminium ntawv ci los ntawm 160 ~ 180MPa rau 120 ~ 140MPa. Vim tias qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. Tsis tas li ntawd, qhov kub ntawm qhov chaw deformation yog siab thaum lub sij hawm plaub-thooj ntau lawm, uas txo cov degree ntawm kev ua hauj lwm hardening ntawm aluminium ntawv ci. Yog li ntawd, qhov nruab nrab annealing kub yog siab dua li ntawm tsib-dhau dov. Tsawg me ntsis thaum lub sij hawm ua ntej lawm.
