Ukolulwa

I-post annealing, iimpahla zigqithiswa kumatshini wokulungelelanisa we-roller ezisixhenxe ukuze kuphunyezwe ukulungiswa okufanelekileyo kweetyhubhu.

Eddy yangoku

Ukolulwa kwesithuba, ityhubhu nganye idlula kumatshini we-eddy wangoku ukubona iintanda kunye nezinye iziphene.Iityhubhu kuphela ezidlula i-eddy current zilungele ukuhanjiswa kubathengi.

Ukugqiba

Ityhubhu nganye ifakwe i-oyile enganyangekiyo okanye inevanishi yokukhusela umphezulu kunye nokunganyangeki kwe-corrosion ngokwemfuno yabathengi, isiphelo setyhubhu nganye sigqunywe ngee-caps zeplastiki zokuphela kokuphela kokuphela komonakalo, ukumakishwa kunye ne-specs zibekwe kwaye iimpahla zilungele ukuthunyelwa. .
