Plhaw kev kuaj
Cov leeg hlau nrog sab nraud uas hla ntau dua 22 hli thiab txog li 400 hli, thiab phab ntsa tuab ntau dua 10 hli yuav tsum yauv mus kuaj flattening. Tom qab cov qauv ntsuas yog pluav
Dabtsi yog khoov xeem
Tub txheej hlau nrog ib txoj kab uas hla sab nraud Dabtsi yog khoov kaum sab xis yog 90o. Kev khoov lub vojvoog yog 6 lub sij hawm sab nraud ntawm cov hlau raj.Amter khoov cov qauv, tsis muaj kev sib tsoo lossis cov kab nrib pleb muaj kev tso cai tshwm sim ntawm cov qauv.
Macroscopic kuaj
Rau cov hlau tub sab ncaj qha ua los ntawm cov pob zeb ua kom tsis tu ncua lossis txheej txheem ntawm cov pob ntoo uas tsis muaj roj av pickled macroscopic nqaij ntawm cov billet lossis steel raj.
Tsis Yog-Phom Sij
Raws li kev thov tog neeg thov, uas yog tom qab ntawd sib tham ntawm kev muab thiab xav tau nyob rau hauv cov lus pom zoo, ultrasonic khuam nrhiav yuav yog tus kheej ua rau cov leeg hlau. Kev tuav ntaub ntawv ntev los ntawm cov neeg siv lub raj tsim nyog yuav tsum ua kom tau raws li qhov yuav tsum tau ua rau tom qab C8 teev hauv GB / T 5777-1996.
