Dab tsi yog cov txiaj ntsig ntawm kev siv ob-xim ntsuas kub nyob rau hauv billet steel strip kub dov kev lag luam?
Nyob rau hauv cov txheej txheem kub dov, steel billet yog rhuab nyob rau hauv ib lub qhov cub cua sov kom nws yuav softened thiab ces dov. Yog tias cov hlau kub qis dhau lawm, nws yuav nyuaj heev los tsim cov kab nrib pleb hauv cov txheej txheem dov tom ntej, thiab nws tseem yuav ua rau cov khoom siv dov puas. Thiab yog tias cov hlau kub siab dhau lawm, cov kab nrib pleb, melting lossis blemishes yuav tshwm sim thaum lub sij hawm dov. Yog tias cov hlau tsis sib npaug, cov hlau yuav deform tsis tu ncua, ua rau cov khoom tsis zoo thiab cov khoom seem. Thaum ntsuas qhov kub ntawm cov hlau billet nrog monochromatic infrared tus pas ntsuas kub, muaj kev cuam tshuam xws li daim tawv nqaij oxide thiab dej vapor, ntawm cov emissivity ntawm daim tawv nqaij oxide yog siab, thiab emissivity ntawm steel billet yog tsawg.
Qhov zoo ntawm kev siv ob xim ntsuas kub:
(1) Tsis muaj kev cuam tshuam ntawm emissivity tshwm sim los ntawm daim tawv nqaij oxide.
(2) Ob-xim kub ntsuas tshuab tshem tawm feem ntau ntawm cov dej vapor.
(3) Kev kis tus kab mob me me ntawm lub ntsuas qhov ntsuas kub tsis cuam tshuam rau qhov ntsuas kub.
