Tsom ntawm qhov Micro-kab nrib pleb ntawm Steel phaj

Deg micro-cracking ib feem ntau ntawm cov khoom zoo, xws li commuted, hnyav seem, tshwj xeeb tshaj yog muaj niobium, vanadium, titanium phaj steel phaj yog feem ntau mas, loj tej yam nyob rau hauv txoj kev txhim kho cov khoom zoo thiab yield. Tsis tas coj economic losses loj loj rau tus enterprise, tiam sis yuav txwv tsis pub cov kab ntau lawm nruab nrab thiab hnyav phaj Ej. Deg micro nrib pleb ntawm phaj ntug cracking, longitudinal, zoo li lub hnub qub tus speed, ua rau nws muaj ob txheej txheem ntxuag tsis tswj, nruam casting ntau lawm, caj thiab residual slab nrib pleb caij Day.
Deg micro-cracking loj feem ntawm yam khoom zoo. Scholars los ntawm cov kab nrib pleb hlau Chongqing thiab hlau lag luag tsom, metallographic soj casting thiab steel phaj thiab zog spectrum (eds), kuaj, thiab ntau lawm txheej txheem tsis tau q345a (thickness) ntawm qhov micro-kab nrib pleb ntawm qhov chaw steel phaj mas vim nruam casting tooj liab mould phaj txheej poob. Qhov no yuav ua tau kom tooj liab allergic rau hauv lub plhaub ntawm tus austenite lis Area, lis ciam speed yuav tawg vim thermal kev nyuab siab nyob rau ntawm lwm tes, thiab TI-speed cojua uas yog raug rau cov hlau khees. Tiv thaiv kab mob li cas: kev txhim kho kev Crystallizer tooj liab, kom tiv thaiv txhob nqus tooj liab; ua ntej yuav ntau lawm rau slab zoo coated tooj liab ntawv thiab ntau lawm nrog xyuas kev ntsuas xws li casting, kev txhim kho txoj kab huv ntawm molten hlau.
