摘要: 以大板坯連鑄結晶器為研究對象,采用水模型和數值模擬的方法研究了不同水口出口角度對結晶器內鋼液流動的影響.結果表明:現行15°水口在距結晶器邊部50 mm的位置,表面流速和波高較小,傳遞給彎月面的熱量較少,不利于保護渣的熔化;射流撞擊到結晶器窄邊的位置較深,壓力較大,對撞擊點下部坯殼的沖擊力也較大;水口出口角度改為10°后,結晶器漏鋼預報系統的報警次數大大減少,杜絕了漏鋼的事故.

Abstract: Water modeling and numerical simulation were applied to investigate the influence of the port angle of a submerged entry nozzle (SEN) on the flow pattern in a slab continuous casting mold. The results indicate that under the current 15° SEN, the surface velocity and fluctuation are relatively small at meniscus, which does harm to the melt of mold powder. The impinging point of jet flow streaming from the SEN is relatively low. Below the point, the pressure on the solidifying shell is relatively high. The sharply decreasing frequency of breakout alarms and no breakout were achieved after a new 10° SEN was put into operation.
