连铸是钢水直接铸成接近最终产品尺寸钢坯的过程,比铸锭成型再加热轧制过程节省大量的时间,于轧制成形节省切废,提高钢水的收得率,直接轧制,更加节省能源。连铸过程包含一次冷却与二次冷却,二次冷却是指钢坯从出结晶器开始到完全凝固这一过程。在此过程中,冷却水加热与蒸发所放出的热量占到总的钢水成形排放量的55%。喷嘴的设计对二次冷却效果至关重要。2喷嘴应用及其流量特性
Continuous casting is the direct casting of molten steel into the final product size of the billet process, compared with the ingot molding reheating and rolling process to save a lot of time, save the cut in the rolling forming waste, improve the yield of molten steel, direct rolling, more savings energy. Continuous casting process includes a cooling and secondary cooling, secondary cooling refers to the billet from the beginning of the mold to completely solidified this process. During this process, the heat released by the cooling water heating and evaporation accounted for 55% of the total molten steel forming emissions. The nozzle design is crucial to the secondary cooling effect. 2 nozzle application and its flow characteristics
