摘要
针对700 mm×1 500 mm特厚矩形铸坯二冷制度的水量分配进行研究,根据经验公式初步确定二冷区各段的冷却水量,再由计算的铸坯表面目标温度曲线确定各二冷段的传热系数,并结合有限元仿真模拟,对比结果曲线验证方案的可行性。通过传热系数与水流密度的经验公式,确定各冷却段的水流密度值,最终对二次冷却水量进行优化。
Aimed at water allocation of 700 mm×1 500 mm thick rectangular billet in secondary cooling zone, according to experience formula, the cooling water of the secondary cooling zone paragraphs was preliminary determined, then the heat-transfer coefficient of the secondary cooling period was determined according to the calculated temperature curve of slab target surface, and combining with the finite element simulation, the feasibility of the scheme was verified. The water-flow density value of each cooling section was determined through the experience formula of the heat-transfer coefficient and water-flow density, finally the secondary cooling water was optimized.
