【摘要】 介绍了连铸坯冷却的冶金准则，以小方坯和板坯连铸为例，详细讲述了二冷制度优化的目标、表面温度反算法和冶金冷却准则函数优化法，并对连铸二冷控制的几种方法进行了系统总结和简要分析更多还原

【Abstract】 Metallurgical Principles on continuous cast slab cooling are described and the aim of optimization of secondary cooling pattern,inverse calculation method of slab surface temperature and functional optimization of metallurgical coolingprinciple are related in detail taking billet and slab in continuous cast as an example,meanwhile the several methods of secondary cooling control in continuous cast are systematically summarised and briefly analysed.更多还原
