介绍了连铸二次冷却过程中喷淋水与高温铸坯表面接触时的换热特点,以及影响连铸二冷过程喷淋水与铸坯传热的因素,进而通过分析连铸二冷喷嘴的冷、热态性能,探讨了连铸二冷喷嘴类型及布置方式对铸坯质量的影响。
The heat transfer characteristics of spray water and the surface of high temperature slab during the secondary cooling process of continuous casting are introduced as well as the factors that affect the heat transfer of spray water and slab during the secondary cooling process of continuous casting. The cold and hot performance of castings, the effects of the type and arrangement of secondary continuous cooling nozzles on slab quality were discussed.
