对某小方坯连铸机高效化改造中 ,二次冷却区所采用的三种喷嘴的冷态及热态性能进行了研究 ,获得了相应的性能参数。还对高效连铸二次冷却对喷嘴性能的要求进行了评价 ,提出了有效喷淋系数的概念。
The cold and hot performance of the three kinds of nozzles used in the secondary cooling zone were studied in the high efficiency retrofit of a billet caster, and the corresponding performance parameters were obtained. The requirements of high performance continuous casting secondary cooling nozzle performance were also evaluated, and the concept of effective spray coefficient was put forward.
