In this paper, the formulas of heat transfer coefficients are gained by studying the characteristics of the heat transfer between spraying water of nozzles and the surface of billet. Three kinds of water nozzles are used, which include flat nozzle, ellipse nozzle and cone nozzle. Also, this paper analyzes the varying patterns for heat transfer coefficients as well as heat densities of three kinds of nozzles and discusses the factors affecting both of them.

本文对三种喷嘴(扁喷嘴、椭圆型喷嘴、圆锥型喷嘴)的喷淋水与铸坯表面间的传热特性进行了实验研究,获得了三种喷嘴的喷淋水与铸坯表面传热的传热系数计算式,分析了传热系数和热流密度的变化规律及其影响因素。

Features of secondary cooling nozzle for extra low head slab concaster at Nanjing Iron and Steel have been tested, and it showed that water flow of flat nozzle was distributed uniformly, but the water flow of round nozzle was distributed non- uniformly, easily to produce concave at side of slab and crack at delta zone. Based on 1 000 mm×180 mm concasting slab cooling process simulated by secondary simulation software, the developed process model is obtained that the all flat nozzle are used...

Features of secondary cooling nozzle for extra low head slab concaster at Nanjing Iron and Steel have been tested, and it showed that water flow of flat nozzle was distributed uniformly, but the water flow of round nozzle was distributed non- uniformly, easily to produce concave at side of slab and crack at delta zone. Based on 1 000 mm×180 mm concasting slab cooling process simulated by secondary simulation software, the developed process model is obtained that the all flat nozzle are used at side of slab, and the distance between nozzle at surface of slab decrease to 180~200 mm from original 225~300 mm. Application results showed that quality products rate of concasting slab increased to 92.22% from 86.32%.

对南钢超低头板坯连铸机使用的二冷喷嘴性能测试表明 ,扁平喷嘴喷射水流分布均匀 ,而圆形喷嘴喷射水流分布不均匀 ,易造成板坯侧面凹陷和三角区裂纹。根据二冷仿真软件模拟 10 0 0mm× 180mm板坯冷却过程 ,得出改进工艺模型 :在板坯侧面全部采用扁平喷嘴 ,并将板坯正面喷嘴间距由 2 2 5~ 30 0mm改为180~ 2 0 0mm。应用结果表明 ,生产板坯的优质品率由 86 32 %增至 92 2 2 %。
