The hot state chalacteristics of the secondary cooling nozzles used for Pangang slab Continuous Caster were systematically measured with heat transfer coefficient measurement apparatus. The relations between heat transfer coefficient and surface temperature of strand under different water flow rate and air flow rate were obtained. The research results provide a basis for selecting nozzles and optimizing secondary cooling system.

利用传热系数测试装置,系统地对攀钢板坯连铸机上使用的喷嘴进行了热态性能的测定,获得了这些喷嘴在不同水量和气量下传热系数随铸坯表面温度的变化关系。测试结果为喷嘴的选择以及进一步研究二冷传热机理和设计合理的二冷工艺制度打下了基础。

Mechanism for the billet breaking off is analyzed and it is found that serious wearing of the mould, fluctuation of tundish temperature and abnormal functioning of the secondary cooling nozzle are main causes and to prevent the accident counter measures have been taken and thereby the rejected products greatly reduced.

The kind of CC secondary cooling nozzle and its advantages and faults, the effect of spray on casting blank and questions of nozzle head material in maintenance are discussed and the study of cooling property for the introduced and native nozzle for bloom and round billet is made. The results show that water intensity of the native-made nozzle distributes evenly around center and has benefit on cross even cooling. But for the five tested nozzle on spraying angle, four kinds can meet the requirement of the native ferrous metallurgy standard, only D40197—1 nozzle is over +4 degree on high pressure test. A small amount of native-made nozzle flow's relative error is 1%~10%, which has effect on water distribution during CC production.

本文主要论述连铸二冷喷嘴的类型、喷雾方法对铸坯冷却的影响 ,各类喷嘴冷却的优缺点 ,以及环型喷嘴嘴头的材质在检修中出现的问题。对包钢引进大方坯和大圆坯的汽雾喷嘴和国产喷嘴的冷态特性进行测试研究 ,测试结果表明 ,国产喷嘴的水流密度分布在中心的左右 ,分布均匀 ,对大方坯和大圆坯的横向均匀降温有益 ,但是国产喷嘴的喷射角度在测试的五种喷嘴中 ,有四种喷嘴符合国家黑色冶金对喷嘴喷射角度的要求 ,只有D40 197- 1喷嘴在高压测试时超国家要求的 +4° ,有少量国产喷嘴在同压力条件下的流量误差在 1%~ 10 %之间
