| Abstract: | 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. |
