| Investigation of Heat Transfer in the Spray Cooling of Continuous Casting |
| |
| 摘 要： | The heat transfer coefficient between spray water droplets and hot surface is measured in the laboratory. The effect of spray water flow rate, water pressure, spray distance of nozzle from the surface of strand, spray water temperature on the heat transfer is made a detail studied. And meanwhile, the effect of the strand surface FeO scale on the heat transfer is also investigated. According to the experimental results, the influence of above factors on the heat transfer coefficient has been discussed and a experience formula between the heat transfer coefficient and spray water flow rate is given out.
