Calculation of the Combined Heat Transfer Coefficient of Hot-face on Cast Iron Cooling Stave Based on Thermal Test
Cooling effects of the cast iron cooling stave were tested with a specially designed experimental furnace under the conditions of different temperatures of 800 °C, 900 °C, 1,000 °C and 1,100 °C as well as different cooling water velocities of 0.5 m·s–1, 1.0 m·s–1, 1.5 m·s–1 and 2.0 m·s–1.

| description | Cooling effects of the cast iron cooling stave were tested with a specially designed experimental furnace under the conditions of different temperatures of 800 °C, 900 °C, 1,000 °C and 1,100 °C as well as different cooling water velocities of 0.5 m·s–1, 1.0 m·s–1, 1.5 m·s–1 and 2.0 m·s–1. Furthermore, the combined heat transfer coefficient of hot-face on cast iron cooling stave (αh−i) was calculated by heat transfer theory based on the thermal test. The calculated αh−i was then applied in temperature field simulation of cooling stave and the simulation results were compared with the experimental data. The calculation of αh−i indicates that αh−i increases rapidly as the furnace temperature increases while it increases a little as the water velocity increases. The comparison of the simulation results with the experimental data shows that the simulation results fit well with the experiment data under different furnace temperatures. |
