Abstract
A three-dimensional (3D) finite element heat transfer model was established to predict temperature in the mould of thin slab continuous casters. The effects of copper plate thickness and scale deposition thickness on temperature were analyzed in detail. The results showed that during casting, the maximum temperatures, about 448°C for the wide hot face and 408°C for the narrow hot face, were found locating in about 60 mm below the meniscus. With copper plate thickness reduced by 4 mm, the maximum temperature decreases by about 50°C for the wide face and 40°C for the narrow face. However, decreasing the copper plate thickness has little effect on cold face (the root of water channel) temperature. The copper plate temperature increases when water slot surface is covered with scale deposits.
