The influence of water flow rate on the surface cleanliness of slabs was investigated through the hook reveal and inclusion detection. The numerical simulation was performed to calculate the shell thickness with different water flow rate. With the decrease of the water flow rate from 99 to 88 L/s, the hook depth reduced at most of positions, and the number of > 5 μm inclusions decreased. The contour was calculated to provide guidance for adjustment of the water flow rate.
Key words: water flow rate / hooks / inclusions / ultra low carbon / continuous casting slabs
