摘要：A sticker breakout is a significant occurrence which not only disturbs steady state casting but also reduces plant productivity and efficiency. Optimising the casting parameters and increasing the accuracy rate of breakout prediction systems are two effective measures for reducing breakouts. In the present paper, plant data were collected and the influence of casting parameters such as slab dimension, casting speed and mould level on sticker breakouts were analysed, especially the effect of heat flux. In addition, sticker propagation behaviour characteristics, including vertical velocity, horizontal velocity and propagation angle, were investigated by measuring the temperature of the mould copper plates. These results provide a reference for optimising the casting parameters and enhancing the accuracy of breakout prevention systems.
