Abstract In this study, the parameters of 44 sticker breakout samples were analysed. The research mainly focused on the steel grades and slab thickness of stickers. Other processing parameters, such as slab width, casting speed, mould fluctuation, heat flux and operation, were also discussed. The results show that the number of stickers of low carbon steel and low alloy steel was 16 and 28, respectively. The stickers of low carbon steel were less than those of low alloy steel regardless of the thickness and width. The ratio of stickers per 1,000 casting heats of 220, 260 and 320 mm thickness slabs was 2.5, 0.5 and 0.6, respectively. The higher casting speed of 220 mm thickness slabs made the casting status unsteady and caused more stickers. From the perspective of width, the stickers were gradually increased along with the increase in width due to the worse mould slag. This study provides a foundation to reduce slab stickers and is helpful for a more efficient technology of continuous casting.

连铸工艺参数对板坯粘着性的影响

摘要 本研究对44个贴纸突破样品的参数进行了分析。研究主要集中在贴纸的钢种和板坯厚度上。还讨论了其他加工参数，如板坯宽度、铸造速度、结晶器波动、热通量和操作。结果表明，低碳钢和低合金钢的贴纸数量分别为16和28。无论厚度和宽度，低碳钢的贴纸都小于低合金钢的贴纸。220、260 和 320 毫米厚板坯的每 1,000 次铸造炉次的粘连比率分别为 2.5、0.5 和 0.6。220 毫米厚板坯的更高铸造速度使铸造状态不稳定并导致更多的粘连。从宽度上看，由于模渣变差，贴纸随着宽度的增加而逐渐增加。该研究为减少板坯粘连提供了基础，有助于更高效的连铸技术。
