Abstract
ABSTRACT The casting parameters and behaviour of 61 sticker breakouts were analysed during the continuous casting of the conventional slab. The difference of sticker breakouts between the conventional slabs and wide and heavy slabs was also studied. The results show that the high casting speed or change of casting speed is the main reason. The mould level of the conventional slab is small and not the reason for sticker breakouts, which is different from the causes of wide and heavy slab. In terms of propagation behaviour, there are 14 cases out of 61 sticker breakouts occurred only around one column of thermocouples. The vertical velocity is in the range of 0.3∼2.4 m·min−1, and the horizontal velocity is in the range of 1.0∼9.0 m·min−1. The vertical velocities of the three sticker breakouts are higher than their casting speeds, which is different from the wide and heavy slab.
期刊介绍：
Ironmaking & Steelmaking: Processes, Products and Applications monitors international technological advances in the industry with a strong element of engineering and product related material. First class refereed papers from the international iron and steel community cover all stages of the process, from ironmaking and its attendant technologies, through casting and steelmaking, to rolling, forming and delivery of the product, including monitoring, quality assurance and environmental issues. The journal also carries research profiles, features on technological and industry developments and expert reviews on major conferences.
