Abstract:Mold flux is an important functional material, which plays an important role in ensuring the smooth running of continuous casting process and improving the quality of the slab. However, during continuous casting, mold flux is easy to adhere to the inner wall of the mold to form a slag rim. The oversized slag rim will weaken the function of controlling heat transfer and lubrication of the slag, which will easily increase the surface defects of the slab and even cause breakouts.The research results of the formation and growth mechanism of the slag rim at home and abroad are reviewed from the macroscopic and microscopic aspects, and the adhesion condition of the slag rim on the mold wall is analyzed, and the factors affecting the formation and growth of the slag rim are summarized. Meanwhile,it points out the deficiency of the existing research and provides reference for the future work.
