• 論文の詳細を見る

• The formation of clogging materials in an immersed nozzle during the continuous casting of Ti-stabilized stainless steel was studied by plant and laboratory experiments. The major materials deposited were globular Ti oxide as curved chain and Al2O3 as large, black agglomerates. On the contrary, TiN and Al2O3 were observed in the steel in the tundish, and Ti oxide was scarcely found. The curved chain of globular Ti oxide could only have been formed by reoxidation after nitrogen absorption in the laboratory experiments. The formation mechanism for Ti oxide from TiN decomposition is proposed for the clogging behaviour of Ti-stabilized stainless steel.
