Engineering cases are in the ascendant in the metallurgical engineering. In the face of the boring traditional teaching methods and the disjunction with the actual production, the topic selection and course planning of the project case are put forward in this paper. By enriching the case resource base, increasing the proportion of double-qualified teacher team, building a teaching platform combining the virtual situation with the actual situation, carrying out online and offline interactive teaching, these can ensure students' learning initiative and improve their interest in learning the core course "Iron and Steel Metallurgy Ⅱ".
