Abstract

Abstract

The demand for high value-added steel grades is relatively low, and more than one steel grade needs to be produced per casting sequence. Industrial tests of the steel grade transition carried out by domestic enterprises is sorted out in this paper. The application of water model experiment and numerical simulation in the steel grade transition is described. And the influence of tundish level, non-isothermal casting, tundish furniture, mold fluid domain structure, casting speed and electromagnetic braking on the length of transition billets is mainly summarized. After evaluating the four main mathematical models for judging the steel grade transition, the idea of formulating the specification for the steel grade transition and studying the new model for the steel grade transition is finally put forward. It can be concluded that the steel grade transition realizes the efficient production of new steel grades, reduces the production cost of enterprises. combining the disciplines of artificial intelligence and metallurgy practice can provide a new development direction for metallurgical engineering.
