Abstract

The invention discloses a simulation device for solidification of molten steel in a continuous casting crystallizer under the function of electric pulses. By simulating application of the electric pulses in the solidification process of the molten steel in the continuous casting crystallizer, measuring and calculating surface temperature and heat flow change curves of the crystallizer under different electric pulse conditions, obtaining solidification blank shells and slag films under different conditions and studying influences of different electric pulse conditions on the heat transfer behavior between the molten steel and the crystallizer, the blank solidification structure, the blank shell form and the like, the study of the solidification behavior of the molten steel in the continuouscasting crystallizer under the function of the electric pulses is realized, so that the electric pulse conditions are further optimized, and the continuous casting process is conducted smoothly and effectively. The operation is simple, experiment cost is low, and the simulation device is an ideal simulation and study device for the solidification behavior of the molten steel in the continuous casting crystallizer under the function of the electric pulses in a laboratory. The simulation device has the advantages of being simple, convenient and controllable in experiment operation, short in flow, high in efficiency, low in experiment cost, and the like.

Description

Technical field [0001] The invention belongs to the technical field of steel continuous casting, in particular to a device for simulating molten steel solidification in a continuous casting mold under the action of electric pulses. Background technique [0002] The molten steel in the continuous casting mold undergoes complex, high temperature, multi-phase, and instantaneous physical and chemical changes during the continuous casting process. The solidification behavior of the molten steel in the continuous casting mold can breed problems such as the quality of the cast slab. Therefore, the continuous casting mold is studied The solidification behavior of internal molten steel is of great significance, especially the effect of electric pulse on the solidification behavior of molten steel. Electric pulse, as an instantaneous, high-density energy form of external field, has been studied in different professions and fields, and has achieved good scientific research benefits. Due to...
