Thus, it is seen that fluid flow in continuous casting plays an important role in determining the quality of cast slab. Realizing this several researchers have attempted to study fluid flow in various in various stages of the continuous casting process. Study of fluid flow in continuous casting is made difficult by the temperature of the process and the opacity of the molten metal which prevents direct visual observation of molten metal flow in the ladle, tundish and the mold. To overcome these difficulties researchers have used the techniques of water modeling [8-12] and mathematical modeling [13-15]. In water modeling, the flow of molten steel is simulated by the flow of water at room temperature. In order to obtain direct quantitative information …show more content…

In this work attention was devoted to the literature available for the complete understanding of the continuous casting steel making process. Also, the behavior of melt flow and the effect of various parameters on mixing phenomenon that occurs during grade change process in sequential casting of different grades have been discussed. The aim of present work is to analyze mixing in the tundish during the grade change operation in continuous casting steel making process. The effects of flow modifiers on the quantity of mixed grade produced due to mixing in the tundish have been analyzed with the help of simulation. An experimental set up has been fabricated for water modeling of steel flow characteristics within the …show more content…

In a continuous casting process, different grades of steel have to be cast in a sequence in a sequence, preferably without stopping the caster. During this process, due to continuous casting operation of the tundish and the mold, a certain amount of intermixing takes place of two grades being cast in sequence, this intermixing may result in the casting of a certain amount of steel whose composition lies outside specification of the old or new grade. In general this steel has to be downgraded. The extent of mixing between the grades is determined by the fluid flow patterns within the tundish and mold. It is desirable to reduce the amount of intermixed grade cast so as to minimize wastage of energy, material and manpower and to improve the economics of the steelmaking operation. Intermixing can be minimized by varying casting parameters. To do this effectively, a detailed knowledge of effect of various casting parameters on the fluid flow and mixing in tundish and the mold is required
