Purpose and goal
The aim of the project was to increase the quality of centrifugal-cast rolls. goals: 1- Log temperatures in the foundry and develop a program to visualise them 2- Develop a model for the cooling of the core material and the temperature evolution during solidification and cooling of the shell 3- Develop a control module to suggest actions to the casting leader in order to increase the chances to obtain the target temperatures at the time of the casting 1- logging and program are operational 2- the models need to be finalised 3- the control module requires data from the simulations
Results and expected effects
The cooling in the ladle can be predicted using a physical model. The calibration was done in a limited number of cases and further calibrations need to be performed for different geometries and for the melting of pig iron in the melt. The lack of material data during solidification make it difficult to develop a model for the solidification and cooling of the sleeve in the chill. For this reason an attempt to build an empirical model was done. This is to be continued based on a larger number of casting data.
Approach and implementation
Logging temperature data continuously will provide more data, which will be used to calibrate the models. Further work will be based on these temperature records in order to develop the empirical model for the evolution of temperature in the sleeve and the cooling in the ladle.
