Creation of model sets to predict technological parameters/ thermal processes to enhance tqm system.

Creation of new systems as original tools to enhance
existing and develop new techniques/products in metallurgy
with higher service properties at comparatively low
production costs and verification of them.

The targeted solution of this project is to create an integrated complex of models and thus give technologists a practical tool for better control of production process. This will enable the introduction of new products of higher quality at provably lower costs. The project envisages the use of original models of thermal field of continuously cast ingots developed by the solvers and models of chemical heterogeneity. During the projects to these models will also be added a model resolving thermal stress in the solidified part of the ingot with the possibility of indicating the onset of critical stresses leading to the formation of defects. Particular attention will be paid to modelling of processes in the mould, particularly in the gap, which is created during solidification between continuously cast ingot and mould walls, and which is filled with casting powder. The setting of parameters of the continuous casting process itself will be effected within the frame of the model using multi-dimensional numeric optimisation. The whole system will be further completed by a model resolving inverse role so it will be possible to make adjustments to previous models on the basis of measurement on real industrial equipment. Verification of modifications in the technology will be realised with use of the model OPTIMA, developed by the applicants, which enables acquisition, processing and evaluation of technological parameters and determination of their influence on formation of defects in continuously cast ingots and final products. Due to fact that material constants, such as thermal conductivity, specific heat capacity and density are not fully known as function of temperature in the full range of temperatures (particularly in liquid metal and in zone of solidification), it is presumed that there will be effected experimental measurement of these values for basic assortment of cast steels. We expect to obtain other material properties by parametric study. Keywords: steel, concasting, model
