Abstract
The article discusses problems related to the influence of rolling processes on the process of closing of internal discontinuities in continuous castings during rolling in two types of shape grooves. Numerical modelling of the process of rolling 160 x 160 mm continuous C45 steel billets using the Forge 2008® software program. Variations in deformed strip temperature, as well as in the shape of holes simulating material discontinuities were examined.
