Abstract

In the past the research and development of new materials for hot mill rolls was mostly done by trials. Such trials are expensive and difficult to transform from small size to the big size of a solid roll. Computation is the cheaper way to get ideas processed and can be varied in different directions. The main part before simulation is the generation of the needed basic data of the specific materials. Some data is already well known and can be bought from databases; others have to be done specifically for our materials. The evaluation of such results has to be done still with solid trials, but the number of trials can be reduced. The advanced techniques of finite element calculation offer a wide range of possibilities to get answers about alloys, solidification, casting parameters and their influence. The possibility to calculate a heat treatment cycle and to get an answer about the internal stress modification during the cycle is a great help to understand the principle of transformation. Examples of different calculations in various fields will be given. The close cooperation with universities and other research institutes as well as the in-house possibilities will be presented.
