Abstract

In order to save energy, hot rolling of near net shape cast strip has to be performed in-line. For this, special conditions which are different from those in conventional casting must be taken into account. In-line rolling in the first heat that is rolling without cooling down and reheating leads to a sequence of phase transformations different from conventional hot rolling and, therefore, gives different conditions for the formation of the internal structure. These special conditions during in-line rolling lead to problems which were subject of this project. A series of experiments were performed to investigate to which extent the cross-sectional profile of a strip can be changed by conventional rolling. The metallurgical and mechanical properties of a strip with an as-cast thickness of 10mm and hot rolled (after cooling down to room temperature and reheating) with different reduction ratios were examined. Finally, the influence of hot rolling in the first heat on the austenite grain size investigated. Preliminary trials were performed to develop and to test metallographical preparation and evaluation technique.
