| Abstract Scope |
The integration of the process metallurgical effects upon the physical metallurgy of the heated slab or billet in actual practice is rarely reported. This relationship between the reheat furnace operation, condition and efficiency closely relates to the propensity for the initiation of abnormal austenite grain growth prior to the hot rolling step of the production process. Inhomogeneous furnace heating of slabs and billets results in variations in the prior austenite grain size and hence, variability in the final grain size and mechanical properties. Often laboratory studies attempt to simulate actual furnace conditions and the influence of different microalloys on the austenite pinning effect, but the technical transfer of these laboratory results to the mill is quite difficult and often inaccurate due to simulation incongruence with the actual furnace operation. Key reheat furnace process parameters are reviewed which directly influence the austenite grain size during the reheat process. |
