Distinctive aspects of the physical metallurgy of warm rolling

Warm, or ferritic, rolling is gaining in popularity amongst steel makers as a means of cutting the cost of steel production and opening up the window of hot band properties. The current work presents an overview of some of the more unique, but important, metallurgical aspects of the process. These have been highlighted in a number of laboratory studies that have been conducted over the last decade or so and as yet appear not to have been drawn together in a single article. Certain aspects of the industrial practice of warm rolling are also addressed. But it must be noted that these are somewhat sparse in the literature, presumably due to its status as an emerging, as opposed to widely practised, technology.
