Characterization of hot rolled scales-root cause identification …
Hot rolled steel strips are produced by rolling of steel slabs of 210 mm thickness at 1150–1200 °C through roughing and finishing mills of a hot strip mill to a thickness of 1.6–6 mm.During hot rolling, some adherent oxides, known as scales, is formed on the strip surface in the reheating furnace prior to hot rolling due to high …

The effect of scaling on interfacial friction in hot rolling of …
Hot oxidation and hot rolling experiments were undertaken in order to investigate scale formation and its effect on the frictional conditions in the hot flat-rolling of steels. The effect of scale thickness on the coefficient of friction in the hot rolling of a low carbon and a microalloyed steels is examined. A model of scale growth is presented, …

Strip shape modeling and its setup strategy in hot strip
Shape setup model (SSM) plays a critical role to achieve satisfactory precision of strip shape in hot strip mill process (HSMP). However, for the design of shape model, the lack of systematic shape theory restricts the high accuracy of strip shape. In this paper, the procedure of SSM will be generally introduced and practically demonstrated …
