Modelling floorplate pattern generation

Abstract

The rolling of floorplate is considered as a combined process of reduction and extrusion. The reduction from the incoming plate thickness to the outgoing plate thickness is combined with extrusion of material into grooves cut into the rolls to produce a raised pattern on one side of the base plate. The average rolling pressure is predicted and used to determine an extrusion ratio and hence a pattern height. The theoretical model is based upon mass flow conservation, a simplified form of rolling pressure calculation, and a linear fit to known relationships between extrusion ratios and pressures. Comparisons with results obtained from dimension measurements of rolled floorplate are presented.
