This proposal proposes a physically based quantitative model that depicts realistically the contact process and predicts roll wear which accounts for carbides and oxide in practical rolling conditions. The wear mechanism of HSS roll will be investigated through an integrated approach involving new experimental set-ups, advanced computational modelling and material characterisation techniques. The proposed model also can potentially be applied to the abrasive wear of multiphase composite materials and HSS cutting tools in machining. It can make a remarkable contribution to the contact mechanic, reduce costs and improve strip quality such as strip thickness and shape in hot rolling.
