FEATURES OF PLATE ROLLING ON 3 HIGH LAUTH MILL

Investigations have been carried out on a 2150 Lauth mill to determine features of plate rolling. The dependence of the plate reduction schedule on the temperature regime of rolling and transverse thickness variation of the stock is discussed. The speed conditions of deformation prevent dynamic and metadynamic recrystallisation, resulting in the formation of a homogeneous structure at the stage of dynamic recovery and dynamic polygonisation and a corresponding improvement in the properties of the metal. The mill motor has substantial reserves, which could be used to improve plate quality by rolling in the two phase alpha + gamma region at reduced temperatures.
