Krupp/Platzer reciprocating mill rolling in production conditions

Abstract

The Krupp/Platzer reciprocating mill is a new cold-rolling mill which is able to roll non-ferrous metal strips with reductions of up to 90% in one pass without any annealing. In comparison with the results of conventional rolling mills the values of tensile strength and yield point of the reciprocating-mill strips are lower. No differences in hardness of the strip surface and microstructure were found in conventional-rolled and reciprocating-rolled strips. Rolling load and torque show a characteristic profile. Structure and hardness of the wedges at the end of strips present the entire deforming process of this new rolling method.
