Abstract:The cast-roll process (CRP) is widely used in ACR (air conditioning and refrigeration copper. tubes), which can increase the yield and greatly reduce the cost However, there are few studies of CuNi10Fe1Mn alloy tubes on CRP. The purpose of this paper is to provide the based datum for study of CuNi10Fe1Mn alloy tubes. The paper explored the three major processes of horizontal continuous casting, planetary rolling and drawing, and studied the macrostructure, microstructure, mechanical properties and activation energy for deformation of planetary rolling. The results demonstrate that: the CuNi10Fe1Mn alloy tubes have good properties, so it is feasible to be produced by CRP; CRP can refine grains, which is one of the several strengthening methodologies developed to restrict the dislocation motion; the power of planetary rolling mill may be increased approximately 2.0-3.0 times than that of C12200; the rolled tubes of CuNi10Fe1Mn alloy still could be drawn by three passes deformation without an intermediate annealing.
