摘要

Research results for the production of strips from a platinum‒rhodium alloy for the manufacture of spinneret feeders are presented. Using the author’s software, an analysis of the process of rolling strips of the investigated alloy with a thickness of 1 mm from a forged workpiece with a thickness of 28 mm, which is currently used in industrial conditions, was carried out. The number of rolling passes and the number of annealing steps decreased. Experiments for the process of cold sheet rolling of strips from the platinum‒rhodium alloy were carried out. The proposed compression mode was tested under industrial conditions, and it was found that for the studied process of cold sheet rolling of a platinum‒rhodium alloy, it is possible to increase the unit degree of deformation to 0.3–0.4 mm, which leads to a decrease in the fractional deformation, a decrease in the number of anneals and passes in the absence of strip destruction.
