Abstract

Due to the improvement of efficiency of power equipment (heat exchanger), it has been required to change the arrangement of exchanger tube bodies through the minimization of exchanger tubes bending radius. It was necessary to optimize process parameters and functional parts of forming tool to achieve the required parameters of tube bending. On the bending rail, which is one of the main parts of forming tool was used a newly developed type of cast iron with especially suitable characteristics minimizing a coefficient of friction during forming processes. In this paper we present the obtained results and material features in strain area of exc hanger tubes.

Keywords: bending of tubes, bending radius, ovality, strain, abrasion resistance cast iron
