INCREASING TOOL LIFE OF ROLLERS FOR ROLL FORMING OF TUBES
Journal Title: Tribologia - Year 2014, Vol 258, Issue 6
Abstract
Industries engaged in roll forming of tubes apply different methodologies and innovating technologies in order to perform this task, but tubes with welded seams are more profitable. The basic tooling used to roll-form tubes, or rolls, are usually made of a tool steel with a high Chromium content, namely, D2 steel. However, in order to produce higher quality tubes of high-strength steels, higher mechanical properties than those shown by D2 steel are required. As a consequence, new technologies, designs, materials, and heat treatments have emerged so the new requirements are met. This has a direct impact on the costs incurred and the productivity of metalmechanic industries. In this project, various cold work steels were analysed and compared with D2 steel, in order to improve the tool life of rolls for roll forming of tubes. Tribological testing was done with a T-05 block-on-ring setup with testing conditions similar to those in real life. Charpy testing was done in order to obtain impact toughness. The obtained results are of great importance, because they may result on significant cost reductions.
