Research on the causes analysis and control methods of line defects in the head of hundred-meter rails
Abstract
In response to the rail head line defect in the production process of hundred-meter rails, through inspection and analysis of rail tracks with line defects, theoretical calculations of rolling deformation, and on-site industrial trials, it is clarified that the rail head line defect is caused by defects such as cracks in the ingot corners, slab furnace marks, and scratches during rolling. Correspondingly, effective measures to reduce the occurrence of rail head line defects are proposed for each of the three defect causes.
