Abstract
Despite of the great variety of rails types used in the industry,
methods of their calibration are almost identical. However, calibration of girder rails, mainly used for tramways, in contrast to conventional rails has its own peculiarities in the formation of the girder. The paper presents the results of the computer simulation and industrial experiments that include investigations of the distribution of axial porosity and evaluation of the strain state of metal during its rolling in roughing and finishing calibers for the development and introduction of a new rolling technology of tramway girder rails. According to the results of the conducted computer simulation the industrial study of axial distribution of porosity by rolling in the rough box-caliber stand BD-1 and split rail caliber stand BD-2 was carried out. Microstructure examination was made at the templates of continuous casting block, after the second, after the seventh and ninth passes in the stands BD-1, BD-2. The results of the industrial experiment showed a good agreement with the computer simulation results
