Abstract
This paper examines the influence of the speed and intensity of the cooling conveyor STELMOR on the final structure of the material. Steel grade 32CrB4 was processed at Continuous rolling mill KDT in TŽ a.s. In this paper has been described why it was necessary to replace the old method for the new method and their basic differences. During that examination were also used the means of device plastometer GLEEBLE for a better view of the influence of cooling rate on the resulting structure, using the decay ARA diagram.
