The article presents the main results of CAE-modeling of temperature processes occurring in the nozzle of a scrap cutter when cutting scrap with a thickness of more than 800 mm. The temperature distribution in the nozzle body is shown when it is cooled by a jet of cutting oxygen. The features of creating computational models of heat transfer from the scrap surface to the working end of the nozzle are considered, and conjugate calculations of temperature fields in the nozzle body during cold purging with a jet of cutting oxygen of the central channel are carried out.
