The report considers development of a methodology for heating slabs with a system of flat jets interacting with the metal surface. Heating technology must meet modern requirements for uniformity of heating, energy efficiency and optimal heating rate. Multivariate calculations were performed with changes in location, number of devices and distance from the nozzle exit to the heating surface. In this work, using the ANSYS Fluent program, an instrumental system was used through the mechanism of blowing devices that form 8 and 9 jets. In the developed methodology, it is proposed to use heated nitrogen, which simultaneously performs two functions: heat engineering and technological (as a protective atmosphere).
