As the object of introducing selected checkpoint sectional speed heating furnace PJSC "Dnieper Metallurgical Plant", Dneprodzerzhinsk. For the choice of technology and the development of oxy-fuel heating gas-oxygen burner designs have been calculated thermodynamic parameters using oxygen from the combustion of gaseous fuels with oxygen and oxygen-enriched air. It has been shown that replacing air with oxygen at 500-900 ° C raises the temperature of the combustion gas of fuels, 3.5 times the volume decreases and the amount of combustion heat of the kiln handed down at the same temperature at the exit and almost two times increase the emissivity of the torch. These properties oxy-fuel flames form the basis for a wide range of oxygen in the combustion process in the heating furnaces and devices. Calculations speed heating of steel bars with a diameter of 80 mm and 40.60 with the use of oxy-fuel burners in one area pyatizonnoy continuous furnace ball-rolling mill. It is shown that the oxygen enriched air heating mode switches the mode to "thin" body to the transition between the "thin" and "massive" at concentrations of oxygen in the oxygen-air mixture of 35-40%, which corresponds to values of Bio> 0.5. This conclusion is taken into account in determining the thermal regime of the heating mode selection in the areas of thermal equalization. The technical project of reconstruction of furnace burners kislorodoprovodom binding. The project was adopted for implementation, ordered equipment Product Description popup.authors Антощук Тарас Олександрович Зайвий Олександр миколайович Лисенко Анатолій Анатолійович Марцевий Євген Павлович Молодоженя Софія Анатоліївна П'яних Костянтин Євгенович П'яних Костянтин Костянтинович Петренко Володимир Микитович popup.nrat_date 2020-04-02 Close
