Increase of metal properties in process of it treatment by heating in furnaces with gas dynamical separation of smelting chamber
Model of gas furnace with gas dynamical separation of smelting chamber is proposed. Use of model was allowed to increase metal properties at the expence of it treatment by heating at influence on it products of gas combustion. Model reflectes physical picture of gas movement in smelting chamber at it separation by second air stream directed from lateral walls to center on furnace length. By means of model can analytically establish correlations of stream movement rates of incomplete combustion products directed in metal treatment zone and second air stream directed in incomplete combustion product stream lifting up. Model allows also select definite angle of nozzle mounting for feeding of second air that ensures minimum dilution of gas layer and stability of gas composition over metal.
