Comparison of Heat Transfer Power of the Cooling Panel with Square Cross Section and Circular Cross Section in Electric Arc Furnaces Steelmaking by the use of Computational Fluid Dynamics

Abstract

Steel pipes with circular cross-sections are usually used in cooling panels of electric arc furnaces. In the present study pipes with square cross-sections under equivalent conditions were used to obtain more information on the possibility of increasing the heat transfer and cooling efficiency. The results showed increased efficiency of the square pipe compared to the circular cross-section pipes. This increase led to an increase in the cooling power and life expectancy under similar conditions. The fluid flow field and heat transfer were obtained using simulation. A comparison of the heat transfer and the energy of the circular and square cross-sections showed that the square cross-sections had a higher rate of heat transfer and work efficiency.
