摘要
The article is devoted to the numerical modelling of electrovortex and convection flows in DC electric arc furnace with the cooling bottom electrode. The shear stress on the fettle area are offered as criteria for the estimation of vortex flows influence on the increased wearing of fettle. It is shown that cooling down the bottom electrode to the melting metal temperature leads to decrease of shear stress on the fettle area by 15 %.
