Abstract
To explore the smelting process of condensing submerged arc furnace,a three-dimensional electric-magnetic-thermal-mechanical coupling simulation model of condensing submerged arc furnace is established in this paper.The coupling mechanism between multiple physical fields in a condensing submerged arc furnace is numerically simulated.In addition,the influence of different electrode insertion depths on the furnace temperature,stress and strain is analyzed.The results show that the current in the furnace flows in and out in four paths.The magnetic induction intensity around the arc is larger,and the maximum value is distributed at the edge of the arc.The maximum joule heat value is distributed around the arc area As the electrode insertion depth increases from 1.8 m to 2.2 m,the temperature of the magnesia brick at the furnace bottom gradually increases,and the stress and strain of the furnace body also increase accordingly.The circumferential tensile stress on the outer surface of the furnace shell is greater than the axial tensile stress.
