【Abstract】 On the basic of a successful model of LD converter and taking electromagnetic force into consideration, a mathematic model is developed to calculate the electromagnetic and temperature field of a 30t DC are furnace with bottom electrodes, and the electromagnetic field, temperature distribution, recirculating flow rate, circulation period and mixing time are obtained. The results give important criteria to the design and operational optimization of DC are furnaces.更多还原
