Abstract
1342529 Casting metals WESTINGHOUSE ELECTRIC CORP 19 April 1971 [5 Feb 1970] 20371/71 Heading B3F [Also in Division H5] An electric arc furnace has a rotatable electrode 137 mounted above the surface 151 of the melt 153 in the mould 152, magnetic means 136 causing the deflection and focusing of the arc 157 and the stirring of the melt. The electromagnet 136 is supplied with cooling fluid and an electrical supply via conduits 226, 134 and 227, 135 respectively. The electrode 137 is also supplied with cooling fluid via conduits 171, 172, is rotated by means of motor 221 and is connected to its electrical supply via lead 159 and rheostat 223. In Figs. 1, 2 (not shown) the electromagnet is located respectively around the mould and around the furnace wall and the motor may have a reversing control. In Fig. 4A (not shown) the electrode is hollow and is supplied at its tip with gas or other material. Each of the embodiments is shown having a vacuum pump connected to the furnace housing and a retractable mould floor.
