Excerpt from Journal of the Cleveland Engineering Society, Vol. 3: September, 1910 Resistance furnaces have been designed for the manufacture of steel, but have not met with much success. Fig. 3 illustrates such a furnace, which is manufactured in France, and is known as the Ginn furnace. The current enters through water cooled elec trodes BB and traverses the long hearth aa. A charge of molten metal is poured into the hearth through an opening in the ioof' at H. The current is then turned on and serves to heat the metal and cause the reactions necessary for its transformation into steel. When the steel is finished. It is tapped off through the spouts shown at K. The hearth is mounted on a car so that it can be drawn out from under the furnace roof for repairs. The difficulty of main taining the long channel in the hearth in preper condition and preventing the current from short circuiting across the channels makes this furnace very difficult and expensive to operate. It is also difficult to hold the metal uniform in all parts of the hearth These are the essential features. Which handicap its successful introduction.
