The nation during this period was producing 40 million tons of pig iron a year with a concomitant output of 20 million tons of slag. At the same time, another problem the companies were facing, particularly during the latter part of 1917, was the car shortages for hauling slag due to the heavy demands for freight shipments to serve the war effort.

Titanium slag. You can derive an extra benefit from titanium slag furnaces because they produce TiO 2 rich slag and pig iron as valuable byproducts. The ilmenite ore can be processed in either DC or AC furnaces. It's a special advantage of DC furnaces that they can smelt ore fines without pretreatment.
