Abstract
The process feeds a mixture of scrap metal, quartzite, carbonaceous material and wood chips to a submerged arc furnace to make a base iron suitable for iron foundry purposes. The mixture contains 1 to 20% quartzite, 5 to 15% carbonaceous material, 0 to 10% wood chips, all based on the weight of scrap in the mixture. By maintaining the charge in the furnace, good efficiencies are obtained.
