Excerpt from Transactions of the American Institute of Chemical Engineering, Vol. 1 of 12 The Snyder or any other direct arc furnace is applicable only to true bronzes or other alloys low in zinc, 5% zinc being the probable limit. It is entirely impractical for use on alloys high in zinc. The only installation used for copper alloys is used on leaded bearing bronze, the new lead being added in the ladle. Much lead is volatilized from the scrap in the charge, and much fume results, giving bad working conditions. The installation of Snyder furnaces has a very poor power factor, though this is not necessary in a direct arc furnace.
