Abstract

143,243. Wennerstr÷m, K. G. Feb. 10, 1919, [Convention date]. Slag cements.-Slag is melted in an electric furnace and the required amount of lime or limestone placed on the surface of the molten slag and melted by the heat imparted by the slag. Free lime is thus kept out of contact with the carbon electrodes and the formation of carbides prevented.
