White-hot steel pours like water from a 35-ton electric furnace, Allegheny Ludlum Steel[e] Corp., Brackenridge, Pennsylvania The finest quality steels and alloys are produced in these furnaces, which allow much greater control of temperature than other conversion furnaces. The proportion of electric furnace steel is rising steadily, even though this process is the most expensive. "The furnace is tilted for the pouring." The flying sparks indicate the fluidity of the steel

Steel manufacture, Allegheny-Ludlum. White-hot steel pours like water from a thirty-five ton electric furnace. The finest quality steels and alloys are produced in these furnaces, which allow much greater control of temperature than other conversion furnaces. The proportion of electric furnace steel is rising steadily, even though this process is the most expensive. The furnace is tiled for the pourings. The flying sparks indicate the fluidity of the steel
