Abstract :
IF ALL THE APPLICATIONS of electricity were listed, it would be found that this servant of man is used more extensively and in a greater variety of applications in the manufacture of steel than in any other industry. From the tiny photoelectric cell to the giant slow-speed reversing rolling-mill motor delivering torques of 2,000,000 pounds at one-foot radius, the application of electric power with its ease of control in the manipulation of steel is amazing as well as fascinating to anyone.
