Electricity's contribution to the steel industry

A brief outline of the processes involved in the production of steel is followed by a discussion of the characteristics of the various rolling mills and the types of motors used to drive them. Considerations affecting the choice of frequency are also discussed. The author believes that the greatest contribution of electricity to the steel industry is the providing of a means for economically using the waste gases from blast furnaces. He points out the importance, as a conservation measure, of the utilization of blast furnace gas and other sources of by-product power.
