Abstract
THERE has been a rapid increase in recent years in the use of electricity in steel manufacture in Germany. This ‘electric steel’ has a very uniform structure, but, if the cost is to be comparable with that produced by other means, the factor of safety has to be reduced. With so many high-frequency furnaces going intermittently, the power supply systems must be subjected to considerable peak demands. This is especially the case in the Ruhr, where, although there is a plentiful supply of coal, considerable reliance is placed upon the water-generated supplies from Austria to meet the heavy peak demands. The largest and one of the most interesting of the storage stations is situated at Herdecke on the banks of the Rhine about six miles south of Dortmund and nearly twenty miles east of Essen. It is connected with the control point at Brauweiler, which is on the Rhine between Cologne and Dusseldorf. By accumulating water in an elevated reservoir by means of pumps and the erection of the Herdecke power storage station and others in the district, the peak-load problem has been solved satisfactorily. Interesting details of this station are given in the Electrician of July 26.
