   WM reinem pulverisiertem Koks, besteht, zugesetzt werden, welches Material gründlich mit dem Eisenerz oder dem Erzgemenge vermischt werden muss, bevor das Kohlehydrat und das Wasser   beigemengt wird. 



   Das in der vorbesohriebenen Weise vorbereitete Erzgemenge wird in einem geeigneten Gefäss oder Herdofen (z. B.   Siemens'sehen     Gas-Regenerativofen)   eingebracht und über den   Schmelzpunkt   des herzustellenden Metalles erhitzt. Der Feuerraum des anzuwendenden Herdofens wird mit einer geeigneten, feuerbeständigen, vorzugsweise kohlenstoffhältigen Ausfütterung versehen. Wenn die Erzbeschickung einer Hitze von 1400 bis 1650  C oder darüber durch einen Zeitraum von 2 bis 5 Stunden (und darüber), je nach der Grösse der Beschickung 
 EMI2.1 
 seiner Eigenschaften und hoher Güte   gleichkommt.   



   Wenn ein Stahl herzustellen ist, der andere Metalle enthalten soll, wird ein geeignetes Gemenge solcher Erze, welche diese Metalle in den gewünschten Mengenverhältnissen aufweisen, mit der Erzbeschickung zusammengebracht und die geforderte Stahllegierung wird in den meisten Fällen durch die eine Operation resultieren.

   WM pure powdered coke, consists of adding which material must be thoroughly mixed with the iron ore or ore mixture before the carbohydrate and water are added.



   The ore mixture prepared in the manner described above is placed in a suitable vessel or hearth furnace (e.g. Siemens' gas regenerative furnace) and heated above the melting point of the metal to be produced. The combustion chamber of the hearth furnace to be used is provided with a suitable, fire-resistant, preferably carbon-containing lining. When the ore charge is heated to 1400 to 1650 C or above for a period of 2 to 5 hours (and above) depending on the size of the charge
 EMI2.1
 its properties and high quality equals.



   If a steel is to be produced which is to contain other metals, a suitable mixture of such ores, which contain these metals in the desired proportions, is combined with the ore charge and the required steel alloy will in most cases result from the one operation.
