<p>Introduced are a block using ferronickel slag, a method for producing the same, and a device for producing the same. Energy efficiency is improved, and environment contamination can be prevented. Also, a brick having an ensured level of strength which is the same as or higher than a standard value can be produced. The method of the present invention comprises the steps of: preparing high temperature ferronickel slag having a particle size of 0.6-12 mm and produced in an electric furnace steelmaking process; pulverizing the ferronickel slag to have a size of 5 mm or less; sorting the ferronickel slag by particle size; absorbing heat radiated from the ferronickel slag using a fluid; sorting the pulverized ferronickel slag through magnetism in order to be classified into magnetically attachable powder and magnetically non-attachable powder; drying the ferronickel slag; mixing the pulverized slag and a new aggregate by heating the same using the heat absorbed from the ferronickel slag; and molding the same.</p> |
