Cooling plate for metallurgical furnace

A cooling plate for a metallurgical furnace comprising:

• a body with a front face and an opposite rear face, the front face being turned towards a furnace interior when the cooling plate is in use;
• a cooling channel formed in the body and having an opening in said rear face;
• a coolant feed pipe being connected to said rear face and being in fluid communication with said cooling channel;
• an emergency cooling tube arranged within said cooling channel, said emergency cooling tube having a cross-section smaller than a cross-section of said cooling channel;
• connection means disposed on an end section of the emergency cooling tube for connecting an emergency feed pipe thereto, said connection means being arranged within said cooling channel or said coolant feed pipe;
• wherein, in a normal operation, coolant is fed to the cooling channel via the coolant feed pipe whereas the connection means of the emergency cooling tube is physically disconnected from the emergency feed pipe;
• and wherein, in an emergency operation, the feeding of coolant through the coolant feed pipe is interrupted and the emergency cooling tube is physically connected to the emergency feed pipe via the connection means, whereby coolant is then fed via the emergency feed pipe to the emergency cooling tube.
