A cooling plate for an iron and steelmaking furnace includes a copper cooling plate body having at least one cooling duct for a cooling medium extending essentially parallel with the back of the cooling plate body. The cooling plate body further includes a preformed, externally accessible recess into which the cooling duct opens. A connection piece is utilized as a cooling medium connection on the back of the cooling plate body, while a formed piece fitted within the externally accessible recess forms a deflection surface for the cooling medium flowing from the connection piece into the cooling duct, or from the cooling duct into the connection piece.

Cooling panel for a furnace for producing iron or steel

A cooled furnace wall comprises a furnace shell with an inner and an outer side and cooling plates lining the inner side of the furnace shell. Each of the cooling plates has a plate body and protruding connection pieces for supplying the cooling plate with a coolant. The furnace shell has connection openings therein for interconnecting the connection pieces of adjacent connection plates from the outer side of the furnace shell. At least one of the connection pieces is formed by a tube bend that protrudes from an edge face of the plate body and that has a connection end to extending through one of the connection openings in the furnace shell.

Cooled furnace wall

A cooling system for a blast furnace includes a cooling circuit ( ) closed by a return line ( ) and at least one circulation pump ( ) for circulating cooling water through the closed cooling circuit. An emergency feed line ( ) with an emergency feed valve ( ), which opens in case of a power failure, is connected to the cooling circuit ( ). An emergency overflow valve ( ) is located at the highest point of the closed cooling circuit ( ). This emergency overflow valve ( ) opens in case of a power failure, so that the closed cooling circuit ( ) becomes an open cooling circuit ( ) with an atmospheric pressure discharge at its highest point. A pressure vessel ( ), which is connected to the emergency feed line ( ), contains a certain volume of emergency water which is pressurised by a gas, so that, in case of a power failure, an emergency water flow establishes through the open cooling circuit ( ).
