A metallurgical furnace provided with a refractory lining and an outer furnace steel jacket, having copper cooling plates, wherein a flow of cooling medium flows through the cooling plates arranged between the furnace steel jacket and the refractory lining. Cooling medium pipes of the copper cooling plate provided for supplying and removing the cooling medium are guided through the furnace steel jacket to the exterior and are gas-tightly welded to the furnace steel jacket. The copper cooling plate is connected free of play in all spatial directions to the furnace steel jacket, in addition to attachment by way of the cooling medium pipes welded to the furnace steel jacket, by at least one fixed-point fastening element that is welded to the furnace steel jacket. The at least one fixed-point fastening element is arranged within at least one of the upper part and the lower part of the copper cooling plate in immediate proximity of the cooling medium pipes.

Copper cooling plate for metallurgical furnaces

The invention relates to a throat closing device for shaft furnaces, especially blast furnaces having a material feeding hopper ( ), to which a temporarily rotating rotary hopper ( ) which is sealed with regard to the stationary parts ( ) is connected. The inventive throat closing device is produced such that it has a less complex construction and is easier to install, and can be easily serviced due to the provision of a sealing unit ( ) comprised of an adjusting flange ( ) which is arranged above the rotary hopper ( ), is complementary to the hopper flange ( ) thereof, can be lifted and lowered, and which comprises seals ( ) located on the flange underside. Said sealing unit is configured in a spanning wall ( ) which comprises a compensating element ( ) and which connects the adjusting flange ( ) to the stationary part ( ) of the rotary hopper ( ).
