Cooling arrangement for shaft furnaces

The tubular cooled members have straight pipes, each accommodating an insert aligned axially therewith and having a cross-section diminishing in the direction of the coolant flow in the pipe interior. These straight pipes are coupled in pairs by a bent connecting pipe fitted with an insert abutting against those enclosed in said straight pipes. The abutted pipes have the same diameters but the junctions between said pipes are displaced relative to those between the inserts, the inserts also having the same diameters at the abutted sections.

Tubular cooled members of metallurgical furnace

A cooler for a shaft furnace comprises a metal plate for protecting the furnace walls from the heat effect arranged in the way of heat flow and a means for cooling said plate. The plate is made in the form of metal pipes filled with a coolant and sealed at the ends thereof. The coolant-filled ends of the pipes are rigidly fixed to the plate, and the coolant-free ends of said pipes are mounted within a cooling chamber with the coolant circulating therethrough. The cooling chamber is arranged exteriorly of the furnace wall. The coolant-free ends of the pipes are disposed slightly above those filled with the coolant. The plate is formed of two layers, namely, a high-heat-conducting layer and a low-heat-conducting one, the former facing the furnace working space and the latter being presented to the furnace wall. The interfacial plane of the layers is parallel to the longitudinal axis of the pipes. The present invention can be advantageously used for the protection of blast-furnace shells.

Cooler for a shaft furnace

A roof in which beams-headers rest on a roof ring and carry loop-shaped tubes suspended from and coupled with the said beams-headers which are running transversely to the framework tubes. Welded edgewisely to the top generatrices of the tubes are metal straps with bricks placed at least in one layer in rows therebetween. The brick end portions rest on the adjacent tubes, so that the brick in each row are disposed with a clearance sufficient to enable thermal expansion of the brick both vertically and horizontally when heated.

Cooled roof of electric furnace

A contrivance for the protection of the walls of a shaft furnace from heat effect comprising a metal plate serving to shield the surface of walls facing the interior of the furnace and at least two essentially U-shaped tubes for a coolant linked up with the plate and attached to the furnace wall with their open ends. The plate is more longer in the vertical direction than wide in the horizontal one and is made up of separate blocks, each block being more wider in the horizontal direction than long in the vertical one and is provided with grooves accommodating the tubes in that surface which faces the furnace wall. The grooves are lined with a layer of heat conductor, and provided in the intervals between the grooves are means of fastening each block to the tubes which, in their turn, are provided with fasteners welded thereto and serving the purpose of attaching to the wall.
