A blast furnace cooling arrangemenet comprises a cooling screen which is disposed in an annular space between a furnace shell and its lining, and which is formed by vertically arranged rows of plates provided with main and additional internal ducts having common inlets and common outlets. Mounted above the cooling screen are drum separators which communicate through supply pipelines and take-off pipelines with the common inlets and outlets of the main and additional ducts of the plates of each vertical row, the above elements forming closed circuits of natural circulation of a cooling medium. Connected at the common inlets and outlets of the additional ducts of the vertical rows of the plates are circuits of forced circulation of a cooling medium. Each of the circuitsof forced circulation comprises a container communicating with the common outlet of the additional ducts, a heat exchanger connected with the container, and a pump communicating through its inlet with the heat exchanger and through its outlet with the common inlet of the additional ducts in the vertical row of the plates. The common inlets and outlets of the additional ducts are provided with distributing valves intended to selectively connect the additional ducts to the circuits of natural and forced circulation of a cooling medium.

Blast furnace cooling arrangement

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.

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.

The arrangement for cooling the bottom of a blast furnace comprises cooling plates mounted between the furnace lining and shell and forming vertical and horizontal rows. Each cooling plate incorporates coil pipes situated in two planes parallel to the furnace shell, the coil pipes being connected to each other in vertical rows. There are at least two coil pipes in one of the vertical planes in each plate. Such coil pipes in the plates mounted in the uppermost horizontal row are connected to coil pipes mounted in the top portion of the furnace in two different vertical planes. At least one coil pipe is situated in the other vertical plane in each cooling plate. The coil pipes in the plates mounted in the lowermost horizontal row are controllably connected to cooling medium feed collectors of the furnace common cooling system and to a high-pressure cooling medium source. Same coil pipes incorporated in the plates mounted in the uppermost horizontal row are controllably connected to the cooling medium return collector of the furnace common cooling system and to a high-pressure cooling medium receiver.
