In order to configure a bell and hopper for shaft furnaces, in particular, blast furnaces, comprising a charging bin with a feed tube, a rotating chute carrier with rotary drive, a swiveling chute in the interior of the furnace with drive means arranged external to a housing, in a less failure-prone and a wear resistant way, the drive means for the swivel movement of the chute are to comprise: at least one motor ( ) which drives by a respective pinion ( ) a crown gear ( ), wherein the crown gear ( ) engages the spindle gear wheels ( ) of at least two spindles ( ) distributed about the periphery of the bell and hopper external to the rotating chute carrier ( ) for generating a lifting and lowering movement of the spindles, as well as means ( ) for transmitting this vertical movement of the spindles onto the tilting shafts ( ), which penetrate the inner wall ( ) of the chute carrier ( ) and from which the chute can be suspended, for generating a swivel and tilting movement of the chute.

Bell and hopper for shaft furnaces

A cooling plate for shaft furnaces, particularly blast furnaces, is provided with a refractory lining and is composed of copper or a low-alloy copper alloy with cooling medium ducts, wherein the cooling plate is made from a wrought or rolled ingot, and wherein the cooling plate has on one side thereof, i.e., the front side, grooves for receiving refractory material. Cooling ducts are provided on the rear side of the cooling plate, wherein the cooling ducts are defined in part by the cooling plate itself and in part by sheet metal or sheet steel, wherein the cooling ducts are produced by milling cutting in the rear sides of the cooling plate and/or the sheet metal or sheet steel.

Cooling plate for shaft furnaces

Cooling plates for shaft furnaces, particularly blast furnaces, provided with refractory linings, are made of copper or a low-alloy copper alloy and are provided with cooling agent ducts in their interiors. Each cooling plate is manufactured from a rough forged or rolled ingot, wherein the cooling plate has a straight or planar inner side and the cooling ducts are blind-end bores extending in the interior of the cooling plate, wherein the cooling plate is provided at the edge thereof with side flanges, and wherein pipe connections are provided at the ends of the cooling ducts. The cooling body of the forged or rolled copper cooling plate provided with inner blind-end bores and vertical and/or horizontal side flanges on both sides has an arched outer side as well as a planar inner side.

Cooling plates for shaft furnaces

A top closing device for shaft furnaces, particularly blast furnaces, including an inlet hopper with inlet pipe, a rotating, vertically non-adjustable chute carrier with rotary drive, a pivotable chute in the furnace interior with external drive means, and sealing members between the rotating and stationary components. The rotating chute carrier is mounted with a gear ring attached to a flange in a ball bearing slewing rim arranged on a catch basket. The rotary movement of the rotating chute carrier is effected outside of the furnace space by an electric motor drive with pinion. The catch basket is arranged on the furnace support ring of the gas seal hood. The pivoting or tilting movement of the chute relative to the furnace axis within the rotating chute carrier is effected by a hydraulic or electromechanical drive outside of the furnace space. An annular sealing member for sealing relative to the rotating chute carrier is mounted on the furnace support ring next to the flange of the catch basket. An annular sealing member for sealing relative to the stationary inlet pipe is mounted on the inner flange of the chute carrier.

Top closing device for shaft furnaces

Plate coolers including a plate cooler made of copper or a low-alloy copper alloy for shaft furnaces, especially blast furnaces, with blind holes arranged in the cooling body for passing through cooling water, as well as with vertical side flanges arranged around the cooling body and with horizontal side flanges. The plate cooler can be connected to another plate cooler to form a plate cooler segment or plate cooler ring. Webs and grooves located between them are arranged in the plate cooler in the area of the cooling body on a side facing the interior of the furnace for holding refractory material.

Plate coolers for shaft furnaces

The present invention concerns a plate (1) for cooling a blast furnace and forged or rolled out of a blank of copper or mainly-copper alloy. Vertical bores (3) extend into the plate. A detachable furnace-cooling component (4) with vertical bores (5) and horizontal bores (6) extending into it is attached to the top or bottom of the plate. Coolant is pumped into and out of the bores in the furnace-cooling component through sections (2) of pipe and into and out of the bores in the plate through other sections (2) of pipe. Both cooling systems communicate with the furnace's cooling system by way of the pipe sections (2), which extend through the furnace plating (10).

Plate for cooling shaft furnaces

The present invention concerns a slab (1) for cooling a blast furnace and made of a mass of copper or high-copper alloy forged or rolled into a blank. The edges of the slab accommodate narrower vertical and horizontal part-way bores (13 & 14) disposed around vertical part-way bores (3). Coolant is supplied to and removed from the narrower bores through sections (5 & 5') of pipe and to and from the other bores though connections (2 & 2'). The slab can be additionally secured to the furnace's armor by way of a cutout (12) in the surface facing away from the interior of the furnace and engaged by a bolt mounted on the armor. The slab is secured to the furnace by fasteners that engage threaded bores (9) in the slab.
