Definitions
- the invention relates to a coolable oven roll for transporting continuous casting material a continuous casting plant by means of a heatable temperature compensation / reheating furnace, comprising a rotationally drivable, mounted outside the furnace Shaft, in particular with internal coolant channels, and with on arranged the shaft by means of a receiving bore forming a conveyor plane Carrying rings for the cargo.
- roller hearth furnaces of continuous casting plants for example, thin slabs are formed Rolling temperature preheated.
- the promotion of rolling stock or slabs through the roller hearth furnaces is done by oven rolls in different designs.
- the roller hearth furnace is usually in line between casting machine and rolling mill and is characterized by its function as a heating, balancing and and buffer zone. Due to the types of load of furnace rolls during the kiln operation showed the existing in the prior art types of furnaces different lengths of life on.
- the physical dimensions of such a furnace and its facilities for heat application, eg. Burner, are designed so that the furnace exit the Thin slabs have the required rolling temperature. It is a uniform Temperature distribution in the slab over its length, width and height at the kiln outlet unconditional requirement for subsequent rolling.
- the Oven length allows the inclusion of several thin slabs, which after casting - With different casting speeds - separated from the cast strand become.
- the transport of such thin slabs takes place within the furnace via driven Furnace rollers. These are at a certain kiln height at a level the transport height, arranged at predetermined distances from each other.
- the dimensions the roles are - relatively speaking - characterized in that the Diameter of the support rings and the shafts small compared to the length of the rollers is.
- the transport rollers in the roller hearth furnace can be equipped with a water cooling system be arranged or as a so-called. Dry rolls without cooling device be.
- the usual construction of a water-cooled roll comprises a plurality of support rings in axial distance on the water-cooled shaft.
- the latter is between the Tragringen insulated with refractory material, this insulating layer almost as well Thick is how the outer diameter of the support rings.
- the shaft is stored outside the furnace and there with connections for the internal shaft cooling Mistake.
- This internal cooling is achieved by a pipe with circular cross section, which is arranged concentrically in the shaft. Through this flows in cooling water, the tube passes through to the opposite side of the Furnace and flows on the other side into the annular gap between tube and shaft, flows through this and finally leaves the shaft on the inflow side.
- in the Annular gap between shaft and inserted pipe can become internals in the farthest Are located, which serve to fix the tube in the radial position and to increase the flow velocity of the water in the annular gap.
- the applied to the roller axle support rings are usually made Casting material and are made of high temperature nickel or cobalt base alloys produced.
- the shaft is preferably made of heat-resistant steels.
- the water cooled rolls are given priority, but not exclusively in the Heating zone used a roller hearth furnace. They are alternating in the transport direction equipped with a different number of support rings. Usually The waves are equipped with four or five support rings, usually alternately. The support rings are in the transport direction of a roll with four Carrier rings to the role with five carrier rings arranged on different lines. For the role with four support rings applies that in each case two support rings on a shaft half whereas on the reel with five support rings one in the middle of the reel, the others relative to those on the roll with four support rings outwards are arranged.
- the support rings on the shaft usually by welds secured against axial displacement.
- the torque can be over known Shaft-hub connections, such as Feather keys or also over welds be transmitted.
- a major reason for the failure of a furnace roller is the damage or destruction of the roller insulation, because just because the welds the high oven temperatures are directly exposed.
- the document EP 0 633 815 B1 describes a furnace roll for supporting a heated workpiece, which has a rotatable inner shaft for receiving a coolant having a number of axially spaced support rings are attached to this.
- a thermally resistant insulating agent that um the shaft is mounted, extends axially between the support rings, wherein the insulating means has an outer surface extending radially over at least a considerable part of the radius of a support ring pair extends.
- the insulating agent is secured in the shaft by anchoring means, with protruding Ends radially inward from the outer surface of the insulating means are arranged.
- the spacer is made of a metal which for the castable insulating a voltage drop in the thermal expansion the anchoring means and deflection of the furnace roller allows.
- the document DE 38 07 240 C1 describes a roller hearth furnace for heating of slabs, blocks, billets, sheets and the like warm goods, whose Furnace space is formed with a longitudinally extending roller table.
- the oven has a hot upper oven room, and a lower oven room, and in between a stove floor with recesses.
- the roller table is essentially in the sub-furnace space stored below the hearth floor and protrudes only with small sections its furnace rolls through the recesses of the hearth floors above its level.
- At least the roller sections projecting into the hot zone with their running surfaces, on which the warm goods are transported, are made of particularly heat-resistant Material which, composed of segments into a ring, the Cover the furnace rollers on the peripheral surface. Release cleaning devices the running surfaces of the oven rolls of troublesome scale caking.
- EP-A-1 189 004 proposes to improve the Heat transfer between support rings and shaft, in particular the heat dissipation from the support rings to increase the shaft and thus the availability To extend the support rings with reduced growth of scale and at the same time to ensure a safe torque transmission, as well as at reduced Workload greater flexibility in applying the support rings on the shaft, before, that the shaft at least at the receiving areas the support rings outer seats to form a polygonal Has cross-section, and that each support ring with polygonal positively locking inner mating surfaces is formed.
- the invention has the object basis, means for further improving the heat transfer between Specify support rings and shaft, thereby removing the heat from the Wear rings to increase the shaft significantly and the availability of the support rings to extend with reduced growth of scale and at the same time a reliable, safe torque transmission between support rings and shaft too ensure and with reduced workload when applying the Wear rings on the shaft to achieve greater flexibility in their arrangement.
- An embodiment of the measure according to the invention provides that the clamping rings consist of a copper-wrought alloy according to DIN 17 666.
- copper in addition to copper, they can also be made of a high thermal conductivity and comparatively soft copper / silver alloy.
- a further embodiment of the invention provides that a support ring with an opposite his rim thickened hub is formed, which on both sides annular Has recesses for receiving a pair of clamping rings.
- a support ring with an opposite his rim thickened hub is formed, which on both sides annular Has recesses for receiving a pair of clamping rings.
- a coolable oven roll 1 for the transport of Continuous casting material of a continuous casting plant by means of a heatable temperature compensation / reheating furnace, comprises a rotationally drivable, outside the Furnace mounted shaft 3 with internal coolant channels 4, 5.
- a conveying plane x-x forming support rings 7 arranged for transport.
- the support ring 7 has the Form of a circular disc and is in a preferred embodiment on his peripheral transport surface equipped with a carbide armor 12. Of the Support ring is pushed with a fitting hole 6 on the shaft 3 and takes in circular recesses 11, 11 'clamping rings 8, 8' on.
- Figure 2 shows an embodiment of the article of the invention, wherein the Support ring 7 is formed with a relation to its rim 7 'thickened hub 10.
- This can either, as shown in Fig. 3, both sides annular Have recesses 11, 11 'for receiving a pair of clamping rings 8, 8', but it can also be provided with an axially continuous receiving bore 6 ' be with a fit, e.g. a snug fit, for a one-piece use Clamping ring 8 'may be formed.
- furnace roller 1 can to prevent the formation of a heat transfer hindering oxide layer to each other in contact metal surfaces of the clamping rings 8 and the receiving bore 6, this with an electroplated noble metal layer, or coated with nickel.
