Definitions

  • the invention relates to a conveyor belt of a continuous casting machine for casting strips of metal, in particular steel, which is guided in a drivable drum and from this horizontally adjacent to the belt tension adjustable drum and is supported on a support arranged between the drums, and that of the Cooling belt facing side is cooled.
  • a conveyor belt is known, for example, from document DE 34 23 834 C2, in which a metal belt is guided over support rollers and cooled on its surface facing away from the cast strand.
  • the metal strip is guided around several support rollers, at least one of which serves as a tension roller for the metal strip and at least one of which is driven in rotation.
  • the conveyor belt on the side facing the cast strand heats up to such an extent that warps occur which protrude into the cast strand and deform it.
  • the bumps that occur here reach dimensions perpendicular to and away from the plane of the conveyor belt in the order of magnitude of the conveyor belt thickness and a multiple thereof. In the conveyor belt level, these dents can reach dimensions of 10 to 20 times the conveyor belt thickness and in the plane perpendicular to Conveyor belt direction have a size of 0.8 to 0.9 of the cast strand width.
  • a guide plate is arranged at a short distance behind the mold belt, which has inlet and outlet openings for the cooling liquid, flows through the cooling liquid onto the back of the mold belt and cools it over the entire surface, with a positive and an in relation to the surrounding atmosphere generates a negative hydrostatic pressure field so that the mold belt takes a certain distance from the guide plate and is thus held and guided stably over the entire area of the casting space.
  • the thickness of the mold belts is between 0.5 and 2 mm.
  • the proposed device is used in downwardly inclined pouring devices in which there is a relatively high pressure on the mold belts and on their supports in the deep metal sump in the cast material due to the metallostatic pressure. In the absence of such a strong back pressure, for example in the case of continuous strip casting equipment Conveyor belts horizontally guided cast strands, there will still be significant warping due to the low weight of the cast strand.
  • the invention has set itself the goal of creating a maintenance-friendly and generic conveyor belt which, with a long service life, easily avoids quality defects in the cast strand which are caused by wavy warping of the conveyor belt in the macro range.
  • the invention achieves this aim by the characterizing features of claim 1.
  • the conveyor belt is given a shape while maintaining its flexibility, which allows bulging in the micro range, but at the same time is structured in such a way that warping in the macro range is reliably avoided.
  • blind holes are provided on the conveyor belt, which have a round or polygonal shape and have such a small wall thickness on the head side, which allow a membrane-like deformation in the shadow of the blind hole, but whose webs have such a high strength that no macro bumps occur.
  • the blind hole bases are designed so that they bulge ⁇ 1 mm. These slight changes in shape do not cause any quality-reducing deformations in the cast strip to be produced.
  • the overall conveyor belt remains in its dimensions, both in length and in width, and also in length Height within the given limits.
  • the outer surface of the endless conveyor belt that is to say the surface that comes into contact with the cast strand, is made of a material with high thermal conductivity, for example copper , built up, while the cooled grille, in particular taking over the tensile forces, consists of a material that is resistant to bending and temperature changes, for example fine-grained steel.
  • the total number of openings i.e. the blind holes to the solid material, i.e. the rods, is selected between 15-40%, taking into account the material used, the dimension of the strip is selected such that, apart from the desired microbumps, no other deformations outside of predetermined limits occur .
  • FIG. 1 shows a storage container 11 of a belt casting device in which there is liquid material M, the bath level of which is raised above the spout 12 by negative pressure p.
  • the metal flowing out of the spout 12 meets a conveyor belt 21 and is conveyed away from the storage container in the form of a cast belt 13.
  • the conveyor belt 21 of the conveyor device has a drum 25 driven by a motor 26 and a drum 27 tensioned by a tensioning device 28.
  • the upper run of the conveyor belt 21 is supported on supports 51 and is cooled by cooling water guided by spray nozzles 41 on the side opposite the cast belt 13.
  • FIG. 2 shows in section a part of the conveyor belt 21 into which blind holes 22 have been introduced.
  • the blind hole bottoms have a wall thickness d, with a blind depth T remaining for the conveyor belt thickness D for the blind holes 22.
  • the blind hole top surface 29 can be sprayed with a cooling medium, so that a bulge D of the blind hole bottoms 24 occurs due to the temperature difference between the side of the blind hole bottom 24 which tends towards the casting bath 13 in comparison with the cooled blind hole top surface 29.
  • a conveyor belt in sandwich construction consisting of two layers 31 and 32 which are intimately connected to one another, the layer 31 facing the cast belt corresponding to the thickness d of the sack lock bottoms 24 and the layer 32 facing away from the cast belt 13 a grid is built up in the height of the blind hole depth T.
  • blind hole shapes are shown, specifically blind holes with a circular or hexagonal shape, which have the minimum spacing S from one another.
