Abstract
The invention relates to a device for casting strands of metal, in particular steel, having a material supply container via the pouring nozzle of which the liquid metal is transferred onto the carrying side of a revolving conveyor belt, wherein the conveyor belt is made of a thin, heat-resistant belt circulating between a first and a second deflection roller, said belt having the shape of a trough after the first deflection roller and in the region of the outlet nozzle for receiving the liquid metal, and reassuming the shape of a flat belt near the second deflection roller. In order to decrease the strain on the belt, the invention proposes that at least one of the deflection rollers be crowned in a convex fashion.
Claims (21)
1. Device for casting strands of metal, in particular steel, with a material supply vessel, the liquid metal being delivered to the carrying side of a circulating conveyor belt by means of the pouring nozzle of the material supply vessel, wherein the conveyor belt comprises a thin, heat-resistant belt which circulates between a first deflection roller and a second deflection roller and which is shaped after the first deflection roller and in the region of the outlet nozzle to form a trough for receiving the liquid metal and resumes the shape of a flat belt in proximity to the second deflection roller, characterized in that at least one of the deflection rollers is cambered in a convex manner.
2. Device according to claim 1, characterized in that the camber is selected in such a way that the shortening of the belt resulting from the formation of the trough profile is at least partially compensated.
3. Device according to one of the preceding claims, characterized in that the camber resulting from the trough profile is calculated according to the following formula:
(1) B B/2 = X B+X+X T
(2) .DELTA.L XB = L - L v =
(1) B B/2 = X B+X+X T
(2) .DELTA.L XB = L - L v =
4. Device according to claim 1, characterized in that the change in length of the belt due to the varying temperature distribution over the width of the belt is taken into account in the camber and is calculated according to the following formula:
(3) .DELTA.l Temp = L Trough.alpha.(T M - T R).
(3) .DELTA.l Temp = L Trough.alpha.(T M - T R).
5. Device according to claims 3 and 4, characterized in that the optimum camber of the deflection rollers for a homogenized tensile stress over the width of the belt is calculated for a given trough profile (casting format) and temperature profile by superposition.
6. Device according to one of the preceding claims, characterized in that the camber of the first deflection roller is smaller than that of the second deflection roller.
7. Device according to one of the preceding claims, characterized in that the camber can be changed, e.g., by means of a pressure medium, in at least one of the deflection rollers.
8. Device according to claim 7, characterized in that a profiled cavity is provided at the roller shell for applying pressure.
9. Device according to one of the preceding claims, characterized in that the entry length and exit length, respectively, is greater than 500 mm.
10. Device according to one of the preceding claims, characterized in that the maximum entry length or exit length is selected in such a way that the camber due to the trough profile is not greater than 2%.
11. Device according to one of the preceding claims, characterized in that the belt is shaped by the deflection roller continuously over the distance Le(a) to form the trough profile or flat belt.
12. Device according to one of the preceding claims, characterized in that the belt material comprises a thermal shock-resistant alloy based on CuNi, Fe.
13. Device according to one of the preceding claims, characterized in that the belt material comprises a single-phase or multiple-phase Cu alloy.
14. Device according to one of the preceding claims, characterized in that the belt material comprises a nickel-based alloy.
15. Device according to one of the preceding claims, characterized in that the belt has a thickness from 0.5 mm to 2.0 mm.
16. Device according to one of the preceding claims, characterized in that the trough profile is arc-shaped.
17. Device according to one of the preceding claims, characterized in that the trough profile is symmetrical.
18. Device according to one of the preceding claims, characterized in that the trough profile has substantially straight-line regions at both ends.
19. Device according to one of the preceding claims, characterized in that the sides of the trough profile are higher than the casting profile by 10 mm.
20. Device according to one of the preceding claims, characterized in that the side areas have an angular deviation of +/- 25 degrees relative to the perpendicular.
21. Device according to one of the preceding claims, characterized in that the trough profile can be adapted to the shrinkage of the casting cross section by a deliberate adjustment of the rollers in casting direction over the length of the trough.
