Description
DEVICE FOR CASTING STRANDS OF METAL
The invention is directed to a 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 pouring 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.
A device of the type mentioned above is known from Japanese Publication A, in which the trough shape of the belt is achieved by means of vertical and horizontal conveying rollers which are arranged along the conveying path between the two deflection rollers and act on the belt.
Due to the relatively large differences in temperature along the width of the belt which act on the belt through the liquid-metal and because of the deformation of the belt from the flat shape to the trough shape and then back again into the flat belt shape, there are widely varying changes in length along the width of the belt resulting in critical stresses on the belt material, particularly in the edge area.
Although the belt - a steel belt is usually used for this purpose - has an elasticity corresponding to the belt material that is used, a cost-effective lifetime cannot be achieved as a result of the different stresses on the belt along the width.
-1a-Some embodiments of the invention may provide a device in which the stresses on the belt are reduced and evened out. Further, new materials may be used for the belt material because of the reduced, more uniform stress on the belt.
Further, the entry length and exit length may be adapted to the geometry of the trough profile for specific adjustment of the degree of camber. This may increase the cost effectiveness of the casting process appreciably.
According to an aspect of the invention, at least one of the deflection rollers is cambered in a convex manner.
According to another aspect of the invention, there is provided a device for casting strands of metal, the device comprising: an outlet nozzle configured to supply liquid metal from a material supply vessel; a circulating conveyor belt assembly being configured to receive the liquid metal from the outlet nozzle on a carrying side, the conveyer belt assembly comprising: a first deflection roller; a second deflection roller; and a thin, heat-resistant belt that circulates between the first deflection roller and the second deflection roller, the belt being comprised of a belt material and being shaped to form a trough having a trough profile for receiving the liquid metal between the first deflection roller and the second deflection roller in a region of the outlet nozzle, the circulating conveyor belt resuming the shape of a flat belt proximate to the second deflection roller, wherein at least one of the first deflection roller and the second deflection roller is convexly cambered to form a camber, and wherein the camber is configured to at least partially compensate for a shortening of the belt resulting from the formation of the trough profile.
Owing to a deliberate cambering of at least one of the deflection rollers, by which the shortening of the belt resulting from the formation of the trough profile is at least partially compensated and because the different temperature distribution along the width of the belt is also taken into consideration in the camber, the stress on the belt is made homogeneous, which has a positive impact on the life of the belt.
It is advantageous when the camber of at least one of the deflection rollers can be varied by a pressure medium to compensate for the change in length, e.g., due to modified casting parameters. To this end, a profiled cavity is provided in the roller shell. In this connection, it can also be advantageous when the camber of the first deflection roller, for example, is smaller than that of the second deflection roller.
The camber can be calculated based on the geometry of the trough profile. The average trough profile is used for the calculation when the trough profile varies over the length of the trough to adapt to the shrinkage of the casting profile.
Details are shown in Figures 1 to 4.
The drawings show:
Figure 1 a schematic view of the belt with the deflection rollers in a side view;
Figure 2 a cross section through the trough shape Figure 3 the calculation model with a simplified trough shape as a rectangular shape for the calculation and cambering of the deflection roller; and Figure 4 the trough cross section for calculating the influence of temperature.
The camber is a function of the respective belt length Le (entry length) and La (exit length) between the deflection roller and the trough profile or, conversely, of the belt width BB, trough width B-1, trough height HT and trough profile, where a rectangular longitudinal shape is assumed for purposes of the calculation.
The camber is yielded by: f(Le(a),BB,BI,Hi-, trough profile.
The calculation of the camber can be carried out for every point of the deflection roller between points A and B of the trough profile with coordinates X and Y
and length Le(a) for half of the belt width BB between points C and D. The calculation of the camber must be carried out for the entry side and exit side.
The calculation of the different belt length owing to the varying temperature distribution over the width of the belt can be carried out in a simplified manner according to the indicated formula. For an exact calculation, the temperature profile over the width of the belt is calculated corresponding to the casting parameters.
By means of the two formulas, the optimum camber of the deflection rollers for homogenized tensile stress over the width of the belt can be calculated for a given trough profile (casting format) and temperature profile by superposition:
(1) BB/2 = XB+X+X'r (2) ALXB=L-Lv = L2+X2+Y2 (3) Al temp = LTrougha (TM - TR

The camber of the first deflection roller is preferably smaller than that of the second deflection roller.
The camber should be changeable, e.g., by means of a pressure medium, in at least one of the deflection rollers. To this end, a profiled cavity can be provided at the roller shell for applying pressure.
