Problems solved by technology

[0015] The smooth bending and straightening curve not only ensures the continuity of the curvature but also the continuity of the curvature derivative, which effectively reduces the stress on the rollers. Because in the actual layout of the casting machine, especially to reduce the sagging of the billet, when the rollers are arranged closely , the position coordinates of the rollers have little difference, only a few to a few tenths of a millimeter, and the installation accuracy is too high, which cannot be guaranteed in practice

[0033] figure 1 It is a schematic diagram of the outer arc and inner arc of the straight arc continuous casting machine. The roll row curve of the continuous casting machine includes inner arcs and outer arcs parallel to each other. The arc is obtained by interpolation in the normal direction, so the design of the outer arc is particularly important. As shown in the figure, the outer arc of the continuous casting machine is composed of the mold section J01, the vertical section H12, the bending section S23, the basic arc section S34, the straightening section A curve smoothly connected by the straight section S45 and the horizontal section L56. in,

[0120] The roll row curve of the full-arc continuous casting machine designed by the method of mixed bending and straightening is similar to that of the straight-arc continuous casting machine. Figure 6 It is a schematic diagram of the outer arc and inner arc of the full arc continuous casting machine. As shown in the figure, the outer arc and inner arc of the full arc continuous casting machine are similar to the straight arc continuous casting machine, but the full arc continuous casting The outer arc and inner arc of the casting machine do not include the vertical section and the curved section. Taking the outer arc of the full-arc continuous casting machine as an example, it is the mold section J01, the basic arc section S14, the straightening section S45, A curve smoothly connected by the horizontal segment L56, where,

Abstract

The invention provides a continuous casting machine roller array curve design device and method. The device comprises a display input unit, a calculation unit, an interpolation unit, a modeling unit, an obtaining unit and a roller arranging unit. The display input unit is used for inputting bending straightening conditions and design parameters and displaying roller array curves and key point and interpolation point coordinate values. The calculation unit calculates outer arc and inner arc key point and interpolation point coordinates in a mixed bending straightening mode. The interpolation unit performs interpolation among the key points. The modeling unit builds a continuous casting machine outer arc and inner arc models according to the key point and interpolation point coordinates calculated by the calculation unit. The obtaining unit obtains mixed coefficients according to the models and the roller mounting accuracy to obtain outer arc and inner arc key point and interpolation point coordinate values. The roller arranging unit arranges rollers on the continuous casting machine outer and inner arcs according to space between rollers to obtain coordinates of the centers of all the rollers to obtain the continuous casting machine roller array curve. By means of the device and the method, stress of the rollers is reduced effectively, and the mounting accuracy requirement is met.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to a device and method for designing roll row curves of a continuous casting machine. Background technique [0002] Due to the popularization and application of high casting speed technology in the continuous casting machine, the bending and straightening of the slab are carried out in the state of incomplete solidification. In order to reduce the tendency of cracks in the slab, the bending strain and straightening strain of the slab in the entire bending zone and straightening zone must be controlled within a certain range, which requires precise control of the design of the roll curve of the continuous casting machine. In the design of the roll row curve of the continuous casting machine, one-point bending straightening, multi-point bending straightening, and continuous bending straightening are commonly used. The curvature of the continuous bending straightening curve is continuous, wh...
