Embodiment Construction

[0042] in figure 1 The trajectory curve (also referred to as the movement trajectory) of the wide side of the vertical oscillation mold according to the prior art is shown in the one-dimensional oscillation. It can be directly known from the trajectory curve that the direction of movement of the crystallizer-and therefore the direction of movement of the wide-side plate-is correspondingly reversed at the top dead center OT and at the bottom dead center; in addition, For the speed v of the crystallizer in the two dead points OT and UT, v≡0 applies. In addition, the acceleration of the crystallizer in the dead points OT and UT just has the maximum value (if, for example, s=A.sin(ω.t) applies to the displacement s along the vertical y direction), then For the speed v and the acceleration a, v= =A.ω.cos(ω.t) and a= =-A.ω 2 .sin(ω.t). By having │a│=A.ω in the dead points OT and UT 2 The higher acceleration a and the higher friction associated with it are caused by the fact that t...

Abstract

The invention relates to a method and a device for oscillating a mold (1) of a continuous casting machine. The object of the present invention is to introduce a method for oscillating the mold (1) of a continuous casting machine, with which the continuous casting strand is better lubricated by casting powder and has a higher Less oscillating markers. This task is solved in that at least one wide side plate (3, 3a, 3b) of the crystallizer (1) runs horizontally along the width direction (H) of the wide side plate (3, 3a, 3b) Oscillation takes place at fH, where fV≠fH holds, and the numerical formula (I) for the velocity is greater than zero for all points of the trajectory of the broadside ( 3 ).

Description

Technical field [0001] The present invention relates to a method and a device for oscillating the mold of a continuous casting machine (also called a continuous casting mold). [0002] In one aspect, the present invention relates to a method for oscillating the Kokille of a continuous casting machine, wherein the mold includes two narrow side plates and two wide side plates, and the mold is along the vertical The direction of the support structure is fixed relative to the position at the first frequency f v Perform oscillation. [0003] In another aspect, the present invention relates to a device for oscillating the mold of a continuous casting machine, the device having: [0004] -A mold provided with a substantially rectangular shaped cavity, wherein the mold includes two narrow side plates and two wide side plates; and [0005] -A first oscillating mechanism for oscillating the crystallizer in a vertical direction relative to the fixed support structure. Background technique [000...
