Description
Technical field
The present invention relates to the method and apparatus for making the crystallizer of conticaster (being also referred to as continuous cast mold) vibrate.
On the one hand, the present invention relates to a kind of method for making the crystallizer of conticaster (Kokille) vibrate, wherein said crystallizer comprises two narrow sides and two wide side plates, and vertically fixing relative to the position supporting construction of described crystallizer is with first frequency f
vvibrate.
On the other hand, the present invention relates to a kind of device for making the crystallizer of conticaster vibrate, this device has:
-being provided with the crystallizer of the mold cavity being essentially rectangle, wherein said crystallizer comprises two narrow sides and two wide side plates; With
-the first oscillating mechanism for making described crystallizer vertically vibrate relative to the supporting construction that position is fixed.
Background technology
For a long time, the known crystallizer supporting construction vertically fixing relative to position one-dimensionally that makes when continuous casting is vibrated.The continuous casting billet (Strang) formed in described crystallizer is on the one hand lubricated by the casting pulvis (Gie pulver) be applied on liquid steel, prevents described continuous casting billet to be attached on the copper coin of described crystallizer on the other hand.By the vibration of the one dimension of described crystallizer, described continuous casting billet has so-called vibration mark, and described vibration mark enters (Gie pulvereinzug), the heat dispersal situations of localized variation or disadvantageous tissue and has influence on continuous casting billet quality negatively due to transversal crack, casting pulvis.In addition known, the casting process of continuous casting billet or quality by the use of casting pulvis that is optimized or can be improved by the parameter (curve shape of amplitude, frequency, sinusoidal or anon-normal chordal shaped) be optimized that crystallizer vibrates.
In addition, known from JP2000042691A, the wide side plate of plate slab crystallizer is placed among vibration that is circular or ellipse.The disadvantage of this way is, described wide side plate vibrates with higher frequency (identical with the frequency of vibration vertically), and the amplitude when carrying out circular vibration for described vertical oscillation and horizontal oscillations must be equally high.In addition, the length of described geometric locus is shorter.Due to higher complexity, described method or described device are difficult to use actually.
Summary of the invention
Task of the present invention is, overcome the shortcoming of prior art and describe method and apparatus for making the crystallizer of conticaster vibrate, to be lubricated better by casting pulvis with described method and apparatus continuous casting billet and described continuous casting billet has less vibration marks.In addition, should than known, simple for the device of two-dimensional oscillations according to device of the present invention.
This task is resolved in the following manner for starting the method mentioned: at least one wide side plate (preferably two wide side plates) of described crystallizer flatly along the width of described wide side plate with second frequency f

v≠ f
h, and for described wide side plate geometric locus institute a little, the numerical value of speed
be greater than 0.
Confirming surprisingly when assessing two-dimensional oscillations pattern (geometric locus): particularly advantageously, is different for the frequency vertically vibrated with horizontal direction.Extend the length of described geometric locus in a cycle of oscillation thus, this point have impact on the lubrication of described casting pulvis very energetically.In addition, load is added to described continuous casting billet and described wide side plate very equably.In addition, very advantageously, the geometric locus of the wide side plate of described crystallizer does not have dead point (that is to equal zero for the numerical value of described speed described point, that is
).Prevent the direction of described wide side plate from reversing thus).
When carrying out two-dimensional oscillations, pass through

Supplementing as whole crystallizer (comprising described wide side plate) vibration vertically, according to the present invention, at least one wide side plate of described crystallizer, preferably two wide side plates are flatly vibrated along the width of described wide side plate (namely along the width of described continuous casting billet, wherein said width normal direction is in casting direction and thickness direction).By the geometric locus for described wide side plate a little the numerical value >0 of described speed,
this restriction of >0 ensures, the movement locus of described wide side plate is level and smooth and does not have dead point.Avoid thus described crystallizer, concerning tedious especially direction reversion the lubrication of described continuous casting billet.Can realize described continuous casting billet is more effectively lubricated when described casting pulvis identical in quality thus.On the other hand, for method according to the present invention, can casting rate-be improved with identical lubrication and boost productivity thus.
Because be incorporated in energy consumption to the frequency cube of described vibration, if so described first frequency f
vbe greater than described second frequency f
h, that is f
v> f
h, then the energy consumption for horizontal oscillations is low especially.
Scheme or as an alternative, advantageously, the amplitude of vertical oscillation is greater than or equal to the amplitude of horizontal oscillations as a supplement.Also the energy consumption for horizontal oscillations can be reduced thus.
