Abstract
The utility model provides a continuous casting crystalizing device vibrator. According to the arts demand, the appropriate vibration curve and vibration parameter are arbitrarily selected. The device consists of a base, an eletro-magnetic vibration exciter installed on the base, vibrating elements of the device connected with the continuous casting crystalizing device rigidly, an antivibrator connected between the base and the continuous casting crystalizing device, and a spring connected between the base and the continuous casting crystalizing device. Compared with the existing vibrator, because the utility model adopts the eletro-magnetic vibration exciter as a vibration execution component, according to the arts requirement the utility model can select the combination with various amplitudes and frequencies, and therefore the quality of the continuous casting billet surface is increased obviously. In addition, because the form of the existing continuous casting crystalizing device is not required to alter, and the technical project can be implemented, not only the utility model can be applied to new-built continuous casting production line, but also the utility model is also used for the technical reformation of the existing equipment.
Description
Technical field
The utility model relates to starting of oscillation equipment, particularly a kind of vibrating device that makes the continuous cast mold starting of oscillation.
Background technology
In continuous casting is produced,, crystallizer is produced pump in order to prevent crystallizer and strand adhesion and strand to be moved downward along crystallizer internal cavity.Great majority all adopt motor driving cam mode to make continuous cast mold produce vibration now, and in this mode, the frequency of crystallizer sinusoidal vibration and amplitude thereof preset by the offset of adjusting motor rotary speed and cam respectively.When optimizing casting process, selecting suitable mold oscillation parameter is an important mode with the best of breed that obtains amplitude and frequency.Well-knownly be, when crystallizer during by the sinusoidal manner vibration, its vibration parameters is combination arbitrarily, is to utilize some mechanical means to the way of this solution, makes crystallizer realize that the non-sine mode vibrates by force.Problems such as it is inconvenient that but these mechanical means all exist vibration parameters to adjust, and crystallizer can produce lateral vibration, and parts are easy to wear have influence on the raising of slab quality the most at last.
Germany Shu Luman-Si Ma company proposed a kind of make the continuous cast mold vibration by hydraulic lift, it can regulate vibration parameters in a big way, thereby has improved the quality of strand.But this method still can't change the shape and the vibration parameters of oscillating curve according to the technological parameter of continuous casting arbitrarily, and in addition, because the complexity of hydraulic system self, its manufacturing and maintenance cost are all very high.
Summary of the invention
The purpose of this utility model is to provide a kind of continuous cast mold vibrating device, and it can select suitable oscillating curve and vibration parameters arbitrarily according to arts demand.
Above-mentioned purpose of the present utility model realizes by following technical proposal:
A kind of continuous cast mold vibrating device comprises:
Pedestal;
Be installed in the electromagnetic exciter on the described pedestal, its vibrating elements and continuous cast mold are rigidly connected;
Be connected the damper between described pedestal and the continuous cast mold; And
Be connected the spring between described pedestal and the continuous cast mold.
Reasonable is that in above-mentioned continuous cast mold vibrating device, described electromagnetic exciter is positioned at the below of described continuous cast mold, and the direction of vibration of described vibrating elements is perpendicular to described base-plates surface.
The utility model is compared with existing vibrating device, owing to adopt electromagnetic exciter as the vibration execution unit, therefore can select the combination of various amplitudes and frequency according to technological requirement, thereby significantly improve the quality on continuous casting billet surface.In addition, can realize technique scheme, so the utility model not only can be applicable to newly-built continuous casting line, but also be applicable to technological transformation existing device owing to need not to change existing continuous cast mold form.
Description of drawings
By below in conjunction with the description of accompanying drawing to the utility model preferred embodiment, can further understand the purpose of this utility model, feature and advantage, wherein:
Fig. 1 is the front view according to the continuous cast mold vibrating device schematic diagram of the utility model embodiment.
Fig. 2 is the side view according to the continuous cast mold vibrating device schematic diagram of the utility model embodiment.
Fig. 3 is the mechanical model schematic diagram of continuous cast mold vibrating device illustrated in figures 1 and 2.
The specific embodiment
Below by accompanying drawing preferred embodiment of the present utility model is described.
In the present embodiment, the continuous cast mold vibrating device mainly comprises pedestal 1, electromagnetic exciter 2a and 2b, damper 3a and 3b and spring 4a and 4b.As shown in Figure 1, 2, electromagnetic exciter 2a and 2b are installed in the surface of pedestal 1, its vibrating elements (being vibrative part among electromagnetic exciter 2a and the 2b) is rigidly connected with continuous cast mold 5 and move perpendicular to pedestal 1 surface direction in the edge, so continuous cast mold 5 will vibrate with the vibrating elements of electromagnetic exciter 2a and 2b.Damper 3a and 3b are connected between pedestal 1 and the continuous cast mold 5, and spring 4a and 4b also are connected between pedestal 1 and the continuous cast mold 5.
Fig. 3 is the mechanical model of above-mentioned continuous cast mold vibrating device.In this model, the vibrating object that it is m that the part that comprises electromagnetic exciter 2a and 2b, continuous cast mold crystallizer 5 and strand generation vibration is equivalent to a quality, the equivalent spring that it is k that spring 3a and 3b are equivalent to a rigidity, the equivalent damping device that it is c that damper 4a and 4b are equivalent to a damped coefficient.When vibrating object was in the equilbrium position, because the effect of gravity, there was an initial deformation mg/k in equivalent spring; When electromagnetic exciter 2a and 2b work, vibrating object m is by certain frequency and near the amplitude up-down vibration equilbrium position, and its frequency equals to drive the sinusoidal drive power frequencies omega of electromagnetic exciter 2a and 2b, and amplitude then depends on sinusoidal drive power frequencies omega, amplitude F
0, parameters such as the rigidity k of vibrating object quality m, equivalent spring and damped coefficient c, therefore by selecting suitable parameters just can make vibrating object, even also continuous cast mold 5 is with required frequency and amplitude vibration with required frequency and amplitude vibration.
