Description
The present invention relates to a kind of oscillation mould support with fixing stand and in pairs stacked jib, the bearing support that the supporting crystallizer is used is housed on described stand, described jib is hinged and hinged with bearing support on the other hand with stand on the one hand.
In continuous casting installation for casting, crystallizer and vibration thereof are prominent especially.Meanwhile, the guider during elevating movement is determining the number of times that breaks greatly that expends at work to a great extent.Realized the following vibration form of the composition up to now:
-having a spring guide type vibrating device of four eccentric driving devices: oscillation mould is suspended in the framework of fixed-site and and then is seamlessly guided by four reeds.Crystallizer Maintenance free and seamlessly being guided in vertical direction.The shortcoming of this vibrating device is only vertically to guide crystallizer on its track.Must guarantee the guiding relevant by the oscillation drive on all four angles of crystallizer with its support.For example need two to have two eccentric eccentric shafts respectively for this reason.
-have two eccentric short lever vibrating devices: vertically guide crystallizer by two parallel guide rods.Driving realizes that by a lever described lever has prolonged the lower crank swing-bar mechanism on fixed piovt point.The vertical displacement movement of crystallizer not only has been subjected to guiding in track but also in support.The defective of this vibrating device is that supporting base must bear the double heavy burden of crystallizer.Supporting base not only must bear guiding force, and must bear lifting power.This causes bigger maintenance work cost and repair work cost.
-have the parallel conductive rod-type vibrating device of two hydraulic cylinders: by two parallel guide rod vertical guide crystallizers.The introducing of lifting power is directly to realize below crystallizer.The vertical displacement movement of crystallizer not only has been subjected to guiding in track but also in support.The shortcoming of this vibrating device is that the rotation in support can only have the several years.Must make expensive supporting structure also safeguards it for this reason at work.Support must not be subjected to the influence of cooling water and must be lubricated by the grease lubrication centring system.The support gap can not be cancelled by balance.
-resonance crystallizer: in framework, pass through two reeds from each side directed crystallizer.Reed is by its elastic force supporting crystallizer.Crystallizer has gapless suspension and need not a large amount of supporting structures of safeguarding.The guiding of the crystallizer in track and support is perfect.The shortcoming of this crystallizer is that by very big influence, this is because coefficient of elasticity must be very big so that the supporting crystallizer to spring to vibration mode.Under the simplest situation, can under spring/quality system eigentone, implement the sinusoidal vibration mode.Limited guiding to crystallizer can only realize by the reed of a high rigidity.When vibration frequency changes, very big or uncontrollable reaction force may appear, and such reaction force makes system bear overload.
-having the spring guide type vibrating device of hydraulic drive mechanism: oscillation mould is placed on the crystalliser.Similarly pass through two reeds from each side directed this framework with above-mentioned resonance crystallizer.The coefficient of elasticity of reed is low and do not have a rigidity.Therefore, must in support, force the guiding crystallizer.Crystallizer need not maintenance and seamlessly is subjected to vertical guide.Can control different lifting forms by hydraulic drive mechanism.The shortcoming of this vibrating device is, can only be on its track the vertical guide crystallizer.Must guarantee the guiding relevant by the vibratory drive mechanism on all four angles of crystallizer with its support.This is guaranteed by four hydraulic cylinders.Meanwhile, must so constitute hydraulic cylinder control mechanism, all four hydraulic cylinders of machine must the work of absolute synchronization ground.Required for this reason mechanical technique cost is than higher.

EP0150357 has described a kind of guider of vibratory drive formula continuous cast mold, and wherein the anchor clamps that link to each other with framework by spring part respectively are fixed on the crystallizer lifting platform.On its central area is anchored at spring base on the framework, a reed has been installed with intervally and this leaf end is fixed on the described spring base.The crystallizer lifting platform links to each other with reed by a middleware that is fixed on the reed mid point.
DE-OS2248066 discloses the device that another kind of guiding oscillatory type continuous cast mold is used.In this guider, crystallizer is fixed on the spring part, and the relative direction of vibration of described spring part laterally is fixed on the support.This spring part is at one end clamped with cantilevered fashion, and wherein crystallizer is fixed on the free end.Spring part method by this way is designed to multiple field reed group, and promptly corresponding with crystallizer weight degree of flexibility equals the Oscillation Amplitude of crystallizer at least.
From above-mentioned prior art, task of the present invention is to propose a kind of new crystallizer hanging method, it especially guaranteed pin joint after long-term work still very close to each other and therewith about realized no maintainability and the no abrasiveness of hinge, the method intrinsic vibration that relevant ground with spring/quality system does not obviously expose when processing the crystallizer suspension the most cheaply and can realize guiding the most cheaply to oscillating mass.
In order to finish above-mentioned task, a kind of oscillation mould support of the present invention with fixing stand and in pairs stacked jib, the bearing support that the supporting crystallizer is used is housed on stand, jib is hinged and hinged with bearing support on the other hand with stand on the one hand, jib links to each other with bearing support with stand by hinges, and wherein said hinge is designed to the reed-type hinge.
The constituted mode of support of the present invention advantageously makes following positive performance become possibility:
The no maintainability of-hinge;
The no abrasiveness of-hinge;
-make the reed-type syndeton the most cheaply;
-two hydraulic cylinders just are enough to be used in driving, and promptly need not to make the hydraulic system of four hydraulic cylinder synchronous;
-supporting base needn't bear double load because of disadvantageous lever ratio;
-spring does not have the task of equilibrium crystallization device and vibration frequency or vibration processes is not influenced the intrinsic vibration that spring/quality system does not obviously expose here.
