Abstract
A crystallizer apparatus for producing conticast metal blanks, especailly steel blank, has a copper plate as wider sides of crystallizer, which are borne on coolable supporting plate. It also has narrow sides between the wider sides and oscillator fixed to the supporting plate. The supporting plate has a trough-shaped part in the wider side region of crystallizer. A channel for cooling medium is made on the wall of trough-shaped supporting plate. The electromagnetic members arranged on supporting stand can be freely put in free trough cavity whose mouth is far from the wider side.
Description
The present invention relates to the mould assembly of a kind of production continuous casting of metals base (particularly steel billet), this device has the copper coin as the crystallizer broad side surface, and this broad side surface is bearing on the coolable support plate.This device also has the narrow side and an oscillator that is fixed on this support plate that can be clipped between this broad side surface.
In order in producing the continuous cast mold of continuous casting steel billet, to obtain high-quality steel billet, use magnetic stirrer or brake and make the molten steel molten bath obtain agitation as appropriate.When using agitator,, thereby under the situation that field trash fully precipitates, obtain most coaxial crystal grain by agitation as appropriate to the molten steel molten bath.Using brake is in order to utilize Lorentz force, and Lorentz force is accelerated the motlten metal flow velocity that comes out from the immersion delivery port, has reduced the molten metal surface wave amplitude thus.
Drive unit and suspension arrangement for strand can use different version.DE-40 23 672 A1 files have disclosed a kind of liquid-cooling type crystallizer that is used for continuous casting of metals, and wherein, except original crystallizer, an oscillator promotes copper coin and corresponding support plate and the adjusting mobile device that is used for narrow side.For hang this support plate, be provided be fixed on one with base plate that the pedestal of a fixed-site links to each other on spring part.The disclosed mould assembly of this part data does not have calutron.
DE 31 12 930 C2 disclose a kind of continuous cast mold that has the stirring coil that is used for rectangular casting blank, in this crystallizer, four support plates are clamped together, and two longerons that clamped by turnbuckle remain under the assembled state these support plates, on this support plate agitator are arranged.
The structure of support plate and coil is connected makes stirring coil or a kind of brake of selecting to install must mobile together in disadvantageous operating process by the oscillator band.
The disclosed magnetic stirrer of DE 31 06 591 A1 also is this situation.In the agitator that designs for the continuous casting steel billet crystallizer, an agitator coil chamber is installed on the top of cooler bin.In a design of this agitator, stirring coil can freely be put into the cooler bin of fixed head one and from wherein taking out.At this, this fixed head is used as the lid of the opening of sealing stirring coil chamber, and constitutes its rear wall simultaneously.
This structure of teeter chamber makes when changing cooling piece, always must remove stirring coil, and this is not only expensive but also time-consuming.
The objective of the invention is to, provide a kind of as claim 1 mould assembly as described in the preamble, it has a kind of compactness and on-deformable structure, and changes easily, can use a kind of electromagnetic structure spare under the situation that does not increase the quality that is moved by oscillator.
Finish above-mentioned task by the technical characterictic that the characteristic of claim 1 is pointed out.Dependent claims has been pointed out other favourable structures of mould assembly.
According to the present invention, this support plate is a flute profile.Because this shape, not only make the support plate of the copper broad side surface of supporting crystallizer that very high rigidity is arranged, except guaranteeing guiding, also form a kind of space that can freely utilize in addition to cooling fluid, magnetic stirrer or brake can be put into above-mentioned space.
When using coil, this flute profile makes the center cross-sectional of the close strand of coil and is in a kind of position that can obtain maximum electromagnetic penetration effect.Because stirring on the support of mould assembly trembled this set of device, makes the quality of oscillating movement can not increase.
In addition, also have a kind of like this possibility, promptly no matter how many oscillating mass of crystallizer is, calutron moves perpendicular to the steel billet direction of transfer.Like this, can unclamp support plate and it is taken off from crystallizer with the simplest method.In addition, under the situation that is with or without agitator or brake, also can resemble hope operate this device, and do not spend extra cost.
Even in addition, under the situation that does not influence oscillating mass, calutron can be parallel to the strand direction of transfer and move, thereby at work, also can carry out the best adjustment to agitator or brake.
By in the recessed bearing, plate, forming passage, can carry out motivated control to the guiding of cooling medium, and the heat that obtains thus to determine scatters and disappears.
The characteristics of support plate bathtub construction are extra high rigidity.In order further to improve rigidity, dividing plate or fin are set in the groove cavity.
Have on one in the design that is bearing in the flange on the bearing support, support plate has the advantage that can especially easily fit together.Therefore, not only shortened built-up time, can also assemble crystallizer in advance with straightforward procedure.
Because calutron and crystallizer oscillating component structurally separate, therefore, because from outside to inside free access is arranged, so can easily carry out Height Adjustment to calutron and crystallizer oscillating component.In addition, each strand only needs a coil or brake, even this is because when changing support plate, coil or brake are also stayed in the device.In known devices, under any circumstance, removable support plate all remains with a calutron.
By the fixing calutron of a simple mode, promptly by utilizing a drive unit magnetic core to be shifted onto the mode of bottom land as stirring coil.In addition, the coil of wounded core is together to support plate direction motion and be blocked before rib outside support plate.In order to ensure its fixed-site, magnetic core is clamped.
Each magnetic core all is bearing on the common bobbin, circularizes and around the support plate setting at this bobbin.
Each support plate has the flange that is bearing on the fixed mount respectively at head.These fixed mounts structurally are so designs, and they have narrow side mobile device, and can not cause under the situation of any overslaugh, and they can be moved out from device together with the support plate of simple mode and its supporting.
In a favourable mode, fixed mount is useful on inlet opening or apopore is connected to water pipe on the support plate.Simultaneously, between support plate and fixed mount, elastic component is set, the position of this elastic component between can the horizontal adjusting broad side surface, but guiding that can overslaugh water.
In addition, described fixed mount is so design structurally, this fixed mount fixed support plate, and can allowing to each other, horizontal fixed connects.
