The invention relates to a method and a device for producing metal pieces with a predefined size from the liquid phase, more particularly pieces made of ferro-alloys or non-ferrous metals, comprising a strip casting facility that produces a continuos metal strip having a predetermined thickness and a breaking facility that fragments the strip into pieces. During casting and solidification, a pattern of breaking points is engraved on the surface of the strip using an embossing roller (1), said pattern determining the predefined optimal size of the pieces after the band has been fragmented.
Description
Technical field
The present invention relates to be used for the casting of liquid metal and particularly ferroalloy or non-ferrous metal and solidify and broken method and apparatus.
Background technology
People need a kind of method and corresponding device thereof of fast and flexible, described method and device are used for the casting of liquid metal and particularly ferroalloy or non-ferrous metal and solidify and fragmentation in good order, its objective is and to pollute the workpiece of producing the size conforms regulation under minimum and the situation about reducing energy consumption and production costs in loss.
In the prior art, ferroalloy or non-ferrous metal usually from come out of the stove the back casting bed, cast under the liquid state and solidifying and cooling off after be sent to disintegrating machine, be broken there and be classified and wire up by commercial granularity subsequently.
According to first known method (method 1), quantity can reach 25% the granule of crossing and melt down again and melted.The deficiency and the shortcoming of method 1 are as follows:
1. in broken and screening installation zone, the energy, production cost and maintenance cost are all very high;
2. the product recovery rate is higher and low because of crossing small particle content;
3. high dust load and noise burden requirement are used for the great amount of investment and the measure of dedusting and noise control;
4. sand and tapping floor are the first causes that causes contamination of products;
5. Fu Za rear supply;
6. the granule of crossing that additional fusing is screened causes the product cost burden heavy.
Another known method (method 2) regulation is cast into ingot with casting wheel with liquid metal, so that obtain needed granularity by broken and screening subsequently.The deficiency and the shortcoming of method 2 are as follows:
2. the output of casting wheel is limited and dumb, this require long casting time and and then the tapping temperature of having relatively high expectations, and this causes extra energy consumption and refractory material expense or shorter stove service life.
3. ladle economy causes high cost,
4. the influence to the workpiece size size can only could realize by regulating screening installation, but is not in casting cycle.
US 4,316,496 and corresponding D E-OS3028247 disclose and be used to produce the raw-material square law device of iron, this iron raw material are used in melting kettle or the smelting furnace subsequently.
This device demonstrates the girder steel that a cross section takes the shape of the letter U, but this girder steel along continuous straight runs is supporting movably and the other process at a casting station continuously, here, in casting station, be provided with and be used for the molten iron material constantly is cast to device on the girder steel, solidify sheet iron strip so that after cooling, form.In addition, be provided with and will solidify the device that band is cut into fragment, the fragment size is suitable for use as the irony raw material.The thickness of girder steel should make the heat radiation of casting band enough, thereby promotes that band solidifies.
Steel beam surface has the protuberance of a series of pitch arrangement in accordance with regulations.But also can dispose a roller, this roller has the surface of a band groove and is positioned on the girder steel in downstream, casting station, here, there is certain distance this roller and metal surface, and this segment distance is enough to keep this roller to contact and when band hardens gravure is printed in the band thus with the casting band.
Make the irony raw material and the year after its is supplied with in the method for smelting furnace, the iron material of continuous smelting is cast on the surface of a U flute profile girder steel from the casting station, this steel beam surface is passed through on next door, casting station on a horizontal plane continuously, so that form a frozen metal band, here, solidify band and separate with girder steel and be fractured into fritter under hardening state, the size of fritter is suitable for makes required raw material.
Summary of the invention
From above-mentioned prior art, task of the present invention is to propose a kind of method and a kind of device, and by this method and apparatus, elimination can foregoing shortcoming and difficulty.
The solution of above-mentioned task is to adopt the method for claim 1 to realize, this method is used for by using a tape casting equipment and a disintegrating machine to make metal derby by the ferroalloy or the non-ferrous metal of liquid state, continuous band and this disintegrating machine that this casting equipment manufacturing one has predetermined thickness are broken into fritter with this band, wherein in the process of casting and solidifying, impress out the figure of theoretical break-up point on strip surface, this figure has determined the predetermined optimum size of product spare when broken band.
An embodiment regulation of the inventive method, the figure of theoretical break-up point is for example made by some shaped pieces are welded on the roller platen.
In addition, can advantageously utilize following measure, promptly the figure of theoretical break-up point is made by such some parts, promptly these parts have be different from the roller platen material physical property as higher thermal conductivity.
In addition, the inventive method is characterised in that, casting rate (Vg) and the position and the distance that have a roller platen of coining pattern are controlled according to the described formula of claim 4 and according to following parameter by a control system, performance, its tapping temperature and the desired thickness (d) of the product of promptly waiting to cast, have the diameter (D) of the roller platen of coining pattern.
The roller platen that cooling has coining pattern is favourable.
Be used to control the method for making the production technology of metal derby by the especially ferroalloy or the non-ferrous metal of liquid state and advantageously grasp metal temperature and casting rate by sensor, tape casting equipment and a disintegrating machine that is used for this band is broken into the fritter of preliminary dimension that is used to produce the continuous band with predetermined thickness adopted in this manufacturing, wherein data be transfused to a control system as a computer so that carrying out data handles, regulate position, rotating speed and the depth of indentation of roller platen (or a plurality of roller platen) by this computer.
Device that be used for making metal derby by liquid metal and especially ferroalloy or non-ferrous metal and that be used to implement the inventive method comprises that a tape casting equipment that is used to produce the band with predetermined thickness and one are used for the kibbled disintegrating machine of band, wherein for example in a single belt band casting equipment, also be provided with some roller platens, they are used for impressing out the figure of theoretical break-up point when band is cast and solidified.
According to other embodiment of device of the present invention as the dependent claims regulation.
Description of drawings
Details of the present invention, feature and advantage can obtain from following description to the embodiment shown in the accompanying drawing signal.Accompanying drawing is represented:
Fig. 1 is the side view of apparatus of the present invention;
