Definitions
- the invention relates to a mold for continuous steel casting according to the preamble of claim 1.
- tubular molds are used almost exclusively, the mold cavity of which is defined by a mold tube.
- Such mold tubes usually consist of a tube made of copper or a copper alloy with a wall thickness of 8-25 mm, which is produced by a large number of expensive operations.
- Chill pipes made of copper or a copper alloy are usually cold drawn in order to achieve a solidification which gives the chilled pipe the required strength.
- the mold tube is provided with a casting cone in the mold cavity and is provided on the outside with a smooth wall or with smooth walls. In many cases, the mold cavity is provided with electroplated coatings made of chrome and nickel.
- water is pumped at high speed, e.g. at 6 - 14 m / s, pressed through in a water gap on the outside of the copper pipe.
- a water gap with a regular water gap width is required for uniform cooling of the copper pipe.
- the water gap is determined on the one hand by the outer dimension of the copper pipe and on the other hand by a water jacket matched to this outer dimension.
- the copper pipes represent wear parts that have to be replaced after 120 - 200 castings due to scratches, warpage, etc.
- Various methods have become known for increasing the economic efficiency, all of which aim to supply such expensive copper pipes to a second and possibly third use.
- the wear pattern of such molds is generally characterized by warping and cracking in the area of the bathroom mirror, caused by the high thermal stress, and by abrasive wear and scratches in the lower mold half. If such defects in the mold cavity are removed by machining, the mold cavity is enlarged and the cross-sectional dimension of the cast strands becomes larger. In order to avoid such enlargements of the strand cross-section, the explosion deformation of mold tubes on a mandrel matched to the mold cavity dimensions has become known. Other pressing methods for reshaping the expanded tubes have also become known. All of these reforming methods, such as explosion or press recalibration, have the common disadvantage of a reduction in the outer cross section of the mold tube. This reduction in cross-section increases the water gap between the mold tube and the water jacket in an uncontrolled manner, which in turn has an adverse effect on the cooling of the mold.
- the invention has for its object to eliminate the disadvantages described in the prior art and in particular to redesign the mold structure for tubular molds in such a way that the costly production of billet and pre-block molds with cold-drawn tubes made of copper or copper alloys can be avoided. Another goal is seen in a mold construction that has a significantly longer service life and can be brought back to the desired dimensions in the area of the mold cavity by recalibration.
- the mold according to the invention it is possible to overcome the disadvantages of tubular molds described in the prior art and to avoid the costly production of billet and bloom blocks from cold drawn copper pipes.
- the coating is renewable, it is possible to re-coat the coating carrier as often as desired without changing casting parameters such as strand format or water gap.
- the heat output of the mold can be easily adapted to specific needs.
- the coating which is applied as a thick layer and brought to the desired cavity dimension with a preferably machining operation, can also, with regard to cooling capacity and, if desired, also with regard to wear, the specific requirements for continuous casting as a function of the continuous casting parameters, for example the casting temperature or the steel composition.
- the coating has adequate heat resistance at the casting temperature.
- the mold tube has to ensure high heat output on the one hand and the required stability on the other.
- the service life during casting is regarded as a measure of the stability. At least two factors contribute to the stability of a mold tube.
- the stability of a mold tube is determined on the one hand by its ability to withstand the high thermal load in the casting operation, caused by contact with a melt on the inside and simultaneous intensive cooling on the outside.
- the stability of a mold tube is also determined by its ability to withstand the mechanical stresses in the casting operation.
- the coating carrier can be designed in such a way that it ensures a high mechanical strength of the inner body and thus ensures the desired stability of the inner body, while the coating can be suitably selected with regard to the thermal properties and the thickness in order to dissipate the heat of the inner body to optimize.
- a coating carrier which is made of a material with increased mechanical strength, can have a reduced wall thickness and therefore allow an increase in the heat output of the mold. Provided that the coating is renewable, repeated repairs can result in a significantly longer service life for the mold.
- the coating carrier from aluminum or an aluminum alloy, for example from the alloy AlMgSil known as Anticorodal WN 6082.
- Aluminum or aluminum Alloys have a thermal conductivity in the range of 130 - 220 W / mK. Since the coating carrier in the casting operation is always at a finite distance, given by the thickness of the coating, from a melt introduced into the mold cavity and the inner body is also cooled, a coating carrier made of aluminum or an aluminum alloy can be used in the casting operation are kept at a temperature at which aluminum or aluminum alloys have a particularly high strength. Solidified molded parts made of aluminum or an aluminum alloy can also be produced relatively inexpensively, for example by extrusion.
- the coating can be varied to meet the specific requirements of continuous casting in the longitudinal direction of the mold and can also be adapted to different types of steel to be cast.
- a highly thermally conductive material for example copper or a copper alloy with a thermal conductivity of 200-400 W / mK, is preferably selected at least in the area close to the bath level.
- the coating is designed as a thick layer with a thickness of 0.5-5 mm, preferably 1-4 mm.
- a coating can be produced galvanically or by plating or by means of thermal spraying, for example flame spraying or plasma spraying, and can be provided with a surface by machining which corresponds to the desired shape of the mold cavity with the required accuracy.
- the mold described in the prior art can be reached, even if the thermal conductivity of the coating carrier is lower than the thermal conductivity of the coating.
- the wall thicknesses that determine the heat transfer, in particular of the coating carrier, can be made relatively thin.
- the coating carrier can be provided with cooling ribs on the side facing away from the mold cavity.
- a distance between the cooling fins of, for example, 5-8 mm can be selected to set the cooling parameters.
- the wall thickness of the coating carrier between the cooling fins can be 2-10 mm, preferably 5-8 mm.
- a coating carrier with such thin wall thicknesses, together with a copper coating of, for example, 3 mm, ensures a high thermal output.
- the coating carrier is produced from a pressable aluminum alloy with corresponding cooling fins in a press operation. It is also possible to assemble the coating carrier from several parts and then to coat the inside.
- Coating supports for molds with a polygonal mold cavity cross section can be composed, for example, of several flat or curved plates, each of which forms one of the side walls of the mold that delimit the mold cavity
- the different materials from the classic tubular mold give the mold according to the invention, with an optimal choice of the wall thickness of the coating carrier and the thickness of the coating, a number of properties which can be used with advantage with regard to the casting operation and the construction of casting systems.
- the mold according to the invention has advantages with regard to the use of an electromagnetic stirrer on the outside of the coating carrier. With an optimal choice of material for the coating carrier, in comparison to known molds, an identical stirrer can achieve an increased stirring performance or a less powerful stirrer can be used to achieve the same stirring effect. Compared with copper or copper alloys, aluminum or aluminum alloys lead to a considerably lower attenuation of the electromagnetic field generated by an electromagnetic stirrer.
- the mold according to the invention is relatively light in comparison to a corresponding mold made of copper or a copper alloy. Because of the lower weight, the mold oscillation required in the casting operation in the mold according to the invention can be carried out with simplified means in comparison with a corresponding mold made of copper or a copper alloy. The lower weight generally leads to easier handling of the mold according to the invention, in particular when replacing or installing and removing and when transporting the mold. All of the measures associated with transporting the mold can be carried out using simplified means.
- the mold according to the invention therefore has an increased transparency for radioactive radiation in comparison to a comparable mold made of copper or a copper alloy.
- This property of the mold according to the invention can advantageously be used with regard to the design of devices for measuring the level of the bath level of a melt introduced into the mold cavity of the mold.
- the level of the bath level of a melt is usually determined with the aid of a measurement of the transmission of radioactive radiation through the walls of the mold transversely to the casting direction.
- the mold according to the invention allows such transmission measurements to be carried out with increased sensitivity and, optionally, to work with weaker radioactive radiation sources and / or a simpler measurement technique.
- Fig. 2 is a horizontal section through the mold along the line l-l of Fig. 1 and
- Fig. 3 is a vertical section through another example of a mold.
- FIG. 1 and 2 schematically show a billet or bloom block 3 with a mold cavity 4 for the continuous casting of steel.
- Such molds are cooled intensively with a cooling medium, preferably cooling water.
- a coating carrier 6 has a highly thermally conductive, renewable coating 7 made of copper or a copper alloy with a thermal conductivity of 200-400 W / mK on the mold cavity side.
- This loading Layering 7 can be applied galvanically to the coating carrier 6. However, it can also be applied by thermal spraying, for example flame or plasma spraying, or by plating.
- the mold cavity 4 is brought to the desired mold cavity dimension and the desired mold cavity surface quality by machining. All methods known in the prior art can be used for machining the mold cavity surface, in particular machining operations such as milling, grinding, spark erosion or machining with laser beams are suitable.
- a lower and an upper mold end cover are shown with 10, 10 '.
- the choice of material for the coating carrier 6 is geared firstly to the stability to fulfill the supporting function and to good dimensional stability at elevated temperature.
- the strength of the coating carrier 6 should be higher than that of the coating at the temperatures achieved in the casting operation.
- Aluminum or aluminum alloys are suitable as materials for the coating substrate. In the production of a coating carrier 6, for example, the excellent properties of aluminum and aluminum alloys during pressing can also be decisive.
- Coating carriers 6 composed of several parts can also be used without disadvantages because the coating in the mold cavity seamlessly covers the seams between the individual parts.
- the coating carrier can, for example, be constructed from several parts which are held together by welding, with the aid of suitable fastening means such as screws or rivets or in some other way.
- the coating carrier 6 is provided with cooling ribs 11 on the side facing away from the mold cavity 4.
- the distances between the cooling fins 11 are 5 to 8 mm.
- the wall thickness 12 of the coating carrier 6 between the cooling fins 11 can also be dimensioned thin with 2-10 mm, preferably 5-8 mm.
- a mold 20 with, for example, a square cross section is provided with a stirring device 21.
- the stirring device 21 can be brought closer to the mold cavity 22 due to the different structure of the mold compared to classic tubular molds.
- the material for to optimize the coating carrier 23 and for the jacket 24 with regard to the requirements for the operation of the electromagnetic stirring device 21.
- the strength of the electromagnetic field generated by the stirring device 21 in the mold cavity 22 can be maximized by a suitable specification for the electrical conductivity of the coating carrier 23.
- the use of aluminum or an aluminum alloy has advantages because of the relatively low electrical conductivity of these materials.
- a coating 26 made of a highly thermally conductive material is applied in the bath level region 25 or in the upper mold half and a coating 28 made of a material which is harder than copper, for example nickel, is applied in the lower part or the lower mold cavity half.
- Lubricants are embedded in the coatings 26 and 28 for the lubrication of a strand crust.
- Molybdenum and / or tungsten-based lubricants preferably M0S2 and / or WS2
- Other lubricants known in the prior art that can be stored in coatings are also included in the sense of the invention.
- FIGS. 1-3 only straight molds are shown. However, the invention is not restricted to such molds with a straight mold cavity. All molds for the continuous casting of billets and blooms that have a tubular coating support fall under the subject of the invention.
- the geometry of the mold cavity can be chosen arbitrarily.
- measuring probes for example temperature sensors
- the measuring probes to be embedded can be applied before the coating is applied are arranged with great accuracy on or near the surface of the coating carrier to be coated and are coated with the material forming the coating when the coating is applied.
- the measuring probes can be arranged within the coating without having to rely on producing holes after application of the coating which end in the coating and are suitable for receiving the measuring probes.
- the positioning of measuring probes in boreholes can only be checked relatively imprecisely. Such inaccuracies, which cause inaccuracies in measurements using the measuring probes, are avoided if the measuring probes - as described above - are embedded in the coating during the production of the coating.
- Aluminum is a relatively base metal. Parts made of aluminum or an aluminum alloy therefore tend to corrode when they are connected to other metals by an electrolyte.
- the corrosion resistance of the coating support of the mold according to the invention can be achieved by known means, for example by applying suitable protective layers at exposed locations.
