Definitions
- the invention relates to a short, water-cooled, below open mold for making blocks or strands according to the preamble of claim 1. Also recorded the invention a device with such a mold for the continuous casting of metals and a method for Electroslag remelting.
- the one in electro-slag remelting for special process variants used so-called stand molds should not be here to be viewed as.
- molds of interest here enable this Making strands or blocks that last considerably longer are as the water-cooled molds, with the conventional Continuous casting the strand formed in the mold subtracted either vertically or in an arc becomes.
- electroslag When electroslag is remelted, it can be in the mold formed block either by lowering a bottom plate subtracted down, or it can be Chill mold can be lifted in the way that on a fixed base plate a remelting block is built.
- Electroslag remelting largely solved, since here the liquid metal sump is covered by a slag bath and is protected from direct air access. The The electrode tip also melts within of the slag bath so that direct contact of the liquid metal with the surrounding atmosphere avoided becomes.
- the continuous casting was initially done in air, trying was, by adding oil in the area of the pouring level to limit the oxidation of the metal.
- the Introduction of mold powder to cover the mold level and the use of dip tubes for the supply of the liquid Metal in the mold has further improvements here guided.
- DE-A-1 483 646 describes a method for producing Cast blocks described with directional solidification, at which the surface of the melting sump by an overlying Slag layer is kept warm; the latter is produced in a predetermined area of the mold is connected to a power source.
- the slag bath is heated by the current transfer between two poles, one of them through the slag bath / smelter interface as well as the other from one into that Slag bath immersed - and also to that power source connected - power supply electrode formed becomes.
- That electrode is otherwise not identical to that metal forming the ingot; it is either as separate supply element on the slag layer set or attached to the top of the mold wall; an insulating intermediate piece is imperative in it Ceramic between the electrode and the mold required to avoid an otherwise occurring short circuit prevent.
- the second pole can also be from one directed towards the slag bath charge carrier beam a source that is not immersed in the slag bath be formed. That which solidifies in the mold Metal can be extracted from a slag bath as liquid metal Pouring ladle, as granules from a container or in form be fed to a self-consuming electrode.
- GB-A-1 413 508 discloses a mold in its mold wall installed a non-consumable current-carrying element as well as via a rectifier with the power supply is connected that both the electrode and the Pouring cross section - in relation to the non-edible element - are always electrically negatively polarized.
- US-A-3 768 543 is used to manufacture metal blocks from small pieces of metal particles in one several parts of existing water-cooled mold a meltable one between two water-cooled elements Metal electrode installed so that it is partially through the Cooling effect of these elements protected and with one pole is connected to a power source.
- One below the meltable electrode arranged mold element jumps inside in front.
- the Electricity flows here between the partial melting electrode in the mold wall and the Block.
- a system and a method according to DE 2 620 823 are intended in particular for the production of narrow slabs i.e. rectangular block formats, can be useful, whereby among other things consumable used, their cross-sectional area 1.05 to 20 times the cross-sectional area of the produced Blocks is.
- a slag bath is formed in the mold, in which both Immerse consumable and non-consumable electrodes.
- electrodes their cross-sectional area larger than the cross-sectional area of the manufactured Blocks is, molds are expanded funnel-shaped upwards used.
- auxiliary electrodes discussed here have the disadvantage that they are not an integrated part of the mold wall and only partially immerse in the slag bath. Above of the hot slag are auxiliary electrodes on almost Heated slag temperature and in contact with the ambient air oxidized very quickly, leaving only an insufficient Durability is achieved.
- the water-cooled copper elements Mold wall formed at least one not directly water-cooled current-carrying element installed so that this in a region which determines the position of the slag bath (20) is therefore in contact with the slag bath, and also completely below the surface of the slag bath is arranged, but not up to the mirror of the liquid metal is enough; over this element is a Contact can be made to a power source that according to Claim 1 on the other hand to an edible electrode or the resulting block or the one bearing it Base plate is connected.
- these current-conducting elements preferably uses graphite in a manner known per se, but also high-melting metals, such as Tungsten, molybdenum or the like are suitable.
- the upper part of the Chill mold that receives the slag bath and into which current-carrying element (s) is / are installed funnel-shaped be expanded. This may be particularly true in manufacturing of strands of small cross-section with a diameter or a side length of less than 300 mm of interest his.
- a further embodiment of the mold according to the invention provides that the built-in current-conducting element (s) is / are electrically insulated from the copper part of the mold by installing non-conductive elements.
- Refractory ceramic materials such as fireclay, Al 2 O 3 , MgO etc. come into consideration as the material for the non-conductive elements.
- the mold according to the invention enables a number of different arrangements and process variants with electroslag remelting or with Continuous casting, the most important of which are described below become.
- Fig. 1 shows the schematic structure of a tubular Mold 10 for so-called electro-slag remelting (ESU).
- ESU electro-slag remelting
- a remelting block 16 is formed and so deducted from the mold 10 that the meniscus one liquid sump 18 in that lower water-cooled Mold part 12 is located.
- a liquid To recognize slag bath 20 in which an edible Electrode 22 is immersed.
- the inflows of the mold parts 12, 14 for the cooling water are designated 28 for the sake of clarity Drains with 30.
- the mold 10 described above is also suitable for continuous casting, as shown in FIG. 2. Again, the meniscus of the liquid Bottom 18 of the strand 32 withdrawn from the mold 10 covered by the liquid slag bath 20, which in the Area of the not directly cooled current-conducting element 24 and the - also not directly cooled - not current-conducting elements 26 is held. That all in one liquid widening upward intermediate vessel 34 Metal 36 arrives in the flow direction x via an immersion tube 38 as a pouring jet 40 directly into the liquid sump 18.
- Fig. 3 offers the schematic structure of an ESCU system Sliding mold using the one shown in Fig. 1 Mold 10 on.
- the installation of a current-carrying element 24 in the area of the slag bath 20 enables a number of Variants for connecting the system to a power source 42 for alternating or direct current through corresponding Switching switches 44, 46, 48, 50 can be achieved can.
- a current flow like that of conventional electroslag remelting is common arises when the switches 44 - in line 45 between current source 42 and electrode 22 - and switch 48 - in line 49 between current source 42 and a base plate 52 - are closed when open Switch 46; the latter is the current-carrying element 24 assigned.
- Switching point 48 is with Line 49 connected.
- FIG. 4 shows an embodiment of the mold 10 according to the invention, in which two current-conducting elements 24 a and 24 b are insulated from the lower water-cooled mold part 12 and the upper water-cooled mold part 14 by non-current-conducting elements 26 and horizontally from one another by likewise non-current-conducting intermediate elements 58 are.
- two current-conducting elements 24 a and 24 b are insulated from the lower water-cooled mold part 12 and the upper water-cooled mold part 14 by non-current-conducting elements 26 and horizontally from one another by likewise non-current-conducting intermediate elements 58 are.
- the current flows through the slag bath 20 between the two current-conducting parts 24 a , 24 b .
