Definitions
- the invention relates to a continuous casting mold for casting strands, preferably made of steel, consisting of mold plates and water box, which together are connected and between which water cooling with the help of Water channels are built, the water channels in the Chill plate facing side of the water tank are arranged and not in the mold plate.
- Mold plates - preferably consisting of copper for the continuous casting of Slabs, thin slabs, blooms and profiles - are on their back cooled with water and screwed onto a steel water tank.
- the water is directed vertically to the upper edge of the mold through channels 5 mm wide from the mold exit (bottom) in the direction of the casting level.
- the water is conducted at a pressure between 5 to 15 bar and flow velocities of 5 to 15 m / s through the water guide channels to the heat flow of up to 4 MW / m 2 at the phase boundary Cu plate / water without disturbing the heat transfer To be able to absorb and remove gas bubbles.
- a mold plate for continuous Casting strands of steel shown.
- the mold plate is built in sandwich construction, consisting of the leading the casting strand Copper plate connected to a support plate via a screw connection stands.
- Water guide channels are arranged in the support plate.
- For the purpose of Connection of the copper plate to the support plate are on the side facing the support plate Side of the copper plate provided thickenings, which in corresponding Intervene in the support plate. Be in these thickenings Screws screwed in to secure the copper plate and support plate together connect.
- the water channels are arranged in the support plate and not in the copper plate.
- a copper plate is used shown in sandwich design. There is a copper plate on a steel plate, on which the casting strand is guided. In the steel plate and not in the Cooling channels are embedded in the copper plate. The cooling channels are from the copper plate covered and the connection between steel plate and copper plate is produced by means of a screw connection. Sealing between the steel plate and the copper plate is made using soft solder.
- the invention is characterized by a design of the continuous casting mold, at that of the water box and the connecting plate of the water box with the help of Screws that are embedded in the mold plate and by means of the water tank arranged nuts are joined together and in which the connecting screws are provided with internal or external cooling channels, which with the water channels are connected.
- FIG. 1 shows a horizontal section through the broad side 1 of a thin slab mold with pouring funnel 2 or with a liquid steel facing concave mold shape.
- the water tank 6 consists of a steel plate 9 with the water guide channels 7, a wall thickness or comb thickness 7.1 and a channel width 7.2 and the actual water guide box with its webs 10.
- the webs 10 can either be welded 11 to the steel plate 9 or e.g. connected with screws 12, which are embedded in the Cu broad side plate 3 be, for example, with nuts 13 or spring-loaded wedges with the back 14 of the water tank are tense.
- this device arrangement also applies to plane-parallel mold plates of conventional slab molds as well as pre-block molds and molds for profiles, e.g. "Dogbones" or similar continuous casting formats.
- the advantages of the extension are a design simplification of the wearing part "Cu plate” and the shift of the "intelligent” (adjustable or controllable) Part of the mold with its water channels 7 on the non-wearing Chill part of the steel water tank 6 with its steel plate 9.
- the inventive solution gives the possibility that the water channels 7, due to the better material properties of the steel compared Copper can become wider, making it better and more uniform Cooling of the Cu plate 3 is ensured.
- the water channels in copper have so far been 5 mm wide and a comb thickness of 5 mm and thus lead to a water coverage of 50%.
- a higher water coverage i.e. a lower relative comb thickness 7.1
- the steel material in the steel plate 9 of the water tank be because the risk of buckling of the steel comb 7.1 once by the lower thermomechanical load and secondly due to the higher mechanical Resilience of steel becomes much lower.
- a reduction in the cooling water pressure would in turn lead to thinner Cu plate thicknesses allow, since the risk of bulging the Cu plate 3 or Cu plate surface becomes smaller due to the reduced water pressure.
- the low Cu plate thickness in turn leads to lower surface temperatures in the side 4 facing the liquid steel - hot face - the Cu plate 3, the the lifetime of the Cu plate increases.
- FIG. 2 relates to FIG. 1 with all essential features and advantages with the difference that the connecting plate 9 is not made of steel, but of a sandwich plate is constructed in such a way that on the steel plate 9.1 of the Water box 6 an intermediate plate 9.2 made of copper or a copper alloy rests, in which in turn the water guide channels 7 are incorporated.
- the intermediate plate 9.2 is between the mold plate 3 by means of the clamping screws 12. and water box 6 clamped so that no disadvantages regarding heat transfer can arise.
- FIG. 3 shows an enlarged detail A from FIG. 2 with a cooling connection 16 to the water guide channels 7 and with one in the connecting screw 12 arranged cooling channel 15, each only a schematic diagram should be, the detailed execution carried out by a specialist without further ado can be.
- the invention thus has an unexpected, multiplying, positive effect the strand quality, the mold durability and the operating costs.
