Definitions
- the invention relates to a device for the continuous casting of metal, in particular of steel, with a plate mold or a tubular mold with mold walls and with a mold cooling device.
- a device for the continuous casting of metal in particular of steel
- a plate mold or a tubular mold with mold walls and with a mold cooling device is used for casting different Strand formats, such as slabs, thin slabs, blooms or beam blanks.
- the mold itself or the As in horizontal continuous casting the strand oscillates. But the mold itself is arranged in one place and can therefore also be referred to as a stand mold become.
- Such molds as a casting mold for continuous casting plants either consist of Mold plates, namely two plates for the mold wide plates and two plates for the mold corn sides, or from mold tubes.
- mold plates or mold tubes are made of copper and have in the Usually a thickness of 10 to 50 mm between the water cooling and the Melting steel side facing.
- the choice of copper plate thickness depends on the heat loads or the heat flow, measured for example in MWh / m 2 or MW / m 2 .
- the thickness of the copper plates of the mold is between 25 and 50 mm.
- thin slabs which are operated at casting speeds of up to 10 and in the future up to 15 m / min, have a maximum heat flow of 4-5 MW / m 2 and copper plate thicknesses of 10 to 25 mm.
- the copper wall would have to become ever thinner as the Water cooling. This is difficult, since thinner walls are always used worse the high water pressures of 5-15 bar, for a corresponding Ensure water speed of 5-15m / s, steadfast without deformation.
- copper plates formed too thin at too high a thermal load on the cold-rolled copper Loss of strength if the recrystallization temperature is exceeded.
- assembly of very thin cocitia copper plates on the mold frame The mold plates are usually opened the water boxes or the mold frame are mounted by means of bolts, which by means of of a thread can be screwed into the back of the copper plate. This is not possible with very thin plates; here the bolts must be on the Copper plates are welded on.
- the invention has for its object a device of the generic type Art in such a way that the above disadvantages despite increasing the Pouring speeds no longer occur.
- a device can be created for continuous casting with a mold, the high heat flows can be transported away and can withstand high thermal loads. Also the Assembly can be improved.
- At least one mold wall be a Steel mold wall and a support grid for this steel mold wall includes that a magnetic field generator is available for generating a magnetic field that acts on the steel mold wall via the support grid and thus the steel mold wall pulls on the support grid, and that the Kokilienkühin worn a spray cooling includes.
- a mold which is a thin mold wall with high and controlled heat dissipation properties even at high Has casting speeds.
- the mold wall is exposed on the one hand a steel mold wall pointing towards the molten metal and on the other hand composed of a support grid to stabilize this steel mold wall. Due to the magnetic attraction, the steel mold wall can be simple to be assembled.
- Such a mold also has the particular advantage that the steel mold wall exposed to wear from the molten steel unlike a more expensive copper plate, fast and if necessary can be easily replaced by the high quality machining Used is "thrown away", i.e. fed back into the steel recycling process becomes.
- With the help of the proposed double wall consisting of thin steel wall and support grid can be a simple and less expensive Kokitlen spray cooling are used.
- the spray cooling acts in the open chambers left by the support grid or passages, i.e. the thin steel mold wall is cooled immediately, but still experiences a relatively high support effect.
- spray cooling the use of splash water is possible.
- the invention Solution creates a mold that has thermal conduction would otherwise require a copper plate thickness of about 10 mm or more, which is easy to mount on a base frame and which is a mold cooling allows water side and at the same time is inexpensive.
- the steel mold wall proposed according to the invention preferably has a thickness between 0.5 and 5 mm, its effect corresponds to one Copper plate with a thickness of 10 mm, but has constructive advantages and price advantages on.
- the support grid preferably has a support wall with a wall inserted therein. chambers on, i.e. the individual chambers or breakthroughs of the grid are from surround the wall webs of the support wall, the magnetic field via the support walls is introduced into the mold wall.
- the spray cooling for cooling the mold walls preferably comprises spray nozzles, the steel mold wall in the back of the support grid, i.e. cool through the freely accessible chamber areas or gaps in the grid.
- These spray nozzles of the mold spray cooling as well as the feeds for the Cooling medium, especially water, are in the support walls of the support grid fully or partially integrated. Overall, the support grid or the support walls formed thick in relation to the steel mold wall.
- the proposed spray cooling has the advantage that the intensity of the spray cooling Functional to the energy flow in the mold wall over the mold height is adjustable. This energy curve shows approximately in the upper third of the mold a heat maximum.
- a further development of the device suggests that a device for control the surface temperature of the side of the liquid metal facing the Steel mold wall is in place to spray cooling if necessary to adapt a control mechanism to fluctuations in the surface temperature.
- the mold plate can also be mechanically fixed to the support grid.
- a fixing device is proposed for fixing the steel mold wall for example a broadside in the middle of the broadside above the Mold height.
- the steel mold wall at the mold entrance or at The mold exit can be fixed horizontally.
- the narrow sides if they are also stabilized with a support grid, be fixed.
- the support walls of the Support grids at their ends facing the steel mold wall are equipped with balls that act as (ball) bearings for one serve free, thermally induced, movement of the steel mold wall.
