Definitions
- the invention relates to a cooled continuous casting mold for casting metal, in particular steel, in slab format and here in particular with a thickness between 40 to 400 mm and a width of 200 to 3,500 mm, with mold walls made of plates and with cooling medium channels for cooling.
- the mold cooling water 9 flows at a controlled speed (10), expressed for example in m / s, a predetermined pressure (11), which is measured in bar at the mold cooling water inlet, and a controlled cooling water inlet temperature, T-0 (12), which on Mold cooling water inlet is measured, parallel to the mold height 13 in or against the continuous casting direction 14, measured in m / min, in order to absorb and dissipate the heat flow J (2) offered.
- the total heat flow J (2) removed from the mold cooling water 9 is determined by the total resistance R - total (15), which is determined by the individual media 16 with their individual resistances Ri (17), namely between the middle 4 of the strand and the mold cooling water 9.
- the individual resistances 17 are determined are characterized by their length I (18), their specific thermal conductivity ⁇ (19) and their line cross-section F (20) and make up the mass flow equation (20.1) with the potential gradient U (3) and the heat flow J (2).
- the resistances of the individual media between the mold center 4 and the course of the Chill water such as the resistance of the molten steel, the strand shell, the slag, the refractory lining and the mold plate, which consists in particular of copper.
- the heat flow arriving at the phase boundary 21 between the copper plate 7 and the course of the cold water 9 must overcome the interface resistance 22 between the copper of the mold plate and the cooling water, which means that between the phase boundaries 21 and 21.1, which the Phase boundary between the copper plate 7 and the slag film 6 or the strand shell 5 or "hot face", the copper plate 7 each sets a skin temperature or a temperature gradient 25.
- This temperature gradient depends on the strength of the heat flow over the mold height 13 and on the interface resistance 22 at the copper / water phase boundary (21). It is also known that the heat flow from the mold level 30 to the mold outlet 13.2 is reduced according to a profile 2.1 - known as a "heat lobe".
- the interface resistance 22 is determined by the size of the cooling channels 26, which run parallel over the mold height 13, here in the form of cooling slots, which have a width (26.1), depth (26.2) and thus a flow cross section Q (26.3) and a length (26.4) in about the height of the mold (13), apart from the boundary layer (Nernst layer) of the cooling water, which is a function of the flow velocity 10 (see FIG. 3e).
- the resistance 17 is determined by the percentage water coverage (27.2) over the mold width, defined as the difference between the maximum cooled mold width minus the not directly cooled mold width, divided by the cooled mold width or, in a first approximation, defined by the distance between cooling channel and cooling channel 27 minus the web width 27.1, divided by the distance between cooling channel and cooling channel (see Fig. 3e).
- the resistance 17 depends on the copper plate thickness I (8) and on the specific thermal conductivity ⁇ (19) and the water velocity (10), which is a function of the water pressure (26.6) at the mold water inlet and the flow resistance (26.5) or the pressure loss in the mold.
- this interface resistance 22 is constant over the mold height 13.
- the shape of the cooling channels can be realized either by cooling bores 28 (not shown) with a constant diameter with and without displacers 28.1 or cooling slots 26 with water baffles 26.7 (FIGS. 3d and 3e) and constant cross section Q (26.3).
- T-Cu-Re mold plate recrystallization temperature
- the mold skin temperature on the side facing the steel (23) is between 300 ° C. and 400 ° C., depending on the casting speed, and is less close to the recrystallization temperature (31) of the cold-rolled copper than the standard slab.
- the recrystallization temperature of the cold-rolled copper plate is between 350 ° C (Cu-Ag) and 700 ° (Cu-CrZr) or 500 ° C (softening temperature).
- a further reduction in the copper plate thickness (18.1) is due to the high water pressure (at the mold water inlet) (26.6) in the bores (28) or cooling slots (26) and thus because of the possible mechanical bulging of the copper plate surface facing the steel, “hot face "(21.1), as difficult.
- Figure 3 shows a known arrangement of the water cooling for a slab or thin slab mold with cooling slots 26 and water baffles 26.7.
- Fig. 3a shows half the broad side 7 of a slab mold with the narrow page 7.1 and a dip spout 35 and the steel flow 36 and the strand 37 with the strand shell 5 on the mold spout.
- This figure shows the uniformly parallel cooling slots 26 over the mold height 13 and the position of the casting level 30.
- FIG. 3b shows the section through the mold broadside 7 with a water box 38 both for the water flow 38.1 and for the water return or water box inlet 38.2.
- the transition for the mold cooling water from the water tank (38.1) into the cooling slots (26) or cooling bores (28 - not shown) is designated by 38.1.1 or 38.2.1.
- a multi-part mold with clamping bolts 39 is clear, either for the connection of the copper plate with cooling slots 40 to the water box 38 or the connection of the copper plate without cooling slots 40.1 to the water box 38, but then with an intermediate plate 41, which with cooling - slots 26.3 is provided (cf. Fig. 3d).
- the intermediate plate 41 can also directly form the wall of the water box 41.1 (FIG. 4).
- FIG. 3c the profiles of the mold skin temperature (“hot face”) 23, the heat flow J (2) and the recrystallization temperature, T-Cu-Re (31), over the mold height (13) are shown as prior art.
- Fig. 3d shows a horizontal section through the mold and leaves the
- the parallel cooling slots 26 are shown in horizontal section.
- the figure shows the slot width 26.1, the percentage water coverage 27.2, which results from the ratio of the cooling channel width to the distance between cooling channel / cooling channel 27, the cooling channel cross section 26.3, the water guide plates 26.7, the distance between cooling channel / cooling channel 27 and the copper plate thickness 8.
- Figure 4 shows possible known constructions of a mold broad side 7, consisting of the copper plate and the water box 38.
- the mold can be made of a copper plate with cooling slots 40 and water box 38 (part 4a) or a copper plate without cooling slots 40.1 and an intermediate plate 41 with cooling slots (Sandwich) and water box 38 (part 4b) or from a copper plate without cooling slots 40.1, which is mounted on the intermediate plate 41.1, which also forms the wall of the water box (part 4c).
- Sub-figure 4d again shows the profiles of the heat flow J (2.1) and the thermal load over the mold height as well as the recrystallization temperature (31) of the cold-rolled copper plate (31).
- the object of the invention is to provide a continuous casting mold in which the thermal load over the mold height, ie the thermal profile over the mold height, is evened out and thus the mold skin temperature in the mold level can be reduced.
- This object is achieved with a continuous casting mold with the features of claim 1.
- Advantageous embodiments are disclosed in the subclaims.
- Width is the measure of the extent of the channel wall, which runs (essentially) along the hot plate inner wall.
- the cross-sectional area of the cooling channels is preferably rectangular. Elliptical shapes are also conceivable.
- the phase interface between the mold plate wall and the mold water from the mold inlet to the mold outlet is reduced.
- the width of the cooling medium channels is reduced in a first approximation to the heat flow profile via the mold height between the mold inlet and the mold outlet in the casting direction, the breeding boundary lines or surfaces of a cooling medium channel or adjacent cooling medium channels not running parallel.
- the width of the cooling medium channels narrows linearly in the first approximation in the casting direction, the border lines or surfaces of a cooling medium channel or adjacent cooling medium channels not running parallel but at an acute angle to one another.
- Cross-section of rectangular channels diverge at a defined angle or the lines of adjacent channels of elliptical cross-section, seen in a sectional plane that intersects the common centers of the channels parallel to the cooling plate surface, form a defined angle to one another.
- the cooling channels are designed so that the depth of the cooling channels increases over the mold height from the mold inlet to the mold outlet in the casting direction.
- Depth means the dimension of the cooling channels that is required in connection with the width to calculate the area.
- the increase in the depth dimension over the mold height changes accordingly such that the amount of the respective cross-sectional area of a cooling channel remains constant from the mold inlet to the mold outlet and thus the flow rate of the cooling medium in the cooling water channels between the mold entrance and the mold exit is constant.
- Water boxes are preferably used to supply the cooling channels introduced into the mold wall plates.
- the water box outlet is arranged at the level of the mold inlet and the water box inlet at the level of the mold outlet.
- the water supply is arranged above the pouring level at the mold inlet and the water return at the mold exit, so that cold, thermally unloaded water with the water in the pouring level area under which the highest thermal load develops greatest cooling capacity or the greatest distance from the evaporation point of water at pressures between 1 and 25 bar.
- the cooling channels can be cooling slots or bores.
- the cooling slots are introduced from the side of the plates facing away from the inside of the mold or into separate intermediate plates.
- the cooling slots are closed over the mold height with appropriately shaped water baffles, the width of which is adapted to the change in width of the cooling channel profile over the mold height from the cooling water inlet to the cooling water outlet. decreases, and its thickness preferably decreases correspondingly over the mold height from the cooling water inlet to the cooling water outlet when flush with the opposite side of the plate.

- the prior art has already been described in detail.
- the invention will now be described by way of example in comparison with the prior art with reference to FIGS. 5 and 6.
- the same components as the molds shown in FIGS. 1-4 are provided with corresponding reference numerals.
- the partial figure 5a characterizes the invention, in which adjacent cooling slots 29 or their boundary lines do not run in parallel, but rather decrease in width from the cot entrance 13.1 or from the mold level 30 to the mold exit 13.2 and thus the channel cross section or the interface F (20) is functionally related to the heat flow density or to the heat flow profile 2.1.
- the flow cross section Q (26.3) for the cooling water and thus the flow velocity 26.5 of the water can be kept constant in the first approximation.
- the boundary surfaces of the cooling channels in the form of cooling slots 29 no longer run parallel, but form an acute angle 29.2 to each other.
- the percentage water coverage 27.2 or the line cross section 20 is thus, for example, in the casting level 30 at max. 100% in the case of casting a thin slab and at the mold outlet at a minimum of 30%.
- FIG. 5 c shows the thermal load 23.2 of the mold plate that is evened out over the mold height 13 in comparison to the heat flow profile 2.1 and the recrystallization temperature 31.
- the figure shows that the "hot face" temperature 23.2 of the copper plate 7 is lower, runs more regularly and at the same time the service life of the copper plate is extended.
- the partial figure 5d shows the cuts A-A'-A "and B-B'-B" through the broad sides 7 of the mold inlet 13.1 and mold outlet 13.2 both for the mold plate (40) with non-parallel cooling slots and for the sandwich solution, ie a mold plate with an intermediate plate 41, into which the non-parallel cooling slots 29 are introduced according to the invention.
- the partial figure 5e shows the cooling channels 29 at the mold inlet 13.1 and mold outlet 13.2 with their guide plates 29.1, which vary in width and depth.
- FIG. 6 represents the inventive solution (sub-figure 6b) according to the prior art
- the drilling cross sections over the mold length can be changed by using conical displacement rods (not shown).
- intermediate mold center (4) and mold water (9) such as liquid steel, refractory material, strand shell, slag, mold plate made of copper, for example
- Cooling channel width 26.1 Cooling channel width 26.2 Cooling channel depth
- Percentage water coverage over the mold width defined as the difference between the maximum chilled mold width minus the not directly chilled mold width divided by the cooled mold width or, in a first approximation, the distance between cooling duct / cooling duct minus the web width divided by the distance between cooling duct / cooling duct, corresponds to the line cross-section, F (20) in the sense of the mass flow equation (20) 28 cooling holes
