Definitions
- the invention relates to a plate mold for producing strands of steel, in particular thin slabs, with water-cooled narrow side walls that can be clamped between wide side walls and with devices for adjusting the cavity formed by the narrow and wide side walls into different strand dimensions and the casting cone and with an oscillation device.
- Mold walls have cooling chambers that include certain cooling areas.
- Measuring elements for determining the amount of heat dissipated or the cooling capacities are connected to the water supply and drain lines on the broad sides. Furthermore, an average value of the cooling capacity of the cooling chambers is simultaneously formed in the measuring elements, which is fed to an average former with which the conicity of the narrow sides can be controlled.
- the broad side walls are divided into at least three mutually independent cooling segments in the casting direction. These cooling segments are arranged in such a way that the respective outer ones have the same structure and enclose between them a middle segment which can be divided into several zones.
- actuators are used to control:
- Outlet water temperature and the amount of water measured, the amounts of water can also be controlled independently.
- the arrangement according to the invention in at least three zones and the comparison of the specific heat flows in these zones with respect to one another makes it possible to recognize an asymmetry, particularly in relation to that in the immersion pouring area. A non-uniform heat transfer due to turbulence of the steel in the mold can also be seen.
- a possible deviation in the center of the mold goes hand in hand with longitudinal cracks in the surface of the strand to breakthroughs (adhesive). These longitudinal cracks occur particularly in the middle slab area next to the center axis in the area of the immersion spout, that is to say in the area of the relatively thinner slag lubrication film.
- This thinner slag lubrication film leads to an increased heat flow and thus to a non-uniform partial strand shell formation with regard to the increased Thickness, the reduced temperature and the increased shrinkage.
- This non-uniform partial strand shell formation leads to longitudinal cracks and, in extreme cases, to the sticking of the strand in the middle of the broadside of the mold and to breakthrough.
- the device reveals a migration of the strand in the direction of one of the narrow sides with a corresponding risk of breakthrough due to hangers, which can then be counteracted by conicity control.
- the invention therefore not only allows the casting parameters to be changed during the casting, in particular for securing breakthroughs, but also the development of the mold shape in conjunction with the immersion pouring mold, both inside and outside, and of the casting powder to form an optimal “mold” system.
- FIG. 1 shows schematically the structure of a plate mold in cross section and FIG. 2 in longitudinal section.
- a top view of the mold is shown in the upper part of the picture.
- a straight-walled mold is shown for the continuous casting of slabs.
- the broad sides have a first side segment 11 and a center segment 13, each of which has chambers, or a first segment 21 and a center segment 23, which have vertically arranged bores for guiding the cooling water.
- a narrow side 31 adjustable via an adjusting device 33 is clamped between the broad sides.
- a so-called dent mold is shown in the right part of the picture. It has a width segment 12 and also a center segment 13, each of which has cooling chambers, or a side segment 22 and a center segment 23, which has cooling bores.
- the center segments 13 and 23 are further divided into zones 14 and 15 or 24 and 25.
- a narrow side 32 is clamped between the broad sides 12 and 22 and is adjustable for an adjusting device 33 by means of an actuator 63.
- the broad sides 11 to 15 and 21 to 25 and the narrow sides 31 and 32 have feeders 51, 53, 55, 57 and discharges 52, 54, 56 and 58 through which a
- Coolant can be supplied and removed.
- An immersion pouring tube 41 or 42 is introduced into the mold interior of the mold.
- thermal sensors 61 and 64 are arranged, which are connected to a controller 62, which acts on the actuator 63 or an oscillation device, not shown .
- the side view of the mold is shown with the identical positions already mentioned.
- the lower adjusting device 34 or 36 of the narrow sides 31 or 32 is shown.
- the die mouth is designated 29 Position list
- Coolant system 51 Inlet side segment 1 52 Drain side segment 1 53 Center segment feed
