Claims (2)

1 2 ken is used. These guide pieces are made up of patent claims: from two groups of grid-like guide parts that work in constant alternation and are offset next to one another 1. Cooling plate zone are arranged below a metal. Although the bars of both Continuous casting mold with several groups that are hollow from one cooling group and can be cooled from the inside Cooling units arranged in pairs, with a flow, are created on the string with cooling sub-plates, of which one or some with the oscilloscope part. One group of bars can be attached to the lating continuous casting mold are connected, since the continuous casting mold is attached and carries out its oscillation characterized in that the entire leaning movements are made, creating sliding Rei cooling plate zone (2) as a cooling grate with outward io exercise between the cast strand and the bars towards open U-shaped, generated from outside by means. It is different with the second Spray nozzles (3) with a group of bars that can be acted upon by water and which have a strand speed profile (4) is designed and that are moved along in the coolness. These bars rest select plates oblique, horizontal or vertical rend longer time on the strand surface, so that Slots (7) or grooves (5) with bores (6) 15 between the strand and the bar a certain are let in. Adjusts heat flow. Differences in heat 2. Cooling plates £ o'ne according to claim 1, characterized meabfuhr also result from the between characterized that between the cooling plate two groups of bars necessarily pair intermediate pieces (9) fixed or adjustable existing strip-shaped gaps. An even the lateral support and cooling of the 20 ßiger heat extraction in the scope of the with cooling plates Cast strand are arranged. A cooling plate zone desired cooling is thus not associated with the known solution. The present invention is to- Basically, the risk of breakthroughs through supports 95 to further reduce the strand surface by means of cooling plates, so that also in the gap between the The invention relates to a first pair of cooling plates swinging under the cooling plate zone and the following a metal continuous casting mold with several, lowing, stationary cooling plate pairs even with increased Pouring speed in pairs, flowed by a coolant, no reduction in the number of cooling plates, one or some of which have an effect. In other words connected to the oscillating continuous casting mold, the cooling effect of the cooling plates is to be increased, are. The task at hand is given at the beginning The cooling plate zone is solved in place of the individual cooling plate zones mentioned in that the ge support rollers smaller diameter than the rest of the entire cooling plate zone as a cooling grate with the outside to the support roll frame of the continuous caster belonging to 35 open U-shaped, from outside by means of renden support rollers applied. This includes spray nozzles with profiles that can be acted upon by water assumed that the inside liquid pouring is formed and that inclined in the cooling plates, strand, whose outer solidified shell still has slightly horizontal or vertical slots or grooves is deformable, by means of flat, cooled plates Si holes are embedded. This is for the can be supported more reliably than by the support rollers, between cooling plates despite their extremely simple shape see which the strand can bulge. Cooling - relatively large surface area for heat dissipation also serve to conduction the targets. Because the cooling plates are freely accessible from the outside To cool the strand while it is in use, the supply of splash water can be unhindered from support rollers with splash water between the rollers on the panel surface. Fergekühlt is advantageous will. 45 ner that scale getting under the cooling plates It is known (Swiss patent leaks into the slots and there by Beaufschla-456 859), the first cooling zone following the mold can be rinsed out with cooling water. from tenpaar to connect with the mold, so that this particular advantage is, however, the more intensive Kühlmit the mold oscillates. The effect of the oscillation on the cooling plates themselves, so that these imbedingte increased distance between successive stands, more heat than before from the strand hanging up As a result, cooling plates will become rigid in one zone, making the strand shell faster kerer strand shell laid what the breakthrough grew and experience in the gap between the vibrating should reduce considerably. The most known pair of cooling plates and the following dormant Cooling plate zones also have cooling plates with cooling plate pairs consequently a greater thickness than the more complex ones Cooling water supplies that the 55 ago is available. At risk of constipation. According to the further invention, it is advantageous that The cooling plate itself is then only fixed in intermediate pieces between the pairs of cooling plates smallest possible. The diminished war or adjustable for lateral support and deep withdrawal due to insufficient cooling of the cast strand with cooling water, »The supplied cooling plate raises the problem again.
