A uniform for the lateral support and cooling of the external heat extraction in the scope of the cast strand with cooling plates. A cooling plate zone aimed at cooling is therefore not associated with the known solution. The present invention is to- Basically, the risk of breakthroughs through supports 35 of the strand surface by means of cooling plates decrease 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 a cooling medium flowing through it, pouring speed in pairs, no reduction in the cooling order Cooling plates, one or some of which are effective. 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 tend 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 40 cooling plates despite their extremely simple shape see which the strand can bulge. Cooling - relatively large surface area for heat dissipation also serve to through 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 spray water can be unhindered from support rollers with splash water between the rollers on the panel surface.

The effect of the oscillation on the cooling plates themselves, so that these inifcedingte 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 empty 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.
