Manifold 30 may be of any size and shape, but is preferably square in cross section (eg, ¹ _1/4 inch on a side) and nozzles 28 are preferably spaced about 5 inches or less from one another. It is arranged by. However, this can vary to suit a particular mold and spacing arrangement. For a standard DC casting apparatus, the manifold 30 may be, for example, 1720 mm long (the long side of the ingot) and 560 mm long (the short side of the ingot). The pressure of the water supplied to the nozzle 28 should be suitable for removal from most or all of the cooling water ingot surface, preferably at least 80 psi, up to about 150 psi, more preferably in the range of 100-120 psi. , and the in each nozzle, at least 0.4 gallons per minute (gp m), giving a flow rate of up to about 1.5gp m (range ideally 0.6~1.0gp m). Mold discharge flow rate (or discharge flaw rate) (flow rate for all water discharged from the mold prior to the wiper) is preferably at least 0.6 gpm / in per linear inch of distance around the mold perimeter The maximum is 1.5 gpm / in, preferably 0.7 to 1.0 gpm / in. The high pressure hoses 31, 32, 33 and 34 are preferably easy to attach and detachable so that they can be easily disconnected and reconnected to replace one or more manifolds if clogged or other care is required. It is attached to the manifold by (quick release fittings). Furthermore, the manifolds 30 are preferably devices that can move them closer to or farther from the ingot 19 and / or move closer to the casting mold or move further away from the casting mold ( (Not shown). It is also desirable to be able to adjust the angle of the spray relative to the ingot surface so that the nozzle is rotatable about a horizontal axis and is determined depending on the situation.
