This has the advantage that the flange edges of the Beam blank profiles by draining the water no undefined cooling Experienced.
- the drain water After lifting the drainage water over the lateral edges of the beam Blank profile, the drain water flows controlled into the discharge device. That so discharged water flows into the underlying sintering trough. Their job is in collecting the drainage water, the scale and the foundry powder residues from the cooling process in the casting arc.
- the sintering trough is seen in the longitudinal section of such a system below the G confusebogens arranged and formed in such a width that they from the G confusebogen falling water, which with scale and G manpulver Wegwalln enriched as much as possible.
- the collected and with Solids contaminated cooling water is processed in the water management of the system and then returned again as cooling water of the Beam Blank casting machine.
- a device for draining drainage water from the inner arc of the strand guide a beam blank casting machine for carrying out the method comprises a discharge device at the bottom of the inner arc of the strand guide between lateral edges of the beam blank profile, wherein the discharge device guided in height adjustable in guide rails and to a supply pipe for a Pressure medium is connected to generate the nozzle jets, and jet nozzles for emitting the drainage water in the inner arc of the beam blank profile oppositely directed high-energy nozzle jets are arranged.
- a sintering trough is located in a region below the discharge device for catching from the inner arch of the beam blank profile overflowing Downstream arranged, which provided with at least one drainage member this is advantageous with a cleaning and water recycling system the water industry is connected.
- a Beam Blank casting machine can be used with any type of casting machine Be provided number of casting strands. Will a Beam Blank Caster for designed several casting formats, so the discharge device with a replaceable head equipped. Depending on the format to be cast, the dimensions will be one the beam blank tuned nozzle assembly / Ableitan Aunt provided in any case, this to the beam blank in a defined position must be brought. As a result, the discharge device can also by means of Roll positioned offset from the inner bow. Here, the process engineering optimal position are used.
- Figure 1 is a side view of a beam blank casting machine to see, with a Mold 2, a strand guide 3, with guide rollers and with spray nozzles 5, the cooling water between the rollers of the strand guide 3 for cooling the cast Beam blanks, e.g. a Vorprofil for the Suspray supply.
- the The Spotify cooling water collects in the inner arc of the strand guide 3 and runs in the inner bow 4 of the Beam Blank profile on the bridge between the lateral profile edges 11 in strand withdrawal direction.
- the drainage water adds in strand withdrawal direction from nozzle row to nozzle row and hinders the one hand, the heat transfer by spray cooling and leads on the other hand, to a water accumulation, the controlled cooling of the Beam blanks obstructed.
- the drain water by means of a discharge device. 6 from the surface of the beam blanks in the area of the Beam Blank inner arc 4 derived.
- the drain water 7 of the discharge is in a below the strand guide arranged sintering 9 collected and is from the Sinterrinnne 9 by means of a Wegorgangs 20 for treatment in the water industry directed the investments and of this u.a. to the water cooler the beam blank casting machine returned, which is not shown in detail is.
