Definitions
- the invention relates according to the preamble of claim 1, a spray bar for a hydraulic Entzu mattersstrom with several spray nozzles arranged on its surface (see e.g. DE-A 198 05 377).
- the scale formed in the furnace, during rolling or during casting, leads to high tool or roller wear and also prevents early detection of casting defects, which reduces the quality of the final product becomes.
- Scale can be removed chemically, electrochemically or mechanically.
- An effective mechanical descaling is by means of hydraulic descaling systems possible, with the press water streams primary or secondary scale remove.
- Known hydraulic Entzu mattersanlagen have a spray bar with a plurality of spray nozzles arranged on its surface.
- a spray bar is known in which the individual Spray nozzles are switchable via separate spray valves. With such a Spray bars allow the energy and water consumption of the width of the adapt to descaling rolling stock.
- From DE 198 05 377 A1 is also a spray bar with a in a Row arranged group of spray nozzles, in which the spray nozzles can be individually switched by pressing a common adjustment.
- the Adjustment is optional in a distribution pipe for the spray water axially slidable, rotatable or in this screwed or unscrewed.
- the invention is therefore based on the object to provide a spray bar, with a high temperature stability from the beginning to the end of the To ensure good rolling and too fast cooling of the surface avoid it.
- the object is achieved in that in a spray bar the initially mentioned type of each spray nozzle is associated with a check valve.
- the unwanted residual amount of water can be particularly effectively stop by the check valves in the supply channels are arranged, preferably immediately before each spray nozzle.
- the spray nozzles in per se known Way additionally individually switchable.
- Each check valve expediently has one against the flow direction acting closing spring, so that the check valve against the Spring force of the closing spring opens.
- the spring force of the closing spring is on the in matched to the spray bar prevailing water pressure. Once the water flow is suppressed, the water pressure drops and the closing springs move the obturator of the check valve in the closed position.
- the maintenance and / or replacement of the check valves can be simplified when each check valve is switched on in a feed channel Block is arranged, which is detachably connected to the spray bar.
- FIG. 1 shows the cross section of a spray bar 1 according to the invention several arranged in a row spray nozzles 2.
- the spray bar 1 points a manifold 3, from the feed channels 4.1 to 4.8 to the spray nozzles Branch off from 2.1 to 2.8.
- the spray nozzles 2.1. to 2.8 are arranged in a row (see Fig. 2).
- a supply line 8 is connected, the manifold with a supply 9, 11 for high pressure and low pressure water combines.
- About an electro-hydraulic control 12 is either the high-pressure water with a pressure of about 200 bar or the Low-pressure water with a pressure of up to 10 bar in the supply line. 8 fed.
- each check valve 13.1 to 13.8 has one on the obturator 14 acting against the flow direction 15 closing spring 16, which causes the obturator 14 the supply channel 4.1 to 4.8 directly closes when the electro-hydraulic control 12, the water supply from the Supply 9, 11 prevents.
- the check valves 13 are arranged in blocks 17, the can be screwed into the spray bar 1.
- the blocks 17 face with the feed channels 4.1 to 4.8 corresponding inputs or outputs, so that the Flow of water through the check valves integrated in the blocks he follows.
