The position sensor 3 is electrically connected with the delay switch 4, the delay switch 4 is electrically connected with the electromagnetic valve 5, the delay switch 4 controls the opening and closing of the electromagnetic valve 5, the electromagnetic valve 5 is arranged on a pipeline of a spraying water system, a spraying water system nozzle 6 is arranged at the tail end of the pipeline, the horizontal spraying angle of the spraying water system nozzle 6 can be adjusted, and the delay switch 4, the electromagnetic valve 5 and the spraying water system nozzle 6 are all arranged on one side of the conveying roller way 2. The position sensor 3, the delay switch 4, the electromagnetic valve 5 and the spray water system nozzle 6 are all located at the position before the high-temperature plate blank 1 reaches the number spraying machine, and the spray water system nozzle 6 is located between the position sensor 3 and the number spraying machine.

After a continuous casting blank is cut into a fixed size blank, the blank is transported by means of a conveying roller way, a position sensor 3 arranged on one side of the conveying roller way 2 senses a casting blank signal at a certain distance before a high-temperature plate blank 1 reaches a spray marking machine and transmits the signal to a descaling cooling system and a delay switch 4, the descaling cooling system starts to adjust the horizontal spray angle of a nozzle after receiving the signal, the horizontal spray angle adopts the prior art, when the high-temperature plate blank 1 runs to a trigger position of the delay switch 4, a spray water electromagnetic valve 5 is opened, high-pressure descaling water is sprayed out from a spray water system nozzle 6 and is just sprayed to a set starting position on the high-temperature plate blank 1, meanwhile, the conveying roller way 2 is utilized to drive the high-temperature plate blank 1 to run at a constant speed, and the aim of automatically descaling and cooling the cut section of the casting blank is fulfilled by delay control (type selection according to the section size, after the descaling and cooling of the cut section 7 of one plate blank are finished, the pressure water is closed through the spray water electromagnetic valve, and a descaling and cooling cycle is also finished. When the next casting blank passes through the channel, the signal is turned on again to perform the circulating work, so that the full-automatic descaling and cooling of the casting blank are completely realized. The descaling method is to spray high-pressure water to the cut section of a high-temperature casting blank, so that the oxidized slag on the section is rapidly cooled and contracted, and then is embrittled, cracked and peeled. The method can be used for descaling and cooling all high-temperature slab continuous casting cutting sections and can also be used for descaling and cooling the side surfaces of casting blanks.
