Spray-type Crystallizer is to change the tube mold isolation water seam to spray water cooling, that is, spray from the nozzle spray water directly to the mold copper tube to achieve cooling. The cooling efficiency is high and the water saving effect is obvious. The spray type Crystallizer has the advantages of simple structure, low sealing requirement, and avoids the problem of not adjusting the angle cooling intensity of the copper tube, the cooling strength is relatively weak and the temperature distribution is uneven. The spray mould has been widely used in billet continuous casting machine. Theoretically, the spray-type Crystallizer can use the general cooling water, but in the actual production of scaling, nozzle clogging problems caused by the accident affected the use of spray-type Crystallizer.
