The present invention relates to a spray structure for a rolling mill comprising a filter unit (100). The filter unit comprises a filter unit body (110); an inlet (120) in which fluid flows; an outlet through which the fluid flows out (121); a filter (130) which is provided inside the filter unit body (110) to remove foreign substances when the fluid flowing in the inlet (120) passes through the filter; a space (140) which is formed between the inlet (120) and the filter (130); a foreign substance discharge unit (114) which is provided on the bottom surface thereof to discharged foreign substances loaded inside the space (140); and a discharge means (150) which is configured to discharged the foreign substances through the foreign substance discharge unit (114). The low pressure water, which is supplied to a low pressure by the filter unit (100), is removed with the foreign substances to prevent the malfunction of a check valve provided on a spray nozzle (10) to prevent the outflow of the low pressure water at a rear plate (12); and consequently, prevents the freezing of the rear plate (12) or the malfunction of a sensor measuring the thickness of the rear plate (12). |
