Abstract

PURPOSE: To cool the high temperature steel sheet from downside with good responsiveness, by forming the punched hole in the cooling water baffle plate or baffle cylinder, and by reciprocating this baffle plate or by rotating the baffle cylinder in order to permit the cooling water to spout from the nozzle or to cease the spouting.
CONSTITUTION: The baffle plate 11 to be reciprocated by the cylinder 13 through the guide 12 is installed in the lower header 5. In this baffle plate 11 the punched hole is arranged so as to oppose to the lower nozzle 6. When the cooling water is to be spouted from the nozzle 6, the baffle plate 11 is moved to locate the punched hole of the baffle plate 11 just above the nozzle 6. When the spout of the cooling water is to be stopped, the baffle plate 11 is moved to locate the punched hole at the position lacking the nozzle 6. As a result, the high temperature steel sheet (strip) can be cooled from downside with good responsiveness.
