Abstract

A drain apparatus that is capable of draining a large volume of liquid cooling medium flowing downward along a strip steel. The drain apparatus is one comprising paired upper nozzles (35) and lower nozzles (36) disposed opposite to each other so as to have strip steel (S) interposed therebetween on the exit side of primary cooling zone (1) and secondary cooling zone (2) for cooling vertically conveyed heated strip steel (S) with the use of steam water (C), wherein on the planes of the upper nozzles (35) and lower nozzles (36) opposite to the strip steel (S), superior slits (35b,36b) and inferior slits (35c,36c) for drain of cooling water (W) flowing downward along the strip steel (S) by jetting of air (A), furnished with openings approximately perpendicular to the direction of conveyance of the strip steel (S) are provided along the direction of conveyance of the strip steel (S).
