Abstract
A metallurgical product, e.g. wire rod emerging from a hot rolling mill, is subjected to controlled cooling by immersing it in a bath, e.g. an aqueous bath, kept at a given temperature. During immersion, the bath is stirred, e.g. mechanically or by means of a fluid. In a controlled cooling installation a cover arranged above the bath has a condenser for recovering vapor from the bath.
Claims4
An installation for controlled cooling of a metallurgical product, comprising, a vessel for holding a liquid bath, a device for continuously transferring the product to said vessel, a cover arranged above the vessel, said cover being provided with a condenser for recovering vapour from the bath, means for continuously raising the product from the vessel, and means for keeping a substantially homogeneous temperature throughout the bath, in which the cover of the vessel comprises:
- (a) a first portion formed by a corrugated condenser of the contact type, arranged above the vessel and extending from its inlet side to at least a point where the conveyor or the product emerges from the path;
- and
- (b) a second portion which is of a heat-insulating nature and extends from the said point at least to the outlet of the vessel.
