Abstract
Abstract Wire rod emerging from the hot mill is coiled and then moved through an aqueous calcium chloride bath in the form of overlapping nonconcentric loops. The wire rod is sprayed before it leaves the vicinity of the aqueous bath and then goes to a rinsing station from which it passes to a device for coiling it into a roll.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
104 words
Apparatus for cooling an indeterminate length of wire rod, comprising means to bend the wire rod into a series of coils, means to dispose the coils on a first conveyor immersed in an aqueous bath with the coils disposed on the first conveyor in overlapping nonconcentric relationship, means to remove the coils from the first conveyor and for disposing the coils on a second conveyor in a rinsing station with the coils in overlapping nonconcentric relation, means to rinse the coils with rinsing liquid on the second conveyor, and means for assembling the coils in concentric relationship in a tight roll of wire rod.
Claim 2
Dependent Claim
104 words

Apparatus as claimed in claim 1, and a hood covering said bath, said hood having a condenser in its upper portion for liquid evaporated from said bath.
Claim 4
Dependent Claim
26 words
Apparatus as claimed in claim 1, and a hood covering said bath and a hopper extending through said hood for introducing treatment material into said bath.
Claim 5
Dependent Claim
29 words
Apparatus as claimed in claim 1, and spray means for spraying water on wire rod emerging from said bath before said wire rod leaves the vicinity of said bath.
Claim 6
Dependent Claim

Apparatus as claimed in claim 1, said rinsing means comprising spray pipes above a rinsing tank through which said second conveyor passes.
Claim 7
Dependent Claim
16 words
Apparatus as claimed in claim 1, at least one of said conveyors being an endless conveyor.
Claim 8
Dependent Claim
35 words
Apparatus as claimed in claim 1, said first conveyor being an endless conveyor which is inclined from a lower end that receives the wire rod to an upper end from which the wire rod leaves.
Claim 9
Dependent Claim
27 words
Apparatus as claimed in claim 1, and guide means for guiding the coils of wire into said bath, into said rinsing station, and into said tight roll.
