Apparatus for the controlled cooling of wire rod from its rolling temperature

Claim 2

Apparatus for the controlled cooling of wire rod from its rolling temperature, comprising: (a) an elongate base; (b) a first cooling assembly mounted on the base and composed of a plurality of modules each having a length equal to a predetermined modular length multiplied by an integar, said first cooling assembly being adapted to guide the wire rod rectilinearly and to cool it with water; (c) a turn-laying unit mounted on the base following the first cooling assembly for forming the wire rod into turns and laying these turns in a staggered disposition; (d) and a second cooling assembly mounted on the base following the turn-laying unit for receiving the staggered turns and conveying these continuously and composed of a plurality of modules each having a length equal to the said modular length multiplied by an integer; (e) the turn-laying unit being disposable on the base selectively at a plurality of different positions along the base, whereby the lengths of the cooling assemblies can be changed by selection of the disposition of the turn-laying unit and of the modules composing said assemblies.

Claim 3

Apparatus for the controlled cooling of wire rod from its rolling temperature, consisting of a first part which guides the wire rectilinearly and cools it with waterin portions, a turn-laying unit which forms the wire into turns and lays the turns in staggered disposition, and a second part comprising a continuously running conveyor which receives said turns and allows passage for an approximately vertically directed stream of cooling medium and its access to all turn portions, and which conveys the wire turns to a coil forming station disposed after the conveyor and which collects them and forms them into coils, the turn-laying unit being adjustable along the apparatus for changing the actual lengths of the first and second parts, characterised in that the said two parts are composed of a plurality of modules of the same basic modular length or an integral multiple of the basic modular length, and the apparatus has a base frame which carries the modules and on which the turn-laying unit is also fixed so that it is displaceable in the longitudinal direction, the modules or groups of modules differing in their guide or conveying function and/or influencing the cooling action in different ways.

Claim 4

Apparatus for the controlled cooling of wire rod from its rolling temperature, consisting of a first part which guides the wire rectilinearly and cools it with waterin portions, a turn-laying unit which forms the wire into turns and lays the turns in staggered disposition, and a second part comprising a continuously running conveyor which receives said turns and allows passage for an approximately vertically directed stream of cooling medium and its access to all turn portions, and which conveys the wire turns to a coil forming station disposed after the conveyor and which collects them and forms them into coils, the turn-laying unit being adjustable along the apparatus for changing the actual lengths of the first and second parts, characterised in that the said two parts are composed of a plurality of modules of the same basic modular length or an integral multiple of the basic modular length, and the apparatus has a base frame which carries the modules and on which the turn-laying unit is also fixed so that it is displaceable in the longitudinal direction, the modules or groups of modules differing in their guide or conveying function and/or influencing the cooling action in different ways.

Claim 5

Apparatus as claimed in claim 2 in which the modules of the first part are provided with pipe pieces which guide the wire rectilinearly.

Claim 6

Apparatus as claimed in claim 3 in which in at least one module of the first part the pipe pieces are provided with a cooling water feed, and a collection tank is provided for the discharged cooling water.

Claim 7

Apparatus as claimed in claim 2 in which the modules of the second part are in the form of basic units of a conveyor for conveying the staggered wire turns layers thereon and of which the conveyor provides passage for an approximately vertically directed stream of cooling air and access therefor to all wire turn portions.

Claim 8

Apparatus as claimed in claim 5 in which a frame in which are provided vertically operating fan impellers is disposed below at least one conveyor module.

Claim 9

Apparatus as claimed in claim 5 in which an air chamber fed by a blower is disposed below a plurality of the conveyor modules.

Claim 10

Apparatus as claimed in claim 5 in which the conveyor is composed of sections driven at different speeds and modules which are disposed in or belong to one section of the conveyor are disposed higher than modules of a subsequent section driven at a different conveying speed.

Claim 11

Apparatus as claimed in claim 8 in which the higher disposed modules are supported on the base frame by shims of corresponding thickness.

Claim 12

Apparatus as claimed in any one of claims 5 to 9 in which a plate of a constructional material which restricts the heat radiation, and which is provided with slots for the passage of a stream of cooling air, is disposed below at least one module of the said second part.

Claim 13

Apparatus as claimed in any one of claims 5 to 9, in which at least one module of the second part is provided with means restricting heat radiation.

Claim 14

Apparatus as claimed in any one of claims 5 to 9 in which at least one module of the second part is provided with heat radiation-restricting means comprising plates of material which restricts heat radiation, and U-shaped hoods of material which restricts heat radiation in order to form portions of a heat-retaining tunnel.
