(54) DEVICE FOR COOLING WIRES

The invention relates to heat treatment of wire.

A device for cooling the wire is known, comprising a drum with transport augers and nozzles. For supplying a coolant ij.

A device for cooling wires is known, comprising a horizontally arranged cylindrical body with nozzles for supplying a cooler 2.

A disadvantage of the known devices is the impossibility of obtaining a water jacket on the inner wall of the Kopnycai, which is necessary to intensify the cooling.

The aim of the invention is to provide intensive cooling of the wire.

The goal is achieved by the fact that the device is equipped with a rotational drive connected with a drum, the inner surface of which has spiral guides, while at the entrance to the body there are nozzles for water supply at an angle of 10-20 ° and opposite of air.

FIG. 1 shows a cooling device, end view on

fig 2 is a section AA in FIG. 1 in FIG. 3 is a section b-B in FIG. 1} in FIG. 4 shows a section B-B in FIG. 2} with FIG. 5 - it is possible to insert a transporting screw on the inner wall of the cooling drum.

A device for intensive cooling, standing vertically turns

4Q wire consists of a cooling drum 1 installed on four ax roller 2, a drive 3 and special moving turns of the wheels 4. A guide is provided on the input side of the cooling drum

15 an inclined surface 5. A cooling drum 1 along the inner wall is provided with a helical profile 6. From the entrance side at the periphery of the cooling drum 1 for supplying

20, water-splashing nozzles 7 are placed in the inner wall of the drum with cooling water. On the exit side of the cooling drum, nozzles 8 for compressed

25 air, which stabilize and regulate the water jacket 9 formed in the cooling drum. To collect and cool the sprayed water from the inlet and outlet side

30, annular catchments jHHKM 10 and 11 are provided. Instead of the wind-shaped Profile 6 on the inner wall of the cooling drum 1, transport augers 12 along the axis can also be used.

The operation takes place in the following manner.

Standing turns of wire 13 direct horizontal or slightly inclined cooling drum 1 open on both end sides. The 3 O drive of the cooling drum serves to simultaneously drive the wheels 4 moving the turns. These wheels transport standing turns of wire through an inclined surface 5 to 15 of the cooling drum. The inner wall of the cooling drum at the entrance has a spiral profile (Fig. 2) or transporting augers 12 (Fig. 4), due to which 20 bursts of wire turns are moved and partially the water jacket 9 is moved. To cool the wires around the periphery to the inner a cooling water wall is tangentially injected from the cooling drum wall from the entrance side at an angle about IS to the direction of movement of the cooling drum periphery so that a component of the cooling water motion Q in the direction of transportation. The rate of flow of cooling water from the spray. the water of the nozzles 7 is so determined by the pressure of the water that the component of the movement in the direction of the periphery of the drum corresponds to the peripheral speed of the periphery of the drum, and the component of the movement in the direction of movement of the turns is approximately equal to the speed of transporting the turns. Due to the centro-40 bend forces of the rotating cooling drum, the cooling water forms a water jacket on the inner wall and moves with the speed of transporting turns of the wire along the helical inner profile in the axial direction along the cooling drum.

Due to the controlled outflow through the nozzle 8 located on the outlet side of the cooling drum of the compressed air opposing the flow of cooling water, it is possible to control the thickness of the cooling jacket water in the cooling drum and thereby to regulate the cooling intensity within known limits.

Invention Formula.

A device for cooling the wire, comprising a horizontally disposed, cylindrical body with nozzles for supplying water, characterized in that, in order to provide intensive cooling of the wire, the device is provided with a rotational drive connected to the body, the inner surface of which has spiral guides, This at the inlet of the casing are located at an angle of 10-20 nozzles for water supply, and at the outlet - oppositely directed nozzles of air supply.
