Problems solved by technology

The disadvantage of the method described is that it is quite difficult technically to implement it and to calculate correctly when the wire will reach the desired temperature
[0009] It can also be seen that with all these liquid baths according to the state of the art, a fluid pump system is necessary which consumes a lot of energy

Embodiment Construction

[0025] The same and similar components still use the same symbols in different drawings.

[0026] The figures will now be described with reference to a water cooling device. Said description still applies to flushing the wire with a flushing liquid, or cooling the wire with any other cooling liquid.

[0027] A tank 1 filled with cooling water 2 is shown in FIGS. 1 and 2 . Above said groove, one or more steel wires 3 are drawn in the direction of travel indicated by arrow 4 . Common travel drives are schematically shown in the figure and are denoted by reference numerals 23 , 24 . Water flows in from the inlet 5 and flows out from the overflow port 6 . In the tank shown in the figure, the height of the water column is about 750 mm of water (7350 Pa). The overflow port 6 can communicate with the low inlet 5' through a heat exchanger not shown in the figure, so that the cooling water circulates.

[0028] Thus, the trough includes jets spraying a rising curtain of water. The...

Abstract

Disclosed is a device for cooling and / or rinsing at least one steel wire and / or tape, comprising means (23, 24) for conveying at least one steel wire and / or tape (3), a basin (1) which contains a cooling and / or rinsing liquid and is provided with outlets from which a certain number of successive liquid curtains (17) flow in a turbulent manner, the at least one steel wire and / or tape being conveyed through said liquid curtains (17), and means for adjusting the number of successive curtains to be penetrated by the at least one steel wire and / or tape according to the cooling and / or rinsing that is to be obtained.

Description

technical field [0001] The invention relates to a cooling and / or washing device for at least one steel wire and / or steel strip. Background technique [0002] Cooling liquids for steel wires are already known, which are used to harden steel wires in order to convert said steel wires. [0003] For example, wire toughening involving austempering, that is, rapid cooling of the wire to austenitic temperatures, just in the zone of pearlite formation, where the wire is placed in an almost isothermal manner to ensure that the austenitic The body is roughly completely decomposed and the steel stress is relieved. [0004] Quenching methods are known using lead or salt melts in which the steel wire to be cooled is immersed. Said method, although very effective, is currently banned due to its toxicity and environmental hazards. [0005] Quenching methods using aqueous baths (bains aqueux) are also known. Immersed in said laminar, non-turbulent water bath, a film of vapor forms aroun...
