Definitions
- the present invention relates to a device for cooling and / or rinsing at least one steel wire and / or ribbon.
- Son cooling baths have been known for a long time for quenching steel wires in order to obtain a transformation of the latter.
- This fairly complex device does not allow fine adjustment of the cooling temperature, requires the use of a high pressure circulation pump and a circuit of pipes, tanks and sprinklers which are susceptible to sealing problems.
- Aqueous baths are also known which have as their object the rinsing of steel wires, for example before and / or after an acid pickling bath.
- the present invention aims to develop a simple and inexpensive device which overcomes the aforementioned drawbacks.
- a device for cooling and / or rinsing at least one steel wire and / or ribbon comprising
- this device further comprising
- This device has the advantage that the contact between the coolant and the wire or ribbon is direct, without the possibility of formation of a vapor film around the wire or ribbon, film where the heat exchange is much less favorable.
- the coolant does not have time to form a film of vapor around the wire and exchange liquid thermal steel wire remains excellent.
- the process offers the advantage of being able to stop the cooling at any desired temperature by a simple determination of the number of curtains necessary. This is particularly important in the case of patenting steel wires, where it is necessary to avoid too rapid quenching which gives rise to the appearance of martensite in the steel, which is to be avoided in most cases.
- the tank is arranged below said at least one thread and / or ribbon in movement and the device further comprises means for projecting the curtains of said liquid in a turbulent upward flow.
- the coolant is sprayed under pressure at the like a continuous geyser and therefore very turbulent.
- the curtains with upward turbulent flow have a top and, from said top and at least on one side of each curtain with upward turbulent flow, a drop of turbulent flow liquid through which the said at least one thread also travels. and / or steel tape.
- the wire can therefore pass through three successive streams of liquid with turbulent flow, one ascending and the other two descending, which makes the subsequent cooling or rinsing very effective. It is of course also possible to provide a tank arranged above the scrolling wires and the fall or projection of curtains of coolant from the top.
- the means for projecting the device comprise means for supplying pressurized gas bubbles into a lower part of the tank and means for forcibly guiding bubbles which entrain the liquid upward in the form of curtains of liquid with turbulent upward flow.
- the means for supplying pressurized gas bubbles into a lower part of the tank Preferably use an inert gas with respect to steel, and in particular air.
- the air bubbles under pressure entrain the coolant and simultaneously make its flow turbulent, which promotes the desired direct heat exchange.
- the upward projection by air bubbles does not require an expensive energy expenditure and it makes it possible to avoid any pumping system for the coolant.
- the coolant and / or rinse aid can be any suitable liquid, water, lead, liquid salt, a polymer, oil, and in particular water, because all the disadvantages encountered by the use of water in the prior art can be overcome by the process according to the invention.
- the device is therefore in the form of a simple device which is easy to control and adjust and it allows consumption. only non-polluting and inexpensive materials, i.e. compressed air and cooling water.
- FIG. 1 represents a view in longitudinal section of a device for cooling and / or rinsing steel wires and / or ribbons according to the invention.
- FIG. 2 represents a plan view from above of FIG. 1.
- FIGs 1 and 2 there is shown a tank 1 containing cooling water 2. Above this tank scrolls one or more steel wires 3 in a direction of travel indicated by the arrow 4. Means current scrolling drive systems are represented schematically by the references 23 and 24.
- the water can be supplied by an inlet 5 and be discharged from the top by an overflow 6.
- the column height d water is approximately 750mm H 2 0 (7350 Pa).
- the overflow 6 can be in communication with a lower inlet 5 ′, by means of a heat exchanger not shown, so as to put the cooling water into circulation.
- the tank also includes means for projecting rising water curtains.
- These projection means include air supply ducts 7 to 9 arranged at the bottom of the tank parallel to one another and transversely to the direction of travel of the wires and / or ribbons.
- Each of these conduits is connected, through corresponding openings in the tank and by means of fittings 10 to 12, to a distributor duct 13 supplied with pressurized air by a fan 14.
- a shut-off valve 22 On each fitting 10 to 12 is provided a shut-off valve 22 which makes it possible to adjust the supply of pressurized air to the conduits 7 to 9 and to put them on or off as required.
- the air bubbles entrain the water of the tank during their ascent and expel a curtain of turbulent water 17 upwards.
- a pressure of the order of 1000 mm of H 2 0 (9806 Pa) for example the air bubbles entrain the water of the tank during their ascent and expel a curtain of turbulent water 17 upwards.
- the top of the water curtain it can be split in two and form two turbulent waterfalls 18 and 19 that the wire to be cooled must also pass through.
- the pairs of guide plates 15, 16 can be arranged sufficiently tightly in their succession so that the waterfalls of two neighboring curtains can cross. Of in this way, the wire runs continuously in water, and yet there is never the possibility of the formation of a film of water vapor around the wire.
- a cover 20 which closes the tank upwards and which presents deflectors 21 to orient the direction of the waterfalls 18 and 19.
- TTT curves transformation, temperature, time
- the wires are located opposite the nose of the S-curves, that is to say at a temperature corresponding to the minimum incubation time, to pass through these curves, which makes it possible to avoid disturbances that could influence the structure of the steel.
