Definitions
- the invention relates to a device for treating metallic extrudates, in particular for pickling rolled strip that can be transported through a treatment channel and can be turbulently irradiated with treatment liquid from nozzles, wherein the liquid jets at the channel entrance are set in the strand transport direction and at the channel exit are opposite to the strand transport direction, to prevent the treatment liquid from draining off quickly.
- Such a device is known from DE-OS 29 11 701.
- This design aims at the difficulties with the use of pinch rollers and thus a transfer to avoid treatment liquid between individual tanks.
- there support or guide rollers are to be replaced by other elements.
- this construction is based on elongated rectangular treatment chambers and on the other hand, treatment nozzles are parallel and perpendicular to the strand transport direction arranged.
- deflectors are over and arranged under the strand material, which is a better spraying of the strand material should effect.
- the measures outlined are exclusively aimed at a further turbulence and turbulence and represent purely mechanical Procedures. A further chemical effect is not intended still intended.
- the invention is based, in addition to the physical effects of the task Turbulence the chemical effects of the treatment liquid and possibly even to improve the surface condition of the strand material in the sense of increasing the throughput and extending treatment to critical steel grades.
- the object is achieved according to the invention in that the treatment channel is formed on the top by means of lined up floating bodies that facing the continuous material, each with one or more, distributed area Heat exchangers are provided, whose thermal energy on the treatment liquid and / or the continuous material is transferable.
- An additional thermal entry increases the chemical effects by making the treatment liquid on faster the desired reaction temperature is brought and thus earlier and more intensely responding.
- a further improvement in the efficiency of such devices is combined achieved with chemical reactions in that the area-distributed Heat exchangers are assigned flow baffles that protrude downward serve to mix the treatment liquid flow.
- the flow baffles between two heat exchangers are advantageously to the side of a heat exchanger and / or in front of or in front of a pair of Heat exchangers arranged. This creates a particularly intensive vortex the treatment liquid achieved.
- the transfer of the thermal energy to the extrudate and / or the treatment liquid is carried out particularly intensively by turning the heat exchanger off at the There are heating pipes or heating plates laid on the underside of the float.
- heating pipes are serpentine Heating combs are installed. This means a high use of space and a high one Heat allocation of the available base area connected.
- Another embodiment provides that the heating pipes made of PVDF or PTFE manufactured and operated with water vapor at approx. 130 - 135 ° C. This training ensures good heat resistance at relatively high temperatures.
- the floating bodies with the heat exchangers are each at a distance from one surrounding, open lid housing facing the floating body attached are.
- the cover housing with several spacers the floating body is connected.
- the handling of the float, the heat exchanger and the cover housing is further facilitated in that the lid housing together with the Float can be lifted out using lifting gear or a hydraulic device or can be placed on the treatment chamber. This allows the heat exchanger easily and quickly replaced or repaired outside the device become.
- the floating body is made of plastic, whereby a considerably light construction can be created.
- the extrudate 1 is mixed with treatment liquid 5 from nozzles 6
- Liquid jets 7 are irradiated in such a way that a turbulent treatment liquid flow 5a exists.
- the liquid jets 7 are at the channel entrance 8 in the strand transport direction 9 set and at channel exit 10 to the strand transport direction 9 in the opposite direction, so that the treatment liquid 5 flows off quickly the respective treatment chamber 3 and 4 is at least inhibited.
- the continuous stock 1 lies within the treatment chambers 3, 4 on sliding blocks 3a and 4a.
- the treatment channel 2 is lined up on its upper side 2a Float 11 formed, facing the strand 1, each with individual or several, surface-distributed heat exchangers 12 are equipped, their thermal energy is transferred to the treatment liquid 5 and / or the strand 1.
- the treatment liquid 5 entering with the desired entry temperature intensifies the chemical reaction between the surface of the continuous material 1, in particular of rolled strip 1a, and leads to more intensive cleaning processes and thus optimizing the process and increasing throughput.
- the turbulence also contributes to these processes, so that in combination with the heated treatment liquid 5 brought a significant improvement of the process takes place.
- Distributed flow baffles ensure this effect 13, which are assigned to the surface-distributed heat exchangers 12, downwards protrude and the mixing of the treatment liquid flow 5a considerably strengthen.
- the flow guide plates 13 are between two Heat exchangers 12, laterally from a heat exchanger 12 and / or in front of one or arranged in front of a pair of heat exchangers 12 in the strand transport direction 9.
- the heat exchangers 12 each consist of the underside 11a of the floating body 11 laid heating pipes 14 or heating plates.
- the heating tubes 14 are laid in a serpentine shape to the heating honeycomb 15 and are located in closed cutouts 11b of the float 11.
- the heating pipes are off PVDF (polyvinylidene fluoride) or PTFE (polytetrafluoroethylene) manufactured and lead Steam from approx. 130 - 135 ° C.
- the floats 11 are at a distance from the heat exchangers 12 16 to a surrounding open lid housing facing the floating body 11 17 connected.
- the distance 16 is between by means of several spacers 18 the float 11 and the lid housing 17 determined.
- the lid housing 17 is a unit together with the floating body 11 and the heat exchangers 12 by means of lifting gear 19 or by means of a hydraulic device can be lifted out or placed on the treatment chamber 3 or 4 again.
- the Floating body 11 can be made of plastic to have a low weight and any disruptive vapors from the treatment liquid 5 to resist and intercept them.
- the hot steam is directed in the direction 20 through a hose connection 21 and through the float 11 in the heating tubes 14 and back in the circuit.
