Abstract
The invention discloses a kind of hot-strip pickled surface watermark control device and watermark control method, for preventing that the marking from appearring in belt steel surface. This device comprises descaling bath and potcher, between descaling bath and potcher, be provided with the spaced squeeze roll of many groups, between one group of squeeze roll of the outlet correspondence of descaling bath and potcher, be provided with bracing frame, on bracing frame, be provided with multiplely for the nozzle to spray acidic rinse water with steel, nozzle is connected with water source by water pipeline. Above-mentioned water source can be potcher, and rinsing water pump is installed on water pipeline. Described multiple nozzle is separately positioned on the above and below with steel. The method is mainly to spray acidic rinse water by nozzle to belt steel surface, and sprinkling amount is 2～30ml/m2。
Description
Technical field
The present invention relates to a kind of hot-strip pickled surface watermark control device of hot-strip production field application and adopt this dressThe watermark control method of putting.
Background technology
Hot-strip is carried out in acid cleaning process, hot-strip carries out after pickling in descaling bath, the residual part acid of belt steel surfaceLiquid, after the device extruding such as squeeze roll purge, the remaining acid solution in surface can be adhered to the solid salt forming that reacts with steelAt belt steel surface, and this solid salt in potcher, easy cleaning is unclean clearly, finally there is the marking at product surface, impact produceProduct quality.
Summary of the invention
The technical problem that the present invention solves is to provide a kind of for preventing that the hot-strip pickled surface watermark of the marking from appearring in belt steel surfaceControl device.
The technical solution adopted for the present invention to solve the technical problems is: hot-strip pickled surface watermark control device, comprises acidWashing trough and potcher, be provided with the spaced band steel drying device of many groups between descaling bath and potcher, the outlet of descaling bath is rightBetween one group of band steel drying device of answering and potcher, be provided with bracing frame, on bracing frame, be provided with multiple for spraying acid to band steelThe nozzle of property washings, nozzle is connected with water source by water pipeline.
Further: described water source is potcher, rinsing water pump is installed on water pipeline.
Further: described multiple nozzles are separately positioned on the above and below with steel.
Further: band steel drying device is squeeze roll.
The present invention also provides a kind of watermark control method, is specially: adopt above-mentioned watermark control device, by nozzle to band steelSurface sprinkling acidic rinse water, sprinkling amount is 2～30ml/m2. Adopt said method, the belt steel surface naked eyes after final rinsing are seenExamine less than watermark.
The invention has the beneficial effects as follows: device of the present invention can be uniformly distributed one deck containing sour rinse water at belt steel surface, realizes rightWhen the residual hydrochloric acid cleaning of belt steel surface, prevent that belt steel surface from, because directly contacting the rear watermark that forms with air, preventing thereby reachThere is the object of the marking in belt steel surface, has guaranteed hot rolling acid-cleaning plate face quality.
Brief description of the drawings
Fig. 1 is the schematic diagram of hot-strip pickled surface watermark control device of the present invention;
In figure, be labeled as: descaling bath 1, band steel drying device 2, nozzle 3, bracing frame 4, water pipeline 5, rinsing water pump 6,Potcher 7, band steel 8.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As shown in Figure 1, hot-strip pickled surface watermark control device, comprises descaling bath 1 and potcher 7, descaling bath 1 withBetween potcher 7, be provided with the spaced band steel drying device 2 of many groups, one group of band steel of the outlet correspondence of descaling bath 1 is dryBetween device and potcher 7, be provided with bracing frame 4, on bracing frame 4, be provided with multiple for to steel sprinkling acidic rinse waterNozzle 3, nozzle 3 is connected with water source by water pipeline 5. Above-mentioned band steel drying device 2 can be squeeze roll, blow device orOther existing drying device.
Water source is acidic rinse water, namely containing sour washings. Water-spraying amount is according to 2～30ml/m2It is the most reasonable to control.The water yield is very few or too much, and final control effect is all undesirable. By spraying acidic rinse water to belt steel surface, and dry at band steelUnder the effect of dry device 2, can be uniformly distributed one deck containing acid rinse water at belt steel surface, prevent that belt steel surface is because directly connecing with airForm after touch watermark. Also can make with steel more thorough in the interior rinsing of follow-up potcher 7.
For using water wisely, realize resource recycling, as shown in Figure 1, described water source is potcher 7, on water pipeline 5Rinsing water pump 6 is installed. Can reuse like this washings in potcher 7, because the washings in potcher 7 were rinsingAfter band steel, itself can, containing acid, form acidic rinse water, therefore can utilize washings in potcher 7 to supply water for said nozzle 3.
On the basis of the above, for the ease of band steel upper surface and lower surface are sprayed to acidic rinse water uniformly comprehensively, as Fig. 1 instituteShow, described multiple nozzles 3 are separately positioned on the above and below with steel 8.
Embodiment:
Hot-strip pickled surface watermark control device, comprises descaling bath 1 and potcher 7, between descaling bath 1 and potcher 7Be provided with the spaced squeeze rolls of many groups, between one group of squeeze roll of the outlet correspondence of descaling bath 1 and potcher 7, be provided with and prop upSupport 4, is provided with multiplely for the nozzle 3 to spray acidic rinse water with steel on bracing frame 4, nozzle 3 is by water pipeline 5Be connected with potcher 7, rinsing water pump 6 is installed on water pipeline 5, described multiple nozzles 3 are separately positioned on upper with steel 8Side and below.
