Abstract
The invention discloses a surface watermark control device for an acid pickling of a hot-rolled strip steel and a watermark control method, the two of which are applied to preventing marks from being formed on the surface of the strip steel. The device comprises an acid pickling tank and a rinse tank, wherein a plurality of groups of wiping rolls arranged at intervals are arranged between the acid pickling tank and the rinse tank; a support is arranged between one group of wiping rolls corresponding to the outlet of the acid pickling tank, and the rinse tank; a plurality of nozzles for spraying acidic rinsing water to the strip steel are mounted on the support; the nozzle are connected with a water source through a water delivery pipeline. The rinse tank can be used as the water source; a rinsing water pump is mounted on the water delivery pipeline. Besides, the plurality of nozzles are arranged above and under the strip steel, respectively. The method is characterized in that the acidic rinsing water is sprayed to the surface of the strip steel mainly through the nozzles and the amount of spraying is 2-30 ml/m<2>.
Description
Technical field
The present invention relates to a kind of hot rolled strip pickled surface watermark control device of hot rolled strip production field application and the watermark control method that adopts this device.
Background technology
In hot rolled strip is carried out to acid cleaning process, after hot rolled strip carries out pickling in pickling tank, the residual part acid solution of belt steel surface, after the device extruding such as squeezing roller purge, the remaining acid solution in surface can be attached to belt steel surface with the solid salt formed that reacts with steel, and this solid salt in rinse tank, easy cleaning is unclean clearly, at product surface, the marking appears finally, affect quality product.
Summary of the invention
The technical problem that the present invention solves is to provide a kind of for preventing that the hot rolled strip pickled surface watermark control device of the marking from appearring in belt steel surface.
The technical solution adopted for the present invention to solve the technical problems is: hot rolled strip pickled surface watermark control device, comprise pickling tank and rinse tank, be provided with the spaced band steel drying installation of many groups between pickling tank and rinse tank, be provided with bracing frame between one group of band steel drying installation of the outlet correspondence of pickling tank and rinse tank, on bracing frame, be equipped with a plurality ofly for to spray the nozzle of acidic rinse water with steel, nozzle is connected with water source by water pipeline.
Further: described water source is rinse tank, and the rinsing water pump is installed on water pipeline.
Further: described a plurality of nozzles are separately positioned on the above and below with steel.
Further: band steel drying installation is squeezing roller.
The present invention also provides a kind of watermark control method, is specially: adopt above-mentioned watermark control device, by nozzle, to belt steel surface, spray acidic rinse water, the sprinkling amount is 2～30ml/m
2.Adopt aforesaid method, the belt steel surface visual inspection after final rinsing is 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, realization is in the residual hydrochloric acid cleaning to belt steel surface, prevent that belt steel surface is because directly contacting the rear watermark that forms with air, prevent that the purpose of the marking from appearring in belt steel surface thereby reach, guaranteed hot rolling acid-cleaning plate face quality.
The accompanying drawing explanation
The schematic diagram that Fig. 1 is hot rolled strip pickled surface watermark control device of the present invention;
In figure, be labeled as: pickling tank 1, band steel drying installation 2, nozzle 3, bracing frame 4, water pipeline 5, rinsing water pump 6, rinse tank 7, band steel 8.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As shown in Figure 1, hot rolled strip pickled surface watermark control device, comprise pickling tank 1 and rinse tank 7, be provided with the spaced band steel drying installation 2 of many groups between pickling tank 1 and rinse tank 7, be provided with bracing frame 4 between one group of band steel drying installation of the outlet correspondence of pickling tank 1 and rinse tank 7, on bracing frame 4, be equipped with a plurality ofly for to spray the nozzle 3 of acidic rinse water with steel, nozzle 3 is connected with water source by water pipeline 5.Above-mentioned band steel drying installation 2 can be squeezing roller, blow device or other existing drying installation.
Water source is acidic rinse water, namely containing sour rinse water.Water-spraying amount is according to 2～30ml/m
2it is the most reasonable to be controlled.The water yield is very few or too much, and final control effect is all undesirable.By to belt steel surface, spraying acidic rinse water, and, under the effect with steel drying installation 2, can be uniformly distributed one deck containing acid rinse water at belt steel surface, prevent that belt steel surface is because directly contacting the rear watermark that forms with air.Also can make with steel more thorough in the interior rinsing of follow-up rinse tank 7.
For water saving, realize the resource recycling, as shown in Figure 1, described water source is rinse tank 7, and rinsing water pump 6 is installed on water pipeline 5.Can reuse like this rinse water in rinse tank 7, because the rinse water in rinse tank 7 itself can form acidic rinse water containing acid after rinsing the band steel, therefore can utilize the rinse water in rinse tank 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 shown in Figure 1, described a plurality of nozzles 3 are separately positioned on the above and below with steel 8.
Embodiment:
Hot rolled strip pickled surface watermark control device, comprise pickling tank 1 and rinse tank 7, be provided with the spaced squeezing roller of many groups between pickling tank 1 and rinse tank 7, be provided with bracing frame 4 between one group of squeezing roller of the outlet correspondence of pickling tank 1 and rinse tank 7, on bracing frame 4, be equipped with a plurality of for the nozzle 3 to steel sprinkling acidic rinse water, nozzle 3 is connected with rinse tank 7 by water pipeline 5, rinsing water pump 6 is installed on water pipeline 5, and described a plurality of nozzles 3 are separately positioned on the above and below with steel 8.
