Abstract
The utility model relates to an acid removal device for cold pickling lines, which comprises an air jet component arranged at the inlet of the pickling bath to remove acidic solutions on the rolled sheets and/or a wipe roll arranged on the surface of rolled sheets and moved up and down together with the rolled sheets. When the rolling mill is stopped, the rolled sheet is brought back to the inlet of the pickling bath where the acid solutions are cleaned by jetting and wiping. The costs required by the two methods are quite low.
Description
Technical field:
The utility model relates to a kind of device that is used to remove cold-reduced sheet surface acid washing lotion, especially is suitable for being provided in the deacidification device at cold-rolling pickling unit descaling bath inlet position.
Background technology:
Cold-rolling mill need be removed the iron scale on hot rolled plate surface through the overpickling stage when rolled plate, and the pickling stage generally includes these three processes of pickling, rinsing and oven dry, wherein, employed pickle is a hydrochloric acid in acid cleaning process, and hydrochloric acid very easily generates iron hydroxide with the iron reaction, be scale,, be subjected to the erosion of pickle to avoid steel plate so mainly be the pickle that is rolled surface of steel plate in order to remove in rinsing and baking stage.
But in the process of rolled plate; the intermittently phenomenon of shutdown can often appear in milling train; and when shutting down each time; the steel plate that is rolled can rest on positions such as descaling bath and rinsing tank usually, particularly rests on that part of steel plate in the rinsing tank, owing to also contain residual pickle in the rinsing tank; and its temperature is about 85 ℃; so steel plate can get rusty rapidly, and then seriously influenced the quality of steel plate after the erosion that is subjected to high-temperature rinsing liquid.
In the prior art, mainly be to utilize following two kinds of methods to eliminate scale: first cold water soak method when promptly shutting down in the pickling stage, will be rolled steel plate rapidly and put into the cold water immersion to avoid steel plate to get rusty; Second method is the deoxidier method; in the rinsing tank, add deoxidier when promptly taking place to shut down in the pickling stage; to reduce the chlorion in the tank; and then can reduce the growing amount of scale; but, owing to be by the mode of spray it to be cleaned when being rolled this steel plate by the washings groove location, and steel plate normally is suspended on the water surface of rinsing tank; so, want to realize quite difficulty of above-mentioned two kinds of operations.
Summary of the invention:
The purpose of this utility model provides a kind of utilization and will be rolled steel plate back the mode of clearing up the surface of steel plate pickle again in descaling bath inlet position and solve the deacidification device that steel plate is etched problem when shutting down.
The utility model proposed be provided in deacidification device on the cold-rolling pickling unit comprise be installed in descaling bath inlet position be used to remove the jet assembly that rolls plate surface acid solution and/or be installed in roll the plate surface and can drive and roll the squeeze roll that plate moves up and down together.
Described jet assembly comprises that is installed in a descaling bath inlet position pipe fitting, and is provided with on each pipe fitting towards rolling the nozzle of plate surface direction.Described squeeze roll is to be arranged on to be rolled the steel plate pair roller of both sides up and down.
The deacidification device that the utility model proposed has adopted jet assembly and the squeeze roll that is arranged on descaling bath inlet position; when milling train is shut down; can back descaling bath inlet position with rolling plate; by jet and extract the acid solution that dual mode is easy to roll on the plate and wash, and how many costs this dual mode can't increase.
Description of drawings:
Accompanying drawing 1 is the surface structure schematic diagram of an embodiment of deacidification device.
The specific embodiment:
Referring to Fig. 1, this figure provides the overall appearance structure of the embodiment of deacidification device that the utility model proposes.This deacidification device comprises jet assembly 1 and squeeze roll 2, and jet assembly 1 and squeeze roll 2 are installed in the descaling bath inlet position on the cold-rolling pickling unit.Jet assembly 1 is made of pipe fitting 11, and is provided with on each pipe fitting 11 towards rolling the nozzle 12 of plate surface direction, and squeeze roll 2 constitutes by being arranged on the pair roller that is rolled steel plate 3 upper and lower surfaces.
When milling train is shut down; the steel plate that is rolled that will exceed descaling bath inlet position is earlier backed descaling bath inlet position; when refunding,, get rusty to avoid steel plate by the acid solution of jet assembly 1 to surface of steel plate winding-up gases at high pressure and squeeze roll 12 dual modes removing surface of steel plate.
Claims (3)
1, be provided in deacidification device on the cold-rolling pickling unit, it is characterized in that: this deacidification device comprise be installed in descaling bath inlet position be used to remove the jet assembly that rolls plate surface acid solution and/or be installed in roll the plate surface and can drive and roll the squeeze roll that plate moves up and down together.
2, deacidification device according to claim 1 is characterized in that: described jet assembly comprises that is installed in a descaling bath inlet position pipe fitting, and is provided with on each pipe fitting towards rolling the nozzle of plate surface direction.
3, deacidification device according to claim 1 is characterized in that: described squeeze roll is to be arranged on to be rolled the steel plate pair roller of both sides up and down.
