Abstract
The present invention discloses a kind of mixing descaling bath, including cell body, groove lid, and the both sides of cell body set squeeze roll, and the bottom of cell body sets many places lug boss, and multiple submergence rollers are also set up inside cell body, and submergence roller height is different；Strip is moved by squeeze roll drives edge submergence roller；Cell body of the present invention is made up of PPR acid-proof base materials, adds the mixed solution of nitric acid, hydrofluoric acid and water, belt steel surface iron scale is cleaned by mix acid liquor concentration regulation in control flume, so as to reach the good cleaning performance of belt steel surface.
Description
Technical field
The present invention relates to chemical field, specifically a kind of descaling bath.
Background technology
On the surface of the cold-rolled strip of stainless steel, because oxidation annealing process can generate oxide skin, therefore, it is necessary to remove
The impurity such as belt steel surface iron scale；In production practices, typically solves the technical problem using pickling hydrochloric acid washing trough, generally
Pickling slot structure be a flat cell body, steel band is moved from one end to other end, and in the process, injection in groove
Pickling salt (sodium sulphate) solution, battery lead plate and strip form electrochemical circuit, miscellaneous so as to remove belt steel surface iron scale etc.
Matter.The shortcomings that structure is：On the one hand because the pickling slot length is larger, it is necessary to very big space；On the other hand, cell body is grown
Spend it is limited, steel band by cell body time it is shorter, often effect is bad.
The content of the invention
In order to solve the above technical problems, it is an object of the invention to provide a kind of more preferable descaling bath of pickling effect, and phase
Smaller to space-consuming, concrete technical scheme is：
One kind mixing descaling bath, including cell body, groove lid, the both sides of cell body set squeeze roll, and the bottom of cell body sets many places
Lug boss, multiple submergence rollers are also set up inside cell body, and submergence roller height is different；Strip is moved by squeeze roll drives edge submergence roller；
The lug boss is irregular triangular pyramid type；The cell body is divided into two parts, two-part intersection along the steel band direction of motion
Adjusting-flow board is set, and two parts of cell body, which are set, ensures that the vigorous reaction by gradually becomes the shallower reaction of later ratio；
The cell body bottom plate sets turbulent blade；Lug boss and turbulent blade make pickling salting liquid form rotary motion in cell body, just
In the uniform of concentration, reaction efficiency is improved.It is an advantage of the invention that：
Because submergence roller height is different, therefore, stroke of the steel band in pickle is added；Cell body bottom is provided with many places
Lug boss, and add turbulent blade so that pickling salting liquid forms local rotation, advantageously in the equal of pickling salting liquid
It is even, the uneven of concentration is avoided, to be preferably electrochemically reacted；And two parts of cell body are set, ensured by
Vigorous reaction gradually become the shallower reaction of later ratio, improve the surface quality of steel band.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Illustrate the present invention below in conjunction with the accompanying drawings, as shown in figure 1, the present invention include cell body 2, groove lid 8, the two of cell body 2
Side sets squeeze roll 1, and the bottom of cell body 2 sets many places lug boss 3, also sets up multiple submergence rollers 6 inside cell body 2, submergence roller 6 is high
Degree is different；Strip 7 is moved by the drives edge submergence roller 6 of squeeze roll 1.
The lug boss 3 is irregular triangular pyramid type.
The cell body 2 is divided into two parts along the direction of motion of steel band 7, and two-part intersection sets adjusting-flow board 9.
The bottom plate of cell body 2 sets turbulent blade 5.
The effect of the critical piece of the present invention is as follows：
Squeeze roll 1：The effect that support strip 7 is driven, seals cell body and extract belt steel surface liquid.
Submergence roller 6：Strip is set to be immersed in tank liquid.
Lug boss 3 and turbulent blade 5：Pickling salting liquid is formed rotary motion in cell body, be easy to the uniform of concentration, carry
High reaction efficiency.
Cell body of the present invention is made up of PPR acid-proof base materials, adds the mixed solution of nitric acid, hydrofluoric acid and water, passes through control
Mix acid liquor concentration is adjusted to be cleaned to belt steel surface iron scale in groove, so as to reach the good cleaning effect of belt steel surface
Fruit.
Claims (1)
1. one kind mixing descaling bath, including cell body, groove lid, it is characterised in that：The both sides of cell body set squeeze roll, the bottom of cell body
Many places lug boss is set, multiple submergence rollers are also set up inside cell body, submergence roller height is different；Strip is submerged by squeeze roll drives edge
Roller moves；The lug boss is irregular triangular pyramid type；The cell body is divided into two parts along the steel band direction of motion, two-part
Intersection sets adjusting-flow board, and it is shallower that two parts of cell body set the vigorous reaction for ensureing by gradually become later ratio
Reaction；The cell body bottom plate sets turbulent blade；Lug boss and turbulent blade make pickling salting liquid form rotation fortune in cell body
It is dynamic, it is easy to the uniform of concentration, improves reaction efficiency.
