A process for producing a galvanization apparatus for producing a medium-width strip steel as shown in fig. 1, the process comprising the steps of:
A1, placing strip steel: placing strip steel to be galvanized into a galvanizing pool 1 for galvanizing;
A2, zinc liquid outlet: when the strip steel is extracted from the zinc liquid, the drop of the zinc liquid is reduced by controlling the speed and the gesture;
A3, zinc slag treatment: during the galvanization process, zinc residues are generated, and are collected and treated through the zinc residue flushing assembly, so that the zinc residues are prevented from adhering to the strip steel;
A4, quality inspection: the thickness, uniformity, appearance quality and the like of the strip steel galvanized layer are strictly checked, and the product is ensured to accord with relevant standards.
As a technical optimization scheme of the invention: the step A3 specifically comprises the following steps:
the control pushing piece 13 starts to shrink so as to drive the piston plate 12 to absorb liquid;
The control pusher 13 activates the push-out to push the piston plate 12 to push the liquid.
As a technical optimization scheme of the invention: the density of the zinc slag is less than that of the zinc plating solution.
The working principle of the invention is as follows:
The strip steel to be galvanized is placed at a proper position, galvanizing is started after preparation is completed, the thickness of the galvanized strip steel is detected in real time through a detection unit, so that the requirements are met, in the galvanizing process, part of zinc slag floats upwards because the density is smaller than that of zinc liquid and is adhered to the strip steel after the strip steel is separated from the zinc liquid, so that a driving assembly drives a stirring plate 4 to reciprocate below the flat surface of the strip steel in the strip steel galvanizing process, further, the reciprocating pushing action of the stirring plate 4 is facilitated, liquid in the middle area of the zinc liquid is pushed to the edges of two sides of a galvanizing pool 1, the zinc slag can be effectively prevented from being shielded by the flat areas on the surface of the strip steel, the zinc slag can be ensured to float to the surface smoothly, the follow-up collection and treatment are facilitated, and the purity of the zinc liquid and the efficiency of the galvanizing process are improved;
Then, when the strip steel is conveyed by the conveying roller 3 and separated from the zinc plating solution, the zinc slag flushing assembly is designed to help guide and remove the dross at the contact edge of the strip steel and the molten zinc solution, the zinc slag flushing assembly firstly captures and collects zinc slag in the area to prevent the zinc slag from adhering to the surface of the strip steel when the strip steel rises out of the surface of the zinc solution, a storage mechanism arranged in the zinc slag flushing assembly temporarily holds the liquid containing the zinc slag, then the stored liquid is directionally sprayed to the junction area of the strip steel and the zinc solution, and the zinc slag is intercepted by the built-in interception assembly, so that the sprayed liquid is only the zinc plating solution, thereby helping to utilize the impact force generated by spraying to wash away the residual zinc slag at the junction of the strip steel and the zinc solution, forcing the residual zinc slag to flow towards the wall of the zinc plating tank 1, thereby helping to effectively avoid the strip steel from being polluted by the zinc slag at the zinc outlet ring joint, and helping to ensure the cleanliness of the surface of the strip steel, improve the quality and appearance of galvanized finished products, and reduce the need of subsequent treatment.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made therein without departing from the spirit and scope of the invention, which is defined by the appended claims.
