Problems solved by technology

[0009] For this reason, in the liquid removal nozzle 22 of the strip steel material 21 of the above-mentioned conventional example, the liquid removal on the reverse side of the burr tends to be insufficient, and in order to avoid contact with the burr, the strip steel material 21 has to be The inlet of the ejection opening 24 is enlarged to a size above the required
As a result, there is a problem that a large amount of gas (air) is always used regardless of the original purpose

Embodiment

[0042] In the actual manufacturing process of flux cored wire, it is installed in the first stage of the degreasing device Figure 6 In the liquid removal nozzle 22 of the conventional example shown in , the air consumption and the noise that can carry out the liquid removal of the steel strip are measured by actually running the steel strip. In the same actual manufacturing process as described above, in such as image 3 , 4 4-stage setup in degreasing unit shown figure 1 , 2 In the shown air nozzle 1 of the present invention, the air consumption and noise that can remove the liquid from the strip were measured by running the strip under the same conditions as in the conventional example.

[0043] As a result, the air consumption in the case of using the strip liquid removal device of the present invention can be confirmed to save about 1 / 3 of the air consumption at the same air pressure compared with the strip liquid removal nozzle of the conventional example. Amount, a...

Abstract

The invention is a liquid removing device has an air nozzle, the air nozzle has an injection hole arranged by a plurality of thin holes, the air injection direction generated by the air nozzle is the direction sloping at opposite upper and lower sides relative to the travelling direction of the steel band. The device is suitable for the manufacturing procedure of a flux-cored wire, the washing liquid attached on the surface of the cleaned steel band can be removed, according to the device, the air consumption for removing the liquid can be reduced.

Description

technical field [0001] The present invention relates to a liquid removal device, which is suitable for use in the manufacturing process of flux-cored welding wire having the process of pulling out coiled steel strip (hereinafter also referred to as steel strip) and forming it into a tubular shape after cleaning. The washing liquid adhering to the surface of the strip is continuously removed during the progress of the steel strip to the forming process. Background technique [0002] Therefore, for an overview of the usual manufacturing process of flux-cored wire, refer to the attached Figure 5 To illustrate. Figure 5 It is a block diagram showing the outline of the manufacturing process of the flux cored wire. [0003] First, the steel strip (raw material wire) wound on the bobbin is drawn out and supplied to the manufacturing process (drawing-out process S1). After the rust preventive oil adhering to the supplied steel strip is sprayed with a liquid such as water or hot w...
