Description

SHOT BLAST {SHOT BLAST}

The present invention relates to a shot blast for shoveling an oxide scale layer formed on a surface of a strip by projecting a short ball to an annealed strip.

An oxide scale layer is formed on the surface of the strip annealed in the annealing furnace.

In order to remove the oxidized scale layer thus formed from the surface of the script, the strip is pickled with an acid solution in a pickling apparatus.

Shot blast is used to facilitate removal of the oxide scale layer by the pickling treatment of the strip in such a pickling apparatus.

In the shot blast, a short ball, which is a small iron ball, is projected onto the annealed strip in the annealing furnace. Thereby, the oxide scale layer formed on the surface of the strip is crushed, and the pickling solution can easily penetrate into the oxide scale layer in the pickling treatment of the strip in the pickling apparatus. Further, removal of the oxide scale layer from the surface of the strip by the pickling treatment in the pickling apparatus can be made easier.

On the other hand, the width of the annealed strip is not constant. Therefore, depending on the width of the strip, the width of the projection of the short ball must also vary.

In the conventional shot blast, the operator manually adjusts the projection width of the shot ball while checking the width of the strip with the naked eye.

Therefore, when adjustment of the projection width of the short ball by the operator is not smooth, there is a portion of the strip on which the oxide scale layer is not broken due to the short ball. Then, in the pickling apparatus, there was a part where the pickling treatment was not performed, that is, the oxide scale layer was not removed from the other parts.

In this way, strips having portions where the oxide scale layer was not removed had to be reprocessed.
