Foreign material removal device

Abstract

The present invention relates to a foreign material removal device for removing foreign material attached to the surface of a rotating roll such as a strip transfer roll, and the foreign material removal device comprises: a housing disposed in the width direction of an object; a foreign material separating means provided at the housing and separating the foreign materials from the surface of the rotating object; and an air guide unit disposed at the housing so as to form a gap from the object, and supplying air to the gap so as to guide, to the inside of the housing, the foreign materials separated from at least the object. Therefore, the present invention can obtain an effect of completely removing the foreign material with respect to the entire width direction of the strip transfer roll.

Description

technical field [0001] The present invention relates to a foreign matter removing device, and more particularly, to a foreign matter removing device for removing foreign matter adhering to the surface of a rotating roll such as a strip transfer roll. Background technique [0002] A strip steel, which is generally rolled into a thin plate shape, is supported by a plurality of rolls and continuously moved while passing through various processes to be manufactured into a product in a condition required by a user. [0003] Here, the transfer of the steel strip to each process is performed by a transfer facility composed of a plurality of transfer rollers. [0004] However, since this type of transfer roller is made of polyurethane or the like, many foreign substances adhere or stick to the surface after a certain period of time. [0005] Such foreign matter also causes a follow-up problem that dents (Dents) such as concave-convex defects are generated on the surface of the stee...

Problems solved by technology

[0007] However, when foreign matter is removed by conventional methods, foreign matter such as the magnesium oxide powder cannot be completely removed from the surface of the transfer roller.

[0008] In addition, a part of the foreign matter detached from the transfer roll falls on the upper surface of the transferred steel strip and contacts the transfer roll again, resulting in the defect that grooves are formed on the surface of the transfer roll due to the foreign matter.
