Ferric oxide removing device for surface of steel plate

Abstract

The invention relates to the field of plate processing, in particular to a ferric oxide removing device for the surface of a steel plate. The ferric oxide removing device comprises negative pressure boxes on the steel plate, rollers inside the negative pressure boxes and metal wires on the surfaces of the rollers. The negative pressure boxes are movably connected to the upper surface and the lower surface of the steel plate and are distributed symmetrically with respect to the steel plate. The bottoms of the left faces and the right faces of the negative pressure boxes are fixedly connected with rubber baffles. Negative pressure tubes are arranged at the tops of the negative pressure boxes, and the negative pressure tubes communicate with the insides of the negative pressure boxes. The rollers penetrate through the front faces and the rear faces of the negative pressure boxes, and are mounted in the negative pressure boxes. The metal wires are flexible steel wires. The ferric oxide removing device for the surface of the steel plate has the beneficial effects that through the design of the negative pressure boxes, flying of removed ferric oxide powder is prevented, the removing efficiency of the ferric iron is improved through the design of the flexible steel wires, the damage degree of the steel plate is reduced through the design of the rubber baffles, and the ferric oxide on the surface of the steel plate is removed and recycled.

Description

technical field [0001] The invention relates to the technical field of plate processing, in particular to a device for removing iron oxide on the surface of a steel plate. Background technique [0002] During the production process of the steel plate, a dense iron oxide layer is formed on the surface of the steel plate, which is tightly attached to the surface of the steel plate, which can prevent the interior of the steel plate from continuing to oxidize and protect the steel plate. However, due to the difference in the production process, a considerable part of the iron oxide layer It does not form a layered structure, but adheres to the surface of the steel plate in the form of flakes. Because there is a gap between the flake iron oxide and the steel plate, air and water invade this gap to oxidize and rust the steel plate, causing the steel plate to gradually rust until it is out of use. value.

[0002] During the production process of the steel plate, a dense iron oxide layer is formed on the surface of the steel plate, which is tightly attached to the surface of the steel plate, which can prevent the interior of the steel plate from continuing to oxidize and protect the steel plate. However, due to the difference in the production process, a considerable part of the iron oxide layer It does not form a layered structure, but adheres to the surface of the steel plate in the form of flakes. Because there is a gap between the flake iron oxide and the steel plate, air and water invade this gap to oxidize and rust the steel plate, causing the steel plate to gradually rust until it is out of use. value

[0003] At present, the traditional methods commonly used to remove flaky iron oxide include manual grinding and shot blasting. The manual grinding method has low efficiency and low standardization. High, the iron oxide scale or foreign matter embedded in the roller brush cannot be cleaned in time, which may scratch the lower surface of the steel plate or introduce new foreign matter into the steel plate surface during cleaning. To deal with this problem, it is necessary to constantly replace the roller brush or manually clean it, resulting in production efficiency. Underneath, the labor intensity of workers is high and the production cost is high
