Copper and copper alloy strip hot-rolling online surface scale collection device

Abstract

The invention discloses a copper and copper alloy strip hot-rolling online surface scale collection device. The device comprises a hot-rolling mill rack. A pair of rollers which are arranged in an up-and-down manner are horizontally arranged on the hot-rolling mill rack. The upper roller and the lower roller are connected to the upper surface and the lower surface of a strip respectively in a pressed manner. The rollers are provided with a cooling spraying pipeline used for spraying cooling mediums to the rollers. The cooling spraying pipeline is connected with a circulation pool through a conveying pipeline. A liquid accumulating pool used for collecting the cooling mediums is arranged below the pair of rollers. The bottom of the liquid accumulating pool is connected with the circulation pool though a water returning pipeline. A medium flow guiding groove used for guiding the cooling mediums to the two sides is arranged below the rollers. An arc segment is arranged on the top of the medium flow guiding groove. Inclined segments are arranged at the two ends of the arc segment. The inclined segments incline outwards and downwards. Filters used for collecting surface scales of the strip in the cooling mediums and provided with filter screens are installed below the inclined segments. The ends of the inclined parts are matched with upper end openings of the filters.

Description

technical field [0001] The invention relates to a device for collecting oxide scales on the surface of copper and copper alloy strip hot-rolled lines, belonging to the technical field of metal processing and production. Background technique [0002] Hot rolling is the main production method of copper and copper alloy plate and strip. After the copper ingot is heated at high temperature, it is rolled at a large processing rate by the hot rolling mill. Since the strip is heated at high temperature, the surface of the strip will Oxide scale defects are formed. During the rolling process, the final rolling temperature is usually above 400 degrees, and secondary oxide scales will be produced. Due to elastic deformation, the secondary oxide scales on the surface of copper ingots are destroyed and fall off. After the iron oxide scales fall off, they fall into the pit of the main engine. The traditional method is to drain the water above when it naturally settles to a certain amount...

AI Technical Summary

Problems solved by technology

[0004] 1. Cooling water is used to cool the rolls in hot rolling production. Due to the large cooling capacity, the cooling water in hot rolling is recycled. Due to the recycled use, the cooled water is pumped back to the rolls, and the scale that falls off during rolling is polluted Cooling water, and there is a hidden danger of being pressed into the surface of the copper plate to be processed

[0005] 2. Increased the heavy physical labor of workers

[0006] 3. Since there is not enough cleaning space at the main machine of the hot rolling mill, it is difficult to carry out the cleaning work, and it is also difficult to clean it up, which increases the labor intensity of the hot rolling workers
