Anti-nodulation sink roll

Abstract

The invention discloses an anti-nodulation sink roll, and relates to the technical field of sink roll equipment. The anti-nodulation sink roll comprises a sink roll body, connecting shafts are fixedlyconnected to the left end and the right end of the sink roll body, rotating shafts are fixedly connected to the ends, away from each other, of the two connecting shafts, the circumferential surfacesof the two rotating shafts are sleeved with fixing rings, the surfaces of the two fixing rings are each fixedly connected with two triangular bent rods, and screw rods are fixedly connected to the other ends of the four triangular bent rods. The two screw rods located on the front portion and the two screw rods located on the rear portion are in threaded connection with two-way threaded sleeves, and the circumferential surfaces of the two two-way threaded sleeves are sleeved with sliding pipes. When the position of the sink roll is fixed, a first scraper slides on the circumferential surface of the sink roll, and the fixing rings are rotated, so that nodules on the surface of the sink roll are scraped off. When the positions of the triangular bent rods are fixed, relative movement of a second scraper and the sink roll is achieved by rotating the sink roll, and nodules on the surface of the sink roll are scraped off.

Description

technical field [0001] The invention belongs to the technical field of sinking roll equipment, in particular to an anti-nodulation sinking roll. Background technique [0002] The sinking roller is one of the important equipment on the hot-dip galvanizing line. During the production process of the hot-dip galvanizing line, it is corroded by the zinc liquid and under the action of strip tension, it is subjected to a large friction force, so it is easy to sink The sliding part of the roller journal is worn and damaged; during the production of the sinking roller, the sinking roller needs to be immersed in the molten zinc liquid as a whole, and rotate with the drag of the galvanized sheet. In the hot-dip galvanizing production line, the zinc liquid will sink The roller is highly corrosive. The sinking roller is used in the zinc pot of the galvanizing line, and the working temperature reaches 600-700°C. During production, it is necessary to immerse the sinking roller in the molte...
