Problems solved by technology

However, the sinking roller of the prior art also has certain defects: since the spiral groove is a spiral groove of equal depth and equal pitch, the flow velocity of the aluminum-zinc-iron alloy element is basically the same when flowing in the spiral groove, and the resistance is greater when it flows toward both sides. Causes poor flow, a small part forms nodules on the surface of the roller, affects product quality, increases labor intensity, and causes waste of resources

Embodiment Construction

[0012] The hot-dip galvanized steel strip sinking roll includes a cylindrical roll body 1 and a roll shaft 2; with the axially symmetrical centerline of the roll body 1 as the dividing line, the surface of the roller body 1 on both sides of the dividing line is provided with spiral grooves in opposite directions 1.1; the bottom of the spiral groove 1.1 is V-shaped; the depth of the V-shaped spiral groove 1.1 from the boundary line to both sides becomes larger and larger.

[0013] The pitch of each spiral groove 1.1 becomes larger and larger from the boundary line to both sides, and 2 to 3 spiral grooves 1.1 are evenly arranged on the surface of the roller body 1 on both sides of the boundary line. In this embodiment, the roller bodies on both sides of the boundary line 1. Two spiral grooves 1.1 are uniformly provided on each surface.

Abstract

The invention discloses a hot galvanizing steel belt sinking roller. The hot galvanizing steel belt sinking roller comprises a cylindrical roller body and a roller shaft. The axial symmetrical centralline of the roller body serves as a boundary. Spiral grooves in opposite rotating directions are formed in the positions, at two sides of the boundary, of the surface of the roller body. The bottomsof the spiral grooves are in the V shape. The depth of each V-shaped groove is greater and greater from the boundary. The hot galvanizing steel belt sinking roller is further characterized that the screw pitch of each spiral groove is greater and greater from the boundary to two sides of each spiral groove; 2 to 3 spiral grooves are formed in each surface of the roller on the two sides of the boundary. According to the hot galvanizing steel belt sinking roller, by means of changing the depths and the screw pitches of the spiral grooves, aluminum zinc iron alloy element can flow smoothly, so that the problem that nodulations are formed on the surface of the roller is thoroughly solved.

Description

technical field [0001] The invention relates to a sinking roll on a hot-dip galvanizing line. Background technique [0002] The sinking roll is one of the important equipment on the hot-dip galvanizing line. It is made of stainless steel. During production, the sinking roll needs to be immersed in the molten zinc liquid and rotate with the drag of the galvanized sheet. During the galvanizing process, aluminum, iron, and zinc alloy elements will adhere to the roll surface, forming uneven nodules, that is, sticky slag; When the zinc liquid comes into contact with the roller, zinc-iron alloy is also produced to adhere to the surface of the roller. The above-mentioned phenomenon becomes more and more serious with the passage of time, causing the strip steel to produce arches and protrusions, thereby seriously affecting the product quality of the galvanized sheet. In this case, the slag-sticking sinker rolls have to be replaced frequently, which affects production, increases la...
