Abstract

The utility model discloses a straight flute improved generation sink roll, including the roll body, being set up the choke plug axle in the roll body both ends respectively, even interval is setting up the slot on the axial roll surface of roll body, and the slot width is 3mm, the slot degree of depth is 1.5-2.5 mm, and interval between the adjacent slot is 30mm, and the plane at slot place all is mutually perpendicular with the roll body axis, the epaxial outer peripheral face of choke plug on even interval set up 6U-shaped through-holes. The utility model discloses can reduce sink roll not smooth and the steel band fish tail that arouses and sink roll slot arouse the emergence volume of roll mark defect.

Description

Straight flute improved sink roll

Technical Field

The utility model relates to a straight flute improved generation sink roll.

Background

The sink roll system is the main process equipment of the hot galvanizing unit, the sink roll system design, installation and operation technology is the key technology of the hot galvanizing unit, under the normal production condition, the sink roll generates friction force between the strip steel and the sink roll under the action of gravity G, buoyancy F and positive pressure N, friction force F, pulling force T1 and T2 given by a support arm bearing bush, so that the roll runs continuously, and zinc liquid between the strip steel and the roll is discharged timely due to the reasonable design of a sink roll groove, otherwise, if the zinc liquid is clamped in the middle, the strip steel slips on the roll surface, so that the scratch of the strip steel and the roll mark defect of thick strip production are caused, and the smooth production line and the product quality are influenced.

Disclosure of Invention

An object of the utility model is to provide a straight flute improved generation sink roll can reduce sink roll operation not smooth and the steel band fish tail that arouses and sink roll slot arouse the emergence volume of roll mark defect.

The utility model aims at realizing like this, a straight flute improved generation sink roll, including the roll body, being set up the end cap axle in the roll body both ends respectively, even interval is setting up the slot on the axial roll surface of roll body, and the slot width is 3mm, the slot degree of depth is 1.5-2.5 mm, and the interval between the adjacent slot is 30mm, and the plane at slot place all is mutually perpendicular with the roll body axis, the epaxial peripheral face of end cap on even interval set up 6U-shaped through-holes.

The utility model discloses an improve the structure of sink roll, increase the frictional force of belted steel and sink roll, make the operation that the roller does not stop, in time get rid of the zinc liquid between belted steel and the roller, still consider the sink roll system simultaneously and make full use of as much as possible, need to redesign and optimize the distribution, the shape of the slot of sink roll face, through the production practice shows, improved the running situation of sink roll after using straight flute improved generation new sink roll, reduced the emergence of the roll mark defect that causes because of the steel band fish tail that sink roll operation is not smooth and sink roll slot; the purposes of low investment and improved quality are achieved.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings.

Fig. 1 is a schematic view of the structure of the present invention;

fig. 2 is a schematic side view of the present invention.

Detailed Description

The utility model provides a straight flute improved generation sink roll, as shown in fig. 1, fig. 2, draw together roll body 1, is setting up end cap axle 5 in the 1 both ends of roll body respectively, and even interval is setting up slot 2 on the axial roll surface of roll body 1, and the slot 2 width is 3mm, and the 2 degree of depth of slot is 1.5-2.5 mm, and the interval between adjacent slot 2 is 30mm, and the plane at slot place all is mutually perpendicular with the roll body axis, 5 outer peripheral face 3 of end cap axle on even interval set up 6U-shaped through-holes 4.

Claims (1)

1. The utility model provides a straight flute improved generation sink roll, includes the roll body, is setting up choke plug axle, characterized by in the roll body both ends respectively: the axial roll surface of the roll body is uniformly provided with grooves at intervals, the width of each groove is 3mm, the depth of each groove is 1.5-2.5 mm, the distance between every two adjacent grooves is 30mm, the plane where the grooves are located is perpendicular to the axis of the roll body, and the outer peripheral surface of the plug shaft is uniformly provided with 6U-shaped through holes at intervals.
