Abstract
The utility model relates to a metallurgical machinery, concretely relates to back-up roll that keeps super wide checkered plate limit portion flower beans integrality of slab band rolling mill. The technical scheme of the utility model as follows: a supporting roller for keeping the integrity of flower beans at the edge part of an ultra-wide checkered plate of a plate and strip rolling mill is characterized in that the edge chamfer of a roller body of the supporting roller is a composite curve and comprises a first section of arc and a second section of arc; the radius of the first section of arc is 25000 and 30000mm, and the distance between the center of the first section of arc and the edge of the roller body is 275 mm; the radius of the second section of arc is 3500 plus 4500mm, and the distance between the center of the second section of arc and the edge of the roller body is 150 mm; the first section of circular arc is tangent to the outer diameter of the roller body, and the second section of circular arc and the first section of circular arc are intersected and smoothly transited at a position 150mm away from the edge of the roller body. The utility model provides a damaged of checkered plate roller flower bean and lead to the checkered plate product to degrade or judge useless problem when super wide checkered plate produces, improved the lumber recovery, reduced the product defect rate, prolonged the life of checkered roller simultaneously.
Description
Technical Field
The utility model relates to a metallurgical machinery, concretely relates to back-up roll that keeps super wide checkered plate limit portion flower beans integrality of slab band rolling mill.
Background
The checkered plate has the advantages of attractive appearance, skid resistance, reinforced performance and the like, and is widely applied to the fields of traffic, buildings, decoration, machinery, shipbuilding and the like. The mechanical property and mechanical property requirements of the checkered plate are not high, and the quality of the checkered plate is mainly reflected in the rate of pattern formation and the height of the patterns. The width is 1250 mm or 1500 mm. With the increasing demand of users, the ultra-wide checkered plate with the thickness of 1800 plus 2150mm has attracted attention. When the strip rolling mill produces the 1800 plus-plate pattern plate with the width of 2150mm, contact stress in a harmful contact area of a support roller of the strip rolling mill and the pattern roller is unbalanced, so that the edge part of the pattern roller is damaged, the pattern plate is unattractive, users cannot accept the pattern plate, products are degraded or subjected to waste judgment, production cost is high, and the yield is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model provides a back-up roll that keeps board strip rolling mill super wide checkered plate limit portion flower beans integrality has solved super wide checkered plate production time checkered plate flower beans damaged and lead to checkered plate product to degrade or judge useless problem, has improved the lumber recovery, has reduced the product defect rate, has prolonged the life of checkered roller simultaneously.
The technical scheme of the utility model as follows: a supporting roller for keeping the integrity of flower beans at the edge part of an ultra-wide checkered plate of a plate and strip rolling mill is characterized in that the edge chamfer of a roller body of the supporting roller is a composite curve and comprises a first section of arc and a second section of arc; the radius of the first section of arc is 25000 and 30000mm, and the distance between the center of the first section of arc and the edge of the roller body is 275 mm; the radius of the second section of arc is 3500 plus 4500mm, and the distance between the center of the second section of arc and the edge of the roller body is 150 mm; the first section of circular arc is tangent to the outer diameter of the roller body, and the second section of circular arc and the first section of circular arc are intersected and smoothly transited at a position 150mm away from the edge of the roller body.
The utility model has the advantages that: the utility model sets the radius of the arc curve and the arc length according to the flower bean damage position of the pattern roller, and better solves the problem that the pattern plate product is degraded or judged to be waste due to the damage of the flower bean of the pattern roller caused by the unbalanced stress distribution between the pattern roller and the supporting roller when the ultra-wide pattern plate is produced; the product defect rate is reduced, and the comprehensive benefits of enterprises are improved.
Drawings
FIG. 1 is a schematic view of the positions of a support roll, a pattern roll and a strip steel in production;
FIG. 2 is a schematic view of a support roll configuration;
fig. 3 is a side chamfer structure view of the roll body of the support roll.
Detailed Description
As shown in figure 1, in production, two supporting rollers 1 respectively press two pattern rollers 2, the two pattern rollers 2 process strip steel 3, and a contact area between the edge of the roller body of the supporting roller 1 and the pattern roller 2 is a harmful contact area 4.
As shown in fig. 2 and 3, an edge chamfer 5 of a roller body 6 of a support roller 1 is a composite curve and comprises a first section of circular arc 5-1 and a second section of circular arc 5-2; the radius of the first section of circular arc 5-1 is 25000 and 30000mm, and the distance from the center of the first section of circular arc 5-1 to the edge 7 of the roller body is 275 mm; the radius of the second section of arc 5-2 is 3500 plus 4500mm, and the distance from the center of the second section of arc 5-2 to the edge 7 of the roller body is 150 mm; the first section of circular arc 5-1 is tangent to the outer diameter 8 of the roller body, and the second section of circular arc 5-2 and the first section of circular arc 5-1 are intersected and smoothly transited at the position 7 of the roller body and 150mm away from the edge.
In the supporting roller 1, the edge chamfer 5 of the roller body 6 is a composite curve, and hard contact with the contact area of the patterned roller 2 is avoided, so that the damage of the edge patterned bean of the patterned roller 2 is reduced; and simultaneously, the supporting roller 1 can ensure the balanced pressure application of the patterned roller 2.
