Abstract
Wiper blade new structure on hot-rolling line, comprise upper Wiper blade, several backplates, several backplates are rabbeted together side by side, each backplate are all welded with two anchoring screws, and Wiper blade is tightened together with several backplates by anchoring screw and round nut.The utility model structure is reliable rationally, water sealing effect is good, ensure that steel rolling surface quality and various performance requirement, significantly extends service life, decrease maintenance cost, reduce the labour intensity of workman.
Description
Technical field
The utility model relates to steel rolling equipment technical field, particularly relates to Wiper blade new structure on a kind of ESP hot-rolling line.
Background technology
Wiper blade is used in ESP hot-rolling line exit, heat source temperature is 800-1000 ° of C, heat distance is 30-100cm only, the safe handling of roll depends on the cooling of cooling water, in order to namely guarantee roll effective cooling, belt steel rolling temperature can be ensured again simultaneously, therefore needing roll to have good Wiper blade to fit in roller surface, making cooling water fully cool roll does not make again cooling water drop on the steel plate of high temperature rolling, guarantees Surfaces of Hot Rolled Strip and various performance requirement.Present domestic hot rolling technology technical development is very fast, and hot rolled plate thickness is to thinner future development, and the time of continuous rolling lengthens, and this is higher to the performance requirement of Wiper blade.And the Wiper blade used at present has two kinds, one uses bakelite or nylon Wiper blade, and weight is at about 30kg, and due to lighter in weight, so safer, unique problem is that wearing and tearing are very fast, changes use cost relatively high.Another kind makes cast iron Wiper blade, every block weight is at 150kg, each replacing needs 4 people lift in frame together and are fixed installation, install replacing construction and labour intensity larger, and metal Wiper blade easy damaged work roll surface, cast iron Wiper blade affects steel rolling quality, there is safety hazards, about generally also can only use fortnight.In order to weight reduction, do not damage work roll surface, although indivedual producer can use install wool felt additional to reach a grade water effect, the degree of wear is more slow than bakelite Wiper blade, and this spare parts cost can be higher; Especially go up Wiper blade water quench, easily have influence on the performance of belt steel surface weight and band steel interior tissue.How improvement is carried out to upper Wiper blade and become those skilled in the art's urgent problem.
Summary of the invention
The purpose of this utility model is to provide Wiper blade new structure on a kind of hot-rolling line, this structure is reliable rationally, water sealing effect is good, ensure that steel rolling surface quality and various performance requirement, can significantly increase the service life, reduce maintenance cost, reduce the labour intensity of workman.
The utility model is achieved in that Wiper blade new structure on hot-rolling line, it is characterized in that: comprise upper Wiper blade, several backplates, several backplates are rabbeted together side by side, each backplate is all welded with two anchoring screws, Wiper blade is tightened together with several backplates by anchoring screw and round nut.
Described round nut is embedded in upper Wiper blade.
Expansion gap is provided with between described backplate and backplate.
Described upper Wiper blade head is provided with an inclined-plane, inclined-plane and bottom surface are provided with angle α, and described bottom surface head is provided with the first chamfering, is provided with angle β between the first chamfering and inclined-plane, first chamfering head is provided with the second chamfering, is provided with angle γ between the second chamfering and inclined-plane.
Described angle γ is greater than angle β, and angle β is greater than angle α; Described angle γ is set to acute angle.
Described upper Wiper blade employing material is: high molecular polymer.
The utility model structure is reliable rationally, water sealing effect is good, ensure that steel rolling surface quality and various performance requirement, significantly extends service life, decrease maintenance cost, reduce the labour intensity of workman.

In figure 1, backplate, 2, anchoring screw, 3, upper Wiper blade, the 4, first chamfering, the 5, second chamfering, 6, angle γ, 7, angle β, 8, angle α, 9, round nut.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described:
With reference to accompanying drawing, Wiper blade new structure on hot-rolling line, it is characterized in that: comprise upper Wiper blade 3, several backplates 1, several backplates 1 are rabbeted together side by side, each backplate 1 is all welded with two anchoring screws 2, Wiper blade 3 is tightened together with several backplates 1 by anchoring screw 2 and round nut 7.Described round nut 7 is embedded in upper Wiper blade 3.Expansion gap is provided with between described backplate 1 and backplate 1.Described upper Wiper blade 3 head is provided with an inclined-plane, inclined-plane and bottom surface are provided with angle α 8, and described bottom surface head is provided with the first chamfering, is provided with angle β 7 between the first chamfering and inclined-plane, first chamfering head is provided with the second chamfering, is provided with angle γ 6 between the second chamfering and inclined-plane.Described angle γ 6 is greater than angle β 7, and angle β 7 is greater than angle α; Described angle γ 6 is set to acute angle.Described upper Wiper blade 3 adopts material to be: high molecular polymer.
During concrete enforcement, in order to meet the overlength technique for continuous rolling of ESP hot-rolling line, and the requirement of Wiper blade Long-Time Service on high molecular polymer, devise the composite construction of Wiper blade and several backplates, this composite construction can make full use of the resistance to extreme temperature of high molecular polymer, backplate to a great extent heat to having reflected away, reduce photothermal gathering, effectively control the hot face temperature of Wiper blade lower than 500 ° of C, the work that in guarantee, Wiper blade can be steady in a long-term.Upper Wiper blade head is provided with the second chamfering and the first chamfering can increase the service life.The utility model installation site can adjust according to actual conditions, novel high polymer Wiper blade is used in ESP hot-rolling line exit, be used in and reach more than 40 days service time on ESP hot-rolling line, be used in and reach 4 ~ 5 months service time on conventional mill, and breaker roll working face is without any damage, the upper Wiper blade heat resistance made with high molecular polymer and anti-wear performance good, good with rolling face cohesive, effectively improve water sealing effect, No leakage, Non-carbonized phenomenon, ensure that steel rolling surface quality and various performance requirement, significantly extend service life.
