Abstract
The utility model relates to a high-performance wearproof hot rolling leveling roll with a nanometer coating. The high-performance wearproof hot rolling leveling roll with the nanometer coating comprises a leveling roll body which comprises a leveling roll effective working surface and a leveling roll shaft part, wherein the leveling roll effective working surface of the leveling roll is provided with a layer of a nanometer protection coating. The high-performance wearproof hot rolling leveling roll with the nanometer coating has the advantages that the protection coating made of nanometer materials is arranged on the leveling roll effective working surface of the hot rolling leveling machine; use period of resistance to alternating thermal stress and roll surface cracks of the protection coating is improved four to six times that of an original protection coating; use period of the leveling roll effective working surface is much longer than a leveling roll working surface in the prior art; and therefore a leveling roll can continuously work for a long time, production cost is reduced, work efficiency is improved, and shortcoming of the prior art are overcome.
Description
Technical field
The utility model relates to a kind of planisher, particularly relates to a kind of high-performance abrasion-proof damage with the hot-rolled leveling roller of nano coating.
Background technology
Strip flatness is that plate shape is with the important quality index of steel.Along with industrial expansion, more and more stricter to the strip shape quality requirement of Strip, present common way is to improve plate shape in finishing by smooth operation.Leveling roll is the extreme trace operation of control and improvement hot-rolled product, is directly connected to product quality, so also corresponding very high to the roll surface quality requirement of leveling roll.Now be subjected to the restriction of life cycle, the use cost of leveling roll is high, and production efficiency is low, so lifting roller surface hardening technology, prolonging life cycle, reducing use cost, enhance productivity is the emphasis that advances and study at present.
The service load of hot rolling and leveling machine leveling roll is respectively 1200,1700,1360 tons (2050,1880,1580 zones), impulsive contact force is 200kg to the maximum in the work, because all very large with bump and the frictional force of steel plate, so the destructions such as wearing and tearing, pit and dry slag often appear in leveling roll.Again because very high to the quality requirement of steel plate, roll surface quality requirement to leveling roll is also corresponding very high, as the roll surface roughness by the zone different 0.2-0.4,0.8,1.0-2.0(2050,1880,1580 zones of will reaching respectively with frame) etc., wearing and tearing are not less than 0.3mm, the average roll change cycle be respectively 600 tons, 2000 tons, 3000 tons (1580,1880,2050 zones) so the roll change frequency of leveling roll very high.And if surface of steel plate cut occurs, takes off piece or plucking in producing, and will shut down roll change, had a strong impact on carrying out smoothly of producing.
The utility model content
The utility model is exactly to overcome the existing problem of planisher in the prior art in order to address the above problem, and the utility model provides a kind of high-performance abrasion-proof to decrease hot-rolled leveling roller with nano coating to satisfy the demands.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of high-performance abrasion-proof decreases the hot-rolled leveling roller with nano coating, comprises roll body and the axis body that is connected to roll body both ends of the surface center, it is characterized in that, is provided with one deck nanometer protective layer on the outer surface of described roll body.
Above-mentioned a kind of high-performance abrasion-proof decreases the hot-rolled leveling roller with nano coating, it is characterized in that the outer surface length of described roll body is 1300mm-1800mm.
Above-mentioned a kind of high-performance abrasion-proof decreases the hot-rolled leveling roller with nano coating, it is characterized in that the outer surface length of described roll body is 1580mm.
The beneficial effects of the utility model are: the layer protective layer that is made of nano material in the setting of planisher leveling roll working face; the wear-resistant life cycle of the anti-roll surface crackle of this coating alternating thermal stress resisting is increased to 4 ~ 6 times; greatly be longer than the service life of planisher leveling roll working face in the prior art; so that the long continuous firing of leveling roll; reduce production cost, improved operating efficiency.Improved the defective of prior art.

And the outer surface length of roll body 100 is 1300mm-1800mm, and in one of them optimum embodiment of the present utility model, the outer surface length of roll body 100 is 1580mm.
The layer protective layer that is consisted of by nano material in the setting of planisher leveling roll working face; the wear-resistant life cycle of the anti-roll surface crackle of this coating alternating thermal stress resisting is increased to 4 ~ 6 times; greatly be longer than the service life of planisher leveling roll working face in the prior art; so that the long continuous firing of leveling roll; reduce production cost, improved operating efficiency.Improved the defective of prior art.
The nanometer protective layer generally adopts plasma spraying; control by process conditions reaches the high-bond with base material, and the process conditions of spraying comprise hydrogen and argon flow amount, spray distance, spray angle, for powder rate and the flow of carrier gas, the power of electric arc, the adjusting control of current/voltage, the flow of plasma water and the control of substrate temperature.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
