Abstract
The utility model relates to a high temperature accretion resistant anti-sticking furnace roller attached with a nanometer-coating. The high temperature accretion resistant anti-sticking furnace roller attached with the nanometer-coating comprises a furnace roller body. The furnace roller body comprises a furnace working plane arranged inside a heat treatment furnace and a furnace roller shaft portion arranged inside the heat treatment furnace. The working plane is provided with a nanometer protective layer. The high temperature accretion resistant anti-sticking furnace roller attached with the nanometer-coating has the advantages that a protective layer made of nanometer materials is arranged on the working plane of the heat treatment furnace roller and use cycle of the high temperature accretion resistance of the coating is above 12 moths and is much longer than the use cycle of the high temperature accretion resistance of the prior art so as to enable the furnace roller to continuously work for a long time, reduce production cost, and improve work efficiency. The defect of the prior art is overcome.
Description
Technical field
The utility model relates to a kind of heating furnace of Thick Plate Plant hot rolling line, particularly relates to a kind of high temperature resistance dross anti-adhesive with the furnace roller of nano coating.
Background technology
Stove is processed in the finishing of Thick Plate Plant hot rolling line, adopts furnace rolls to carry out the transmission of slab.Operating temperature in the heating furnace is about 500～1000 ℃, and furnace atmosphere is reproducibility, and is oxygen-free.But the existence of certain water vapour and air is arranged at the fire door place, and furnace roller is slush casting, and the surface is that coarse red bayberry is granular, and material is high temperature resistant chrome-bearing alloy steel, and rotating speed is 0.25～40 m/min.Find in the production process, there is dross phenomenon in various degree in the surface of furnace rolls, and particularly near 35 furnace rollers discharging opening more easily produce obvious buildup, and dross is the thickest to reach 5 millimeters.Research discovery, the generation of dross mainly are because in process of production, when the local adhesion of roll surface small pieces iron scale, superpose along with steel plate enters the accumulation of bringing iron scale in the stove into afterwards, and high-temperature oxydation occurs and progressively increase under the soft condition that is close to hot melt.Simultaneously, under the condition of high temperature, bonding stratiform iron scale and hearth roll stick and roll more closely projection.Moreover, furnace atmosphere also has considerable influence for the furnace roller dross, because combustion air passes in the radiant tube, when the radiant tube metal outer pipe is intact, its good sealing has guaranteed that combustion air can not enter in the burner hearth, however the radiant tube that under long term high temperature, burns, because Slurry pump, might crack, cause combustion air from crackle, to enter and cause oxidizing atmosphere in the burner hearth.Directly affect the normal operation of production line the service life of the heating furnace roller of this finishing production line, and the dross of furnace roller is also having a strong impact on product quality.
The utility model content
The utility model is exactly to overcome the existing problem of heating furnace in the prior art in order to address the above problem, the utility model provide a kind of high temperature resistance dross anti-adhesive with the furnace roller of nano coating to satisfy the demands.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of high temperature resistance dross anti-adhesive is with the furnace roller of nano coating; comprise the roll body body; described roll body body comprises cylindrical roll and is connected to two connecting axles at cylindrical roll 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 cylindrical roll.
Above-mentioned a kind of high temperature resistance dross anti-adhesive is characterized in that with the furnace roller of nano coating, and the outer surface length of described cylindrical roll is 5000mm-5500mm.
Above-mentioned a kind of high temperature resistance dross anti-adhesive is characterized in that with the furnace roller of nano coating, and the outer surface length of described cylindrical roll is 5200mm.
The beneficial effects of the utility model are: the layer protective layer that is made of nano material in the roll surface setting of heat-treatment furnace furnace roller; this coating high temperature resistance dross life cycle is more than 12 months; greatly be longer than the heat-treatment furnace furnace roller roll surface high temperature resistance dross cycle in the prior art; so that the long continuous firing of furnace roller; reduce production cost, improved operating efficiency.Improved the defective of prior art.

And the outer surface length of cylindrical roll 110 is 5000mm-5500mm, and in one of them optimum embodiment of the present utility model, the outer surface length of cylindrical roll 110 is 5200mm.
The layer protective layer that is consisted of by nano material in the roll surface setting of heat-treatment furnace furnace roller; this coating high temperature resistance dross life cycle is more than 12 months; greatly be longer than the heat-treatment furnace furnace roller roll surface high temperature resistance dross cycle in the prior art; so that the long continuous firing of furnace roller; 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.
Above demonstration 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.
