Abstract
The utility model discloses a novel hearth roll includes and is columniform hearth roll body, the hearth roll body includes the dabber, the inside cover of dabber is equipped with the back shaft, the surface of dabber is equipped with the asbestos layer, the last cladding of asbestos layer has carbon cooking vessel layer, the tip on carbon cooking vessel layer still is equipped with clears away the ring, clear away the ring can along carbon cooking vessel layer sliding surface, reduce the heat that the dabber received through the asbestos layer, prolonged the life of dabber, utilize the high temperature oxidation resistance performance on carbon cooking vessel layer to avoid the hearth roll surface to form the caking to steel product's quality has been guaranteed.
Description
Technical field
The utility model is related to steel rolling equipment field, and in particular to new hearth roll.
Background technology
In steel rolling process at this stage, hearth roll in use easily there arises a problem that：
1. easily formed in furnace bottom roller surface and lumpd, cause product made from steel surface damage；
2. mandrel is easily influenceed by high temperature during use, reduces the service life of hearth roll.
Utility model content
In order to solve the above technical problems, the utility model proposes new hearth roll, ensureing product quality and prolonging to reach
The purpose of hearth roll service life long.
To reach above-mentioned purpose, the technical solution of the utility model is as follows：
A kind of new hearth roll, includes the furnace bottom roller body in cylinder, and the furnace bottom roller body includes mandrel, institute
State and support shaft is arranged with inside mandrel, the outer surface of the mandrel is provided with asbestos layer, and carbon cooking vessel is coated with the asbestos layer
Layer, the end of the carbon cooking vessel layer is additionally provided with removing annulus, and the removing annulus can be slided along the carbon cooking vessel layer surface.
The heat that the utility model is subject to by asbestos layer reduction mandrel, extends the service life of mandrel；Made pottery using carbon
The high-temperature oxidation resistance of interlayer avoids the furnace bottom roller surface from forming caking, and further avoids hearth roll table using annulus is removed
There is caking in face, so as to ensure that the quality of product made from steel.
Used as preferred, the asbestos layer is fixed using interference fit and is wrapped on the mandrel.
Used as preferred, the carbon cooking vessel layer is set on the asbestos layer by the way of interference fit.
The utility model has the following advantages that：
The heat that the utility model is subject to by asbestos layer reduction mandrel, extends the service life of mandrel；Made pottery using carbon
The high-temperature oxidation resistance of interlayer avoids the furnace bottom roller surface from forming caking, and further avoids hearth roll table using annulus is removed
There is caking in face, so as to ensure that the quality of product made from steel.
Brief description of the drawings
In order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing to be used needed for description of the prior art is briefly described.
Fig. 1 is the schematic side view of new hearth roll disclosed in the utility model embodiment.
Numeral and the corresponding component title represented by letter in figure：
1. the carbon cooking vessel of 2. support shaft of mandrel, 3. asbestos layer 4. layer 5. removes annulus.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe.
The utility model provides new hearth roll, and its operation principle is the heat being subject to by asbestos layer reduction mandrel,
Extend the service life of mandrel；Furnace bottom roller surface is avoided to form caking using the high-temperature oxidation resistance of carbon cooking vessel layer, and
Furnace bottom roller surface is further avoided caking occur using annulus is removed, so as to ensure that the quality of product made from steel.
The utility model is described in further detail with reference to embodiment and specific embodiment.
A kind of new hearth roll as shown in Figure 1, includes the furnace bottom roller body in cylinder, and the furnace bottom roller body is included
Have mandrel 1, be arranged with support shaft 2 inside the mandrel, the outer surface of the mandrel is provided with asbestos layer 3, the asbestos layer it is upper
Carbon cooking vessel layer 4 is coated with, the end of the carbon cooking vessel layer is additionally provided with removing annulus 5, and the removing annulus can make pottery along the carbon
Slide on interlayer surface.
The heat that the utility model is subject to by asbestos layer reduction mandrel, extends the service life of mandrel；Made pottery using carbon
The high-temperature oxidation resistance of interlayer come avoid furnace bottom roller surface formed caking, so as to ensure that the quality of product made from steel.Also by carbon
Cooking vessel layer avoids the pressure that mandrel and support shaft are subject to, and further extends the service life of equipment.
Used as preferred, the asbestos layer is fixed using interference fit and is wrapped on the mandrel.
Used as preferred, the carbon cooking vessel layer is set on the asbestos layer by the way of interference fit.
By way of more than, new hearth roll provided by the utility model is subject to by asbestos layer reduction mandrel
Heat, extends the service life of mandrel；Furnace bottom roller surface is avoided to form knot using the high-temperature oxidation resistance of carbon cooking vessel layer
Block, and further avoid furnace bottom roller surface from caking occur using annulus is removed, so as to ensure that the quality of product made from steel.
Above-described is only the preferred embodiment of new hearth roll disclosed in the utility model, it is noted that right
For one of ordinary skill in the art, on the premise of the utility model creation design is not departed from, can also make some
Deformation and improvement, these belong to protection domain of the present utility model.
