Abstract
The utility model discloses a kind of energy-saving type high temperature-resisting hearth roll, comprise roller, sleeve pipe, the roll shaft be fixedly connected in roller two stomidium; Sleeve pipe axially runs through roll shaft, roller cavity, and two ends are fixedly connected in roll shaft endoporus; Filling with insulation material in cavity between sleeve outer wall and roller cavity inner wall; Further improvement is: heat-barrier material is alumina silicate fibre; Roller outer wall is provided with resistance to high temperature oxidation wear-resistant coating.The utility model significantly reduces the heat transmission from roller to sleeve pipe, energy loss; High temperature resistant, anti-oxidant, wear-resisting.
Description
Technical field
The utility model relates to Equipment for Heating Processing, particularly relates to a kind of hearth roll.
Background technology
Hearth roll is located at for transmitting the steel bar plate of heat-treating in solution heat treatment furnace, and therefore hearth roll at high temperature works.Hearth roll comprises roller, the roll shaft be fixedly connected in roller two stomidium, produce a large amount of heats in the hearth roll course of work, have in these heats and be manyly delivered on roll shaft, cause roll shaft upper bearing (metal) temperature to raise, bearing, in severe condition of work, may cause bearing failure.For this reason, hearth roll is had to be provided with the sleeve pipe axially running through roll shaft, roller, cooling medium is passed through in sleeve pipe, to reduce the temperature on roll shaft, although this structure can reduce the heat taken away from roller inner chamber, but still have a large amount of heats to be delivered to sleeve pipe from roller inner chamber, taken away by the medium in sleeve pipe, cause the waste of energy.
Summary of the invention
The utility model, for the deficiencies in the prior art, proposes a kind ofly can significantly reduce by the thermal heat transfer capability of roller to sleeve pipe, significantly reduces the energy-saving type high temperature-resisting hearth roll of energy loss.
The utility model is achieved through the following technical solutions technical goal.
Energy-saving type high temperature-resisting hearth roll, comprises roller, sleeve pipe, the roll shaft be fixedly connected in roller two stomidium; Described sleeve pipe axially runs through roll shaft, roller cavity, and two ends are fixedly connected in roll shaft endoporus; Its improvements are: filling with insulation material in the cavity between described sleeve outer wall and roller cavity inner wall.
In said structure, described heat-barrier material is alumina silicate fibre.
In said structure, described roller outer wall is provided with resistance to high temperature oxidation wear-resistant coating.
In said structure, described resistance to high temperature oxidation wear-resistant coating is MCrAlY coating.
The utility model compared with prior art, has following good effect:
1. filling with insulation material in the cavity between sleeve outer wall and roller cavity inner wall, significantly reduces the heat transmission from roller to sleeve pipe, thus significantly reduces energy loss.
2. roller outer wall is provided with resistance to high temperature oxidation wear-resistant coating, can significantly improve resistance to high temperature oxidation of the present utility model, abrasion resistance properties.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below with reference to the accompanying drawings and the utility model is described in further detail in conjunction with the embodiments.
Energy-saving type high temperature-resisting hearth roll shown in the drawings, comprises roller 5, sleeve pipe 2, the roll shaft 1 be fixedly connected in roller 5 liang of stomidiums; Sleeve pipe 2 axially runs through roll shaft 1, roller 5 cavity, and two ends are fixedly connected in roll shaft 1 endoporus; Filling with insulation material 3 in cavity between sleeve pipe 2 outer wall and roller 5 cavity inner wall, in the present embodiment, heat-barrier material 3 is alumina silicate fibre.
Roller 5 outer wall is provided with resistance to high temperature oxidation wear-resistant coating 7, and in the present embodiment, resistance to high temperature oxidation wear-resistant coating 7 is MCrAlY coating.
