Abstract
The invention discloses an energy-saving type high temperature resistant hearth roll, which includes a roller, a casing, and roll shafts fixedly connected in two end holes of the roller. The casing runs through the roll shafts and the roller cavity axially, and the two ends are fixedly connected in the inner holes of the roll shafts; the cavity between the casing outer wall and the roller cavity is filled with a thermal insulation material. The further improvement lies in that: the thermal insulation material is aluminum silicate fiber. The outer wall of the roller is provided with a high temperature oxidation resistant and wearproof coating. The energy-saving type high temperature resistant hearth roll provided by the invention significantly reduces heat transfer from the roller to the casing and energy loss, and has the advantages of high temperature resistance, oxidation resistance, and wear resistance.
Description
Technical field
The present invention relates to Equipment for Heating Processing, particularly relate to a kind of hearth roll.
Background technology
Hearth roll is located in solution heat treatment furnace and is carried out heat treated steel bar plate for transmission, and therefore hearth roll at high temperature works.The roll shaft that hearth roll includes roller, is fixedly connected in roller two stomidium, hearth roll work process produces substantial amounts of heat, these heats has and many is delivered on roll shaft, cause roll shaft upper bearing (metal) temperature to raise, bearing is in severe working condition, it is possible to can cause bearing failure.For this, hearth roll is had to be provided with the sleeve pipe axially penetrating through roll shaft, roller, sleeve pipe passes through cooling medium, to reduce the temperature on roll shaft, although this structure can reduce the heat taken away from roller inner chamber, but still have substantial amounts of heat to be delivered to sleeve pipe from roller inner chamber, the medium in sleeve pipe take away, cause the waste of energy.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is proposed to a kind of can significantly reduce by roller to the thermal heat transfer capability of sleeve pipe, substantially reduce the energy-saving type high temperature-resisting hearth roll of energy loss.
The present invention is achieved through the following technical solutions technical goal.
Energy-saving type high temperature-resisting hearth roll, including roller, sleeve pipe, the roll shaft that is fixedly connected in roller two stomidium；Described sleeve pipe axially penetrates through roll shaft, roller cavity, and two ends are fixedly connected in roll shaft endoporus；It thes improvement is that: 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 present invention compared with prior art, has the positive effect that:
1. filling with insulation material in the cavity between sleeve outer wall and roller cavity inner wall, substantially reduces and transmits to the heat of sleeve pipe from roller, thus substantially reducing energy loss.
2. roller outer wall is provided with resistance to high temperature oxidation wear-resistant coating, is remarkably improved the resistance to high temperature oxidation of the present invention, abrasion resistance properties.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
Below according to accompanying drawing and the invention will be further described in conjunction with the embodiments.
Energy-saving type high temperature-resisting hearth roll shown in the drawings, including roller 5, sleeve pipe 2, the roll shaft 1 that is fixedly connected in 5 liang of stomidiums of roller；Sleeve pipe 2 axially penetrates 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.
