Description
Technical field
The utility model relates to the air-cooled furnace rollers in heating furnace technical field, especially heating furnace.
Background technique
Currently, water cooling furnace roller needs to cool down furnace roller using recirculated cooling water, and cooling water amount is in metallurgy industry
On the contrary the condition for maintaining water cooling furnace roller to work normally, water is big, the decline of furnace roller temperature, then rise, in guarantee furnace roller roller surface
Under the premise of temperature is no more than limiting temperature, then keep cooling water amount more fewer better, furnace body thermal loss can be reduced in this way, if
Water cooling furnace roller cooling effect is bad, then furnace roller roll surface just will appear dross, furnace roller deformation, or even not turn, and makes workpiece sideslip or card
Material eventually leads to product quality decline, if frequently replacement water cooling furnace roller, not only interrupts the production line of continuous operation, reduces
Product yield, and bottom roller of water-cooling furnace is generally formed by heat resisting steel centrifugal casting, and the cost of a large amount of heat resisting steel furnace roller spare parts is very
Height largely increases the operation cost of iron and steel enterprise.
Summary of the invention
The purpose of this utility model is to provide a kind of air-cooled furnace rollers of the big load-bearing of long span.
Realize the technical solution of the utility model aim are as follows: a kind of air-cooled furnace roller of big load-bearing of long span, including both ends
Roll shaft and be fixed on intermediate roll surface, the internal sleeve of the roll surface is equipped with load bearing roller, and the load bearing roller both ends are individually fixed in
The roll shaft at both ends, the load bearing roller outer surface are equipped with support rim, and the support rim is connected in the inner wall of roll surface, institute
It states and is equipped with heat dissipation plate on the roll shaft at both ends.
Preferably, cavity is equipped with inside the load bearing roller.
Preferably, heat-resistant insulation material is filled in the cavity inside the load bearing roller.
Preferably, the roll surface outer surface is equipped with stop collar.
Preferably, the support rim is equally distributed round ring boss.
Preferably, the heat dissipation plate is equipped with waveform radiating surface.
Preferably, the heat dissipation plate is made of aluminium.
Preferably, on the inner wall that the side of the roll shaft close to roll surface is inlaid in roll surface.
Compared with prior art, remarkable advantage: the utility model is equipped with the utility model using load bearing roller outer surface
Support rim effectively realizes the performance of the big load-bearing of furnace roller long span, in Large Furnace, effectively prevents furnace roller and works long hours
Intensity decline, bending deformation afterwards；Waveform radiating surface, Ke Yiyou are equipped with using heat dissipation plate and heat dissipation plate is equipped on roll shaft
The heat dissipation effect that natural cooling is strengthened on effect ground not only avoids water-cooling without to pass through water-cooling inside furnace roller
Scale problems, and more economical environmental protection, furnace roller are realized non-maintaining；It is equipped with cavity inside load bearing roller, is filled with heat-resisting guarantor in cavity
Adiabator mitigates furnace roller weight and is also conducive to save manufacturing cost simultaneously.
The utility model is described in further detail with reference to the accompanying drawing.

5 outer surface of load bearing roller is equipped with support rim 8, and the support rim 8 is connected in the inner wall of roll surface 3, the support
Boss 8 is equally distributed round ring boss, and heat dissipation plate 7 is equipped on the roll shaft 1 at the both ends, and the heat dissipation plate 7 is equipped with wave
Shape wave radiating surface 9, the heat dissipation plate 7 are made of aluminium, cavity 6 are equipped with inside the load bearing roller 5, inside the load bearing roller 5
It is filled with heat-resistant insulation material in cavity 6, the 3 outer surface both ends of roll surface are all provided with restraining position ring block 4, and the roll shaft 1 is close to roll surface 3
Side be inlaid on the inner wall of roll surface 3.
The utility model is equipped with support rim 8 using 5 outer surface of load bearing roller, effectively realizes the big load-bearing of furnace roller long span
Performance, in Large Furnace, effectively prevent the intensity after furnace roller works long hours decline, bending deformation；Using equal on roll shaft 1
It is equipped with waveform radiating surface 9 equipped with heat dissipation plate 7 and heat dissipation plate 7, can effectively strengthen the heat dissipation effect of natural cooling, and nothing
It needs to not only avoid water-cooling scale problems, and more economical environmental protection, furnace roller are real by water-cooling inside furnace roller
It is existing non-maintaining；It is equipped with cavity 6 inside load bearing roller 5, heat-resistant insulation material is filled in cavity 6, mitigates furnace roller weight and is also conducive to simultaneously
Save manufacturing cost.
