Abstract
The utility model discloses a kind of resistant to elevated temperatures roller structure of effectively insulating, including a roll shaft；Both ends are respectively provided with a heat-resisting rib on the roll shaft, and the evenly spaced collars of a row is additionally provided between the heat-resisting rib in both sides, and described collars is similarly installed on roll shaft, and fire resisting pouring material is filled between adjacent collars and between collars and heat-resisting rib.Do not have the expensive heat-resisting steel material of integral installation between the heat-resisting rib of the utility model, but it is mounted with the collars of evenly spaced sheet, fire resisting pouring material is filled between collars, fire resisting pouring material is staggered with collars, the thickness of collars is only arranged to 1 10mm, the roll surface overwhelming majority being so in contact in conveying with high temperature billet steel is fire resisting pouring material, reduces the heat that high temperature billet steel is transferred to roll shaft by collars, so that roller reaches heat-insulated resistant to elevated temperatures purpose.
Description
Technical field
It the utility model is related to a kind of roller-way conveying equipment, specifically a kind of resistant to elevated temperatures roller structure of effectively insulating.
Background technology
Current existing high temperature resistant roller structure, the body of roll uses monoblock cast mostly, then rear welding processing is mutually worn with roll shaft,
Whole roller is using expensive heat-resisting steel material, to adapt to the conveying operation of high temperature billet steel；But existing high temperature resistant roller,
Because its body of roll is all heat resisting steel, heat-conducting area is big, and big heat be present toward contact when conveying high temperature billet steel passes through body of roll transmission
To roll shaft, so as to cause roll temperatures too high, and then the bearing of roller and its correlation, the service life of seal are reduced；And hold high
Expensive heat-resisting steel material also make it that the cost of manufacture of roller is higher, is unfavorable for a wide range of industrial application.
Utility model content
The purpose of this utility model is led in view of the deficienciess of the prior art, providing a kind of high temperature billet steel that can both reduce
Cross the resistant to elevated temperatures roller structure of effectively insulating that collars is transferred to the heat and can reduction roller manufacturing cost of roll shaft, its technical side
Case is as follows：
A kind of resistant to elevated temperatures roller structure of effectively insulating, including a roll shaft；It is heat-resisting to be respectively provided with one for both ends on the roll shaft
Rib, and the evenly spaced collars of a row is additionally provided between the heat-resisting rib in both sides, described collars is similarly installed on roll shaft,
And fire resisting pouring material is filled between adjacent collars and between collars and heat-resisting rib；The external diameter of described collars is less than resistance to
Hot rib top external diameter, and fire resisting pouring material pour height and the external diameter of collars mutually maintains an equal level.
Preferably, the one end of described roll shaft is additionally provided with swivel joint；And the inside of roll shaft is additionally provided with and revolved
The water-cooling channel that adapter is connected.
Preferably, described collars is laminated structure, and the thickness of collars is arranged to 1-10mm.
Preferably, described collars is altogether at least provided with three, and fire resisting pouring material then relative set；Described collars
Quantity can be according to the corresponding setting of actual conditions of the length requirement of roll shaft and the spacing of heat-resisting rib.
Preferably, the end set of described rib has taper surface；Described collars and fire resisting pouring material pour height
Degree mutually maintains an equal level with taper surface bottom.
Beneficial effect：The utility model has the advantages that：
(1) do not have the expensive heat-resisting steel material of integral installation between the heat-resisting rib of the utility model, but between being mounted with
Every the collars of uniform sheet, fire resisting pouring material is filled between collars, fire resisting pouring material is staggered with collars, the thickness of collars
Degree is only arranged to 1-10mm, and the roll surface overwhelming majority being so in contact in conveying with high temperature billet steel is fire resisting pouring material, is reduced
High temperature billet steel is transferred to the heat of roll shaft by collars, so that roller reaches heat-insulated resistant to elevated temperatures purpose；And so set
The rolled steel dosage for reducing roller is put, manufacturing cost instead of transmission, can greatly be reduced by cheap fire resisting pouring material；
(2) roll shaft front end of the present utility model is additionally provided with swivel joint, and inside is then provided with water-cooling channel, and rotation connects
Head can external installation chilled water unit, cooling water is flowed into water-cooling channel from swivel joint, takes away the heat on roll shaft, so as to reach
To the purpose of cooling roll shaft, significantly can cool to roll shaft.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model is furtherd elucidate, the present embodiment is with the utility model
Implemented under premised on technical scheme, it should be understood that these embodiments are merely to illustrate the utility model rather than limit this reality
With new scope.
As shown in figure 1, a kind of resistant to elevated temperatures roller structure of effectively insulating, including a roll shaft 1；Both ends are each on the roll shaft 1
One heat-resisting rib 2 is installed, and the evenly spaced collars 3 of a row is additionally provided between the heat-resisting rib 2 in both sides, described collars 3
It is similarly installed on roll shaft 1, and fire resisting pouring material 4 is filled between adjacent collars 3 and between collars 3 and heat-resisting rib 2；
The external diameter of described collars 3 is less than the external diameter of heat-resisting rib 2, and pouring for fire resisting pouring material 4 is highly at a stalemate with the external diameter of collars 3
It is flat.
The one end of described roll shaft 1 is additionally provided with swivel joint 5；And the inside of roll shaft 1 is additionally provided with and swivel joint 5
The water-cooling channel 6 being connected；Described collars 3 is laminated structure, and the thickness of collars 3 is arranged to 1-10mm.Described collars 3
Altogether at least provided with three, and the then relative set of fire resisting pouring material 4；The quantity of described collars 3 can be wanted according to the length of roll shaft 1
Ask and the corresponding setting of the actual conditions of the spacing of heat-resisting rib 2.
The end set of described rib 2 has taper surface 21；Described collars 3 and fire resisting pouring material 4 pour height with
Taper surface bottom mutually maintains an equal level.
Do not have the expensive heat-resisting steel material of integral installation between the heat-resisting rib of the utility model, but be mounted with that interval is equal
The collars of even sheet, fire resisting pouring material is filled between collars, fire resisting pouring material is staggered with collars, and the thickness of collars is only
1-10mm is arranged to, the roll surface overwhelming majority being so in contact in conveying with high temperature billet steel is fire resisting pouring material, reduces height
Warm steel billet is transferred to the heat of roll shaft by collars, so that roller reaches heat-insulated resistant to elevated temperatures purpose；And so set and subtract
The rolled steel dosage of few roller, manufacturing cost instead of transmission, can greatly be reduced by cheap fire resisting pouring material.
Roll shaft front end of the present utility model is additionally provided with swivel joint, and inside is then provided with water-cooling channel, swivel joint
Can external installation chilled water unit, cooling water is flowed into water-cooling channel from swivel joint, takes away the heat on roll shaft, so as to reach
The purpose of roll shaft is cooled down, significantly can be cooled to roll shaft.
