Abstract
The invention relates to a ceramic roller for a glass tempering furnace. The ceramic roller comprises a roller way (1), both ends of which are in fixed connection with two shaft heads (2), the cylindrical surface of the roller way (1) is provided with ring columns (3) arranged at interval along the axial direction, the ring columns (3) are a ring column group formed by first ring columns (31) and second ring columns (32) that have opposite gaps and identical outer circumferential diameter. The ceramic roller adopting the structure can make heating of the glass bottom surface more uniform, improve tempering quality and reduce the risk of glass rupture.
Description
Technical field
The present invention relates to a kind of ceramic roller for glass tempering furnace, belongs to glass tempering technology field.
Background technology
Widely, wherein key factor is using ceramics for roller bed type horizontal annealing furnace application both at home and abroad at present
Roller is used as the conveyer device for softening glass.The glass of soft state is on Quartz Ceramic Roller in whole production process
Operation can not deform, can not produce scuffing, therefore, ceramic roller is critical component in glass tempering furnace.
If plate glass enters condition of high temperature thermal stress inequality from room temperature, have and burst phenomenon generation, its main original
It is high because being the ceramic roller heat conduction efficiency that transport is used, make lower glass surface temperature higher than upper surface temperature, produce
The excessive thermal stress of life, damages.
Existing ceramic roller increases ventilating duct to solve this problem, such as Chinese patent from contact area is reduced
(CN203999345U) a kind of ceramic roller disclosed in.It is provided with the annulated column at interval to reduce ceramic roller and glass
Contact area, but because the position that glass is contacted in traveling with annulated column can contact all the time with annulated column, this part
Temperature can be higher than peripheral temperature, and because annulated column is solid construction, one side conduction of heat is fast, another aspect annulated column
Itself there is stronger heat storage capacity, can all cause glass bottom surface to be heated inequality, easily produce thermal stress in bottom surface,
Cause tempering Quality Down, or even glass rupture occur.
The content of the invention
It is an object of the invention to provide it is a kind of can make that glass bottom surface is heated evenly for glass tempering furnace
Ceramic roller.
For achieving the above object, the present invention includes a roller-way, and its two ends is fixedly connected two spindle noses, roller-way
There are annulated column, the axially spaced setting of annulated column on the face of cylinder, the annulated column is breach reversely opposed and excircle diameter
The annulated column group that the annulated column of identical first and the second annulated column are formed.
Preferably, the breach longitudinal length is the 1/4 to 1/3 of the first annulated column excircle diameter.
Further, first annulated column and the second annulated column are hollow structure.
By the way that annulated column is arranged to by breach reverse opposed and the first annulated column of excircle diameter identical and the second ring
The annulated column group of cylindricality composition, can make to reduce specific part and annulated column time of contact in glass traveling process, and then
The time of conduction of heat is reduced, reduces thermal stress, by the opposed stable type for ensureing glass run of breach.By annulated column
Being set to hollow excuse can reduce the pyroconductivity of annulated column, simultaneously because the convection current in stove can ensure to the greatest extent annulated column
Temperature it is consistent with furnace air, further reduce thermal stress.

Embodiment
The present invention is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2 and shown in Fig. 3, the ceramic roller includes a roller-way 1, and its two ends is fixedly connected two
Individual spindle nose 2, there is annulated column 3, the axially spaced setting of annulated column 3 on the face of cylinder of roller-way 1, it is characterised in that
The annulated column 3 is breach 4 reversely opposed and excircle diameter identical the first annulated column 31 and the shape of the second annulated column 2
Into annulated column group.Wherein the longitudinal length of breach 4 is the 1/4 to 1/3 of the excircle diameter of the first annulated column 31.It is described
First annulated column 31 and the second annulated column 32 are hollow structure.
Annulated column is arranged to by breach reverse opposed and the first annulated column of excircle diameter identical and the second Ring-cylindrical
The annulated column group of composition, can make to reduce specific part and annulated column time of contact in glass traveling process, and then reduce
The time of conduction of heat, reduce thermal stress, by the opposed stable type for ensureing glass run of breach.Annulated column is arranged
For the pyroconductivity that hollow excuse can reduce annulated column, simultaneously because the convection current in stove can ensure to the greatest extent the temperature of annulated column
Degree is consistent with furnace air, further reduces thermal stress.
