Abstract
The utility model relates to a groove refractory slab and belongs to the field of kiln furniture. The groove refractory slab is characterized in that a plurality of grooves are formed in the upper surface or / and the lower surface of a refractory slab body, the grooves enter the refractory slab body from one side edge of the refractory slab body and extend to the other side edge of the refractory slab body. According to the groove refractory slab, a common refractory slab surface is designed to be of a groove structure, the grooves extend from one side edge to the other side edge, flames in a kiln can pass through the grooves, and therefore, the groove refractory slab is quite good in flame permeating performance. Meanwhile, due to the design of the grooves, the weight of the groove refractory slab is reduced, self absorption of heat is lowered, and an energy-saving effect is achieved.
Description
Technical field
The utility model relates to a kind of kiln furnitures, particularly relates to a kind of carrying refractory slab kiln furnitures.
Background technology
In high temperature kiln, refractory slab plays a part carrying and is heated workpiece and fires in kiln, is that kiln is fired the indispensable high temperature resistant carrying tool of workpiece.For increasing work efficiency, fire workpiece and piled up on the refractory slab, be superimposed upon on the kiln car from level to level again.But for some workpiece, in its bottom that contacts with refractory slab may be sealed in, become the dead angle of firing, can not enter flare, heat exchange is insufficient, causes and fires not exclusively, become bad portion processed product, such as the bottom of cup, dish, bowl, dish, even adopt the hollow refractory slab, can not make flare directly see through the bottom and fire.
Summary of the invention
At the defective in the above-mentioned field, the utility model provides a kind of groove refractory slab, can make the bottom of firing workpiece fiery thoroughly, and workpiece is fired fully, reduces the generation of substandard products, can alleviate the weight of refractory slab simultaneously again, reduces the absorption of heat, reaches energy-conservation effect.
The groove refractory slab is characterized in that: or/and lower surface is provided with some grooves, described groove enters from a side of refractory slab on refractory slab, extends to another side of refractory slab.
Described groove is the parallel lines groove.
The shape of cross section of described groove is trapezoidal, square or semicircle.
Described refractory slab is square, circular, rectangle or trapezoidal.
The width of described groove is identical with width between the adjacent trenches.
The shape of cross section of described groove is up big and down small trapezoidal, and described groove is positioned at a surface of refractory slab.
The utility model groove refractory slab, offer parallel groove on the surface of refractory slab, because being a side from refractory slab, groove extends to another side, therefore will fire workpiece piles up when fluted this one side, fire in its kiln is to shuttle from the bottom of firing workpiece, and the bottom of firing workpiece can have naked light to fire equally.For easy to process, can be with trench design in echelon, square or semicircle, and be straight-line groove.
Preferably, refractory slab is square, and groove is parallel with a side of refractory slab.
More preferably, the width of groove is identical with width between the adjacent trenches, and there is on half area fire thoroughly on the refractory slab surface.
From use angle, if having only a face to pile up, refractory slab fires workpiece, only need be at a surface design groove of refractory slab; Sometimes refractory slab is that positive and negative uses repeatedly, and can there be groove on the two sides, and the shape of cross section of preferred groove is trapezoidal.
The utility model becomes the plough groove type structure with common refractory slab surface design, and groove extends to another side from a side, flare in the kiln can pass through in groove, therefore the saturating bad temper of this groove refractory slab is very good, simultaneously because the plough groove type design, make the weight saving of refractory slab, heat absorption reduces certainly, has played energy-conservation effect.
Description of drawings
Fig. 1 vertical view of the present utility model,
Fig. 2 front view of the present utility model,
Each label lists as follows among the figure:
1-refractory slab, 2-groove.
The specific embodiment
As shown in Figure 1 and Figure 2, be evenly distributed with some parallel straight-line grooves 2 on the surface of square refractory slab 1, described groove 2 extends to opposed side edges from a side of square refractory slab 1, therefore piled up when firing workpiece on the utility model groove refractory slab, can be fiery thoroughly in the groove 2, make the bottom of firing workpiece can be fired by naked light in the same old way, do not have the dead angle.This groove can be arbitrary shape, arrange arbitrarily, as long as a side from refractory slab 1 of groove 2 is extended down to another side, the form that forms saturating fire just can, and groove 2 can be arranged on two surfaces of refractory slab 1.
The cross section of preferred this groove 2 can be semicircle, square or trapezoidal, and the preferred cross section of the utility model is up big and down small trapezoidal, and the distance between the groove and groove are with wide.Because workpiece only piles up on a face of groove refractory slab, so the preferred groove of the present invention only is positioned at a surface of groove refractory slab, and in like manner, groove is that can be arranged on two of groove refractory slab lip-deep.
The utility model becomes the plough groove type structure with common refractory slab surface design, and groove extends to another side from a side, flare in the kiln can pass through in groove, therefore the saturating bad temper of this groove refractory slab is very good, simultaneously because the plough groove type design, make the weight saving of refractory slab, heat absorption reduces certainly, has played energy-conservation effect.
