Embodiment
With reference to Fig. 1 or Fig. 2, a kind of low heat conduction lining brick of novel concrete kiln of the utility model, including：Spinelle
Refractory brick 1, be arranged in spinel refractory bricks 1 and the refractory fiber floor 2 on surface；
Spinel refractory bricks 1 are vertically compressing using friction press or hydraulic press, and forming direction top and bottom are set
There is long stripes through hole 3, the side side of thickness thickness is provided with the groove 4 of prismatic table shape；No.1 chamfering 5 is set at 3 arris of through hole, it is recessed
No. two chamferings 6 are provided with 4 arris of groove；Spinel refractory bricks 1 are provided with long 8mm* wide 6mm* depths 4mm's in shaping upper surface
Strip nest mark 7.
As a preferred solution, the fire-retardent fiber felt-rug of respective shapes and thickness is filled at through hole 3, at groove 4
It is pasted with the fire-retardent fiber felt-rug of respective shapes and size.This fire-retardent fiber felt-rug has extraordinary heat-proof quality in itself.
It is further preferred that 5 radius of No.1 chamfering set at 3 arris of through hole is 8mm, two set at 4 arris of groove
Number 6 radius of chamfering is 5mm.It is such to set beneficial to shaping and demoulding brick output.
It is further preferred that the connection mode of through hole 3 and fire-retardent fiber felt-rug, groove 4 and fire-retardent fiber felt-rug is smearing strength
The mode of glue.This connection mode is very simple and convenient, and fixed effect is also more satisfactory.
It is further preferred that refractory fiber floor 2 is made of fire-retardent fiber felt-rug.Such setting can make full use of fire resisting fine
Tie up the heat-proof quality of felt in itself.
