Abstract
There is an insulating fire brick for hollow structure, it is characterized in that: be processed with hollow cavity at described insulating fire brick close in 1/2nd scopes of non-working surface side; Suitable heat-barrier material can be clogged in hollow structure, also can not any material of filling.Insulating fire brick of the present utility model had both maintained the performance and used life of former refractory brick material, had good heat insulating function simultaneously, can reduce kiln surface temperature 50-200 DEG C, and energy-saving effect is remarkable, wide market.The utility model is applicable to all kinds of refractory brick particularly effectively cannot implementing heat-insulation and heat-preservation Industrial Stoves liner at all types of industries kiln.
Description
Technical field
The utility model relates to a kind of refractory material, relates to a kind of insulating fire brick with hollow structure specifically.
Background technology
Refractory brick is iron and steel, building materials, coloured, the hot industry inner lining of kiln such as chemical industry, electric power build indispensable basic material by laying bricks or stones, if be fabricated to compound heat-insulation structure, applied at elevated temperature can be met, again there is good heat insulating function simultaneously, to play an important role to saving energy in kiln consumption reduction, meet national industry development policies.
All types of industries kiln inner lining refractory block used is divided into working face (hot junction) and non-working surface (cold junction), when much kiln refractory brick often uses the thickness of 2/1 to three/2nds, kiln must overhaul, and refractory brick is changed again, and utilization rate is only 40-50%.For extending kiln service life, refractory brick needs enough compressive resistances, bulk density, high-temperature behavior, cause its thermal conductivity factor bigger than normal, in body of heater, amount of heat is delivered to body of heater surface by refractory brick, radiation loss is large, as all kinds of rotary kiln (as the production of cement, non-ferrous metal, lime, haydite, pelletizing etc.) the operating time phase is in operating condition, for preventing mechanical stress and wearing and tearing, can only build by laying bricks or stones with one deck refractory brick in cylindrical shell, light material cannot be used to carry out heat-insulation and heat-preservation, had a strong impact on the thermal efficiency of kiln.
Utility model content
The purpose of this utility model provides a kind of insulating fire brick with hollow structure for weak point existing in above-mentioned prior art just.Refractory brick of the present utility model has good heat insulating function, and kiln surface temperature can be made to reduce 50-200 DEG C, and energy-saving effect is remarkable, wide market.
The purpose of this utility model can be realized by following technique measures:
The utility model is processed with hollow cavity at described insulating fire brick close in 1/2nd scopes of non-working surface side.
Hollow cavity described in the utility model is the cavity running through insulating fire brick plane; The counter bore structure that described hollow cavity also can be closed for the one end processed in insulating fire brick plane; Described hollow cavity can also be the cavity of the concave structure of processing on non-working surface end face.
The heat-barrier material that the utility model is filled with rock wool, glass fibre, alumina silicate fibre, alumina fibre or is prepared from containing zirconium fiber in the hollow cavity of described insulating fire brick; Also the light heat-insulating material that diatomite, perlite, calcium silicates, clay, high alumina or mullite are prepared from can be loaded; Also can not any material of filling, form the heat-insulation chamber of hollow structure.
Hollow cavity described in the utility model can be the hollow cavity of the arbitrary shapes such as cuboid, square, ellipsoid.
The beneficial effects of the utility model are as follows:
1, technique simple possible, identical with existing refractory brick production technology, do not change the material characteristic of material own, do not affect service life;
The insulating fire brick 2, with this hollow structure is meeting under high temperature application and the prerequisite in service life, and have low thermal conductivity factor simultaneously, have good heat insulating function, can reduce kiln surface temperature 50-200 DEG C, energy-saving effect is remarkable;
3, the utility model is applicable to all kinds of refractory brick particularly effectively cannot implementing heat-insulation and heat-preservation Industrial Stoves liner at all types of industries kiln.

Detailed description of the invention
The utility model further describes below with reference to embodiment (accompanying drawing):
Embodiment 1
As shown in Figure 1, 2, the hollow cavity 2 of the present embodiment is arranged in 1/2nd scopes close to non-working surface 3 side of described insulating fire brick, and shown hollow cavity 2 is for running through the cavity of insulating fire brick plane.
The heat-barrier material that the utility model is filled with rock wool, glass fibre, alumina silicate fibre, alumina fibre or is prepared from containing zirconium fiber in the hollow cavity 2 of described insulating fire brick; Also the light heat-insulating material that diatomite, perlite, calcium silicates, clay, high alumina or mullite are prepared from can be loaded; Also can not any material of filling, form the heat-insulation chamber of hollow structure.
Hollow structure cavity described in the utility model can be the hollow cavity of the arbitrary shapes such as cuboid, square, ellipsoid.
Embodiment 2
As shown in Figure 3,4, the difference of the present embodiment and embodiment 1 is that described hollow cavity 2 is the counter bore structure that the one end processed in insulating fire brick plane is closed.
Embodiment 3
As shown in Figure 5,6, the difference of the present embodiment and embodiment 1 is that described hollow cavity 2 is the cavity of the concave structure of processing on non-working surface end face.
