Abstract
The invention relates to the industrial kiln material field and provides a lightweight porous heat insulation brick. The brick is formed through adding a combustible filler to main raw materials comprising lightweight porous perlite having a granularity of below 250mum, high-aluminum lightweight processed sands, fine magnesite powder, refractory clay and the like, carrying out mechanical pressing, and sintering in a high-temperature tunnel kiln. The brick has the characteristics of small heat conduction coefficient, high compressive strength, good heat shock resistance and the like, and is suitable for the heat insulation of inner liners of metallurgical coke ovens, hot-blast stoves and heating furnaces.
Description
Technical field:
The invention provides a kind of light porous heat-insulating brick, relate to the Industrial Stoves Material Field.
Background technology:
It is all difference of hardness, intensity difference that insulating fire brick main raw on present China market mostly is the rock that boils, diatomite, Pumice, expanded vermiculite etc., and general granularity is all very large, with heat insulating goods or the light-weight refractory goods of its system, intensity, the poor large shortcoming of thermal insulation are arranged.
Summary of the invention:
The objective of the invention is to design and a kind ofly have that thermal conductivity is little, compressive strength is high, good thermal shock stability light porous heat-insulating brick.
The technical scheme that the present invention takes is: take light porous granularity as perlite below 250 microns, the ripe sand of high-alumina lightening, magnesite fine powder, fireclay etc. is as main raw material, mixes flammable weighting material, burn till through mechanical pressing, hyperthermia tunnel Kiln.
Because the present invention has taked technique scheme, compared with prior art, have the advantages such as thermal conductivity is little, compressive strength is high, good thermal shock stability.
Claims (1)
1. light porous heat-insulating brick is characterized in that: take light porous granularity as perlite below 250 microns, the ripe sand of high-alumina lightening, magnesite fine powder, fireclay etc. is as main raw material, mixes flammable weighting material, burn till through mechanical pressing, hyperthermia tunnel Kiln.
