Product brief:
Lightweight high alumina insulation brick is a new type of insulation material, which is mainly made of raw materials such as alumina, aluminum silicate and lightweight aggregate through proportioning, mixing, pressing, drying and firing. It is a high-efficiency, energy-saving and environmentally friendly thermal insulation material.
Lightweight high-alumina thermal insulation bricks are often used for thermal insulation and energy consumption reduction of high-temperature equipment in the fields of steel, building materials, chemicals, and electric power.
Technical data:
Al2O3 % | ≥48 | ||||||
Fe2O3 % | ≤2 | ||||||
Density g/cm3 ≤ | 1.0 | 0.9 | 0.8 | 0.7 | 0.6 | 0.5 | 0.4 |
Cold Crushing Strength ( Mpa ) ≥ | 3.9 | 3.4 | 2.9 | 2.5 | 1.5 | 1.5 | 0.8 |
Test Temperature ℃ | 1400 | 1400 | 1400 | 1350 | 1250 | 1250 | 1250 |
Thermal conductivity W/(mk.) 350℃ | ≤0.50 | ≤0.45 | ≤0.35 | ≤0.35 | ≤0.25 | ≤0.25 | ≤0.20 |
Product advantages:
Compared with the traditional lightweight refractory brick, the high-alumina lightweight brick has the following advantages :
The thermal conductivity is low, especially at high temperature, the thermal conductivity is relatively low, and the thermal insulation performance is good.
Good thermal shock resistance, the brick doesn't deform and peel under the use temperature range.
Higher load softening temperature and smaller reburning rate of change, make its use temperature higher, own longer life and better safety factor.
