Product details
describe
High alumina anchor bricks refer to high alumina refractory bricks with specific shapes installed on steel structures supporting industrial kiln shells or lining, and embedded in refractory lining for their anchoring and linking functions.
High alumina anchor bricks are divided into three grades according to their physical and chemical indicators: LM-55, LM-65, and LM-75; Among them, L and M are the first letters of the Chinese Pinyin for aluminum and anchor, respectively.
The size of anchor bricks can be customized, processed and produced according to customer requirements.
Performance indicators of high alumina anchor bricks
| project | LM-55 | LM-65 | LM-75 |
|---|---|---|---|
| ω(Al2O3)/% ≥ | 55 | 65 | 75 |
| ω(CaO)/% ≤ | 2 | 2 | 2 |
| Room temperature compressive strength/MPa ≥ | 50 | 50 | 55 |
| Tensile strength at room temperature/MPa ≥ | 4 | 4.1 | 4.2 |
| 0.2MPa load softening starting temperature/℃ ≥ | 1450 10 |
1500 10 |

| Visible porosity/% ≤ | 22(24) 1.5 |
23(24) 1.5 |
21(23) 1.5 |
| Bulk density/(g/cm ³) | 2.3 | 2.35~2.40 | 2.50~2.60 |
| Heating permanent line change/% (1500 ℃× 2h) | -0.4~+0.2 | -0.3~+0.2 | -0.3~+0.2 |
| Note 1: Bulk density is a reference indicator for the weight of bricks used in design and is not subject to assessment. | |||
| Note 2: The values in parentheses are indicators for bricks with a single weight greater than 12kg. | |||
