Lev3 Высокий ароматический кирпич введение

Lev3 high alumina brick is one of the common refractory materials, которые формируются и калькулируются из боксита или другого сырья с высоким содержанием глинония.

Characteristics of grade 3 high alumina bricks

1. Chemical composition: AI203 content should be between 50% и 70%, Si02 content should be below 30%
2. Объемная плотность: should be above 2.20 g/cm’.
3. Кажущаяся пористость: should be below 22%.
4. Normal temperature compressive strength: should be above 40MPa.
5. Температура размягчения нагрузки: should be above 1350’C.
6. Устойчивость к термическому удару: should be above 10 раз.
7. Коэффициент теплового расширения: should be below 5.0×10-6/С.

Application of Lev3 high alumina brick

• Used for lining blast furnaces, hot blast furnaces, electric furnace roofs, blast furnaces, reverberatory furnaces, and rotary furnaces.
• Refractory heat expansion rate is small, not easy to deform, neatly formed
• Carefully selected materials insist on quality first, preferred materials are durable
• The clay is very pure and fine, has high density, is not easy to wear on the surface, has high-temperature resistance, high compressive strength, high load softening temperature, high-temperature volume, stability, and deformation performance are excellent
