Introducción de ladrillo de alúmina LEV3

Lev3 high alumina brick is one of the common materiales refractarios, que se forman y calcinan a partir de bauxita u otras materias primas con alto contenido de alúmina.

Characteristics of grade 3 ladrillos con alto contenido de alúmina

1. Composición química: El contenido de AI203 debe estar entre 50% y 70%, Si02 content should be below 30%
2. Densidad a Granel: should be above 2.20 g/cm’.
3. Porosidad aparente: should be below 22%.
4. Normal temperature compressive strength: should be above 40MPa.
5. Temperatura de ablandamiento de carga: should be above 1350’C.
6. Resistencia al choque térmico: should be above 10 veces.
7. Coeficiente de expansión térmica: should be below 5.0×10-6/C.

Application of Lev3 high alumina brick

• Used for lining blast furnaces, calzoncillos calientes, electric furnace roofs, blast furnaces, hornos reverberatorios, 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, alta resistencia a la compresión, high load softening temperature, high-temperature volume, stability, and deformation performance are excellent
