¿Cuáles son los usos de rendimiento de ladrillos de magnesia cromo?

Magnesia chrome bricks are refractory products containing Cr2O3≥8% made by adding chromite to sintered magnesia as raw materials. The main mineral phases are periclase and chromium-containing spinel (MgO.Cr2O3).

Magnesium chrome bricks have certain resistance to alkaline slag erosion, good volume stability at high temperatures, and little shrinkage when reburned at 1500°C. The main disadvantage is that after the chromium spinel absorbs iron oxide, the structure of the brick is changed, causing “inflation” and accelerating the damage of the brick.

Los ladrillos de magnesio y cromo se utilizan a menudo para construir hornos de fundición de cobre, hornos eléctricos, hornos rotativos y ciertas partes de hornos abiertos.
