High Crushing Strength Magnesia Chrome Brick For Cement Plant Kiln

High Crushing Strength Magnesia Chrome Bricks for Cement Plant Kiln

Natural fused ore or its selected products and sintered magnesia made of natural or synthetic raw materials are the basic raw materials for the manufacture of magnesia chrome bricks. Ordinary magnesia chrome bricks or silicates combined with magnesia chrome bricks (containing 4% to 7% SiO2) combined with a lower melting point of the cinnamate phase (calcium-magnesium olivine CMS and magnesium-scruzzo C3MS2) combined with high refractory Magnesia and chrome, iron and aluminum composite magnesium spinel are formed, so it has high high temperature plasticity and microstructure toughness. It shows stress relaxation above 800 °C and good thermal shock stability. It is most suitable for 1000t. Used in small kiln below /d. However, its load softening temperature is low, and it is easy to be damaged by overheating, so it is rarely used in large precalcining kiln (≥4000t/d).

Magnesia-chrome bricks with low silicate content (including 2.5%~4% SiO2) still have certain microstructure toughness and high temperature stability, which is suitable for use in rotary kiln of 1500~4000t/d. It can also be used on both sides of the firing zone in the larger format rotary kiln. This brick can be referred to as a semi-direct combined magnesium chrome brick.
