Refractory Magnesia Alumina Spinel Brick MAS For Cement Kiln

Product Specification

Refractory Magnesia Alumina Spinel Bricks (MAS) for cement kiln with quality guarantee

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).

Excellent thermal spalling resistance, good thermal shock stability.

Used for roof of open hearth, cement roary kiln. Etc.

FAQ

1.  What are refractory products?

Refractory products refer to functional materials which can resist high temperature or even ultra-high temperature. They are widely used in various high temperature heat treatment equipment, such as steels-melting kiln, glass kiln and cement kiln. The quality of refractory products directly affects the usable life of kilns and the quality of the final industrial output. Refractory products are made from various natural minerals such as silica, dolomite, graphite, zircon, magnesia, high aluminium ore and chrome ore through numerous technical refining processes. They have valuable features such as high-heat insulation, high-heat resistance, high strength, high hardness, good volume stability, oxidation resistance, excellent complexity, wear resistance, corrosion resistance, etc.. Some refractory products even have special features such as high ventilation, heat conduction and extreme hardness.

2.  Any differences between shaped and unshaped refractory products?

Shaped refractory products can be pressed into bricks and are, generally used in building heat treatment equipment such as metallurgical kilns. Unshaped refractory products refer to fire-resistant casting materials. They can be moulded into whatever shapes and are suitable for building different high temperature furnaces and using as the lining in different heat treatment furnaces.

Magnesia chrome brick • Instructions for use

Magnesia-chrome bricks are mainly used in metallurgical industries, such as the construction of open hearth furnace roofs, electric furnace tops, furnace refining furnaces, and various non-ferrous metal smelting furnaces. The high temperature part of the ultra high power electric furnace wall is made of fused cast magnesia chrome brick. The high erosive area of the refining furnace outside the furnace is made of magnesia chrome brick made of synthetic material. The high erosive area of nonferrous metal flash smelting furnace is made by melting cast magnesia chrome brick and synthetic material. Magnesia chrome bricks. In addition, magnesia-chrome bricks are also used in cement rotary kiln firing zones and glass kiln regenerators.
