What is the difference between magnesium iron spinel bricks and magnesium aluminum bricks?

answer

Magnesite spinel brick is a new generation of chrome free alkaline refractory used in the sintering belt of large Rotary kiln. It is a chrome free environmental protection product formed by high-temperature sintering of high-purity spinel using the characteristics of iron oxide solid melting in magnesium oxide. The product has the characteristics of high compressive strength, good thermal shock stability, good thermal creep resistance, corrosion and penetration resistance, and high load softening temperature. In addition, it also has the characteristics that it is easier to stick to the kiln skin than the directly bonded magnesia chrome bricks, which can effectively solve the problem of Hexavalent chromium generated during the use of magnesia chrome bricks for cement kilns, thus causing environmental pollution. Magnesium brick manufacturer

Magnesia alumina brick is an alkaline refractory material made by firing magnesium sand and a small amount of industrial alumina or bauxite as raw materials. The thermal stability is better than that of magnesium bricks, and the fire resistance is above 1580 ℃. Able to resist the erosion of alkaline slag. It is mainly used for the top of steel making open hearth furnace and electric furnace, high temperature tunnel kiln, large cement Rotary kiln and non-ferrous metal smelting furnace.
