Corrosion Resistant Magnesia Ferrum Spinel Refractory Brick

Product Specification

Hgih Quality Good Corrosion Resistance Magnesia Ferrum Spinel Refractory Brick

Magnesia iron spinel brick is made of high quality synthetic spinel raw materials and made a special process, the magnesia iron spinel bricks have high crushing strength, good thermal shock resistance, thermal creep characteristics of good performance, high refractoriness under load, but magnesite iron spinel brick also has direct combination magnesite chrome brick is easy to stick to hang the characteristics of the kiln, solved the cement kiln with magnesite chrome bricks in use process to generate the problem of hexavalent chromium pollution to the environment.

Magnesia Iron Spinel Brick Description

Magnesium iron spinel refractory brick has the excellent kiln skin properties of dolomite brick and magnesia chrome brick, the magnesia iron spinel brick has high refractoriness and strong anti oxidation and reduction and mechanical stress functions. There are significant improvements. Magnesia iron spinel firebrick has the characteristics of high compressive strength, good thermal shock resistance, good thermal creep resistance, erosion resistance and permeability, high load softening temperature, and magnesia iron spinel firebrick also easier to stick kiln skin than direct combination of magnesia chrome brick. The characteristics can effectively solve the problem of causing pollution to the environment by generating hexavalent chromium during the use of magnesia chrome bricks for cement kiln.

Properties of Magnesia Iron Spinel Brick

.Low thermal expansion coefficient,

.Alkali slag resistance,

.Spalling resistance,

.Good creep resistance,

.Good thermal shock resistance.

Manufacturing Process of Magnesia Iron Spinel Brick

Magnesia iron spinel fire brick uses high purity magnesia sand and Al Fe spinel sand as the main raw materials through reasonable proportioning, high pressure molding, strictly control over the firing temperature and firing atmosphere to make the magnesium iron spinel fire brick has good flexibility and thermal shock stability, and no hexavalent chromium pollution for cement kiln burning zone. The product is high volume stability, high load softening temperature, excellent thermal shock, sticking kiln coating properties

Advantages of Magnesia Iron Spinel Brick

Magnesia iron spinel firebrick has the advantages of small thermal expansion coefficient and high thermal conductivity, which can significantly reduce the thermal stress of the refractory magnesium iron spinel brick. Due to different thermal expansion coefficients of various phases, in firing During the process, a large number of microcracks are present inside the material, thereby increasing the toughness of the material. Therefore, the magnesia alumina spinel brick has good flexibility and thermal shock resistance.

Application of Magnesia Iron Spinel Brick

Magnesium iron spinel firebrick has been widely used in firing belts and upper transition belts in the cement rotary kiln, becoming a new variety to replace magnesia chrome bricks in conventional raw fuel production lines. And magnesia iron spinel firebrick is used as working linings of burning zone in various cement kiln such as Lepol kiln, wet process kiln and new dry cement kiln.
