Magnesia brick

The refractoriness of magnesia bricks can reach above 2000 °C.Magnesia bricks have a higher thermal conductivity and are second only to carbon bricks and silicon carbide bricks in refractory products, which decrease with increasing temperature.Magnesia bricks have poor resistance to acid slag and cannot be directly contacted with silica bricks when used.

Nanme：Magnesia brick

Other name:Magnesite brick

Characters：high refractoriness,high thermal conductivity

Application：open hearth furnace,bottom and wall of the EAF,conventer, high temperature tunnel kiln,cement kiln,lime kiln, glass furnace regenerator

Magnesia zircon brick

Magnesia zircon brick is used in the middle and upper part of the lattice of the glass kiln regenerator, without clogging and collapse, and the service life can reach more than 8 years. Its high temperature strength and thermal stability are better than re-combined magnesia bricks, and it has a good use prospect in the glass kiln regenerator.

Magnesia chrome brick

Magnesia chrome brick is an alkaline refractory product, which is made of periclase and magnesia chrome spinel, and is fired at 1600~1800 °C in an oxidizing atmosphere. It can also be made into non-burned brick by chemical bonding agent such as water glass.

Nanme：Magnesia chrome brick

Other name:Magnesite chrome brick

Characters：large pores and isolated, dense, high strength, corrosion resistant and sensitive to temperature changes

Application：vulnerable parts of steelmaking electric furnace, RH, DH vacuum degassing device, secondary refining slag line parts such as VOD, LF, ASEA-SKF, AOD, steelmaking converter, cement rotary kiln and glass melting Kiln regenerators

magnesia alumina spinel brick

The magnesia-aluminum brick is dominated by periclase, and the magnesia-alumina is used as the matrix, which is superior to the magnesia brick in thermal shock resistance.In order to improve the thermal shock resistance of the magnesia brick, alumina or bauxite clinker fine powder is introduced into the furnish to form a magnesium aluminum spinel matrix, thereby preparing a magnesia-aluminum brick.

Nanme：magnesia alumina spinel brick

Other name:magnesia alumina spinel brick

Characters：good thermal shock resistance, high refractoriness under load

Application：top of steel making open-hearth furnace and EAF, cement kiln, large-scale cement rotary kiln and non-ferrous metal smelting furnaces, etc.
