Magnesia Alumina Zirconia bricks are produced on the basis of low thermal magnesia-alumina bricks by adding ZrO2.
The micro-pore structure inside the products improves theirs thermal shock resistance.Meanwhile, Zirconia easily reacted with CaO forming calcium zirconate with high melting point in application,which improves the corrosion resistance of the produce and adhesion of kiln material.
Mainly used in the calcining zone of dry-process cement rotary kiln.
Magnesia-Alumina Spinel brick (HLMLJ), as chrome free produces , are specially developed for the transition zone of large scale dry-method cement kiln.
Application include but not limited to the transition zone in proof of EAF, basic oxygen furnace, steel ladle, cement rotary kilns glass tank regenerators and lime kilns.
Magnesium aluminum spinel brick with low porosity, high strength, good thermal shock stability, corrosion resistance and other excellent features, improve the life of rotary kiln lining.
High pure magnesia is produced by light burning, fine grinding, dry ball indentation and sintering in extra high temperature oil shaft kiln shaft kiln with superior magnesia as raw material.
With MgO content over 97%, Low impurity content, direct combination of periclase crystal body as well as firm and tight structure, it is an ideal raw material to produce high-class basic bricks and unshaped refractory materials.
Fused- Rebonded Magnesia-Chrome Bricks are made of fused magnesia-chrome clinker, and mainly used in refining furnace such as AOD, VOD, RH, DH, SKF etc.

Direct-Bonded Magnesia-Chrome Bricks and Semi direct -bonded Magnesia-Chrome bricks Direct are composed of high-purity or secondary-purity or fused magnesia and chrome concentrate.
Glass phase concentrate in the triangle zone of the crystalline phases. Which are directly bonded to each other.
The produces are characterized by low-porosity. high cold crushing strength. Strong resistance to abrasion, corrosion, thermal shock and spilling.
Magnesia-Calcium Bricks are made of two set burned Magnesia-Calcium sands and high pure Magnesia.
After high pressure shaped,high temperature burned and paraffine vacuum dipped. They have good high temperature creep-resistance and slag resistance.
They are the best materials for AOD ,VOD.
