refractory bricks for ladlethe use and classification of aluminum magnesium spinel
Introduction of Aluminum Silicate Refractory Bricks for
· High alumina bricks refer to an aluminum silicate refractory with an Al2O3 content of more than 48 . It can be classified according to its mineral composition generally divided into five types of refractory bricks low mullite mullite mullite-corundum corundum-mullite and corundum.
Application Of Non Burning Magnesia Brick And Aluminum
· Compared with MgO-C brick and Al2O3-C brick the graphite content of aluminum magnesium carbon brick is less generally 6 12 so it has body. The characteristics of high density low porosity and high strength are presented. The production technology of aluminum magnesium carbon brick is the same as that of MgO-C brick.
Classifications of High Temperature Refractory Castable
High-temperature light-weight refractory castables this kind of refractory castables usually use corundum or high-alumina mullite clay magnesium and magnesium aluminum spinel and other light particles or hollow balls as aggregate.
Types of Refractory Materials and Their Applications
· Various refractory bricks in different sizes and shapes are now available for diverse applications. The typical refractory materials include fireclay refractories high alumina refractories

With the increase of the temperature of molten steel in the ladle and the increase of temperature. With the extension of residence time the clay brick lining is seriously eroded.
Spinel Refractory MaterialDXD
Spinel Spinel refers to a class of minerals with the same structure. The chemical formula can be expressed as AO · R2O3 where A represents a divalent element ion which can be Mg2 Fe2 etc . R is a trivalent element which can be Al3 Fe3 Cr3 and so on. Most of them exist in the form of isomorphous solid solution. All spinel forms a solid solution by expanding the crystal
Refractory Material for Tunnel KilnRongsheng Refractory
· 4) Refractory material for tunnel kiln need use magnesium-aluminum bricks at 1500 ℃ 1600 ℃ 5) Tunnel kiln refractory use corundum brick below 1800 ℃ At the same time in order to reduce the heat dissipation of the kiln wall light clay bricks and light silica bricks are built in the middle and outer walls of the kiln wall.
Tundish of Refractory MaterialsInsulating Bricks
The permanent layer thickness of medium and small sized tundish is generally around mm and the thickness of large tundish is around mm. Matters need attention of tundish refractory. The steelmaking process of the steelmaking plant can directly influence the refractory materials used in the tundish and the types of use.
What are the main ingredients of refractory bricks
