Magnesia Alumina Spinel brick are made of basic refractory material and industrial alumina oxide or bauxite as raw materials. The Thermal shock resistance of magnesia alumina spinel bricks is better magnesia brick, and with high corrsive resistance to basic metal slag.
There are several grades of magnesia alumina spinel brick refractories :
| 1. | Magnesia 75 Alumina Spinel (MAS-75) Refractoriness point: 1600 oC Normal size: 230 x 114 x 65mm |
| 2. | Magnesia 80 Alumina Spinel (MAS-80) Refractoriness point: 1700 oC Normal size: 230 x 114 x 65mm |
| 3. | Magnesia 84 Alumina Spinel (MAS-84) Refractoriness point: 1750 oC Normal size: 230 x 114 x 65mm |
Magnesia Alumina Spnel Bricks are mainly used in open hearth furnaces and EAF, high temperature tunnel kiln, large scale cement rotary furnace, non ferrous metal smelting furnace, permanen line for ladles.
