Item:Fused Magnesia Alumina Spinel
Made from high quality alumina and light-burned magnesia in electric arc furnace.
The fused magnesia-alumina spinel has outstanding refractoriness, good erosion resistance, high anti-corrosion, high resistance against flaking, good thermal stability, high temperature resistance, high slag-resistance, good thermal shock resistance, etc. It also has high true density, low water absorption, low thermal expansion coefficient ,good thermal stability and good thermal shock resistance.
Applications：⒈To replace magnesia chrome sand to make high grade refractory bricks in lining bricks for cement rotary kiln to avoid chrome pollution and has higher resistance againt flaking.
⒉Used to make refractory castables for ladles to improve anti-corrosion of steel plate lining. It is widely applied in refractory material, steel smelting, cement rotary kiln and glass kiln.
⒊As an ideal material to make continuous casting sliding plate, ladle lining brick, nozzle bricks, continuous casting nozzle and open hearth bricks. Also as a basic material in big large cement kiln, bricks in transition zone of neutral cement kiln and kiln furniture for medium and high temperature applications.
