Applications:
⒈ To 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 against 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.
