Synthetic Magnesia Refractories

    The synthetic magnesia refractories we now export are fused magnesia chromite, high iron and high lime synthetic magnesia, high lime and low silicon synthetic magnesia. 


1. Fused Magnesia Chromite

 

    This product is made from sorted high quality caustic calcined magnesite powder and chromite concentrate through blending, briquetting and smelting in electric arc furnace. It featured by good rate of direct bonding, high purity, big size of crystalline, etc which is essential material for making high grade magnesia chromite bricks.

2. High Iron and High Lime Synthetic Magnesia

    This product is made from caustic calcined magnesite and iron powder through evenly grinding, briquetting or balling, high temperature sintering in rotary kiln or shaft kiln. It featured by high density, high strength, high resistance against corrosion, good thermal resistance and volume stability. It is widely used in ramming bottom and slope of electric arc furnace. 

    MTS-A is made in shaft kiln whilst MTS-B in rotary kiln.
