Rebonded Fused Magnesia Chrome Brick

MAGSCIE BRAND: RMK

Introduction

Rebonded Fused Magnesia Chrome Brick(RMK)made of fused mag-chrome, magnesite and chromite, processed by ultra-high temperature firing. This product has been developed that contain fused magnesite-chrome grains to offer improved slag resistance. Fused magnesite-chrome grain has extremely low porosity and is chemically inert. In addition, bricks made from these grains have a tendency to shrink on burning rather than expand. As a result of these features, the rebonded fused magnesia chrome brick (RMK) has lower porosity and superior slag resistance as compared to direct-bonded magnesia chrome brick (DMK).

Properties

· Excellent thermal shock stability, oxidation-reduction resistance, thermal fatigue resistance, wear resistance and erosion resistance.

· Ultra-strong resistance to slag attack and vacuum damage.

· Can be used under vacuum refining condition, or strong oxidation atmosphere, or ultra-high temperature liquid erosion, or high alkaline slag and frequent alkalinity changes slag attacks.

· The irreplaceable, the longest service life and the most economical furnace lining refractory.

After Impregnation process treatment, the physical and chemical properties of RMK are greatly improved. The porosity will be reduced by 7%, the bulk density will increase by 0.05g/cm3, and the Cold Crushing Strength will increase by about 30MPa. This is an additional procedure.

Applications

· Vacuum refining furnaces (e.g. RH degasser, VOD degassing ladles)

· Argon Oxygen Refining Furnaces (e.g. AOD Converters)

· Non-ferrous smelting big furnaces (e.g. IC3 Refining Converters, Pierce Smith Converters, Noranda Furnaces, Outokumpu Flash Smelting Furnaces)

· Ultra-high power EAF furnace

· Used at key parts of refining furnaces under very harsh conditions, e.g. Working linings, hot spots, slag line zone, tuyere zone, erosion zone and easily damaged parts of big furnaces.
