furnace refractory bricks for Ladle furnace BOF BF preheating furnace electric arc furnace
Made of fused mag-chrome, magnesite and chromite;
processed by ultra high temperature firing.
With properties of very good thermal shock stability, oxidation-reduction resistance, thermal fatigue resistance, wear resistance and erosion resistance.
Especially with ultra strong resistance to slag attack and vacuum damage.
Under vacuum refining condition, or strong oxidation atmosphere, or ultra high temperature liquid erosion, or high alkaline slag and frequent alkalinity changes slag attacks．
They are proved to be the irreplaceable, the longest service life and the most economical furnace lining refractories.
Therefore they are widely used in the vacuum refining furnaces (eg. RH Gegasser, VOD degassing ladles), Argon Oxygen Refining Furnaces (eg. AOD Converters), ultra high power EAF furnace, non-ferrous smelting big furnaces ( IC3 Refining Converters, Pierce Smith Converters, Noranda Furnaces, Outokumpu Flash Smelting Furnaces), or used at key parts of refining furnaces under very harsh conditions, eg. Working linings, hot spots, slag line zone, tuyere zone, erosion zone and easily damaged parts of big furnaces.
