Basic Oxygen Furnace Refractories

The Basic Oxygen Furnace (BOF), is a tilt-able vessel lined with refractories such as magnesia carbon brick. The main function of the BOF is to decarburize the hot metal using pure oxygen gas.

Argon-Oxygen Decarburisation (AOD) Refractories

More than 30 years ago, most AOD Linings were constructed with Magnesia Chrome refractories. Over time the AOD linings were switched to Fired Dolomite and Fired Magnesia Enriched Dolomite. Today, virtually all AOD Linings are now constructed with these refractories.

The switch to Fired Dolomite and Fired Magnesia Enriched Dolomite has reduced refractory cost and improved Stainless Steel quality. After AOD operators switched from Magnesia Chrome refractories to Dolomite refractories, AOD Lining designs have evolved over the years, as well. Now, many lining design use three grades of dolomite; resin bonded, fired dolomite and fired magnesia enriched dolomite. Linings are also zoned by thickness.
