GLOBAL UPDATE OF MAGNESITE RESOURCES

201584 korea magnesia clinker industry group kmcig in 2011 production of magnesia was 255000 tonnes with 67 ccm 23 dbm and 10 fm in 2012 output is estimated by kmcig to have decreased by around 30 to 178000 tonnes difficulties in supply of coal and transportation are the main reasons for this decrease

Paper

201752 Carbon bonded magnesia and magnesiaalumina bricks are used in the side walls and bottom of steel ladles for more than 30 years They have to withstand aggressive steel/slag systems in the range of 1600–1750 °C and also provide an excellent thermal shock performance During service or presintering alumina is able to react with magnesia to

Magnesia Forms Appliions and Production Processes

200243 Magnesia Forms Appliions and Production Processes Fused Magnesia MgO is normally manufactured by the electric arc melting of caustic calcined magnesia deadburned magnesia or raw magnesite in furnaces at temperatures in excess of 2750°C producing a refractory product whose altered crystalline structure is such that its

Recycling of refractory bricks used in basic steelmaking

201911 One of the most widespread appliions for spent refractory brick is the use as roadbase aggregates However leaching of heavy metals such as Cr must be assessed prior to use to avoid environmental impact Domínguez et al 2010 Prehydration may also be required to avoid expansion problems during use particularly for magnesia bricks

Magnesia Magnesium Oxide MgO Properties

200126 Magnesia bricks often in coination with spinel or chrome are also used in ferroalloy nonferrous glass and cement industries Castables and sprayables based on magnesia are widely used for basic refractory linings for steel transfer appliions The lime to silica ratio present in the magnesia has a major influence on its properties Crucibles
