MAGNESIA, ALUMINA MAGNESIA & ALUMINA SIC CARBON
Magnesia Carbon refractories are resin bonded with a blend of high crystal size seawater magnesia, fused magnesia and high purity graphite flakes. Suitable for use in the bottom/metal/slag zones of EOF, EAF, VAD, LRF, AOD. Excellent corrosion and oxidation resistance, non wetting characteristic, resistance to spalling and high hot strength are the keys to superior performance. Alumina Magnesia Carbon refractories are tailor made for specific LF/LRF/VAD/VD applications. Due to their unique chemistry they restrict joint openings in service and restrict metal penetration. Their high pyroplasticity provides an ideal solution for ladle impact areas. Alumina SiC Carbon Refractories are recommended for high wear areas of Torpedo and Hot Metal ladles.
Dense fired conventional Magnesia chrome bricks are offered for ferrous applications such as Ladle, LRF, AOD, VOD, EAF/EOF, RHF for both back up and working lining. The DBMC range is based on high grade magnesite chrome cosinter and fired at temperature >1750°c. These products exhibit good corrosion, erosion and thermal shock resistant and are suitable for Copper Smelters, Lead & Zinc Furnaces, AOD working lining and other Non Ferrous applications.
The range of fired magnesite bricks up to 94% MgO is suitable for use in backup applications of EAF, LD converter and steel ladles. Also used in utilities such as EAF sub hearth and working lining and hot metal mixer wear out lining. These can also be considered as low cost alternatives in non-ferrous and glassmaking applications.
SPECIAL BASIC REFRACTORIES
With the increased focus on fuel efficiency and furnace life in glassmaking, the use of high purity magnesite and magnesia zircon bricks in glass regenerator has become universal. Maithan offers the MGIS and MAGZIR range manufactured with high grade Sea water, sintered natural magnesia and zircon. These refractories are distinguished by their high density and resistance to alkali, sulphur, silica carry over and fume attack.
The product range comprises of gunning mixes including the highly successful MCL GUN95 for EOF hot repair, ramming masses produced with a blend of DBM and fused/sea water magnesia for coreless induction furnaces, EAF hearth, cold and hot steel launders, filling masses for EBT taphole and BOF taphole repair and mortars to complement the range of Basic shaped products.
