An RH Vacuum Degasser is an equipment for swift degassing of large amounts of molten steel. It is used for mass production of high purity steel, realizing decarburization and heating by injecting pure oxygen gas into the vacuum vessel.
Solutions for RH-Degasser
We offer a range of high performance Directional Purging Plugs with customized design and secondary metallurgical operations which have been adopted by various steel plants.
These are the solutions for RH-Degasser:
HIGH ALUMNIA and ALUMNIA SPINEL BASED PLUGS
Our PURGING PLUGS are based on tabular Alumina, Alumina Magnesia Spinel and Alumina Chrome based materials
High resistance to slag and abrasion. High thermal shock resistance
Low RTE values Numbers of purging slits vary from 20-30
Vacuum Argon Decarburization (VOD) / Argon Oxygen Decarburization (AOD) is primarily a process used for making stainless steel. In VOD, the vessel works with oxygen injection and subsequently with vacuum treatment for decarburization, while in AOD, the initially melted metal is transferred to the AOD vessel where the process of decarburization, reduction and desulphurisation takes place.
A Ladle Furnace or Ladle Refining Furnace is used to refine the quality of liquid metal to make high quality steel by raising temperature and adjusting the chemical composition of molten metals.
Solutions for VOD Unit
These are the solutions for VOD Unit:
MAGNESIA DOLOMITE BRICKS
DIRECT BONDED and RE-BONDED FUSED BRICKS
MAGNESIA CARBON BRICKS
HIGH STRENGTH MAGNESIA CHROME and DIRECT BONDED MAGNESIA CHROME BRICKS
REBONDED FUSED GRAIN MAGNESIA-CHROME
SPECIALLY DESIGNED PURGING PLUG
Our Magnesia Dolomite Bricks; and direct bonded & re-bonded fused Magnesia Chrome Bricks are specially made to resist the severity of VOD operations such as high operating temperature, low basicity slag and severe turbulence of stee
Magnesia Dolomite Bricks for AOD converters made from synthetic Magnesia Dolomite Clinker have high density and purity, and hence exhibit uniform physical, chemical and thermal properties
These bricks also show excellent hydration resistance, high corrosion resistance to secondary refining slags with low basicity and high hot abrasion resistance to metal
MAGNESIA CARBON BRICKS ALUMINA MAGNESIA CARBON BRICKS LOW CARBON AND ALUMINA SPINEL BRICKS for work linning
CHROME MAGNESITE AND FIRECLAY for safety linings
BASIC GUNNING and RAMMING MASSES
CONVENTIONAL AND LOW CEMENT CASTABLES for safety along with peripheral lining
PRECAST HIGH ALUMINA CASTABLE BLOCKS
ALUMINA SPINEL BRICKS for Ladle and HIGH ALUMINA PLASTIC for closing the retainer
Our Magnesia Carbon Bricks with improved carbon bonding and special characteristics like low coked porosity, high coked cold crushing strength, excellent corrosion, erosion, thermal shock & oxidation resistance and high hot strength are suitable for different zones depending on operational severity
Our Alumina Magnesia Carbon Bricks with controlled residual expansion are recommended for the middle zone and bottom of the Ladle Furnace to prevent joint erosion and metal penetration
