Purging blocks are fitted at the bottom of the ladle to purge inert gas (Argon) for temperature homogenization, chemistry homogenization and absorbed gas removal. Dalmia GSB’s Purging Plugs have minimal risk of metal infiltration and offer high blowing capacity of 1000-1200 Lt./min.
Solutions for Purging Plug System
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.
High Alumina and Alumina Spinel based plugs.
Our Purging Plugs are based on tabular Alumina, Alumina Magnesia Spinel and Alumina Chrome based materials.
Slide Gate Systems are used to control the flow of molten steel from ladles. With a higher spigot area that helps in getting high face pressure, Dalmia GSB’s Slide Gate Mechanisms cause less chances of metal penetration and can provide almost double life than others.
With our wide experience, we have been manufacturing slide gate plates and nozzles (in both conventional and new generation designs) for all types of steel grades.
Solutions for Sliding Gate System
These are the solutions for Slide Gate System:
ALUMINA CARBON, ALUMINA ZIRCONIA CARBON, ALUMINA SPINEL CARBON and MAGNESIA CARBON BASED SLIDE GATE PLATES and NOZZLES
PLATES AND NOZZLES designed with inserts made of Zirconia/Spinel for higher life and specially crafted for new generation plates
TN MECHANISM – new generation slide gate mechanism, best suited for new generation plates that are user friendly and give higher life, with greater safety
Different qualities of slide gate plates and nozzles
Alumina-Carbon: High abrasion and corrosion resistance for Al or Si-killed steel
Alumina-Zirconia-Carbon: Suitable for high Mn and high Ca steel
Alumina-Spinel-Carbon: Applicable for high Mn and Al-killed steel
Magnesia-Spinel-Carbon: Superior corrosion resistance to high Ca (>30ppm) steel. Plates and Nozzles with inserts – Less permeable to liquid metal or slag due to dense structure
Good thermal shock resistance and high corrosion/erosion resistance
Cost effective and can provide double life over conventional products
TN Mechanism – Higher stroke length (180 mm for TN80 & 140 mm for TN60) designs with off center bore
Fitted in ladle bottom with the running adapter plate and cylinder by minor modification of bell crank system
Four point tightening system causing less possibility of crack during application
Octagonal geometry of plates gives minimum thermal stress during use
Higher spigot area of plate to get high face pressure causing less chance of metal penetration in between plates
Small & compact design for easy handling
Life of plates increase by 25-35% than existing lower generation mechanisms
Applicable for both direct and bell crank drive system
