Key Features of Monolithic Roof For Eaf Delta/ Vd/Vad

• Monolithic structure prevents undue expansion / contraction thus improving stability of the roof structure.
• Lower permeability of cast able structure restricts penetration of gases at high temperature.
• Coarse texture and dense matrix gives higher abrasion resistance.
• The Al2O3-Cr2O3 solid solution in the matrix imparts superior corrosion to slag ingress and restricts structural spalling.
• The controlled grain size distribution enhances thermal spalling at high meltdown temperature.
• The precast shape gives high strength and stability to the structure during up, down and swings of the roof.
