Vishva Vishal Refractory Launches Upgraded Furnace Ramming Mass

Frequent refractory replacement due to high-temperature erosion, metal corrosion, and structural instability has long plagued metallurgical operations worldwide. These persistent issues significantly impact production efficiency and operational costs across foundries and smelting facilities.

The neutral ramming mass developed by Vishva Vishal Refractory Limited utilizes high-alumina bauxite as its primary aggregate, creating a robust skeletal structure that maintains exceptional thermal uniformity under extreme conditions. This engineered stability prevents thermal expansion-induced cracking and deformation, regardless of fluctuating smelting temperatures.

Volume stability remains a critical performance metric for refractory materials. This ramming mass demonstrates outstanding dimensional consistency at elevated temperatures, preventing structural degradation caused by volumetric changes. Its exceptional thermal stability ensures continuous operational reliability by maintaining lining integrity throughout prolonged service periods.

With remarkably low apparent porosity, the material effectively blocks molten metal infiltration - a primary failure mechanism in conventional refractories. This characteristic significantly improves operational safety and process reliability in demanding metallurgical applications.

The formulation demonstrates exceptional resistance to mechanical wear and impact damage, maintaining lining performance even under severe processing conditions involving abrasive materials and intense mechanical stresses.

• Particle Size: 0-4 mm (precisely controlled for optimal compaction density)
• Density: 3.0 gm/cc (enhanced structural integrity)
• Sintering Range: 1260°C (initial) to 1650°C (final)
• Maximum Service Temperature: 1750°C
• Chemical Composition: 82-86% Al₂O₃, 12-16% MgO, ≤1% SiO₂

The material's high alumina content ensures superior refractory characteristics, while controlled magnesium oxide levels optimize slag resistance. Strict limitation of silica content prevents undesirable high-temperature reactions with basic substances.
