In container, flat, specialty and insulation glass furnaces maintaining the integrity of alumina-based zones, from the superstructure to the bottom and forehearth is essential to ensuring consistent glass quality and long-lasting furnace campaigns.
Over time, these areas face corrosion, erosion, and material loss, especially in complex structural configurations, where traditional refractory maintenance and repair methods often fall short.
Repair Cast In Place Alumina was designed precisely for these challenges. Its self-flowing, self-leveling formulation makes it ideal for cold repairs, restoring the shape and performance of glass-contact zones quickly and safely without full refractory replacement.
A faster, safer way to repair glass furnaces
That’s why SEFPRO CARE® developed Repair Cast In Place Alumina, a pumpable, free-flow alumina castable that combines mechanical strength, corrosion resistance, and installation speed.
This self-flow material fills even the most intricate shapes, allowing smooth and homogeneous repairs in forehearths, superstructures, bottoms, and feeders: all while maintaining glass quality.
With worldwide and permanent stock availability, SEFPRO CARE® ensures a fast response with short lead times, minimizing downtime and production loss.
Precision and performance in every repair
Unlike traditional methods that require dismantling or replacing worn refractory blocks, Repair Cast In Place Alumina enables targeted, waste-free cold repairs.
When used together with SEFPRO’s 3D scan service, glassmakers can accurately evaluate corroded volumes, plan the intervention, and optimize material usage.
The product’s-controlled heat-up behavior guarantees a safe, gradual restart, protecting the refractory structure and ensuring high glass quality from the very first batch.
