Glass Furnace Refractories for Long Campaigns
Glass furnaces run for years between rebuilds, so every refractory choice has to last a whole campaign. McKeown supplies glass furnace refractories for the melter, crown, and regenerators, with each material matched to the glass you make and how you fire it.
Melter and Glass-Contact Refractories
Materials that touch molten glass must resist corrosion without releasing stones or blisters into the product. We supply fused-cast AZS and zircon refractories for sidewalls, throats, and other high-wear glass-contact areas.
Crown and Superstructure
Silica brick remains the standard for crowns thanks to its strength and volume stability at high temperatures. We also supply high-alumina and fireclay brick for superstructure and lower-temperature areas.
Regenerators and Insulation
Regenerator checkers go through repeated heating and cooling while taking on alkali-laden exhaust. We supply magnesia and MgO-chrome products for the upper checker packs and fireclay for the cooler courses, plus insulating materials that reduce heat loss across the furnace.
