In response to the growing need for high-durability refractory materials in the glass industry, Longketer Refractories has strengthened its supply of high-quality corundum mullite brick for glass-melting furnace working linings. This specialized brick offers outstanding high temperature resistance, corrosion resistance, and excellent alkali resistance, making it a preferred solution for glass producers aiming to extend furnace campaign life and reduce downtime.
Why Corundum Mullite Brick Is Critical for Glass Furnace Performance
Glass-melting furnaces operate under extreme conditions, with continuous exposure to high temperatures, molten glass corrosion, and alkaline vapor attack. The working lining directly contacts these aggressive environments, so choosing a reliable corundum mullite refractory brick is essential. Longketer's corundum mullite brick maintains structural stability at over 1700°C, resists chemical erosion from molten glass components, and withstands alkali-rich atmospheres that quickly degrade conventional refractory bricks.
In many glass plants, premature lining failure leads to costly production interruptions. With Longketer's corundum mullite brick for glass furnace applications, operators benefit from lower refractory replacement frequency and more consistent melting conditions, which directly improves glass quality and energy efficiency.
Corrosion Resistance and Alkali Resistance – Built for Long Service Life
Laboratory tests and in-field usage confirm that Longketer's corundum mullite working lining brick exhibits superior corrosion resistance compared to standard high-alumina or silica-based bricks. The dense matrix and optimized mullite phase reduce glass melt penetration, while the high corundum content provides excellent alkali resistance, preventing spalling and structural cracking. This makes the brick especially suitable for soda-lime glass furnaces, borosilicate glass tanks, and other alkali-intensive melting units.
Sufficient Supply & Full Customization Support
Longketer Refractories maintains a large production capacity for corundum mullite brick, ensuring sufficient supply even for bulk orders and urgent project timelines. Beyond standard dimensions, the company offers full customization – including special shapes, different corundum-mullite ratios, and precise tolerances – to match specific furnace designs and operating conditions. Customers can provide drawings or technical requirements, and Longketer's engineering team will tailor the corundum mullite working lining brick accordingly.
"We understand that every glass furnace has unique challenges," said a senior representative from Longketer Refractories. "That's why we keep our corundum mullite brick production flexible and well-stocked. Whether you need trial quantities or a full furnace lining package, we deliver consistent quality with short lead times."
