Explore our top-performing ODM refractory bricks customized to meet strict American industrial standards and high-temperature furnace specifications.
The United States boasts one of the most advanced and demanding manufacturing sectors in the world. From the glass manufacturing hubs in Ohio and Pennsylvania to the massive petrochemical refining plants along the Gulf Coast of Texas and Louisiana, high-temperature operations require materials that can withstand extreme thermal, chemical, and mechanical stress. Zirconia Refractory Bricks have emerged as the gold standard for these demanding environments due to their exceptional melting point (exceeding 2600°C), superior resistance to acid and basic slags, and low thermal conductivity at elevated temperatures.
As US industries push for higher operational efficiencies and transition toward low-carbon technologies, the demands placed on furnace linings have intensified. Advanced glass-melting tanks, waste-to-energy incinerators, and steel processing vessels require ODM (Original Design Manufacturing) zirconia bricks that are tailored to specific geometric and chemical requirements. By customizing the zirconia content (ZrO2) and blending it with alumina and silica (forming AZS refractories), factories can target localized wear zones, significantly extending the lifespan of industrial kilns and minimizing expensive operational downtime.
Modern US manufacturing facilities demand precise material properties, strict adherence to ASTM standards, and environmental sustainability.
Tailored ZrO2 concentrations and brick geometries designed using advanced thermal modeling to match specific US furnace blueprints and operating conditions.
As US glass and steel plants transition to clean-burning hydrogen fuels, our zirconia refractories resist the increased water vapor and thermal stress associated with hydrogen combustion.
Exceptional chemical inertness makes our zirconia and AZS products highly resistant to corrosive molten glass, volatile alkali vapors, and aggressive metallurgical slags.
Zhengzhou SK Refractory Co., Ltd. (SK), located in Xinmi, Zhengzhou, China, has dedicated over twenty years to delivering high-performance, reliable solutions that redefine durability and efficiency for our clients worldwide. Founded on the principles of innovation, quality, and sustainability, we serve key sectors including steelmaking, cement production, non-ferrous metallurgy, glass manufacturing, and petrochemical processing.
Our global footprint spans across major industrial hubs, with the United States representing one of our primary markets. We understand the stringent quality controls, logistics requirements, and technical specifications demanded by American procurement managers and engineering firms.
Contact Our ExpertsFrom modern recycling plants to traditional heavy manufacturing, our zirconia refractories are engineered for specific US industrial operations.
The US glass industry, producing container glass, flat glass for construction, and specialty fiber optics, relies heavily on high-durability linings. In the critical contact zones where molten glass meets the refractory wall, standard bricks fail rapidly due to erosion. Our sintered and fused AZS (Alumina-Zirconia-Silica) bricks provide the ultimate barrier, preventing glass contamination and ensuring furnace campaigns last for over 10 to 15 years.
In the vast refinery complexes of Texas and Louisiana, secondary reformers and gasifiers operate under elevated pressures and temperatures exceeding 1400°C in reducing atmospheres. High-purity zirconia bricks resist hydrogen attack and carbon monoxide disintegration, maintaining structural integrity where alumina-silicate refractories degrade.
Municipal waste-to-energy plants in states like New York and Massachusetts deal with highly variable combustion materials. The resulting flue gases contain volatile heavy metals, halogens, and alkalis. Zirconia-mullite and silicon carbide composites provide the necessary abrasion and chemical resistance to withstand these aggressive municipal and industrial waste streams.
US steelmakers in Indiana, Ohio, and Michigan utilize advanced continuous casting processes. The flow control components, including tundish nozzles, slide gate plates, and shroud tubes, experience severe thermal shock and erosion from molten steel. Our ODM zirconia insert nozzles offer stable bore diameters throughout long casting sequences, improving steel cleanliness and operational safety.
As the US clean energy sector expands, manufacturing solid oxide fuel cells and high-temperature technical ceramics requires sintering kilns operating above 1600°C. High-purity zirconia setter plates and furnace linings provide a chemically inert setting that prevents reaction with the fired electronic components, ensuring ultra-pure processing environments.

Our laboratory is equipped with state-of-the-art testing equipment to guarantee that all products shipped to the US meet or exceed ASTM and ISO standards.
Learn More About Our Quality StandardsUnderstanding the technological and environmental shifts shaping the future of high-temperature industrial manufacturing.
With the US Department of Energy promoting industrial decarbonization, factories are upgrading their insulation systems. High-performance refractories like zirconia-containing bricks allow furnaces to operate at higher temperatures with less heat loss. Combining dense zirconia working linings with lightweight mullite insulation bricks creates a thermal barrier that reduces fuel consumption and carbon footprints.
The integration of IoT sensors and AI-driven predictive maintenance is growing in US steel and glass plants. Zirconia bricks, with their predictable wear rates, are increasingly paired with thermal imaging and sensor systems. This allows operators to monitor lining thickness in real-time, preventing catastrophic failures and optimizing the timing of furnace rebuilds.
Sustainability mandates in the US are driving demand for recyclable refractory materials. SK Refractory is actively researching and developing methods to reclaim and process spent refractory linings. By incorporating high-quality recycled aggregates back into specific non-critical applications, we help US clients meet their zero-waste-to-landfill goals without compromising mechanical performance.
As gas-fired kilns transition to hydrogen blends, the chemical composition of the furnace atmosphere changes, resulting in higher humidity levels. Zirconia-based refractories exhibit excellent stability under hydrothermal conditions, making them the preferred choice for next-generation green steel and clean glass operations across North America.
Our obligation is to supply high-quality refractory materials and services to achieve a long lifetime for high-temperature furnaces. SK Refractories constantly improves to provide better products and services to customers worldwide.
