The refractory markets in traditional steel and building-material industries are gradually shifting toward stock-based competition. The new energy industry has become a key growth engine for refractory materials. Continuous commissioning of new production lines such as lithium-ion battery calcination kilns and photovoltaic glass melting furnaces has fueled rapid growth in demand for special refractory products.
Lithium-ion battery cathode calcination kilns and photovoltaic glass melting furnaces operate under unique working conditions. Beyond basic properties including high-temperature resistance and thermal-shock resistance, they impose strict requirements on refractories for low-impurity contamination, lightweight energy-saving performance and long service life. Trace precipitation of iron and alkali-metal impurities inside kilns directly degrades battery-material performance and causes stones and bubble defects in photovoltaic glass. Conventional metallurgical refractories can't meet such demanding operating conditions.
Market demand has driven upgrades in product mix. Orders for lightweight monolithic castables and high-purity refractory products have increased substantially. High-purity castables allow convenient on-site integral casting. Their good structural integrity lowers contamination risks caused by joints. High-purity alumina and mullite products feature tight impurity control, outstanding resistance to lithium-salt corrosion and molten-glass erosion. They suit different zones of lithium-battery sintering kilns and photovoltaic melting furnaces, effectively extending lining service life and cutting customers’operation and maintenance costs.
For high-temperature new energy kilns, refractories are no longer simple heat-resistant consumables. Custom-built products with low impurity levels and high stability represent core competitiveness. Through strict raw material control and formula optimization, we deliver reliable high-temperature lining solutions tailored for diverse operating conditions of lithium-battery and photovoltaic kilns, supporting stable and efficient production for downstream manufacturers.
