Kerui Refractory is pleased to announce its participation in the 32nd Metall-Expo 2026, the international exhibition for the metallurgical industry in Saint Petersburg, Russia. We warmly invite customers, industry professionals, and business partners to visit us at Booth G619 to explore our refractory products and … Read More
Self-leveling cement is widely used to create smooth, even surfaces before the installation of flooring materials. Depending on the formulation, calcium aluminate cement can serve as an important hydraulic binder in self-leveling compounds, helping provide rapid setting, early strength, and controlled hardening. Unlike conventional cement-based … Read More
Glass melting furnaces operate under extremely high temperatures and aggressive chemical conditions. The refractory lining is continuously exposed to molten glass corrosion, thermal shock, mechanical stress and high-temperature erosion. Choosing the right refractory materials for different furnace zones is essential to improve furnace campaign life, … Read More
Fiberglass furnaces are designed for continuous glass melting and fiber drawing operations. Compared with rock wool and basalt melting furnaces, fiberglass furnaces require cleaner melting environments, more stable temperatures, and higher resistance to glass liquid contamination. Because furnace stability directly affects fiber quality and production … Read More
Basalt fiber furnaces operate under high-temperature melting conditions and are continuously exposed to molten basalt erosion, iron-rich slag attack, thermal shock, and chemical penetration. Compared with conventional glass furnaces, basalt melting furnaces usually face more aggressive corrosion conditions because basalt raw materials contain higher FeO, … Read More
Rock wool furnaces operate under continuous high-temperature conditions and are exposed to severe slag corrosion, thermal shock, molten material erosion, and mechanical wear. Because raw materials such as basalt, dolomite, and industrial slag often have unstable chemical compositions, the furnace lining is under constantly changing … Read More
Vanadium pentoxide (V₂O₅) furnaces operate under highly aggressive conditions, including strong oxidation, chemical corrosion, and high temperatures. As a result, selecting the right refractory materials for each furnace zone is essential to ensure stable operation, longer service life, and lower maintenance costs. Unlike general industrial … Read More
In industrial projects involving corrosion and high temperatures, two materials are often confused: acid resistant bricks (acid proof bricks) and acid refractory bricks used in acidic environments. Although they may seem similar, these two products are designed for completely different working conditions and are not … Read More
Neutral refractory materials play a key role in industrial furnace linings because they maintain chemical stability in both acidic and basic environments. Unlike strictly acidic or basic refractories, these materials adapt well to complex or changing furnace conditions, making them widely used in industries such … Read More
Acidic refractory materials are designed to perform in environments where acidic slags (SiO₂-rich) dominate and basic components such as CaO or MgO are limited. These materials provide excellent chemical stability and high-temperature resistance, making them widely used in glass furnaces, coke ovens, ceramic kilns, and … Read More
