Refractory bricks are dense, pre-formed materials engineered to withstand extreme heat, thermal shock, and aggressive chemical environments. Made from high-purity raw materials such as alumina, silica, or magnesia, these bricks offer outstanding mechanical strength and dimensional stability even under continuous exposure to temperatures exceeding 1500°C. Their durability and structural integrity make them an ideal choice for lining high-temperature industrial furnaces, kilns, and reactors in industries like metallurgy, cement, and glass. With consistent quality and long service life, refractory bricks minimize downtime and ensure efficient thermal performance.
Refractory mortars are specialized high-temperature bonding materials designed to securely join refractory bricks and shapes. They play a crucial role in maintaining the mechanical strength and thermal integrity of furnace linings by forming seamless, heat-resistant joints. These mortars are formulated to resist thermal expansion, erosion, and chemical attack, making them suitable for a wide range of applications in steel plants, foundries, and other high-heat environments. Easy to mix and apply by hand or machine, refractory mortars enhance structural cohesion, reduce air leakage, and improve the overall efficiency and safety of refractory installations.
Refractory castables are unshaped materials that can be poured, troweled, or gunned into place, offering excellent versatility for a wide variety of high-temperature applications. Composed of refractory aggregates, binders, and additives, castables provide high strength, thermal insulation, and resistance to abrasion and corrosion after curing. They are ideal for custom linings in areas where traditional bricks cannot be easily applied, such as irregular geometries, repairs, or confined spaces. Refractory castables are widely used in boilers, incinerators, petrochemical units, and other high-heat zones, offering fast installation, cost efficiency, and reliable performance.
Refractory fiber materials, including ceramic fiber blankets, boards, and modules, are lightweight insulation solutions designed to withstand high temperatures while minimizing heat loss. These fibers offer low thermal conductivity, low heat storage, and excellent thermal shock resistance, enabling faster heating and cooling cycles that boost operational efficiency and energy savings. Easy to cut, shape, and install, refractory fibers are ideal for linings, expansion joints, seals, and backup insulation in various industrial furnaces and kilns. Their flexibility and lightweight nature reduce structural loads and make them especially valuable in applications requiring frequent maintenance or quick access.
At present, the company has advanced high temperature tunnel kiln, clay, high aluminum and not stereotypes refractories production line.
Our main products include clay bricks, silica bricks, high alumina bricks, mullite bricks, carborundum bricks, magnesite bricks, refractory castables, aluminum silicate fiber blankets, and various other refractory materials. We enjoy a strong reputation in the domestic industry, with solid sales performance and reliable service.
