RUNZE Refractories
RUNZE Refractory Material Co. Ltd is a leading manufacturer and supplier of high-performance insulation solutions including ceramic fiber, calcium silicate, bio-soluble fiber, and sealing products.
RUNZE Refractory Material Co. Ltd (RZ Refractories) is a leading insulation refractory products manufacturer & supplier serving a wide range of industries where high temperatures exist. With advanced production capabilities and strict quality control, we deliver reliable thermal insulation solutions across global markets.
Our company operates four specialized factories: two dedicated to refractory ceramic fiber products, calcined kaolin, calcined bauxite, and calcium silicate board insulation products; one focused on ceramic fiber production line equipment; and another producing heat insulation and sealing products.
We manufacture a comprehensive portfolio of high-temperature insulation and refractory materials designed for durability, efficiency, and safety in extreme environments.
High-purity alumina-silica blanket for industrial furnaces, kilns, and boilers. Excellent thermal stability up to 1260°C.
Environmentally safe sealing tape for fire-rated glazing systems. Designed to expand under heat and seal gaps.
Rigid insulation pipe for high-temperature piping systems. Ideal for steam lines and industrial process equipment.
Precision nozzle for glass fiber production. Exceptional resistance to molten glass corrosion and thermal stress.
Prefabricated hot-face lining modules for industrial furnaces. Quick installation and excellent thermal performance.
High-alumina raw material for refractory castables, bricks, and monolithics. Consistent chemical composition and particle size.
Metakaolin product used in high-performance refractories, ceramics, and specialty applications. High reactivity and purity.
Fire-resistant sealing tape that expands when heated, creating a barrier against smoke and flames in glazing systems.
Complete turnkey systems for manufacturing ceramic fiber blankets, papers, and textiles. High-efficiency and automation-ready.
High-strength needle for non-woven fiber processing. Used in ceramic fiber and bio-soluble fiber production lines.
Woven and non-woven fabrics made from ceramic fibers. Used for gaskets, expansion joints, and thermal curtains.
High-temperature nozzle for glass and metallurgical applications. Excellent resistance to oxidation and thermal cycling.
Our commitment to innovation, quality, and customer service sets us apart in the global refractories market.
Decades of experience in high-temperature insulation solutions across steel, glass, petrochemical, and power industries.
Dedicated research team developing next-generation materials including bio-soluble and nano-enhanced fibers.
Products exported to over 50 countries with reliable logistics and multilingual technical support.
Comprehensive testing protocols and compliance with international standards (ASTM, ISO, GB).
Ceramic fiber products are widely used in industrial furnaces, kilns, boilers, incinerators, and high-temperature process equipment for thermal insulation, fire protection, and energy efficiency.
Yes, bio-soluble fibers are designed to dissolve in physiological conditions, reducing long-term health risks. They are classified as non-hazardous and are preferred in applications with potential human exposure.
Absolutely. We offer custom manufacturing for shapes, sizes, densities, and temperature ratings based on your technical requirements and application needs.
Calcium silicate board is rigid, high-strength, and ideal for structural insulation up to 1050°C. Ceramic fiber board is lighter, more flexible, and suitable for complex shapes with operating temperatures up to 1430°C.
Yes, our engineering team provides comprehensive technical support, including product selection, system design, and installation recommendations to ensure optimal performance.
