Zhengzhou Sunrise Refractory Co., Ltd. is a trusted global supplier of high-performance refractory materials, including fused cast AZS, magnesium silicate insulation boards, skid rail blocks, mullite bricks, zircon bricks, and more—engineered for durability, thermal efficiency, and industrial reliability.
Located in central China, Zhengzhou Sunrise Refractory Co., Ltd. leverages its strategic position near the Jingguang and Longhai railway intersection and Zhengzhou Xinzheng International Airport to serve clients globally.
We specialize in manufacturing a wide range of refractory products for glass furnaces, steel plants, cement kilns, and other high-temperature industrial applications. Our commitment to quality and innovation has enabled us to establish long-term partnerships with customers across Asia, Europe, the Middle East, and Africa.
Our product line includes fused cast AZS 33#, 36#, 41#, glass furnace fireclay bottom blocks, mullite bricks, zircon bricks, alumina bubble bricks, sillimanite bricks, corundum bricks, low porosity fireclay bricks, high alumina bricks, ramming masses, sealing materials, and building fireclay.
Engineered for performance, durability, and thermal efficiency in extreme industrial environments.
High structural strength, low deformation after sintering, excellent heat insulation, and damp-proof properties ideal for high-temperature insulation.
Durable skid rail blocks for steel discharging platforms and industrial conveyors. Resistant to thermal shock and mechanical wear.
High zirconia content for superior corrosion resistance in glass furnace applications. Excellent thermal stability and low porosity.
High alumina-silica content with excellent creep resistance and thermal shock stability. Ideal for kiln linings and burner nozzles.
High-density zirconium silicate brick with low thermal conductivity and excellent resistance to molten glass erosion.
High-purity alumina brick with exceptional hardness and abrasion resistance. Used in high-wear industrial zones.
Alumina content up to 85%, offering high refractoriness and load-bearing capacity under extreme temperatures.
Lightweight insulating brick with closed pores, providing excellent thermal insulation and low heat storage.
High-volume stability and resistance to thermal cycling. Ideal for areas requiring dimensional accuracy.
Engineered for minimal water absorption and high resistance to chemical attack in aggressive environments.
Fine-grained mix for seamless joint filling and repair in glass melting furnaces. Excellent sintering properties.
High-integrity seals for expansion joints and furnace doors. Resistant to high temperatures and mechanical stress.
All products undergo rigorous testing for density, porosity, thermal shock resistance, and chemical stability to ensure consistent performance.
Strategic location in Zhengzhou enables fast logistics and export to over 30 countries via air, sea, and rail.
Verified Chinese supplier with long-term partnerships and regular international client visits, including from Turkey, India, and Russia.
Sintered magnesia bricks (burned) are fired at high temperatures for maximum density and strength. Chemically bonded (non-fired) bricks use binders and are cured at lower temperatures, offering faster production and specific application flexibility.
Store in a dry, covered area to prevent moisture absorption. Avoid long-term outdoor storage. Stack bricks evenly to prevent cracking or deformation.
They offer high thermal shock resistance, excellent wear resistance, and stability in corrosive environments—ideal for heat storage systems and regenerative burners.
