The Preferred Choice for High-Temperature Ceramic Kiln Linings
1. Alumina: ≥65%
2. Standard Size: 230*114*65mm
3. Benefits:
• The Stablizer in Oxidation
• Excellent Thermal Shock
• The Cost-Effective Performer
The sintered synthetic mullite brick (M series) includes three main models: M-65, M-70, and M-75, manufactured using high-purity synthetic mullite as raw material with alumina content ranging between 65%- 75%. Dominated by the 3Al₂O₃·2SiO₂ crystalline phase (content ≥90%), this product series demonstrates excellent high-temperature stability and thermal shock resistance, making it an ideal choice for upper structures of glass melting furnaces, channel cover plates, burner blocks, and other applications.
The sintered fused mullite brick (DM series) comprises two models: standard DM-75A and high-density DM-75B, produced from premium fused mullite raw materials through specialized sintering processes. Compared with conventional sintered synthetic mullite, this series features a denser micro-structure, higher cold crushing strength, and superior chemical corrosion resistance. The DM-75B model, through optimized formulation and processing, further enhances creep resistance while maintaining good thermal shock performance, making it particularly suitable for extreme working conditions such as high-alkali environments in glass furnace regen-erators, upper structures with relatively higher temperatures and greater mechanical stress.
1. Glass Industry (Regenerator Checkers)
Regenerator Middle & Lower Checkers: Commonly used in the middle courses of regenerators, offering a balance between performance and cost.
Key Advantage: Provides reliable resistance to thermal cycling and alkali vapor attack at a competitive cost.
2. Ceramic Industry – The Primary Application
High-Temperature Kiln Linings: The first choice for crowns, sidewalls, and car tops of tunnel kilns, shuttle kilns, and bell kilns firing sanitary ware, porcelain, and technical ceramics.
Key Advantage: Exceptional thermal shock resistance and volume stability prevent deformation and cracking during rapid temperature cycling, ensuring consistent kiln geometry and product quality.
