In September 2025, a batch of JM26 mullite insulation bricks from Kerui Refractory was shipped to Tanzania. These bricks will be used to insulate thermal equipment in local industrial kilns. Customers are very excited about the results of our products.
Product Features and Technical Specifications Purchased by a Tanzanian Customer
Kerui JM26 mullite insulation bricks are made from high-quality mullite raw materials using advanced production processes. Technical specifications include:
- Maximum operating temperature: 1400°C;
- Volume density: 0.7-1.0 g/cm³;
- Compressive strength at room temperature: ≥2-3.2 MPa;
- Thermal conductivity (350°C): 0.21-0.32 W/(m·K);
- Reburning line variation (1300°C x 12h): ±0.5%;
These technical specifications ensure product reliability and durability in industrial applications. The JM26 mullite insulation bricks feature a uniform microstructure and a well-balanced pore distribution, effectively reducing heat loss while ensuring sufficient mechanical strength.
Industrial Applications of JM26 Insulating Bricks
JM26 mullite insulation bricks are primarily used in the following applications in the Tanzanian market:
- Heating furnaces and heat treatment furnaces in the steel industry;
- Rotary kilns and preheaters in the cement industry;
- Tunnel kilns and shuttle kilns in the ceramics industry;
- Melting furnaces and annealing lehrs in the glass industry;
- Heat treatment equipment in the chemical industry.
These industrial equipment place stringent demands on refractory materials, requiring them to possess excellent thermal insulation, stable high-temperature volume stability, and superior thermal shock resistance.
