Industry Challenges and the Innovation of 5S

Rotary kilns, as dynamic furnaces, have long faced significant challenges in backup lining insulation. Although the industry has attempted to use traditional two- or three-layer Zig-Zag composite bricks, these materials suffer from the following issues:

• Poor Integrity: Differences in brick material properties lead to uneven thermal expansion, causing bricks to fall off and posing safety risks.

• Limited Insulation Performance: High thermal conductivity of traditional materials results in suboptimal energy savings.

• Complex Installation: Multi-layer structures increase installation difficulty and maintenance costs.

The Innovation of 5S Super Insulation Board:

The 5S Super Insulation Board revolutionizes rotary kiln insulation with its unique material and process design, enabling separate installation of the insulation layer and working lining. This ensures uniform and stable refractory lining integrity, while its high strength, low thermal conductivity, and ultra-low compression rate address the shortcomings of traditional materials, offering a breakthrough solution for rotary kiln insulation.

1. Significant Energy Savings: For a 5,000-ton-per-day cement kiln, using the 5S board can reduce the temperature by 100°C, saving 4,500 tons of standard coal equivalent in heat energy and up to 5 million RMB in fuel costs annually.

2. Quick Cost Recovery: The cost of the 5S board can be recovered within a few months through fuel savings.
3. Extended Equipment Life: High strength, low compression rate, and stable performance ensure long-term operation in extreme conditions.

4. Reduced Maintenance Costs: Ultra-low volume change rate and stable thermal conductivity minimize maintenance frequency and costs.

5. Lightweight Design: With a density of only 1.5g/cm³, the 5S board significantly reduces kiln weight, lowers equipment load, and improves installation efficiency
